Concept of Evaluation: Meaning and concept in different contexts
The term “evaluation” originates from the Latin word “Valupure,” which signifies the value attributed to a particular entity, concept, or action. Evaluation is a systematic process that involves the periodic comparison of actual outcomes and impacts against those initially planned or anticipated. It is designed to assess the overall worth of an endeavor, thereby facilitating learning and improvements for future initiatives. This process encompasses the structured and objective assessment of an ongoing or completed project, program, or policy, including its design, execution, and results. The primary objective of
evaluation is to determine the relevance, achievement of objectives, efficiency, effectiveness, impact, and sustainability of a given intervention. Through this approach, evaluation seeks to provide credible and useful information that supports informed decision-making for stakeholders, including beneficiaries and donors. By integrating lessons learned from past experiences, evaluation enhances the strategic planning and implementation of future projects, ensuring continuous improvement and better resource utilization. Evaluation is an essential tool in both public and private sectors, allowing organizations to measure their performance against predefined benchmarks. It serves as a crucial mechanism for accountability, ensuring that resources are utilized effectively to achieve intended goals. Moreover, evaluation fosters transparency by offering objective insights into the successes and shortcomings of initiatives, thereby reinforcing stakeholder trust and engagement. There are several types of evaluation, each serving a distinct purpose.

Concept of Education

Education is derived from the Latin terms Educare (Educere) and Educatum. The word “educare” means to train, nourish, or shape. “Educere” means “to lead froth, to pull out.” The Latin term “Educatum” refers to the act of teaching. “Shiksha” and “Vidya” are two significant Sanskrit words that stand out as equivalents of English education. Shiksha is a word derived from “Shah,” which means “to control or discipline.” The term “Vidhya” is derived from the word “Vidh,” which means “knowledge.” During the ancient schooling period, the most essential aspects of human personality were discipline and knowledge.

Introduction
Fish and fisheries play a significant role in Kashmir's economy and people's livelihoods. Kashmir abounds with water bodies the lakes, rivers, and streams run the course to produce a favourable environment for numerous species of fish. Apart from the natural water bodies, fish farming has also emerged significantly in Kashmir, where several small-scale fish farmers are engaged in the fish rearing and fisheries activity in ponds and race ways, both for commercial and subsistence purposes (Islam, 2020). The fish farmers do more than just contribute to local food supplies; they also provide money and work for people locally. However, the fish and fisheries sector of Kashmir is faced with various challenges. The challenges range from overfishing, Exclusively Distributed by NIPA GENX Electronic Resources and Solution Pvt. Ltd. New Delhi environmental degradation, and pollution to the lack of infrastructure for fish handling and processing and climatic change. Despite all odds against this sector, the government and other agencies/organizations are trying their best to achieve sustainable management and development of fisheries in Kashmir. Moreover, full- and part-time work by fish farmers and fish workers, seasonal or occasional, supplement thousands of livelihoods with additional income in the sector's activities (Qayoom and Bhat, 2015). Most of those engaged in small-scale fisheries and aquaculture in Kashmir are self-employed, hence directly contributing towards food security within their households and communities. Due to the ever-increasing demand for protein-rich food, the production of fish has elevated around the world. According to the Food and Agriculture Organization, fish production attained 179.2 million metric tons in 2020, which is valued at USD 345 billion (FAO, 2020). This shows a large increase from the years of the 1990s when world fish production was 100 million metric tons.
Fish Production of India
Trends in fish production of India indicate a continuous rise of an annual average growth rate of 8.61% over the period from 2014-15 to 2021-22 (dof. gov.in). It is due to inland fisheries, which contributes around 75 percent of the total fish production in the year 2021-22, while the remaining 25 percent is from marine fisheries (dof.gov.in). Value-wise, the country's fish production has also had a massive outflow in exports, touching US$ 8.09 billion in FY 2022-23 (Handbook of fisheries statistics, 2023).

Fish and shellfish seed rearing, a crucial branch of aquaculture, involves the controlled breeding, nurturing, and development of aquatic organisms—primarily fish and shellfish—from their earliest life stages. This process ensures a sustainable and reliable supply of high-quality aquatic seed stock, especially vital in regions facing declining wild fisheries.
Seed rearing acts as the intermediate stage between hatching and grow-out. It focuses on the careful management of larvae or juveniles until they grow large enough to be transferred to grow-out systems such as ponds, cages, or pens. The main goal is to enhance survival rates, promote healthy growth, and produce robust fry or post-larvae that can thrive in commercial farming conditions.
In aquaculture terminology, “seed” refers to young aquatic organisms—fish fry, fingerlings, or shellfish post-larvae—sourced either from hatcheries or natural environments. These early-stage organisms are highly vulnerable to environmental changes and disease, requiring meticulous care. Success during this stage depends on optimal nutrition, water quality control, and disease management.
The seed rearing process typically begins shortly after hatching. For fish, stages include yolk-sac larvae, free-swimming larvae, fry, and fingerlings. For shellfish such as shrimp, development proceeds through nauplii, zoea, mysis, and post-larvae stages. Each phase demands close attention to water parameters like temperature, salinity, oxygen levels, and hygiene.
Seed rearing can take place in a variety of systems—indoor tanks, nursery ponds, hapa nets, or specialized seed rearing facilities—depending on the species and production scale. In India and other tropical regions, both extensive systems (natural feed-based) and intensive systems (involving formulated feeds and aeration) are widely practiced. Innovations such as biofloc technology, probiotics, and recirculating aquaculture systems (RAS) have significantly improved outcomes.

