Introduction

The term ‘Fish Marketing’ is composed of two broad meaning term ‘Fish’ and ‘Marketing’. Before discussing the methodological issues of fish marketing data analysis, we must understand the broader meaning of it as both words are being used frequently with a précised meaning. Google dictionary explains fish as ‘A limbless cold-blooded vertebrate animal with gills and fins living wholly in water’. But ‘fish’ as a component of fish marketing or social science study, means a product and a variety of product, which has different time, space and form utilities for consumers.

The word ‘marketing’ is not merely buying and selling of fish, rather it connotes a series of activities involved in moving goods or services from point of production to the point of consumption. So ‘fish marketing’ is defined as physical and institutional set up to perform all activities involved in the flow of fish, fish products and services from the point of initial fish production until they are in the hands of ultimate customers.

It includes assembling, handling, storage, transport, processing, wholesaling, retailing and export of fish and fishery products as well as accompanying supporting services such as market information, establishment of grades and standards, community trade, financing and price risk management and the institutions involved in performing the above functions.

It is desired to have an efficient and well planned distribution networkso that fish and fishery products move from the place of landing or production to the place of consumption at cheapest cost with quality –intact, ensuring the maximum price realization to the farmers or fish producers. It is really challenging to the public agencies involved to meet the requirements of all three major players, viz., fishermen or fish farmers, consumers and traders.

It includes all activities involved in creation of time, place, form and possession utility. Philip Kotler explained marketing as the science and art of exploring, creating, and delivering value to satisfy the needs of a target market at a profit. ‘Fish marketing’ is different from marketing of other goods and services and even differs a bit from marketing of variousagricultural goods and services.

Introduction

The Aquaculture and fisheries sector in India is a multi-disciplinary sector that provides food security, employment, economic gains, and socio-economic upliftment for those involved in fish exploitation, production, and processing. Sustainable fishing practices, improvements in fish breeding and husbandry technologies, along with the introduction of new species, have helped increase production levels through small-scale rural aquaculture, largely through governmental and non-government organizations.1Aquaculture and f isheries entrepreneurship are crucial for youth economic empowerment in India, providing and promoting sustainable development and employment opportunities within the fisheries sector. Technological advancements in aquaculture can enhance productivity, optimize resource utilization, minimize environmental impacts, and improve profitability. Aquaculture and fisheries entrepreneurship can promote environmental sustainability by adopting eco friendly practices and establishing strong market linkages. It has significant potential in rural areas where employment opportunities are limited, reducing migration and contributing to local economic growth. Government initiatives and policies that promote entrepreneurship, youth development, and sustainable fisheries are instrumental in supporting young individuals interested in aquaculture.

Fisheries and aquaculture sector is highly diverse (Figure 1) and an important source of livelihood for about 28 million fishers and fish farmers in the country. India is the 3rd largest fish producing country with about 8% of global fish production. Globally, India stands 2nd in aquaculture production and is one of the top shrimp-producing and seafood-exporting nations. The fisheries sector in India has shown a sustained annual average growth rate of 8.61% for the 8-year period from 2014–15 to 2021–22 (at constant prices). The sector has reached a record fish production of 162.48 lakh tonnes in FY 2021–22 and has immense potential for growth.

Introduction

Dried fish is a staple food for various communities and considered a ‘hidden’ sub-sector within small-scale fisheries. Dried fish defined broadly as aquatic animals preserved using simple techniques such as sun-drying, salting, fermentation, and smoking that permit storage as foods at ambient temperature for extended periods without specialized packaging (Belton et al., 2022). The nutritional quality of dried fish remains intact, sometimes retains higher quality standards compared to fresh fish (Faruque et al., 2012). Fish drying is an age old practice followed for preservation of fish. Over the years, it has grown from a subsistence occupation to a full flourishing business (Sanjeev et al., 2020). This traditional method is followed for the preservation of fish especially in rural areas (Chakrabarti and Varma, 1999). Drying method is considered as the least expensive method of fish preservation (Balachandran, 2001). Dried f ish attracts greater demand during fishing ban period or lean seasons, as the fresh fish availability is relatively low (Das et al., 2013). Dry fishes are used as food and the deteriorated Dried fish business can play an important role in the national economy in multiple ways including minimizing post-harvest losses of fish providing a source of animal protein, enlarging livelihoods, utilizing idling labor into the production process and as a dish, especially for rural poor (Wickrama et al., 2021). Dry fish marketing chain begins with a farmer (dry fish producer) and concludes with the final consumer with several intermediaries in between. These marketing middlemen provide services for producing, assembling, loading, packaging and transporting dry fish, resulting in cost increase at every stage of marketing processing (Mallick et al., 2022). Dried f ish are usually low in price, easily divisible and can be stored and transported for accessibility by the poorest and most vulnerable communities throughout the year. Dried fish can therefore play a vital role in nutrition security. In India, dry fishes are widely sold at local markets and commercially important species are also exported to other countries (Immaculate et al., 2013). Dry fish are used for production of poultry/fish feed. Today, dried fish products business provide employment for millions of people, particularly women, who are the majority of the fish- drying workforce in many locations (Belton et al., 2022).

An Overview of Fish and Shellfish Health Management in Aquaculture in India

Aquaculture in India in particular freshwater fish culture comprised mainly of Indian major carp cultivation has a long history. Since 1980s commercial carp culture expanded, particularly in Andhra Pradesh and in few years became an Asia model. Then on, it is slowly and steadily expanding to different parts of the country particularly Punjab, Haryana, West Bengal, Orissa and Tamil Nadu and Karnataka. Of late, culture of Pungasius (Basa) has come up on large scale in AP. In addition, there is also growing small scale commercial cultivation of catfish, murrels, tilapia and freshwater prawn(Macrobrachium rosenbergii). Aquarium fish breeding is also expanding to establish itself as an industry in India.

Brackish water culture has been practiced traditionally in India in Pokkali fields of Kerala, Bheries of West Bengal and Ghaznis of Karnataka since hundreds of years. From 1990 onwards, commercial shrimp culture came into existence along the coasts of India. High export value, support from government and short culture period encouraged private entrepreneurs to pursue shrimp farming in a big way. There is vast potential for fish culture in brackish water and at the present efforts are on to popularize culture of Asian seabass, mullets, Eutroplus and milk fish. Mariculture is still at infancy but increasing at a slow and steady rate.

Aquaculture health management has to be viewed from the incidences and outbreak of diseases due to growth and expansion of the industry. Aquaculture has expanded tremendously in the last three decades, growing at 6-7 % annually. Contribution of fish production from aquaculture in the country is around 60 % compared to 10 % it was 40 years ago. In few years to come, aquaculture contribution may go up to 80 % of total fish production. Today 2.43 m ha of freshwater and 1.15 m ha of brackish water are under culture. In addition, 8.62 m. ha of irrigated inland area mainly in Haryana, Maharastra and Karnataka which have become saline and unsuitable for agriculture are slowly being reclaimed for aquaculture. Farmers are growing acclamatized saltwater fish and shrimp spp in inland saline waters and a shift like this may favour pathogens with different virulence to cause disease. Overall, it can be seen that in addition to increased conventional areas in fresh and brackish water, aquaculture is being practiced in unconventional areas like saline soils. Performance of fish and shellfish in these non conventional water bodies in the long run needs to be studied from their health point of view.

Introduction

Agriculture is the back bone of Indian economy. About 18.8 percent (2021-22) of the national income originates from the agriculture sector. Approximately 60 percent of India’s population is directly or indirectly dependent on agriculture for livelihood. A large number of important industries like jute, textiles, edible oils, tobacco, sugar etc. receive the raw materials produced by agriculture sector. India occupies second position in the production of fruits and vegetables in the world after China (National Horticulture Database 2019 2020) It is grown almost in all the states of the country.

Cauliflower (Brassica oleracea L. var. botrytis) like all other Brassicaceae family crops has descended through introgression, mutation, human selection and adaptation from a single wild predecessor Brassica oleracea L. var. sylvestris which is still found growing in western and southern Europe and North Africa. The name cauliflower consists of two Latin words namely ‘caulis’ means cabbage and ‘floris’ means flower. It is grown throughout the country for its highly suppressed ‘prefloral fleshy apical meristem’ called “Curd” which is used as vegetable, soup and for pickling (Choudhury, 2006). Cauliflower is the pride of cole crops because of its good taste, flavour and nutritional value. It contains good amount of vitamins like vitamin A, vitamin C and fair amount of proteins and fibers. The cauliflower is also a good source of minerals like Ca, Mg, P, Fe, Na, and S.

Introduction

The most significant commercially grown fruit crop in the country is the mango (Mangifera indica L.), which belongs to the Anacardiaceae family. It’s known as the “king of fruits.” Mango cultivars can be found in the greatest variety in India. Mango farming is thought to have begun in South East Asia. Since about 6,000 years ago, mango has been grown in south Asia.Mango is native to South Asia, from where it has been distributed worldwide to become one of the most cultivated fruits in the tropics.

