Policy research plays a critical role in influencing policy change by generating robust evidence that can guide decision-making processes. The use of evidence is crucial in ensuring that policies are both effective and appropriate to address specific issues. Evidence-based policy-making relies on credible, relevant and timely research that helps identify problems, evaluate potential solutions and
forecast the impacts of various policy options.
Role of Policy Research in Generating Evidence
1. Identification of issues: Policy research begins with identifying key issues or challenges that require policy intervention. This involves conducting systematic research to understand the scope, scale and
nature of the problem. For example, research on gender disparities in agricultural labor in India may highlight specific barriers women face, such as lack of access to resources or discriminatory practices.
2. Data collection and analysis: Gathering quantitative and qualitative data is essential for building a comprehensive understanding of the issue. For instance, data collection may involve surveys, interviews,
case studies and secondary data analysis to capture diverse perspectives and experiences. This data provides a solid foundation for analyzing the problem’s root causes and identifying the affected population.

The policy development process is a structured approach to creating policies that address specific issues or achieve particular goals. It involves several steps, from identifying the problem to implementing and evaluating the policy
Steps of Policy Development Process
1. Problem identification
• Definition: The process of recognizing and defining an issue that requires government intervention.
• Key actors
• Public: Citizens, interest groups and communities often raise awareness about problems.
• Media: Plays a critical role in highlighting issues and shaping public opinion.
• Policymakers: Government officials, legislators and public administrators who prioritize issues.
• Experts and academics: Provide data, research and analysis that help frame problems.

It is a systematic method to solving problems through an examination of policy approaches.
It involves evaluating public policies, including their development, implementation and impacts, to determine their effectiveness in achieving desired outcomes. The process includes identifying relevant issues, assessing potential solutions, weighing the costs and benefits and recommending the most appropriate course of action.
Use of Policy Analysis in Decision-Making
Policy analysis combines qualitative and quantitative methods to assess policies’ implications on economic, social and political factors. It often includes stakeholder analysis, forecasting future scenarios and evaluating policy impacts using tools like cost-benefit analysis, risk assessment and statistical modeling

Introduction
The word “Advocacy” is defined as any action that promotes, urges, justifies defends, or pleads on behalf of another person is referred to as advocacy. In all its manifestations, advocacy works to make sure that people, especially those who are most sure people, especially those who are most at risk in a group or society can:
• Have their opinions taken into account when decisions about their lives are being made
• Speak up for matters that are important to them.
• Defend and protect their rights
• Have their voice heard on key subjects.

Importance of Policies for Extension
Policies play an important role in the field of extension, which involves the transfer of knowledge and technology from researcher to farmers, communities and other stakeholders. Following are some specific reasons why policies are vital for extension:
1. Accountability: Policies may provide basis for monitoring and evaluation of extension activities and for holding extension professionals and other stakeholders accountable for their actions.
2. Innovation: Policies can promote innovation in extension by encouraging the adoption of new technology, approaches and practices, encouraging experimentation, collaboration and continuous improvement. By removing barriers to adoption and offering rewards for testing, policies can also aid in the creation of an atmosphere that fosters innovation.
3. Consistency: Policies aid in ensuring that extension activities are consistent with the goals and objectives of organization or program. It offers a framework for decision-making that enables the uniform
handling of similar circumstances.

Introduction
Environmental Impact Assessment (EIA) is a process of evaluating the likely environmental impacts of a proposed project or development, taking into account inter-related socio-economic, cultural and human-health impacts, both beneficial and adverse.
UNEP defines Environmental Impact Assessment (EIA) as a tool used to identify the environmental, social and economic impacts of a project prior to decision-making. It aims to predict environmental impacts at an early stage in project planning and design, find ways and means to reduce adverse impacts, shape projects to suit the local environment and present the predictions and
options to decision-makers.
Environment Impact Assessment in India is statutorily backed by the Environment Protection Act, 1986 which contains various provisions on EIA methodology and process.
Evolution & History of EIA
EIA is termed as one of the best policy innovations in the 1900s. The main aim of EIA is to conserve the environment and bring out the best combination of economic and environmental costs and benefits. Read the below-mentioned points to understand the Environmental Impact Assessment evolution and history:
• The birth of EIA is dated back to the 1970s.