Fish nutrition is a key component of aquaculture, as it directly affects the growth, health, reproduction, and overall efficiency of farmed species. Unlike land animals, fish primarily obtain their energy from proteins and fats, making their dietary needs distinct and specific to each species. With the expansion of aquaculture and rising demand for high-quality fish protein, ensuring nutritionally balanced diets for fish has become increasingly important. Fish require both macronutrients—proteins, fats, and carbohydrates—and micronutrients, including essential vitamins and minerals. Proteins are especially important for tissue building and enzymatic functions, while fats provide energy and vital fatty acids needed for cell membranes and hormone synthesis. Although carnivorous fish digest carbohydrates less efficiently, they are still used as a low-cost energy source. Vitamins such as A, D, E, and C, and minerals like calcium, phosphorus, zinc,

Fish pathology is a specialized area within veterinary and aquatic sciences that focuses on understanding diseases affecting fish—their origins, progression, effects, and methods of control. With aquaculture playing an increasingly critical role in meeting global protein demands, maintaining fish health is essential for the long-term viability and efficiency of aquatic farming. Like other animals, fish are prone to numerous diseases caused by a variety of pathogens, which can impact both wild and farmed species, leading to serious economic, ecological, and health issues.
The field draws on various disciplines, including parasitology, immunology, microbiology, histopathology, and molecular biology, to study disease mechanisms and how fish interact with infectious agents. Disease outbreaks in fish may stem from infections, poor environmental conditions, overcrowding, or insufficient nutrition. Among these, infectious diseases pose the greatest threat, caused by viruses, bacteria, fungi, and parasites, each differing in severity, transmission methods, and environmental resistance.
Viral infections, such as those from IHNV or KHV, can rapidly spread and cause high death rates, particularly in hatchery environments where treatment options are limited. Bacterial diseases, triggered by agents like Aeromonas hydrophila, Vibrio anguillarum, or Edwardsiella tarda, often enter through damaged skin or gills, causing ulcers, bleeding, and internal organ damage. Fungal diseases, like those caused by Saprolegnia, are usually secondary infections that develop when fish are already weakened. These fungi attack the skin and gills, forming cottonlike lesions and damaging tissue.

In broad perspective, forages are plants and crops used for animal feeding. It includes all the natural and cultivated crops, shrubs, and trees etc., used in livestock feeding. Here, fodder specifically denotes the cultivated crops exclusively used for livestock feeding. Though, they are synonymously used in books, a student of veterinary science should able understand the difference between forages and fodder. Fodder is a term mainly used in intensive livestock farming where stall feeding is preferred over grazing to optimize the efficiency of production per unit area. Though, most of the tree's leaves are used for animal feeding, some of the trees being cultivated exclusively for animal feeding and those are called fodder trees and others called as multipurpose trees.

1. Sample: One or more units selected from a population of units, or a portion of material selected from a larger quantity of material
2. The Standard Operating Procedures (SOPs) should contain full working instructions as well as information on applicability, expected performance, internal quality control (performance verification) requirements and calculation of results. It should also contain information on any hazards arising from the method, from standards or from reagents.
3. Analytical Samples: The quantity of the analytical sample to be used is usually indicated in tests and assays. Unless otherwise specified, the quantity used may deviate by 10% from that stated. All quantitative determinations should be conducted on triplicate test portions and in these cases, the amount actually taken should be accurately weighed or measured and the result of the analysis calculated on this exact quantity. When substances are to be “accurately weighed” in a test or assay, the weighing is to be performed in such manner as to limit the error to ± 0.1% or less. Quantities smaller than 100 mg should be weighed to the nearest 0.1 mg.

1.1. Introduction

Food packaging involves enclosing the food product to ensure its safe delivery to end consumer in safe condition. Packaging is one of the integral components of the food industry. In order to maintain the basic nutritional and functional attributes of food material, they must be packaged safely. A faulty package can ruin all the efforts made to develop the food product. Selection of right packaging system and packaging material is essential to arrest the deterioration of food products from physical, chemical and biological factors. 

In today’s global food industry, packaging has evolved into an essential component that extends beyond basic containment. The rapid expansion of food distribution networks and increasing consumer demand for quality, convenience, and safety have transformed packaging into a sophisticated, multi functional system. Food packaging now serves critical roles in preservation, safety, marketing, and sustainability, aligning with both global and regional standards that cater to a wide array of consumer needs. This chapter provides an overview of the importance of food packaging, discusses the current landscape in both global and Indian markets, identifies key trends and challenges, and explores packaging’s role in the modern food supply chain. Each section aims to illustrate how food packaging impacts food quality, longevity, and overall consumer satisfaction, highlighting the industry’s ongoing innovations and adaptations to regulatory and environmental concerns. 1.1 Definition and Significance of Food Packaging Definit

Food safety and hygiene has been an age-old concern. However, today it has become an important aspect due to the rise in foodborne illnesses for the past few decades globally. It is estimated by WHO that annually 600 million suffer from foodborne diseases as a result of unsafe food consumption while 4,20,000 deaths are recorded globally.

Food Science is one of the ancient sciences and the genesis originates to the very beginning of human civilization. The advent of food science was associated with practice and observation by humans before establishment of scientific concepts. The ancient man knew that roasting or smoking of meat improves the edible quality and digestibility. As a consequence, he started practicing the same much before the reasons for the same could be established. Many of the modern preservation concepts had their origin in prehistoric period itself as humans could use techniques such as dehydration, fermentation and pickling to their advantage to improve the sensory attributes of the products and also to enhance their shelf life. Humans during the Pre-Neolithic period about 2,50,000 years before used fire for cooking meat. During the Paleolithic period humans not only roasted food but also developed grinding, pounding and drying. During the Mesolithic era, humans were desperate for food and got involved in extensive hunting and fishing. During the same time domestication of animals took place and animal husbandry became a reality (Stewart and Amerine 1982). The Neolithic period made qualitative changes in the food habits of humans and they changed from a food gathering and hunting society to one of food production (Heizer and Elsasser 1980).