The major mango-growing states are Andhra Pradesh, Uttar Pradesh, Karnataka, Bihar, Gujarat and Tamil Nadu. Andhra Pradesh rank 1st in area, whereas Uttar Pradesh rank 1st in production and productivity. Andhra Pradesh, Uttar Pradesh, Bihar, Karnataka, Maharashtra, West Bengal and Gujarat together contribute for about 82% of the total production in India.

India to become the second largest fruit producer in the world, after china, with a production of 102481 thousands metric tonnes of fruits from an area of 6930 thousands hectares in 2020-21.The fruit is grown in India, the total area under mango cultivation was 2317 thousand hectare with an annual production of 20386 thousand metric tonnes.(NHB 2020-21).

Mango is well adopted in tropical and sub-tropical climates but it can be grown up to 1,100 meters above sea-level. There should not be humidity, rain or frost during flowering. The temperature between 24 and 270C is ideal for its cultivation. Higher temperature during fruit development and maturity gives better quality fruits. The areas expressed frequent showers and high humidity is prone to many pests and diseases. Thus it can grow best in regions with a rainfall between 25cm and 250 cm. Regions having bright sunny days and moderate humidity during flowering is ideal for mango growing.The farmers 92.20 per cent had problems of pests in their mango trees. The most common pests were the mango seed weevil 48.10 per cent, fruit fly 36.40 per cent, trips 1.30 per cent, aphids 1.30 per cent and the most common diseases were the powdery mildew 46.80 per cent, anthracnose 18.20 per cent and scab 2.60 per cent (Gitonga,2010).

Introduction

NITI Policy Paper No.1/20017 reveals details of the concept and time frame as how to double the income of the farmers. The policy paper emphasizes in increase in agriculture productivity, improvement in total factor productivity, diversification towards high value crop, and increase in crop intensity, increasing terms of trade for farmers and shifting cultivators to non-farm and subsidiary activities. The well thought and planned program for doubling the income of the farmers reflecting dream or reality. We have farmers of different types like, small. Marginal and large farmers, resource rich and resource poor farmers, farmers of irrigated and non-irrigated zones, tribal and non-tribal farmers , trained and untrained farmers and progressive and non-progressive farmers. The farmers and their economic structure are quite different from place to place even within district. NSSO data on consumption expenditure survey (2011-12) reveal that more than one-fifth of households with self employment in agriculture and their principal occupation were having income less the poverty line.

Milk Production Scenario

Milk is primary source of protein and lactoseDairy farming is considered to be a whole environment of reciprocal relations and dependency reproduction and protection of social values. In worldwise dairy cows count up to 264 millions producing 600 million tones of milk every year. The global average for milk production is approximately 2200 litters/cow. Cattle population of world is 1009.69 millions heads (FAO, 2019) and highest milk producing countries are India, USA, China, Pakistan and Brazil. In case of consumption of milk India tops in the world followed by EU, USA and China. The per capita consumption of milk is highest in the country of Belarus followed by Ukraine and New Zealand. India is ranked 7th in the world in this respect. In India total cattle population is 306.70 millions. The state of Odisha constitutes 1.19% of the total cattle population of India. The level of milk production of India is reported to be 198.2 metric million tones. The per capita availability of milk in India is 427 gms/day (2021) and highest being in Punjab followed by Rajasthan. In case of Odisha the per capita milk availability is 143 gms and in milk production the district Cuttack top the list followed by Ganjam and Jagatsinghpur.

Introduction

In view of the present Indian agriculture scenario, farmer producers organisations (FPOs) are emerged as a most appropriate institutional form to mobilize small and marginal farmers ,improved their access to technology, inputs and markets. As per the report of National Council on Farmers, these organisations are mainly promoted to combine the advantages of decentralized production and centralized services, post harvest management, value addition and marketing. (NCF,2004). In order to meet the dream of Atmanirbhar Bharat and to make farmers atmanirbhar, Farmer Producers’ Organizations (FPOs) is an appropriate form to mobilize them. Recently Government of India has announced a budgetary provision of 4496.00 crore for five years for promotion of 10,000 FPOs.(Cabinet Committee on Economic Affairs,CCEA2020)

Also to improve agricultural productivity and income of the farmers, it is necessary to develop an entrepreneurial culture among the member farmers of an organisation. To make this organisational approach more successful, member farmers need to develop planning ability, decision making abilitiy, managerial qualities ,scientific attitude, organisational skills, participatory skills etc. The member farmers as an agripreneur should possess knowledge about improved production techniques, markets, consumer preferences , schemes, credit availability, policy advocacy to enterprise effectively under FPO.

Introduction

Novel Corona Virus 2019 (COVID 19) has impacted the human race very badly than any other disease in twenty first century. Almost every country on this planet was affected by this virus. The condition is more severe in developed countries.

So when it All Started?

There were reports that the medical professionals of Wuhan in China informed the government that there is some mysterious pneumonia like disease which is spreading very fast and affected the doctors and other paramedical staff who are attending the patients. When the situation became serious it was declared as outbreak of epidemic and first case of COVID 19 was declared in Wuhan China on 31st December 2019. Wuhan is one of the main business centres of china and there was regular movement of domestic and international visitors to that place. Till the problem was identified and communicated to other agencies, the spread of virus was already there in other parts of china and world specially Europe and USA.

World Health Organisation (WHO) declared COVID 19 as pandemic on 11 February 2020. Countries like USA criticized WHO for delay in identifying the disease and declaring it a pandemic.The damage was already done due to its spread in other countries. In India first reported case of COVID 19 was on 30th January at Kerala. However, considering the possible danger of this disease, Indian Government took primitive measure to contain the spread of Virus and announced Nationwide Lockdown 1.0 on 23rdMarch 2020. Similarly, Lockdown 2.0, 3.0, 4.0 were announced on 14 April, 3rd May and 17th may respectively.

Introduction

India is bestowed with a lot of potentials to produce a variety of organic products due to its diversified agro-climatic regions and this is very true in case of Dehradun district of Uttarakhand. It offers a variety of geographic locations suitable for cultivating various food crops such as: fruits, vegetables, food grains etc. Globally, organic farming is cultivated in an area of 57.80 million ha. However, India accounts for just 2.59% of the area. The organic farming is followed in India in almost all the regions with three states Madhya Pradesh (34.34%), Maharashtra (13.19%) and Rajasthan (11.67%) accounting for about 59% of the total organic area of the country. The cultivated land under certification has substantially increased from 1.74 lakh ha in the year 2005-06 to 1.78 million ha in the year 2017-188 (https://www.researchgate. net/publication/338209816_Impact_of_farmer_producer_organization_on_ organic_chilli_production_in_Telangana_India) Agriculture and its allied sectors are the largest source of livelihoods in India. However, India still has many growing concerns. As the Indian economy has diversified and grown, agriculture’s contribution to GDP has steadily declined from 1951 to 2011. (Source: http://www.fao.org/india/fao-in-india/india-at-a-glance/). One of the main reasons is due to the lack of competence in Indian farmers for selling the crop in remunerative prices in the market. Some of the critical constraints and bottlenecks are lack of infrastructure for storage, transportation, quality control, packaging, price risk management, cool chains, market led extension, and framework for promotion of contract farming (Gohain, 2018). Realizing these issues Government of India under the Department of Agriculture and Cooperation identified Farmer Producer Organization (FPO) as the most appropriate institutional form to mobilize farmers and build their capacity to collectively leverage their production and marketing strength(Ministry of Agriculture, 2013).For analyzing the potential, importance and contribution of FPO in the agriculture sector, the present study aims to discuss the role of FPO in uplifting small and marginal farmers and its impact on the basis of the project undertaken by Silgur Bizat SwayattSahkarita FPO in Dehradun district of Uttarakhand.

Introduction

India has been advancing excessively in terms of workforce engagement as a lot of women have started seeking space in the business arena. The new age has given way to a new trend of entrepreneurshipwhich is flourishing without the quantification of gender. Needless to say, India has been dealing with a very bad history of patriarchal class arrogance and work division that cannot fully provide all the freedom to women who want to prosper in their professional lives.

The female entrepreneurs have to undergo a lot of obstacles right from the initiation of the idea till the plan operates. Sometimes, the existence as a women itself comes with a baggage of responsibilities. Indian women are bound to fulfill their responsibilities towards their family, community and work, balancing everything equally and in an efficient manner.

The conventionalism, ethnicity, social and cultural principles, parenthood, the tag of feeblest sex and insecurity curb the confidence of women in comparison to their male counterparts. Even though there have been considerable changes found in the women dwelling in urban areas, the rural women still have numerous hindrances blocking their path. The perceptive of the opponent sex is irrational in rural areas due to the lack of education and it becomes hard for the women to resist men in such cases.

The Indian customary draws a thin line between the capability and responsibility allotted to different gendersMohsen B., and Zouari S. (2014). It has even threatened the employment chances of females in the traditional and eccentric sphere of fiscal exercises. The present scenario has not broken the undeterred confidence of women who sought to make a career in business, since the last decade. With the alteration in technology, globalization and rivalry accentuation has made the operation of business more multifaceted and vibrant.

Globally, antimicrobial resistance (AMR) is an important public health and development threat (WHO, 2020). Being one of the top 10 global public health threats, the ever-increasing rates in the occurrence of drug-resistant bacterial infections have become a grave public health concern for the governments (Laxminarayan et al., 2013). Moreover, such infections would be difficult to treat and therefore can lead to worse clinical outcomes (Laxminarayan et al., 2013). Worldwide, each year about 700,000 people die from antimicrobial resistant infections and the mortality figures are projected to reach 10 million/ year by 2050 (O’Neill, 2016). The crude infectious disease mortality rate in India is more than 400 per 100,000 persons and at least 23,000 deaths in adults and 58,000 neonatal deaths per year are caused by AMR bacteria (Laxminarayan and Chaudhury, 2016). A 2017 estimate puts the cost of developing an antibiotic at around US$1.5 billion (Towse, et al. 2017). Meanwhile, industry analysts estimate that the average revenue generated from an antibiotic’s sale is roughly $46 million per year. “That’s tiny and nowhere near the.

Microbial Resistance Mechanism

Huge use of antibiotics in nosocomical environment has lead to the occurrence of multidrug resistance mechanism by microorganism against particular antibiotics (Munita et al., 2016; Zhao et al., 2020). Main operation includes chemical modification, efflux pump through passivation, modification of drug targeting gene and systemic elimination of antibiotics as many of them can form biofilm (Rajput et al., 2018) which can show extreme resistance. Chemical and enzymatic mechanism can include inactivation, activity loss, degradation and derivatizaton of antibiotics chemical group (Liu et al., 2019). Best idea may include production of enzymes or they can also expel antibiotic to efflux pump. Antibiotics drug efflux resistance can be accomplished by drug efflux pump playing an important role in microbial resistance. A different type of efflux pump system has been identified that include lipophilic and hydrophilic efflux system targeting the drug at different chemical properties (Wasaznik et al., 2009; Kumar et al., 2012). Another strategy adopting in resistance mechanism is modification of drug targeting gene. This mechanism makes the changes in drug to lose its target through drug targeting gene modification. Another important resistance mechanism is effectiveness of antibiotics by interfering with the target site. Therefore, bacteria has evolved different mechanism that include target site protection. A bactericidal role played by beta lactum antibiotics in inhibition of mucopeptide synthase and bacterial penicillin binding protein (PBP) in cell wall transpeptidation reaction that prevents the formation of complete call wall and hence dies (Sauvage et al., 2016). Bacteria also developed its own strategies to cope up with the environmental stress that can also include human body. In course of gaining the advantage bacteria needs to compete for nutrients and to keep away from the molecules produced by other competing organism (Zhao et al., 2019). Recently researchers have found the importance of biofilm resistance in bacteria. Bacterial biofilm resistance produce by complex and systematic drug resistance mechanism.

Introduction

Antibiotic-resistant bacteria are a major cause of health care-associated infections around the world, and resistance has also emerged in infections in the wider community. Infections caused by multi resistant organisms significantly increase morbidity, mortality, and health care costs. Molecular analyses have revealed that widespread multi resistance has commonly been achieved by the acquisition of preexisting determinants followed by amplification in response to selection. The capture, accumulation, and dissemination of resistance genes are largely due to the actions of mobile genetic elements (MGE), a term used to refer to elements that promote intracellular DNA mobility (e.g., from the chromosome to a plasmid or between plasmids) as well as those that enable intercellular DNA mobility.

Insertion sequences (IS) and transposons (Tn) are discrete DNA segments that areable to move themselves (and associated resistance genes) almost randomly to newlocations in the same or different DNA molecules within a single cell. Other elements, such as integrons (In), use site-specific recombination to move resistance genes between defined sites. As these types of MGE are often present in multiple copies indifferent locations in a genome, they can also facilitate homologous recombination(exchange of sequences between identical or related segments). Intercellular mechanisms of genetic exchange include conjugation/mobilization (mediated by plasmidsand integrative conjugative elements [ICE]), transduction (mediated by bacteriophages), and transformation (uptake of extracellular DNA). Interactions between thevarious types of MGE underpin the rapid evolution of diverse multi resistant pathogens in the face of antimicrobial chemotherapy. Primarily the most important and/ or topical elements in Gram-negative and Gram-positive bacterial species of particular concern clinically, namely, Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter spp. (the so-called ESKAPE group) (Rice LB., 2008) as well as Escherichia coli (giving the ESKAPEE group) (Llaca-Díaz J.M. et al.,2012); nonetheless, many of the MGE types described are of course broadly relevant to many other bacterial taxa.

Introduction

Gender is a topic that cuts across all subjects and should be considered. The generational dimensions of rural and agricultural growth, whether we’re talking about kids, teenagers, or the elderly, have also grown in importance in recent years. Therefore, it is not surprising that a specific focus should be given on the issues of gender and youth and their relevance to the growth of agriculture. However, it is our custom to start with a few points to lay a foundation of thoughts. Nations Like India where majority of farmers practise subsistence agriculture, rural development is the cornerstone of agricultural development. According to the type of the problem in each country, an assessment of the present global response to the food crisis has indicated that various strategies are being implemented with varying degrees of success and failure. Different tactics are being used to shield the underprivileged from the rise in price shocks. Investment in the agricultural sector is consequently important for rural development and a rise in agricultural output. The contribution of women is also essential to the overall success of initiatives aimed at rural development to boost agricultural production in India. In sub-Saharan Africa, Women engage in more agricultural work than men do and supply the bulk of the labour for a variety of agricultural tasks. Women make up around 90% of the workers directly involved in producing arable crops (Ogunlela and Aisha, 2009). Therefore, rural development will occur when different pertinent institutions are given attention, including cooperative societies, the system of land tenure, banks and credit, the creation of sustainable local governments, educational institutions, medical institutions, and agricultural marketing outlets.

Introduction

Krishi Vigyan Kendras (KVKs) have marked their presence across India by executing various scientific as well as institutional reforms for the agrarian mass of our country. Right from its beginning in 1970s, farmers were actively trained for adopting different innovative tools and methods and were also provided with proper assistance in implementing them. The farmers were adapted to technical know-how of an introduced technology and produced significant results in the real f ield conditions.

KVKs provided proper training programmes on need-based curriculum in order to cater to the local and regional needs. This has also led to need assessment of various training needs and efficacies to make improvement in policies and future interventions. KVK can be instrumental in nurturing the process of gender empowerment by inviting and involving the farm women in the process of technological adaptation, adoption and socialization. There are methodological innovations as to how we can involve the farm women by employing and applying gender-sensitive KVK technologies as suitable for their job environment and climate. Especially in areas of value addition, rural crafts, women crafts, f ishery, horticulture and micro-finance, their roles are becoming more prominent and decisive. This is positive achievement in making them free from gender discrimination and impoverishment.

The knowledge score gained by respondents after training was more satisfactory in all aspects (58.33% had medium and 48.67% had high level of knowledge). The socio-economic factors of the participants viz. Education level played a significant positive role on the knowledge gain of the participants. (Upamanya et.al., 2020) Most of the farmers, i.e., 66.67 per cent with theoretical knowledge suggested that more field visits can be arranged, 63.33 per cent of the respondents suggested the training should be conducted in their own villages because the farm women cannot able to come to KVK by leaving their children and their regular household work and around sixty per cent (60.83 per cent) of the respondents suggested that organizing continuous and frequent training programmes for effective participation and retention of knowledge. (Chakkaravarthy and Balakrishnan, 2020)

In a country like India where the economy is dominant by agriculture and its allied sectors, nearly 75% of women are engaged in agriculture in comparison with their male counterparts. Among rural female workers, 50% comprises of agricultural laborer and 37% are cultivators. Not only this, around 70% of total farm work is performed by women folk. Majority of agricultural works are done by women farmers (FAO, 2011) and thus empowering them will have far-reaching effect on agricultural development. They usually operate multiple livelihood f ields, including farming, animal husbandry, and marketing along with doing the household chores and are closely involved in social issues. Among these activities when we look specifically into the agricultural tasks, it is very clear that approximately 70–80% of women are participating in all agriculture activities from raising seedlings, weeding, harvesting and, processing and value addition activities and sometimes their involvement extends to marketing their product. To compete in this fast-growing industry with others, the rural women need to be up-to-date with new technologies to foster the reach of innovations to the farm women. Training is one of the most important means by which farmers and rural women can upgrade their professional and technical skillset. This is an essential component in the area of agriculture where technology is changing day by day and the knowledge of the farming community including women needs to be upgraded at a comparatively quicker pace.