INTRODUCTION

Fish culture as a hobby or business is well established in India. Increased interest in fish culture has also increased awareness and experience with parasites that affect fish health, growth, and survival. Information provided in this chapter is intended for the novice fish culturist as a guide to common parasites of freshwater fish. Identification of parasites and their basic treatment is included; however, any herbal treatment alone or biological cum chemical treatment may be choosen for eradication purpose (Das et al., 1995a).

A Overview

Genetics is a branch of biology concerned with heredity and variation.

Genes are the unit of inheritance and are composed of DNA.

The effects of genes are noticeable at the molecular, cellular, family, and population levels.

Genes are DNA sequences that instruct cells to produce particular proteins, which in turn determine traits.

Genes can exist in more than one form and the variants of a gene arise by mutation.

An allele is a variant of a gene that alters its expression in a detectable way. Alleles can be dominant or recessive.

A polymorphism is a particular sequence of DNA that varies in one percent or more of the population.

Single nucleotide polymorphisms are single base pair sites that differ among individuals.

Chromosomes consist of genes and associated proteins.

The human genome consists of 22 pairs of autosomes and one pair of sex chromosomes.

A karyotype is the photographic catalog of the human chromosomes.

Specialized cells and tissues arise by differentiation from the stem cells of the early embryo.

Pedigree diagrams enable recessive and dominant traits to be followed through multiple generations of a family.

A gene pool is the collection of alleles in a population.

Comparative genomics is leading to a more detailed and subtle understanding of evolutionary relationships among species

Introduction

A geographic information system or geographical information system (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present all types of spatial or geographical data. The acronym GIS is sometimes used for geographic information science (GIScience) to refer to the academic discipline that studies geographic information systems and is a large domain within the broader academic discipline of geoinformatics. What goes beyond a GIS is a spatial data infrastructure, a concept that has no such restrictive boundaries. In a general sense, the term describes any information system that integrates stores, edits, analyzes, shares, and displays geographic information. GIS applications are tools that allow users to create interactive queries (user-created searches), analyze spatial information, edit data in maps, and present the results of all these operations. Geographic information science is the science underlying geographic concepts, applications, and systems.

GIS is a broad term that can refer to a number of different technologies, processes, and methods. It is attached to many operations and has many applications related to engineering, planning, management, transport/logistics, insurance, telecommunications, and business. For that reason, GIS and location intelligence applications can be the foundation for many location-enabled services that rely on analysis and visualization. GIS can relate unrelated information by using location as the key index variable. Locations or extents in the Earth space–time may be recorded as dates/times of occurrence, and x, y, and z coordinates representing, longitude, latitude, and elevation, respectively. All Earth-based spatial–temporal location and extent references should, ideally, be relatable to one another and ultimately to a “real” physical location or extent. This key characteristic of GIS has begun to open new avenues of scientific inquiry.

Introduction
Good Laboratory Practices (GLP) are a quality system concerned with the organizational process and the conditions under which non-clinical health and environmental safety studies are planned, performed, monitored, recorded, archived, and reported. GLP ensures the quality and integrity of the study process rather than the scientific validity of the study itself. It provides a framework for ensuring that data generated in non-clinical safety studies are reliable and reproducible, thereby facilitating the mutual acceptance of data by regulatory authorities worldwide (OECD, 1998; US EPA, 2016). GLP represents a structured quality system designed to ensure the consistency and reliability of non-clinical safety studies. It establishes a framework encompassing organizational processes and laboratory conditions, with a focus on:
1. Systematic Study Conduct: GLP mandates a methodical approach to the planning, execution, supervision, recording, reporting, and archiving of studies.
2. Data Integrity Assurance: The primary objective is to guarantee the dependability of data generated, thereby fostering confidence in safety assessments.
3. Regulatory Compliance Support: GLP facilitates adherence to regulatory standards, enabling the acceptance of study findings by authorities worldwide.
4. Non-Clinical Safety Focus: It specifically applies to studies that precede human clinical trials, particularly those evaluating the potential hazards of chemical substances (OECD, 1998).
In veterinary and allied fields, GLP extends beyond general scientific rigor to address the unique challenges of animal health, food safety, and environmental protection related to animal populations. It ensures the reliability and traceability of data generated in studies related to veterinary pharmaceuticals, feed additives, diagnostics, and environmental toxicology involving animals. The focus is on maintaining the integrity of studies that directly impact animal welfare, public health, and agricultural sustainability (World Organization for Animal Health, 2018; FDA, 2010). In the context of veterinary medicine or treatment aspects, GLP in veterinary refers to a a well organised quality system that governs the organization and conditions under which non-clinical studies related to animal health and safety are planned, performed, monitored, recorded, reported, and archived. This includes:

For millennia, humans have forged an intimate relationship with the natural world, recognizing and harnessing the therapeutic potential of plants for healing. This unit, “Introduction to Herbal Medicines,” embarks on a comprehensive exploration of plant-based therapies, delving into their historical evolution, fundamental terminology, integration within traditional healing systems, and the practical aspects of their cultivation, processing, and utilization. We aim to provide a solid bedrock of knowledge, enabling a deeper understanding of the science and practice of herbal medicine, and appreciating its enduring significance in the modern world."
1. History and Scope of Herbal Medicines
1.1 Ancient Beginnings: The Dawn of Plant-Based Healing
• Paleolithic Roots: Our most ancient ancestors, from the Paleolithic period, are believed to have harbored a refined comprehension of the pharmacological attributes of vegetation. Excavations have unearthed indications of specific plant utilization for addressing physical trauma and maladies, underscoring an early grasp of their remedial efficacy. This knowledge was likely passed down through oral traditions, forming the foundation of future herbal practices.
• Civilizational Emergence: With the rise of civilizations, medicinal plant use became more structured and recorded. In ancient Sumeria, clay tablets inscribed with cuneiform script, dating back to 3000 BC, record the use of various plants for medicinal purposes, showcasing organized knowledge of herbal remedies. The Egyptian Ebers Papyrus (c. 1550 BC), a remarkable medical text, provides detailed prescriptions for treating a wide array of ailments using plants like aloe vera, garlic, and opium, evidencing a sophisticated understanding of pharmacotherapy. In India, the ancient system of Ayurveda, with its foundational texts, the Charaka Samhita and Sushruta Samhita, meticulously documents the use of numerous medicinal plants, emphasizing a holistic approach to health. Similarly, Traditional Chinese Medicine (TCM), with the Shennong Bencao Jing (c. 1st century AD), provides a comprehensive pharmacopeia, demonstrating the profound integration of herbal remedies into Chinese medical practice.

The term ‘Horticulture’ is derived from two Latin words, Hortus meaning Garden and Cultura meaning Cultivation. In ancient days the gardens had protected enclosures with high walls or similar structures surrounding the houses. The enclosed places were used to grow fruits, vegetables, flowers and ornamental plants. Horticulture differs from agriculture and forestry in specializing the cultivation of garden crops. The garden crops include fruits, vegetables, flowers, ornamental trees, spices, plantations, medicinal and aromatic plants. Horticultural crops do not give food grains. The products of horticultural crops such as fruits and vegetables are highly perishable so that they are utilized in the fresh state. In general horticultural crops need more intensive cultivation (i.e. need more work) than the agricultural crops.

Special Features of Horticulture

As horticultural crops generally need intensive cultivation, they require a large input, capital, labour and technology per unit area of land.

Many cultural operations are specific to horticultural crops. The cultural operations such as propagation, fertilization, training, pruning, harvesting and marketing are skilled operations and these are specific to horticultural crops.

Mostly the horticultural products are utilized in the fresh state and are highly perishable.

Most of the horticultural crops are the rich sources of vitamins and minerals.

Gratification or aesthetic sense is an exclusive phenomenon for horticultural science.

Background
Cells are the basic unit of life. The morphology of cells describes their structural framework. It refers to the morphological features of the cell(s). It comprehends the various shapes and sizes in which cells function. Thus, the shape and size of the cell and the number of cells indicate their functional status. Hematological diagnostics requires the proper assessment and valid classification of cells for final diagnosis and prognosis. Clinicians, patients, and diagnosticians are all concerned with achieving a definitive specific diagnosis employing a single investigative test. The utilization of different cytological examinations from different organs gives adequate indicative data that leads to treatment outcomes.
What is ImageJ?
ImageJ is a public-domain image processing and analysis software that is Java-based and developed by the National Institutes of Health. The software is used to process and analyze scientific images.
The key features of ImageJ are 1) the versatility of working with various image formats, 2) extensibility with several plugins, 3) multidimensional data handling capability, and 4) vibrant community, making ImageJ a unique software for image processing and analysis. It can run as an online applet or be downloaded and used as an app.

Introduction

Impact studies isolate the effect of an intervention by assuring that there is clean comparison between a treatment group that received the intervention and a comparison group that is just the same except that it did not get the intervention.

Impact studies test whether one thing causes another. Just knowing scores have gone up following an intervention doesn’t mean improvement is attributable to that intervention.

The data are generated from an impact study used to identify best practices, to replicate successful programs or policies, and to avoid mistakes that might have negative implications for future projects.

Introduction
Impact Assessment (IA) is a systematic process used to evaluate the potential or actual effects of a project, policy, or program on society, the economy, and the environment. It helps decision-makers understand the implications of their actions and ensures that interventions achieve their intended outcomes while minimizing negative consequences.
Meaning of Impact Assessment
Impact Assessment is a structured method of determining the significance of an action or intervention in various sectors. It involves analyzing both the intended and unintended effects of policies, projects, or programs. IA provides insights into the sustainability, feasibility, and effectiveness of an initiative before or after its implementation. By assessing social, economic, and environmental impacts, IA helps stakeholders make informed decisions.
Concept of Impact Assessment
The concept of IA is rooted in sustainable development and evidencebased policy making. It is used in multiple fields, including environmental management, social development, economic planning, and corporate governance. The key principles of IA include:"
i. Comprehensiveness: Evaluating a wide range of impacts, including social, economic, and environmental factors.
ii. Transparency: Ensuring that the assessment process is open and inclusive.

Introduction
As global populations increase, so does the demand for high-quality seafood. Aquaculture has emerged as a vital solution, contributing significantly to global fish production and food security. However, traditional practices in fisheries nutrition, primarily reliant on fishmeal and fish oil, face substantial challenges. Overfishing, rising feed costs, and environmental concerns necessitate a shift towards more sustainable and innovative approaches in aquaculture nutrition. This chapter delves into the innovative methodologies and technologies shaping the future of fisheries nutrition, emphasizing sustainability, health, efficiency, and the optimization of nutritional strategies.