1. Introduction

Over the years, Agriculture Extension has been at the fore front within the delivery of adequate data to the farming community not just for increasing productivity however additionally to reinforce their standard of living. Keeping in-sight of the demand for agricultural growth, evolutionary modifications had been made in transfer of technology to succeed in the farming community effectively. The Information and Communication Technology (ICT) is one among the required counterparts which made the agriculture extension more realistic and quite interesting.

Developing nations like India are though capable to get self-sufficiency in food production after green revolution however they’re in risk to keep this self sufficiency as they are possibly to face food shortage in near future due to rapid population growth. Thus, the demand of continuous increasing population is often fulfilled with the assistance of ICT as a tool of revamping extension network of the country. ICT is an emerging tool for development of farming communities.

Information and communication technologies have unique feature that provide opportunities to harness them in ways which are extraordinary from traditional media. ICT provides two-way communication between rural communities and development organizations. ICTs also improves the capacity to look for information and increase the number of information available, provide quality information, reduces uncertainty and enhance market participation.

Introduction

The concept of communication for development emerged with the Modernization theory, which developed its roots after World War II. Wilbur Schramm and Daniel Lerner, the two major proponents of this theory opined that the major obstacle to development was the psychology of the undeveloped citizens. The communication models under modernization paradigm observed communication process as the transfer of message from sender to receiver (Lasswell, 1948). It was found that communication theories like two step-flow, diffusion theory, or the early extension approaches were quite harmonious with the top-down modernization theory. After the Modernization paradigm, an another theory of communication for development emerged named as Dependency theory. Dependency theorist like Jean Servaes (1996) criticized the broadcasting and other mass-media systems as they tended to support modernization and were anti-development; also they were inclined to promote the political agenda. Solution to underdevelopment of third world countries require major changes in media structure that were dominated by commercial principles & foreign interests into media structures which are self-reliant and community oriented (Servaes, 2002). In 1970s scholars such as Paulo Freire and Nora C. Quebral started pleading in favour of bottom up development theories which led to evolution of a new development paradigm called the multiplicity paradigm. This paradigm conceptualised the basic idea that development is integral, multidimensional and dialectic process which can differ from one society to another (Okigbo and Eribo, 2004). Multiplicity paradigm led to emergence of a new form of communication called participatory communication.

Introduction

India is an agriculture-based country and it contributes most to the economy of the country. Different types of crops are cultivated in a wide range in different ecological regions based on different seasons. So, crop residue is also generated in an extended way by cultivation (Devi et. al 2017). Crop residue is the left over part of the crop after harvesting. In India, crop residue generates around 600 Mt and from which cereals are 70%, fibres 13%, oilseeds 6%, pulses 3%, sugarcane 2%, and others 6% (Jain et al., 2014). Corn production has increased more than 15 times from 1950-51 to 2016-2017. Rice, wheat, millet, barley, and maize are important cereal crops in Uttar Pradesh (Roy and Ahmad, 2015). Traditionally, Crop residue was used as cattle feed, animal bedding, cooking fuel, organic manure, etc. and some residues were used in making handicraft products by rural women. but still, a huge amount of residue is left without management and farmers have no option left except to burn it. About 90 to 140 Mt of crop residue burning in the field or households as fuels (Jain et al., 2014). In the process of harvesting and threshing, residues are left behind in the f ield. Farmers need to clear their fields early for the planting of the next crop so they do have not enough time and it is tough to clear the field at that time. Therefore, the farmers opt for the burning of residue in harvested fields due to a lack of access to user-friendly, cost- and time-effective options. The burning of crop residue creates many issues and effects on the environment and health badly. In a report of NAAS in 2017, it was estimated that in November 2016 at the period of rice residue burning, the NASA satellite images showed the intensity of rice residue burning in Punjab, Haryana, Western Uttar Pradesh, and Uttarakhand was very high. It is doing an additional job of increasing air pollution with vehicles, chimneys, industries, etc. Crop residues release many gases by burning them and these gases are contributing to global warming.

Introduction

Self Help Group is a voluntary and self managed group of poor people, who come together to promote savings among themselves and pool savings for activities benefiting either individuals or communities economically. Empowerment of women has now become a key issue in the Government’s Five year plans by organizing women into Self Help Groups to make the beginning of a major process of empowering women. 320 million people, out of our 1.1 billion, are steeped in abject poverty and due to their asset lessens it is difficult for them to access any kind of aid from banking / financial institutions and this state of the hopelessness and the constraints of an ineffective credit delivery system can be transcended by enhancing the self esteem and raising the feeling of human self worth. The SHGs approach is a reshaping initiative that enhances the livelihoods and ensures sustainability by enabling poor families to access effective economical and social development leading to empowerment.

In Tripura SHG’s has been introduced in the year 1999.The main objectives of this programme by mutual beneficial of social and economic activities through women mobilization. SHG’s are a way to involve rural women and men actively in the development process by means of increased income Agricultural situation of WTD differs to some extent from the other districts in regard to topography, soil, extent of rain-fall, variation in temperature and humidity which has resulted in difference in cropping pattern also from that of the other three districts. People mainly practice rice and vegetables cultivation. The plain land people also were satisfied to grow single crop preferably paddy without having any knowledge and experience of improved cultivation for growing multiple crops. Animal husbandry is another sector contributing to the economy of WTD. Cattle and poultry are the main livestock wealth of the district. (DRDA office, Agartala, 2010). Many Government and non-government organization now have come forward for helping poor communities and to energize their capacity in development activities of which Self Help Group (SHGs) is thought as the best means for improving their position in the society.

Introduction

Rising temperature, decreasing precipitation, increased frequency in drought and flooding, etc. is making us realize climate change is not some cooked up story. Still there are people who believes climate change is not real. By definition, Climate change is a long-term shift in global or regional climate patterns. This will affect the life of people in many forms: health, food, water, etc. (Table 1). Agriculture is a highly vulnerable field to such weather and climate changes, they can have significant direct and indirect impacts on farm productivity and profitability. Climate change will have adverse effect on crop physiology, growth and chemistry and thus it will cause negative impact on agricultural production. Because of the variation in climate, moisture availability may change, which limits vegetation activity/plant growth, increase in drought/ heat/flooding will the crop growth and yield. Elevated CO2 does not have a profound effect on C4 plants. On the contrary, tissue nitrogen concentrations are higher for C3 species under increased CO2 . Intergovernmental Panel on Climate Change (IPCC) estimates that climate change and elevated CO2 is expected to increase competitiveness of invasive weed. IPCC also estimates that with 1°C rise in global temperature, 5 to 10 per cent yield reduction of major food and cash crops (Pachauri et al., 2014).

Introduction

Climate change is widely acknowledged as the most significant contemporary challenge facing humanity. According to a recent report from the Intergovernmental Panel on Climate Change (IPCC, 2022), the situation has deteriorated further, with 3.3 billion people worldwide highly susceptible to climate change. Current unsustainable development practices are escalating the exposure of ecosystems and populations to climate-related risks. Human activities and their impact on the climate and environment are leading to unprecedented extinctions of animals and plants, resulting in a loss of biodiversity and posing a threat to life on Earth. The diversity of microorganisms is fundamental to maintaining a healthy global ecosystem, as the microbial world serves as the life support system of the biosphere. Although the influence of human activities on microorganisms is less conspicuous and less well understood, a significant concern is that changes in microbial biodiversity and functions will impact the resilience of other organisms, affecting their ability to adapt to climate change. Microorganisms play crucial roles in carbon and nutrient cycling, as well as in the health of animals (including humans), plants, agriculture, and the global food web. Microorganisms inhabit all environments on Earth occupied by larger organisms and are the exclusive life forms in certain environments such as the deep subsurface and extreme habitats. Dating back to the origin of life on Earth at least 3.8 billion years ago, microorganisms are likely to persist well beyond any future extinction events. Despite their vital role in regulating climate change, microorganisms are seldom the focal point of climate change studies and are typically overlooked in policy development. The challenge lies in understanding their intricate role in the ecosystem due to their vast diversity and varied responses to environmental changes.

Introduction

Climate change may advance more rapidly than anticipated, introducing novel environmental conditions for cultivating horticultural crops. The rise in atmospheric CO2 levels from non-renewable energy sources combustion drives global average temperatures, altering weather patterns worldwide with regional variations (Stocker et al., 2013). Currently, certain regions are already experiencing the effects of extreme weather events such as heat waves or frost, while prolonged droughts pose a growing threat to global food security elsewhere. Climate changes may yield both positive and negative outcomes, but they will undoubtedly alter production conditions and product quality (Kaufmann and Blanke, 2017).

Elevated temperatures can enhance the ability of air to hold water vapor, leading to increased water demand. This process can elevate evapotranspiration rates, potentially depleting soil water reserves and causing water stress in plants during dry periods. Fruit production is particularly vulnerable to water stress, especially in regions where trees lack irrigation. Numerous studies indicate that water stress diminishes crop yields and hastens fruit ripening (Henson, 2008).

3.1 Introduction

Groundwater constitutes about 89% of the total fresh water resources in the planet. But in recent years, due to over exploitation of ground water and erratic nature of monsoon, there has been depletion of ground water across the world. Depletion of ground water has reached to the extent that it is virtually impossible to get the water table back. Even though there is a possibility of recharge of water from the other areas, the process is very slow and may take one year to replenish one meter. In view of this management of ground water has become one of the most significant issues in recent times. Added to it, there are also environmental problems such as aqua for mining, salt water intrusion, stream base flow reduction etc. For several reasons the efficient management of ground water resources through market mechanism has become difficult. Against this context the present article attempts to analyze the need for sustainable ground water management in India. The article also briefly discusses the concept of sustainable ground water management, factors affecting ground water availability, different approaches towards developing and using available ground water without adversely affecting the hydro geological balance. Further, the paper highlights strategies for sustainable groundwater management, including development of aquifers, rainwater harvesting and artificial recharge methods. The article offers some relevant policy recommendations for sustainable groundwater management in India.

Cheese is made from milk, with the addition of cream, buttermilk, and/or whey. This basic raw material is also called cheese milk. Cheese consists mainly of casein (the major protein of milk), other milk proteins, fat, other milk components, and a certain percentage of water, which is bound. Proteins are precipitated by enzymes and/or acidification as well as heat and are separated by suitable processes from the aqueous phase. (whey, serum). Cheese is most often molded, pressed, and salted and has fungal and bacterial culture additions. colorants, herbs, spices, and other non-dairy ingredients are also added to the cheese. It is consumed either fresh or at different stages of ripening.

Worldwide, there are more than 2000 types of cheese, sometimes made by very different manufacturing processes. A classification can be based on several aspects and is done in different countries according to different criteria. A general classification can be made for three major groups:

a. Rennet or natural cheese: manufactured straight from milk by using proteolytic enzymes (rennet) and acid, with a more or less pronounced ripening process.

b. Fresh cheese or non-ripened Cheese: Quarg, fresh cheese, and white cheese are examples. Its manufacturing process is similar to that of rennet cheese manufacturing, but it has a high degree of acidity and is not subjected to a proteolytic ripening process.

c. Long-life cheese (processed cheese): it is more often made from rennet cheese and is textured by thermal treatment and made shelf-stable.

Clinical Symptoms

• Anchor worms can be seen with the naked eye

• Frequent rubbing or “flashing”

• Localised redness

• Inflammation on the body of the fish

• Tiny white-green or red worms in wounds

• Breathing difficulties

Spontaneous contractions of the uterus are controlled and coordinated for various reproductive functions. The non-pregnant uterus facilitates ova and sperm transport, provides adequate embryo placement for implantation, and contributes to the expulsion of menstrual debris through increased contractility, or periods of relative quiescence (Hutchings et al., 2009). Uterine dysmotility has been implicated in the pathogenesis of certain infertilities, implantation failure, endometriosis, dysmenorrhea, and abnormal menstrual events (Kunz and Leyendecker, 2002; Aguilar and Mitchell, 2010). Although these conditions may not contribute to mortality but can significantly affect patient’s reproductive health, and considerably alter their quality of life (Jones et al., 2004; Weissman et al., 2004; Chachamovich et al., 2010). Dysmenorrhoea refers to the occurrence of painful cramps in the lower abdominal region during menstruation and is one of the unresolved gynecological disorders in adolescent girls and women of reproductive age (Wang et al., 2004; Harel, 2008). This condition is mainly characterized by cramping pain in the lower abdomen immediately before or during menstruation, which does affect the quality of their life and work (Davis and Westhoff, 2001).

Introduction

Minerals are present in all body tissues and fluids to carry out the physicochemical processes of life; both in animals and human. It is broadly classified into two categories: (1) macro and (ii) micro or trace elements. The macro elements include calcium, phosphorus, potassium, magnesium, sulfur, sodium and chloride, while elements such as iron, copper, cobalt, iodine, zinc, manganese, molybdenum, selenium and chromium come under micro elements. Animals need large amounts of calcium for construction and maintenance of bone and normal function of nerves and muscles. Phosphorus is a vital constituent of adenosine triphosphate (ATP) and nucleic acid and is also essential for acid-base balance, bone and tooth formation. Iron is an important component of the cytochromes for carrying out cellular respiration in addition to its vital role in red blood cells. Magnesium, copper, selenium, zinc, iron, manganese and molybdenum are important co-factors found in the structure of certain enzymes and are indispensable in numerous biochemical pathways. Animals need iodine to make thyroid hormones. Sodium, potassium and chlorine are important in the maintenance of osmotic balance between cells and the interstitial fluid. Excessive intake of some minerals can upset homeostatic balance and cause toxic side effects.

9.1 Success Stories from Around the World

Sustainable aquaculture practices are essential for ensuring the long-term viability of the aquaculture industry while protecting the environment, supporting economic development, and enhancing social welfare. This article highlights several success stories from around the world that exemplify innovative and sustainable aquaculture practices. These case studies demonstrate the diverse approaches taken to achieve sustainability in different regions and contexts.

1. Integrated Multi-Trophic Aquaculture (IMTA) in Canada

Location: Bay of Fundy, Canada

Species: Atlantic salmon, blue mussels, kelp

Approach: Integrated Multi-Trophic Aquaculture (IMTA) is a practice where different species are farmed together in a way that mimics natural ecosystems. In the Bay of Fundy, Canada, salmon, mussels, and kelp are cultivated in proximity, creating a balanced system. The salmon are fed traditional aquaculture diets, and their waste provides nutrients for the mussels and kelp.

American Ecologist Whittaker (1969) proposed the five kingdom system of classification. In his ‘Five Kingdom System’, he added three more kingdoms in to Linnean model of two kingdom system. These were: Monera, Protista and Fungi. Whittaker succeeded to overcome the difficulties as well as demerits of two, three and four kingdom systems and to represent the living organisms according to the evolutionary relationships among themselves. He also defined the kingdoms by a number of special characteristics such as whether the organisms possessed a true nucleus or not. Whittaker’s five kingdom system of classification is based on (a) mode of nutrition (b) cell structure and complexity (c) phylogenetic relationship (d) body organization and (e) reproduction.

The large branches within the Animal Kingdom evolutionary tree are ‘phyla’ (the singular being ‘phylum’). ‘Animal phyla’ outlines thirty three phyla, although there are still disputes and disagreements concerning how many phyla are needed to classify the less well-known species. The most easily recognised are Porifera, Cnidaria, Arthropoda, Nematoda, Annelida, Mollusca, Platyhelminthes, Echinodermata, and Chordata. Animal phyla each comprise a branch of the evolutionary tree and these branches are always connected to other branches.

Introduction

• At present, horticulture is recognized as a potential sector to enhance agricultural production, improve house hold nutritional security and income generation through diversification and employment, value addition and export.

• Inspite of the enormous success achieved in horticulture sector, several constraints still exist.

• Besides new emerging challenges, poor productivity per unit area continues to be a concern in most of the horticultural crops with climate change impacting the productivity further.

3.1 Role of root stock in fruit crops

• The role of rootstocks and its use in different fruit crops has significant impact on fruit crop production by influencing canopy architecture, nutritional uptake, flowering, yield and fruit quality.

• Besides, it can also confront biotic and abiotic stresses such as soil pathogens, thermal stress, salinity and nutritional stress.

• Due to limited availability of arable land and high market demand for fruit crops, they are frequently cultivated under unfavorable soil and environmental conditions like thermal stress, drought, flooding, salinity and contamination of organic pollutants.

• One way to substantiate or reduce these losses in production would be the use of appropriate rootstocks, which are capable of reducing the effect of external stresses on the scion.

• Rootstocks have a primary role in determining orchard efficiency.

• They are responsible for water and mineral uptake and provide anchorage for the tree.

10.1 What is nutrient management?

• Nutrient management is an important component in orchard management for high efficiency and high fruit quality. Fruit trees are perennial woody plants which can store nutrients and then release them for growth.

• Therefore, the nutrient uptake of fruit trees includes the total nutrients of the fruits, leaves, new branches, and time increments of storage. Nutrient uptake is different under different yield levels. For example, the N uptake of apple trees was 100–120, 110– 130,120–140, and 130 150kg/ha under yield levels of 30, 45, 60, and 75t/ha, respectively.