Integrated fish farming is based on the concept that ‘there is no waste’, and waste is only a misplaced resource which can become a valuable material for another product. In integrated farming, the basic principles involve the utilisation of the synergetic effects of inter-related farm activities and the conservation, including the full utilisation of farm wastes. It is assumed that all the constituents of the system would benefit from such a combination. However, in most cases, the main beneficiary is the fishes which utilises the animal and agricultural wastes directly or indirectly as food. As integrated farming involves the recycling of wastes, it has been considered an economic and efficient means of environmental management. Integrated fish farming, also known as rice-fish culture, is an age-old practice that combines aquaculture and rice farming. This method has gained renewed interest due to its potential to increase agricultural productivity and sustainability.

Intellectual Property Rights (IPR) refer to the legal rights granted to creators, inventors, and innovators for their intellectual creations. These rights enable individuals or organizations to control and benefit from the use of their creations for a certain period. In the era of rapid advancements in biotechnology and molecular biology, IPR has emerged as a cornerstone in protecting and commercializing innovations in plant genetics, genetic engineering, bioproducts, and molecular tools.
The concept of IPR is rooted in the recognition that ideas, like physical property, hold economic value and deserve legal protection. IPR plays a pivotal role in encouraging innovation, fostering technology transfer, promoting research investment, and ensuring economic returns to developers. In biotechnology, IPR has direct implications on transgenic technologies, bioinformatics, novel genes, enzymes, diagnostic kits, and biopharmaceuticals.
1.1 Evolution and Historical Background of IPR
1.1.1 Introduction
The concept of Intellectual Property Rights (IPR) has evolved over centuries as a legal framework to protect creations of the human intellect. While the terminology “intellectual property” is relatively modern, the underlying idea—that inventors, artists, and creators deserve recognition and protection for their innovations—has ancient roots. In the context of modern biotechnology, IPR serves not only as a legal safeguard but also as a vital tool to stimulate innovation, secure investments, and promote equitable commercialization.
Understanding the historical trajectory of IPR helps contextualize contemporary debates on the ownership of genetic resources, traditional knowledge, and the ethical implications of patenting life forms.

Intellectual property (IP) refers to the creations of the human mind that can be protected and have commercial value. These creations, or “intellect,” can take various forms, such as inventions, artistic works, and designs. Converting intellectual property into a useful product or process requires resources like time, effort, skill, and financial investment. Intellectual property rights (IPR) are legal rights granted to innovators and creators, giving them exclusive control over the use and monetization of their inventions and creations. IPRs are territorial and allow creators to sell, license, transfer, or otherwise dispose of their rights, similar to physical property.

IPRs are considered crucial for promoting economic growth and development, as they encourage innovation, investment, and entrepreneurship. Without IPRs, inventions and creative works could be easily copied or stolen, resulting in reduced incentives for innovation and decreased economic value. Lack of IPR can also lead to an increase in infringements and economic losses. In recent years, India has been increasing its awareness of IPR and has seen a rise in registrations of indigenous technology, patents, trade secrets, and copyrights among others.

The Internet of things connects the devices over Internet. The devices can communicate with each other and can be monitored and controlled remotely. The IoT is a system with interrelated computing devices, digital and mechanical machines, objects, animals or people each with an unique identifiers (UIDs ). It has the ability to transfer data over a network without human intervention. The Internet of Things is simply a network with Internet connecting the objects to collect and exchange the data. This chapter covers the basics of Internet of Things and its components.

2.1 Characteristics of IoT

Internet of Things can be used to design products for businesses. The added value to the businesses over IoT is created by the information which is collected by connected devices. The process has five phases of lifecycle, first phase is ‘create phase’, where sensors collects the data from environment. This data can generate the information. Second is ‘communicate phase’ where data generated in first phase is communicated to the required destination. Third is ‘aggregate phase’ where collected data over network is aggregated by device itself. Fourth is ‘analyse phase’ where aggregated data is used to generate patterns and use it to control and optimize the process. Fifth is ‘act phase’ where actions are taken on the basis of information extracted from the aggregated data.

The characteristics of IoT may vary from one domain to other. Few characteristics are listed as follows-

To understand IoT “Internet of Things” it is important to understand internet first. Internet is connecting a device to other device anywhere in the world. When two devices are connected with the Internet, they can send and receive all kinds of information such as text, graphics, voice, and video. The high-speed, fiber-optic cables are used, through which the bulk of the Internet data travels. The Internet has revolutionized the communication world. In today’s scenario the internet is an important part for people around the world. The Internet is a global network of billions of electronic devices. The World Wide Web (www) is most widely used part of the Internet.

The “Internet of Things is a potentially integrated part of the ‘Future Internet’. IoT can be defined as a dynamic global network with self - configuring capabilities based on communication protocols where physical and virtual ‘Things’ interact with each other.

The Internet of Things (IoT) is inter-connecting the networks of smart devices. Smart devices may be embedded with vehicles, buildings, or other electronics object with software, sensors, actuators, and network connectivity. Network connectivity enables smart devices to collect and exchange data. The Internet of Things (IoT), also referred to as the Internet of Everything (IoE) which comprises of the web-enabled devices. IoT has its applications in smart city, smart surveillance, automated transportation, smarter energy management systems, water distribution, urban security and environmental monitoring. Agriculture is another new area of IoT application.

Due to advancement in technology the processing power and storage capacity has been increased, in the recent years. At the same time technology is making the devices pervasive, wearable and mobile. Smart devices are fitted with sensors, actuators which enable devices to sense, compute and act intelligently. They are able to exchange information with environment.

This is a branch of veterinary science that deals with the biology of animal when they are in good health condition, disease status and also deals with the selection of the laboratory animal, important care to be taken and also the usage of these laboratory animals in experiment and also for other research activities.