• Basal fertilization is considered to be important for high-quality fruit production by providing nutrients for tree growth and also improving soil structure which promotes better root development. It is usually recommended and immediately applied during the dormant season up to autumn, after fruit harvest.

• Top dressing applications are usually chemical fertilizers which are applied two to four times before bud break or prior to or after blooming and at the fruit enlargement stage, depending on the requirements of each type of fruit tree.

• Using this INM method, the total nutrient demand is calculated according to target fruit yield level and NPK fertilizers are recommended based on soil fertility index (High, Moderate, and Low soil fertility) and nutrient demand with different stages. For moderate apply trees, most of N fertilizer is applied in autumn after picking to add N storage and renew tree vigor, and most of the P fertilizer is applied in spring with flowing stage to improve flower bud quality, and most of the K fertilizer is applied in summer fruiting period to improve fruit quality. Management of high yielding fruits using suitable pruning, and irrigation, are combined in this INM

INTRODUCTION

Biodiversity can be useful as an ecosystem indicator for conservation and monitoring, through continuous assessment of its main properties including stability, primary productivity, exploitation tolerance and even global environmental changes (Douglas et al., 2012). Crustaceans are found one of the most morphologically diverse taxonomic groups on the planet (Martin and Davis, 2001). Among them, decapods are the most studied taxon, mainly on account of the commercial interest of some species and their great diversity (Isarch and Munoz, 2015). Decapods are chiefly composed of marine species that live in waters depths ranging from shallow to deeper than 5000 m. Isarch and Munoz (2015) described the importance of this group lies in several factors such as the great biomass they represent, their significant role in marine food webs and the commercial interest of many decapod species. Order Decapoda comprises the commercially important shrimps, crabs and lobsters. Out of 649 species of marine crabs so far recorded from Indian waters, only 12 species of edible crabs namely Portunus sanguinolentus, P. plagicus, Charybdis feriatus, C. lucifera, C. annulata, C. natator, Scylla serrata, S. tranquebarica, Matuta lunaris, Sesarma tetragonum and Varuna litterata, which inhabit the coastal waters and adjoining brackishwater environments, support commercial fisheries (Menon and Pillai, 1996). However substantial quantities of crabs are landed every year as by-catches of shrimp trawlers and indigenous fishing units throughout the county.

India represents one of the major contributors to the world production of marine crustaceans. Shrimps constitute as the main seafood export industry for the major foreign exchange earner as well as a source of livelihood for millions of fish workers. As shrimps are targeted for fishing, information on the present status of the fishery is critical for implementation of proper management. Some of the important penaeid shrimps that support commercial fisheries along the Indian seas are Fenneropenaeus indicus, P.semisulcatus P.monodon, P.merguiensis, P.japonicus, P.penicillatus, Metapenaeus dobsoni, M.monoceros, M. affinis, M. kutchensis , M. brevicornis, Parapenaeopsis stylifera, P.hardwickii, P.sculptilis, P.maxillipedo, P.uncta, Trachypenaeus curvirostris, Metapenaeopsis stridulans, Parapenaeus longipes, Solenocera crassicornis and S.choprai (Mohan Joseph and Jayaprakash, 2003). Rajkumar et al. (2015) carried out molecular identification of shrimp species, Penaeus semisulcatus, Metapenaeus dobsoni, Metapenaeus brevicornis, Fenneropenaeus indicus, Parapenaeopsis stylifera and Solenocera crassicornis from Tamil Nadu, India.

INTRODUCTION

An expanding aquaculture industry that offers high incomes and job opportunities to people worldwide is ornamental fish farming. With over 2 billion live ornamental fish traded globally, the ornamental fish trade has become a very lucrative sector (Das & Biswas, 2016; Katia, 2001) with global net worth of more than 20 billion USD. According to Saxena (1994), the most significant factor influencing an ornamental fish's market value is its vibrant body colouration. Fish are incapable to synthesize carotenoids De novo (Goodwin 1951),and rely on dietary carotenoids for its body pigmentation (Hata and Hata, 1973). So, there is hence a direct correlation between pigmentation and dietary carotenoids(Halten et al., 1995). Aquatic animals' skin, meat, shell, and exoskeleton are coloured red, orange, and yellow due to a class of naturally occurring lipid-soluble organic pigments called carotenoids (Pailanet al., 2012). Fish skin and muscle colour regulation is significantly influenced by dietary carotenoids (Ahilan et al., 2008). The freshwater ornamental fish industry has encountered the issue of fadingfish body colouration, particularly in cases where the fish are reared in captivity for extended periods of time and subjected to rigorous cultivation conditions (Das and Biswas, 2016). According to Das and Biswas (2016), an ornamental fish's food should generally be nutritionally balanced, appetizing, resistant to crumbling, water stable, buoyant, and enhance or retain the fish coloration.

The phenomena of coloration in fish are quite significant and have a direct impact on its aesthetic value. If pigment-enriched feed can be prepared and used to increase coloration, the fish will undoubtedly have better quality and a cheaper price tag. Detailed research on colour enrichment in native ornamental fish using formulated feed is lacking (Das and Biswas, 2016). For the purpose of colour enrichment in fish, native plant sources have been used. Choubert (1979), Boonyaratpalin and Phromkunthong (1986), and Alagappan et al. (2004), utilized spirulina as a source of carotenoid colours for fancy carp and rainbow trout. Enhancement of pigmentation of Cyprinus carpio and Carassius auratus with microalgal biomass supplementation has demonstrated that Chlorella vulgaris is just as effective as synthetic colours (Gouveia et al., 2003). Alagappan et al. (2004) observed increased body pigmentation in Trichogaster trichopterus using Spirulina sp. algae as a source of carotenoid pigment. The body pigmentation of goldfish (Carassius auratus L.), red swordtail (Xiphophorus helleri), and tiger barb (Puntius tetrazona) was enhanced by feeding with marigold petal diet (Boonyarapatin and Lovell, 1977; Ezhil et al., 2008; Alma et al., 2013). Using natural sources of carotenoid pigments to improve the colour of ornamental fish is a cost-effective and ecofriendly solution. Due to the aforementioned information, the current study was carried out to assess how dietary natural carotenoids from source such broccoli (Brassica oleracea var. italica) effects the development and coloration of Blue Gourami, Trichogaster trichopterus, one of the important ornamental fishes with high market value.

INTRODUCTION

Wheeler bearers commonly referred to as ‘Rotifers ‘are significantly they are often taken as reliable indicators of mesotrophic characteristics in the lake ecosystems (Gannon and Stemberger, 1978). Because of their wide tolerances to varied dissolved oxygen levels and temperature distributions, they are even found to inhabit the deeper waters of aquatic ecosystems (Esparcia et al., 1989). They belong to the Kingdom Animalia, Subkingdom Eumetazoa, Phylum Rotifera (Cuvier, 1798) having three classes Monogononta, Digononta and Seisonidea (Pennak 1953). In other words these wheel animalcules named, because of the presence of their corona, which is composed of several ciliated tufts around their mouth region. This ciliated tuft helps in locomotion and resembles a wheel. These create a current that sweeps food into the mouth, where it is chewed up by a characteristic pharynx (called the mastax) containing a tiny, calcified, jaw-like structure called the trophi. The cilia functions to pull the animal, when unattached, through the water. Most free-living forms have pair of posterior toes to anchor themselves while feeding. Rotifers are bilaterally symmetrical found in various shapes. There is a well-developed cuticle, thick and rigid, providing a box-like shape, or flexible, giving the animal a worm like shape; such rotifers are respectively called loricate and illoricate.

Habitats of Rotifers are relatively easy to find. Many live in ponds, moist soil, or any stagnant water. Rotifers can be free swimming or sessile. Rotifers are mostly omnivorous and some have been observed to be cannibalistic. They normally eat algae or decomposing organic material. As they are a major food source for Cladoceran , Copepodans , juvenile fishes (fry) and fishes, therefore , an important food link of water ecosystem (Arora and Mehra 2003). Presence of abundant Rotifers in freshwaters determines them to be one of the main groups of zooplankton in limnological studies. They are permanently and obligatorily connected to aquatic habitats in all active stages and only their resting stages are drought-resistant (Chopra et al 2012). Various researchers have conducted pioneer study on the diversity and habitat of rotifers such as Anderson 1889; Sharma 1987; Sharma 1998a; Gilbert and Schreiber 1998; Arora and Mehra 2003; George et al. 2011; Tyor and Chawala 2012. However such studies on Madhuganga dam water has not been conducted, hence for assessment of Madhuganga Lentic water has been conducted for the seasonal variation in diversity and density of rotifers.

INTRODUCTION

The expansion of aquaculture, a vital source of income for a large portion of the global population (Salam et al., 2014), has created an unforeseen challenge: increased competition for land use with traditional agriculture. This land squeeze is further intensified by a multitude of factors. Shrinking arable land due to urbanization and desertification, coupled with the relentless growth of the human population, puts immense strain on existing agricultural resources. Man-made environmental pollution from industrial waste and agricultural runoff, along with the far-reaching effects of climate change, add another layer of complexity. These combined pressures necessitate a paradigm shift towards innovative and sustainable agricultural practices.

One promising solution gaining traction is aquaponics, a system designed to cultivate plants and aquatic animals together in a carefully balanced, recirculating environment (Salam et al., 2014). This approach leverages a symbiotic relationship between fish and plants. Fish waste, rich in nitrogenous compounds, acts as a natural fertilizer for the plants growing in the system. These plants, in turn, function as biofilters, removing excess nutrients and purifying the water for the fish. In essence, aquaponics integrates two established agricultural techniques: intensive aquaculture, the practice of raising fish in controlled tank environments, and hydroponics, the cultivation of plants without soil (FAO, 2012). The aquaculture component of aquaponics utilizes eco-friendly, indoor recirculating systems that enable meticulous control over water quality and temperature year-round. This controlled environment offers significant advantages over traditional methods, minimizing dependence on external factors like weather patterns.

INTRODUCTION

Integrated farming is an innovative approach towards increased fish production. In integrated fish farming two or more commodities are framed together on a common infra-structural base with the objective of optimizing use of available resources. It is based on the concept that “there are no wastes and waste is only a misplaced resource, which can become a valuable material for another product”. There are several advantages of integrated farming system viz. increased productivity, greater income, improved cash flow, fuller employment, a better diet for the farmer’s family and less biological and economic risk (Pillay, 1990). On the other side, there is the disadvantage that the integrated system is more complex, with a need for more knowledge and better management, since the failure of one system could adversely affect other system (Singh et al., 2014). In integrated farming system, animal manure is shed directly into a fish pond as fertilizer and supports the growth of natural fish food organisms. The fish not only utilize spilled animal feed, but also directly feed on fresh animal excreta which is partially digested and is rich in nutrients. Surplus excreta support the rich growth of planktonic fauna. Fertilizers and supplementary feed are not used, resulting in a drastic cost reduction. These farming systems are relatively confined units with little exchange of water. Manure from livestock which indirectly trigger the growth of mainly photosynthetic organisms resulting in the production high yields fish with low input and limit the dependency on supplementary feed (Saikia et al., 2020 and Sharma et al., 1979; 1998). Ugwumba et al. (2010) suggested that the higher the number of viable enterprises integrated into an agricultural system the higher the expected profit. Integrated culture system is quite compatible with the earthen pond culture and relevant to benefit the rural poor (Misra et al, 2016, Vohra et al., 2012).

As per 20th Livestock Census (2019), Punjab has 1.3% share of India’s total livestock. The share of buffaloes was largest (57.4%) in total livestock population, followed by cross-breed cattle and indigenous cattle. The state of Punjab has about 70.60 lakh livestock in total, comprising of 25.41 lakh cattle, 40.16 lakh buffaloes, 3.48 lakh goats, 0.85 lakh sheep, 0.53 lakh pigs, 0.15 lakh horses and ponies, 1644 mules, 471 donkeys and 170 camels. The share of crossbred cattle increased to 29.3% in 2019 compared to 25.4% in 2012 which signifies that the farmers in the state are resorting to high yielding animals for increasing the milk production. These efforts have led to the highest per capita availability of milk in Punjab which stands at 1271 grams per day compared to national average of 444 grams per day (2021-22), although the share of Punjab in country’s milk production is 6.37%. Punjab is sixth largest producer of milk in India, with production of 14.76 million tonnes (t)/year.

Climate change has emerged as one of the most pressing global challenges of our time, with far-reaching consequences for ecosystems, economies, and societies. This has led to the higher temperatures, changing precipitation patterns, sea level rise and growing frequency and intensity of extreme weather events such as drought, floods, extreme heat and cyclones resulting in disruption of food supply chains. The most critical domains that impact environmental sustainability includes energy, transport, food, waste and water , although there are disparities in the consumption patten of high-income and low income countries. Apart from the food domain (33% of total GHG emissions), meat from ruminants and dairy products constitute the major proportion of carbon footprint. Although only 18% of calories are obtained from meat and dairy products, but they together account for 60% of agriculture’s greenhouse gas emissions and occupy 83% of the world’s arable land. With 18% of anthropogenic greenhouse gas (GHG) emissions, the livestock sector has been identified as one of the primary causes of climate change and the dairysector accounts for around 3.0- 5.1% of the total GHG emissions globally.

Intensive farming operations are particularly vulnerable to an increased risk of biohazards due to their densely populated livestock and close confinement. This increased animal density creates an environment where diseases can spread rapidly if not adequately managed. To mitigate these risks and safeguard the health and productivity of dairy herds, stringent farm biosecurity measures are essential. Farm biosecurity, a comprehensive framework of preventive measures and protocols, has emerged as a pivotal strategy in ensuring animal health and curbing the rise of antimicrobial resistance (AMR). By prioritizing biosecurity, dairy farmers can maintain a healthy and disease-free environment for their animals, ultimately ensuring the quality and safety of dairy products while promoting sustainable and responsible farming practices. In recent years, the interconnected challenges of animal health and AMR have prompted a re-evaluation of agricultural practices and disease management strategies.

What is Farm Biosecurity?

Farm biosecurity refers to the set of practices and measures employed to prevent the introduction and spread of infectious diseases within animal production systems. It encompasses a wide array of strategies, ranging from physical barriers and hygiene protocols to monitoring and surveillance programs. The core principle of farm biosecurity is to mitigate the risk of disease incursions by minimizing the exposure of animals to pathogens, thereby preventing outbreaks and reducing the need for antimicrobial interventions. This strategic approach can be broadly categorized into ‘external farm biosecurity’ and ‘internal farm biosecurity’, each addressing distinct aspects of disease prevention within the farm environment.

Ice bank cooling: Storing of fruit and vegetable in storage chamber with positive ventilation and system countries where ice formation is allowed during night time (as electricity cost of night is less as compared to the day time). Melting of ice occurs during day time and with proper air circulation by means of ventilation process, approximately 0.5 10C temperature with 90% RH in the chamber is maintained. Ice Bank Cooler / Air forced cooler leads to desiccation of the produce (Plate 359). So use forced air high humidity cooler and these are known as Ice Bank Cooler. Ice bank coolers are useful for strawberry.

Ice cream: Ice cream may be define as frozen dairy product made by suitable blending and processing of cream and other milk products together with sugar and flavour.

Ice cream cone: A thin crisp edible cone for holding ice cream and filled with ice cream.

Ice point: It is the temperature of equilibrium between ice and water under normal atmospheric pressure (Plate 360).

Ichthylogy: It is the branch of the zoology that deals with the study of fishes (Pisces).

Icicle: It is small tapering piece of the ice formed by freezing of dropping water (Plate 361).

Introduction

Agriculture plays a vital role in India’s economy 54.6 per cent of the total workforce was engaged in agricultural and allied sector activities (Census 2011). Agriculture sector is estimated to grow 3.9 per cent in 2021-22 on top of 3.6 per cent and 4.3 per cent, respectively in the previous two years. Agriculture sector accounts for 18.8 per cent of GVA in 2021-22 (Economic Survey 2021-22). The agricultural industry has experienced numerous issues, such as a shortage of food, because of the high cost of production and low yield per hectare. In certain situations, it has also grown more difficult to provide for their fundamental requirements, such as clothes and shelter. By boosting their income and purchasing power through agricultural inputs like fertilizers, insecticides, agricultural equipment, etc., agricultural marketers in India play a crucial role in the rural areas. The India is world's biggest producer of agricultural goods. Food grain output grew significantly during the 1960s and 1970s, with wheat and rice production rising. Compared to farmers in Western nations, farmers in countries like India, China, and Japan are more prone to growing cash crops.

The Minimum Support Price (MSP) system is a critical component of agricultural policy in many countries, aimed at ensuring farmers receive a fair and stable income for their produce. However, the relationship between MSP and market forces is complex, as MSP policies can impact agricultural markets, farmer livelihoods, government budgets, and food security. This chapter explores the interplay between MSP and market forces, examining the challenges, benefits, and implications of MSP policies in the context of agricultural markets.

Introduction

The field of public finance is a critical aspect of economic governance that delves into how governments manage their revenue, expenditures, and debt to fulfill societal needs and ensure economic stability. Public finance encompasses the financial activities of governments at various levels, including national, state, and local, focusing on the income and expenditure of public authorities and the underlying principles guiding these financial transactions.

Significance of Public Finance

• Role in Society: Public finance is a branch of public policy and economics concerned with how governments raise funds, allocate resources, and address economic and social needs.