IMPORTANCE / SCOPE FOR STUDY

Veterinarian with special training/ advanced training in laboratory animal medicine and management are required by medical school, pharmaceutical industries, private and government organization, hospitals, research institutes.

This field of veterinary science has become highly dynamic and it provides good opportunities to satisfy academic professional career.

Usage of these laboratory animals goes back to 2^nd Century. However, the systematic and systemic usage came into existence a century back when research workers started working on polio vaccine. Since then, a debate is going on between scientists of different organizations regarding the usage of laboratory animals.

The science of Meteorology is defined as the science that deals with physical and chemical processes of the lower atmosphere. The physical and chemical changes in the lower atmosphere produce weather and popularly known as the weather science. The weather science concerns the study of structure, state and behaviour of the lower atmosphere. It is essentially an observational science dealing with different atmospheric variables such as atmospheric pressure, temperature, wind, humidity, density, cloud amount, radiation, precipitation and related variables at a given moment and attempts to predict the behaviour of atmosphere over a period of few hours to few days ahead and disseminate the same in time to the users? community. The statistical approach of weather phenomena deals with the mean state of the physical properties of atmosphere. This branch of science is popularly known as Climatology. The weather science can be categorized into several branches based on method of approach, purpose and function, scale and region. Based on the purpose and function, it can be divided into several branches like Livestock Meteorology, Agro Meteorology, Forest Meteorology, Hydro Meteorology and Bio-Meteorology (Fig 1.1).

Animal husbandry is the most important economic activity in rural areas as livestock plays a vital role in the economy. Over 90 per cent of the milk production comes from small farmers, who are located in rural areas. Growing human population, increasing urbanisation, rising domestic incomes and changing lifestyles in the country have led to increasing demand for dairy products (Anita and John, 2001).

Introduction Market led extension effectively delivers sufficient and high-quality information to farmers so they can make decisions about production and marketing that willmaximize their return on investment without endangering the needs of future generations. Farmers must improve from being producers or sellers in the home market areas to producers cum sellers in a large market to best reap the benefits of their products. This necessitates the transfer of new extension strategies involving a range from local market to export markets, subsistence to commercial agriculture, productivity to profitability, commodity-oriented to farming systemsoriented, mono-cropping to varieties of crops, and so forth. The extension agents’ attention must be diverted from production in some way. Reducing production costs, increasing product value, and enhancing marketability will assist the farming community in receiving high returns for the products.

Introduction
Generally, muscles and offals obtained from animals feeding on grass and various other cultivated crops are regarded as meat. Apart from the meat obtained from the cattle, sheep, goat, pig and poultry, in many countries particularly Denmark, Belgium, Holland and Germany, horse meat is also consumed (hippophasia) as normal meat. Kangaroos are slaughtered for meat in Australia whereas capybara a large semi-aquatic vegetarian rodent, is used in South America as of one of the meat source. Dog meat (fragrant) is relished (Kinophasia) in few cultures such as South Korea, China, Vietnam and few north eastern states of India.
In many parts of the world including Indian subcontinent, buffalo meat (Bubalus bubalis), also known as water buffalo or arna, is quite popular owing to its tenderness, leanness and low cholesterol qualities. It is distributed in many countries around the world such as India (largest population), Pakistan, China, Bangladesh, Indonesia, Philippines, Hungary, Italy and France etc. Bison (Bison bison) from North America is also called buffalo but they are separate species of the order Bovidae. Rabbits are also source of meat having higher growth rate and better feed conversion ratio (2:1). Elands are another meat source which are raised in Africa and Russia for meat purpose.
Meat is quite high in protein content but the presence of saturated fat is perceived negatively due to its association in various cardiovascular diseases, diabetes etc. Efforts are made to produce lean meat having higher content of unsaturated fatty acids and to reduce the ω-6 to ω -3 fatty acids ratio.

Meteorology is the scientific study of the atmosphere. It focuses on the physical processes and phenomena that occur within the Earth’s atmosphere, including weather and climate. Meteorologists study these processes to understand, explain, and ultimately forecast the Earth’s weather.
Think of the atmosphere as a vast and dynamic fluid that surrounds our planet (Fig. 1.1). Meteorology seeks to understand:
• Composition of the atmosphere: What gases and particles make up the air we breathe?
• Structure of the atmosphere: How is the atmosphere layered (e.g., troposphere, stratosphere)?
• Atmospheric motion: Why does the wind blow? What drives air currents?
• Energy balance: How does the Earth receive and redistribute energy from the sun?
• Formation of weather phenomena: How do clouds, rain, snow, storms, and other weather events develop?

1.1 Introduction
Meteorology, at its heart, is the scientific endeavor dedicated to understanding the Earth’s atmosphere and the myriad phenomena that occur within it. More than just the art of predicting whether it will rain tomorrow, meteorology is a robust interdisciplinary science. It intricately weaves together principles from physics, chemistry, and mathematics to unravel the complexities of atmospheric processes. From the gentle caress of a breeze to the formidable power of a hurricane, meteorology seeks to explain the underlying mechanisms that drive our ever-changing weather and long-term climate patterns.
The study of meteorology encompasses a wide array of atmospheric characteristics. Meteorologists delve into the composition of the atmosphere, examining the various gases and tiny particles known as aerosols that reside within it. They also investigate its vertical structure, distinguishing between layers like the troposphere, where most weather occurs, and the stratosphere, home to the ozone layer. The motion of the atmosphere, manifested as wind systems ranging from local gusts to global circulations, is a central focus. Furthermore, meteorology explores the thermodynamics of the atmosphere, including how heat is transferred and how temperature changes, as well as the role of water in the atmosphere, from humidity to the formation of clouds and precipitation – the realm of atmospheric hydrology. Even the captivating
optical phenomena we sometimes witness, such as rainbows and halos, fall under the purview of meteorological inquiry.