• Government Functions: Governments provide public goods and services like infrastructure, defense, education, and social welfare programs that are essential for societal well-being.

• Market Correction: Public finance enables governments to address market failures by providing public goods that individuals or businesses would not produce efficiently on their own.

• Income Redistribution: Through programs like social security and welfare, public finance helps moderate income disparities by supporting those in need.

Considered as one of the leading members of the family Bromeliaceae, pineapple is one of the most extensively consumed fruits in the world. Fruit juices, extracts, concentrates and processed edibles are consumed worldwide. Besides, plant fibres, enzymes obtained from the stems and leaves find many applications across industries. Pineapple residue mainly consists of pulp, stem, leaves and peels and the huge wastes produced as a result of improper handling, harsh environmental conditions, decaying and deterioration. Thesecan be successfully processed and extracted for further inexpensive and sustainable utilization instead of discarding. Agro-based and chemical industries have been switching to using plant-based substrates from various resources. Above all, all the natural substrates obtained are highly renewable, won’t contribute to the global waste production, require less expenditures in processing, less toxic and has considerably better biochemical properties than the synthetic alternatives.

Industrial Importance of Pineapple

Pineapple Leaf Fibre (PALF)

Back in the days, pineapple leaf fibre was considered to be an agricultural residue until it’s potential capabilities as an organic fibre and its commercial prominence heaved into view as a consequence of pioneering researches (Uddin et al.2017). According to Technical Association of Pulp and Paper Industry (TAPPI) standards, many chemical constituents like holocellulose, α-cellulose, lignin, and ash content of PALF were analyzed from a different source of f ibres, with varying environmental conditions, cost, etc. (TAPPI,1991). Mainly because of its highest tensile strength (413 to 1627 MNm−2), high cellulose content, as compared to other organic fibres with its Young’s modulus varying from 34.5 to 82.51 GNm−2. Furthermore, it has also been ascertained that upon its conversion to yarn, a 13% rise in its strength is observed and a bundle of saturated PALF adheres a reduced strength by 50% (Asim et al., 2015). Various researches and aided projects of SITRA (South India Textile Research) under UNDP/UNIDO have demonstrated the production of 100% PALF yarn by blending with other synthetic or natural fibres like cotton or silk. The threads, thus produced, are used to make fabrics, fancy carpets, mops, curtains, etc. where pineapple-jute blended yarns are used by the textile and fabric industries (Mishra et al., 2004; Debnath, 2016). It is also used in furnishings, decorations, sports items, baggage, quilts due to its aesthetic and elegant fabric (Anon, 1992).

Pineapples are commonly propagated through vegetative means, as the crop sets very few or no seeds and seeds possess slow germination process and low survival rate of seedlings under natural conditions. Vegetative parts such as stem suckers, peduncle slips, and fruit crowns are commonly utilized for vegetative multiplication of pineapple.

Selection of planting materials: Slips or hapa suckers are commonly preferred for commercial multiplication because they may produce fruit within 14-16 months after planting. Crowns are not commonly used as they may take up to 24 months after planting to harvest. Ground suckers (ratoon) and side suckers (side shoots) produce fruit 12-14 months and 18-20 months after flowering, respectively.(Pineapple Technical Group, 1999).

The fresh suckers should not be used for planting. Pineapple suckers should be stored for a few months to allow them to dry before planting, as they may begin to decay if planted in moist soil. Suckers are graded according to vigour and size, such as small, medium, and large. Planting the same graded suckers in the same plot helps to avoid uneven growth of the plant, uneven flowering times, and harvesting times. Additionally, using uniform planting material makes cultural practices easier, increases labour efficiency and other inputs, ultimately reducing the cost of cultivation.

Chadha et al. (1974) observed the superiority of slips and suckers as planting materials compared to crowns. In both slips and suckers, larger planting materials resulted in more vigorous plants. Medium-sized slips or suckers led to more flowering, while larger grade material resulted in a more staggered f lowering period. Smaller slips or suckers yielded fruit earlier. Slips produced better quality fruits, and the yields were comparable to the highest yield obtained with the largest suckers.

Pineapple is one of the most economically important fruits in tropical and subtropical regions and gaining popularity to the consumers all over the world. The pineapple plant has many specific morphological, anatomical and physiological characteristics that determine crucial aspects of pineapple crop management, such as water use efficiency, nutrient management, weed management, flower induction etc.

Water Requirements and Irrigation

Determination of water requirements and plant moisture status: Pineapple plant responds well to as much as 5 cm of water per month from rain or irrigation though it is a xerophyte type and is capable of good production under relatively meager water supply. Maintenance of available soil moisture in the root zone areas requires less water for pineapple than for other crops due to lower transpiration rates. Plants achieve this type of adaptability through a process called assuberization, where suberin act as a physical barrier, preventing water loss from the tissues it surrounds.Stomata remains closed as an effect of drought during the entire day. But, whenever the plants are grown with sufficient moisture in well-aerated soils produced well-distributed roots with numerous white root tips. It helps the water use efficiency and carbon f ixation that pineapple shows to drip irrigation. The pineapple leaf is a major water storage organ for the pineapple plant (Malézieux et al., 1993). When the leaves are full of water the cells present in upper mesophyll layer can occupy almost half of its volume. Invery little water-supply, the water in the mesophyll layer is absorbed by the plant. Generally, representative ‘D’-leaves are taken in a group of six to ten leaves and the total thickness is measured and compared with the thickness of fully turgid leaves.

Pineapple i.e. Ananas comosus (L.) Mer. belongs to the Bromeliaceae family, which has around 46 genera and 1700 species, mainly cultivated in the tropical and sub- tropical regions. It is ranked third in production of tropical fruit after banana and citrus. The pineapple market has been growing extensively due to the attractive aroma compounds and nutritional values as well as huge demand and competitive retail prices (Ali et al., 2020). But, several sanitary problems have been reported in pineapple and they are considered as the main constraints for low yield of that crop in several producing areas. Significant yield losses have been caused by infestation of different pests like mealy bug, fruit borer, mites, scale insects, as well as with different nematode species (Pires de Matos, 2017). The crop lifecycle phases, soil, climatic variables and crop management practices influence the pest infestation intensity. In order to prevent severe crop losses, an integrated approach comprising prophylactic, biological, cultural, mechanical and need-based chemical steps is most appropriate for controlling pineapple pests and maintaining their population below the threshold level. This chapter deals with globally important pests of pineapple with their nature of damages and effective control measures in depth.

Key Points

• Provide immediate first-aid for wounds.

• For bite wounds, open healing is preferable.

• Silver nanoparticles have antibacterial properties and have been investigated for anticancer applications.

Introduction

Cuts, tears, burns, fractures, and other forms of live tissue injury are all considered wounds. Wounds are typically classified as clean, contaminated, or diseased. Clean wounds are ones that occur in sterile settings, such as surgical incisions. The quantity of germs present distinguishes between contaminated and infected wounds.

Initial Wound Management

The initial step in wound management should be to assess the animal's general stability. Obvious open wounds can divert attention away from more subtle but possibly fatal conditions (such as shock). The general health of the animal influences all areas of care and healing. Some diseases, such as anemia, may impair wound healing by lowering oxygen levels. Malnutrition may also disrupt the healing process. After the initial assessment, the patient should be stable.

Key Points

• In diary animals, the health of the mammary gland (udder) is paramount.

• Any udder or teat disease state has a direct impact on milk output.

• Common udder/teet affections include: abscess, mammary gland hematomas, udder cleft dermatitis, udder edema, intramammary hemorrhage, teat damage, ulcerative mammillitis, udder dermatitis, and more.

Introduction

Mammary gland (udder) health is a crucial factor in animals used for production. The state of the udder determines the dairy industry's economics. The output of dairy animals is directly impacted by any udder ailment. Due to selection, breeding, genetic engineering, and animal management, animals under production pressure are more susceptible to a variety of diseases. More safety measures should be implemented in order to shield the udder from illness-causing factors. The many udder and teat affections and their therapeutic management are briefly discussed in this chapter.

Key Points

• Dogs exhibit respiratory distress symptoms more frequently than cats.

• Respiratory distress might have overt or covert clinical symptoms.

• The thorax and belly move paradoxically in cases of severe respiratory distress.

• Immediate intubation is the first step in managing a respiratory emergency: opening the airway.

Introduction

The telltale symptoms of "oxygen hunger" include tachypnea, stretched head and neck, abducted elbows, flare of the nares, cyanosis, open-mouth breathing, anxiety, and inability to lie down or relax. It is more usual for dogs than cats to exhibit symptoms of respiratory distress. Tachypnea and conspicuous breathing motions when in a sternal recumbency position are the only indications of respiratory dysfunction in cats, who often mask the severity of their illness. Despite their seeming stability, these patients are often extremely vulnerable and can rapidly decompensate when under stress.