Microscope is an instrument to magnify and enable to see the microorganisms by us.

Microscopes are of two types. Light and Electron microscope.

Basic Principles of light microscope

The light is the primary source on which magnification is performed. The magnification is obtained by a system of optical lenses using light waves. These light microscopes can be further classified into

Molecular biology is a branch of science that deals with understanding the biological activities at the molecular level. Molecular biologists are involved in understanding the concepts behind various intra and intercellular interaction of molecules, contributing to the knowledge about interrelationship of DNA, RNA and protein synthesis, i.e., how genes are transcribed into RNAs and how RNA is translated into protein, the phenomenon which is commonly known as “Central Dogma”stated by Francis Crick in 1956.

“The central dogma of molecular biology deals with the detailed residue-by-residue transfer of sequential information. It states that such information cannot be transferred back from protein to either protein or nucleic acid”-Francis Crick.

Mycotoxins are the secondary metabolites produced by moulds, which grow on food and feedstuffs causing pathological or physiological changes to humans and animals. They are toxic to vertebrates in low concentrations. Symptoms depend on the amount of toxin in the feed, the period for which the infested feed is ingested, the nutritional status of the feed and the susceptibility of the animal species. Toxic effects of chronic consumption of mycotoxins in human are carcinogenicity, hepatotoxicity, oestrogenicity, genotoxicity, nephrotoxicity, immunosuppression, reproductive disorders and dermal irritation (Anfossi et al., 2010). The most extensively studied mycotoxins viz., Aflatoxins, ochratoxins, deoxynivalenol (DON, vomitoxin), T-2 toxin, zearalenone, fumoninsins, mycophenolic acid, cyclopiazonic acid and ergot toxins are produced by the moulds Aspergillus, Fusarium, Pennicillium and Claviceps (Iqbal et al., 2015).

Natural Farming (NF) represents a sustainable approach to agriculture that draws upon ecological principles, minimizes reliance on external inputs, and makes extensive use of locally available resources. In contrast to conventional farming—which often depends on synthetic fertilizers and commercial animal feed—natural farming seeks to foster balance among the soil, crops, animals, and microbial life. Popularized in India by Subhash Palekar, this method promotes the use of natural preparations such as Jeevamrit, Beejamrit, and practices like mulching to enrich soil fertility and support plant vitality.
A core aspect of natural farming is the inclusion of livestock, which significantly contributes to nutrient recycling, weed suppression, and overall farm efficiency. Products like cow dung and urine form the basis of microbial formulations that boost soil activity and crop productivity. Livestock also contribute to ecological health through regulated grazing, pest management, and the breakdown of organic residues.
Animals such as cows, buffaloes, goats, sheep, backyard poultry, and fish are effectively integrated into the NF system to form a cohesive and regenerative agro-ecosystem. These animals enhance crop systems by providing organic inputs while simultaneously benefiting from pesticide-free fodder and farm-generated feed, leading to healthier livestock and improved quality of dairy, eggs, and meat.
This interdependent model reduces the need for external feed inputs, enhances natural animal wellness, and raises farm income, particularly for smallholders. Natural farming promotes the use of native breeds that thrive in local conditions with minimal intervention.
Ultimately, integrating livestock within natural farming is not just beneficial— it is vital for establishing robust, regenerative farm systems. This synergy between animals and crops supports ecological sustainability, strengthens food systems, and uplifts rural communities.

India achieved food security through the adoption of high-yielding seed varieties, chemical fertilizers to boost soil nutrition, and pesticides to protect crops. However, this progress came at an environmental cost, including excessive fertilizer use that harmed both human and ecological health.
Natural farming, or prakritik kheti in Hindi, represents a traditional yet evolving approach to agriculture that promotes ecological balance, self-reliance, and sustainability. It is deeply embedded in India’s agricultural legacy, where for centuries, farming was done without synthetic chemicals or mechanization. Today, it is gaining renewed importance as a viable alternative to input-intensive farming, offering solutions to challenges like soil depletion, falling groundwater levels, rising costs, and environmental degradation.
Natural farming operates on the belief that nature is inherently self-sustaining. It avoids the use of chemical fertilizers, pesticides, and GMOs, instead relying on natural, locally sourced inputs to boost soil health and crop yield. This method emphasizes collaboration with nature rather than domination over it. Subhash Palekar’s “Zero Budget Natural Farming” (ZBNF) model, based on low-cost and chemical-free techniques, has been especially appealing to small and marginal farmers.
Soil health is central to natural farming. Techniques like mulching with crop waste, applying jeevamrit (a fermented solution of cow dung, urine, and natural additives), and treating seeds with bijamrit are widely used. These enhance soil microbes and improve its capacity to retain water and nutrients. Natural farming also promotes biodiversity through intercropping, crop rotation, and the use of indigenous seeds.

Theophrastus gave the name “ORCHIDS” to the group of bizarre plants on the basis of the resemblance of paired underground tubers of these plants to masculine anatomy. This resemblance was also responsible for the mistaken belief that the orchids posses aphrodisiac properties and eating of underground tubers might “provoke venus” and they may be get male children. The appreciation of orchid beauty has a very long history in both the Western and Eastern cultures. Much of this is attributed to the diverse form and structure of orchids and the large number of species in the orchid family. Orchidaceae is amongst the most diverse family of the flowering plants consisting of 35,000 species under 880 genera (Kumar and Sheela, 2007, Fay and Chase, 2009). Orchids belong to the highest level of organization and are distinguished by the complicated biology of reproduction with long developmental cycle (Vakhrameeva et al., 1991, Sherif et al., 2012). They are beautiful and exotic perennial herbs grown in both north and south hemispheres. They exhibit an incredible range of diversity in size, shape and colour of flowers. Its flowers have lustrous, translucent petals rich in variegated colors and fragrances. Generally Orchids can grow at different elevations (Kumar and  Sheela, 2007).

Abstract

An intellectual property infringement is the violation of an intellectual property right of the owner. Infringement is established based on the law governing appropriate IPR in the concerned country. Both civil and criminal remedies are available under the concerned law. The present paper introduces the patent infringement as per Indian Patent Act, 1970. It discusses various modes and types of infringements which can take place. It further discusses a procedure to formulate opinion about product infringing a granted patent. In the end some usual defenses against patent infringements have been discussed. Some case studies have also been presented along with the damages awarded for the patent infringement.

Anatomy

The study of gross internal structure of plant organs by the technique of section cutting is called anatomy .The term anatomy was derived from two words ‘ana’ means as under and ‘temnein’ meaning to cut. Anatomy is the branch of science which deals with internal structures and organization of the organism. It is also known as internal morphology. Plant anatomy also describes tissue and tissue systems of the plant body.

Biosecurity refers to the measures aimed at preventing the introduction and/or spread of harmful microorganisms to animals and plants in order to minimize the risk of transmission of infectious disease. Biosecurity is of growing interest as a result of developments at the international level, including globalization of the world economy, technological progress and the rapid increase in communications, transport and trade. Against this background, there is concern that the appropriate level of protection of human, animal and plant life and health is not being maintained as risks increase. Biosecurity is a strategic and integrated approach that encompasses the policy and regulatory frameworks for analyzing and managing relevant risks to human, animal and plant life and health, and associated risks to the environment. 

Several definitions of plant breeding have been put forward. All of these have a core component of the definition that is “the art and science of improving the heredity of plants for the benefit of the humankind” as mentioned by famous plant breeding teacher and a popular plant breeding text book author, J. M. Poehlman. N. I. Vavilov has defined plant breeding as “evolution directed by the will of the man”. The most modern definition of plant breeding by Bernardo (2002) is “plant breeding is the science, art, and business of improving plants for human benefit”. A few more definitions on these lines given by several other famous plant breeders are as follows.

Plant Pathology
The term Plant Pathology is derived from greek words- pathos (suffering) + logos (study) i.e. the study of the suffering plant. Plant Pathology has two phases broadly-
• Science- Understanding of the disease i.e. the theoretical consideration of the suffering plants and how do pathogens invade, how do plants defend themselves, what causes symptoms etc.
• Art- The application of the science to the field problems i.e. Diagnosis and Control.
Plant pathology or phytopathology is the branch of agricultural, botanical or biological science which deals with the cause, etiology, resulting in losses and management methods of plant diseases. 
Plant pathology can also be defined as the study of the nature, cause and prevention of plant diseases. Plant pathology is related to most of the old and new sciences like biology, physics, chemistry, physiology, mathematics, genetics, soil science, biochemistry, biotechnology etc.

Objectives of Plant Pathology
The key objectives of plant pathology include:
1. Understanding Disease Etiology: Identifying the causal organisms or factors responsible for plant diseases.
2. Disease Diagnosis: Developing tools and techniques for early diagnosis of plant diseases.
3. Pathogenesis: Studying how pathogens cause disease in plants and how plants respond to infection.
4. Disease Management: Creating effective and sustainable strategies to control and prevent plant diseases.
Definition and Scope of Plant Pathology
Plant pathology, also known as phytopathology, is the study of plant diseases caused by pathogens (infectious agents) and environmental conditions (non-infectious agents). It encompasses the diagnosis of plant diseases, the mechanisms of disease development, and the development of management strategies. A widely accepted definition of plant pathology is provided by George N. Agrios (2005), who defined it as:
“Plant pathology is the study of the living entities and environmental conditions that cause diseases in plants, the mechanisms by which they induce disease in plants, the interactions between the plant and the pathogen, and the methods of preventing or managing plant diseases.”
Plant pathology integrates principles from microbiology, botany, mycology, bacteriology, virology, and genetics to address plant health issues. It is a critical field for ensuring food security, agricultural sustainability, and the stability of ecosystems

WHAT IS PLANT?

A. Definition - by most definitions, a plant:

is multi-cellular;

is non-motile

has eukaryotic cells

has cell walls comprised of cellulose

is autotrophic; and

exhibits alternation of generations - has a distinctive diploid (sporophyte) and haploid (gametophyte) phase.

History of poultry production

Domestication of birds has a long history, with evidence of their existence and use dating back thousands of years. Here are some key points:

• Chickens: Archaeological evidence suggests domesticated chickens existed in China 8,000 years ago and later spread to Western Europe, possibly via Russia. The cockfighting in India 3,000 years ago indicates their cultural significance. Modern domestic chickens (Gallus domesticus) evolved from the wild red jungle fowl (Gallus gallus), native to India and Southeast Asia.

• Pigeons: The domestic pigeon (Columba livia f. domestica) is considered the world’s oldest domesticated bird.

• Geese: Domestic geese (Anseranserdomesticus in Africa, Europe, and West Asia; Ansercygnoides in East Asia) were domesticated in Egypt over 4,000 years ago and have significance in Roman mythology.