Impact assessment approaches
Impact assessment approaches can be classified into four broad categories i.e. quantitative, qualitative, participatory and mixed methods.
i. Quantitative impact assessment approaches
• It focuses on assessing the degree and extent of the impacts quantitatively.
• Some degree of quantification may be necessary in all impact assessments, in order to evaluate the success of the Intervention and the extent of any adverse effects.
• Largely depends on micro-economic approaches following econometric models
• Involving baseline studies: The precise identification of baseline conditions, definition of objectives, target setting, rigorous performance evaluation and outcome measurement
• Costly and limited scope: Limited in the types of impacts which can be accurately measured and may pose difficulties for inference of cause and effect.

Indicators for impact assessment
Meaning and concept of Indicator
The term indicator is often used interchangeably with data, targets, standards for evaluation, and even various modes of data collection, which undoubtedly inhibits a productive dialog on the subject. Such confusion is unwarranted, since the term has a precise connotation- in the literature on monitoring and evaluation of development. Simply stated, indicators are variables designed to measure change in a given phenomenon or process. They are analytical tools which facilitate the measurement of change and provide summary data for project design, implementation, and evaluation. Indicators are defined as
“specific (explicit) and objectively verifiable measures of changes or results produced by an activity or intervention” (United Nations: 1985; p. 37). A few observations about indicators can be useful in further clarifying their nature. First, as the above definition implies, indicators provide quantitative data which can be analyzed using statistical techniques to produce estimates of a phenomenon. In cases when only qualitative information is gathered, it should be converted into numerical data for the purposes of analysis and presentation. Second, an indicator can capture one or more dimensions of a phenomenon or process depending upon the purpose of the study. We can, for example, construct an indicator for urbanization based on a wide range of variables such as number of school, higher educational institution, road connectivity, number of financial institution, health infrastructure, income etc. On the other hand, one can use each of the above items as a distinct indicator. Indicators focusing on different dimensions of a subject are difficult and more costly to construct. Third, several indicators can be used to capture the same phenomenon.

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 to LFA – Background and description
The Logical Framework Approach (LFA) is a methodology mainly used for designing, monitoring, and evaluating international development projects. Variations of this tool are known as Goal Oriented Project Planning (GOPP) or Objectives Oriented Project Planning (OOPP). The logical framework Approach is a method to develop the project’s goals and activities and identify key information (such as risks) through a participatory approach. Basically, this means that instead of having a single person who designs the project all on his own, you seek the involvement of all concerned parties – also known as the stakeholders. The most important stakeholders are the potential beneficiaries of the project, or the target group.Getting the involvement of your target group and other stakeholders not only ensures that your project is well designed. It also makes sure that everybody is aware of the project and what it is supposed to change. It allows people to get involved, and develop a feeling of responsibility for the project and its results.This is known as developing ownership for the project’s outcomes, and it is important to make sure that the positive realizations of the project are embedded locally and durable over time. People will care about the project and take care about its results.

An important decision that the management has to take during implementation of the process of evaluation is about which model to choose. The choice of a single model will mainly depend on the nature of the problem or the situation in an organization. However an integrative approach using more than one model may also be used. Before implementation of any of these models and before the actual process of evaluation starts it is important to make suitable preparations and create a conducive environment in the organization for successful conductance of the evaluation. The following points are to be taken
in to consideration before and at the time an evaluation is carried out in an organization:

Networks – Introduction, origin and widely used networks
Network is a technique used for planning and scheduling of large projects in the fields of construction, maintenance, fabrication, purchasing, computer system instantiation, research and development planning etc. There is multitude of operations research situations that can be modelled and solved as network. Some recent surveys reports that as much as 70% of the real-world mathematical programming problems can be represented by network related models. Network analysis is known by many names PERT (Programme Evaluation and Review Technique), CPM (Critical Path Method), PEP (Programme Evaluation Procedure), LCES (Least Cost Estimating and Scheduling), SCANS (Scheduling and Control by Automated Network System), etc.
It is a graphical representation of logical and sequentially connected activities and events of a project. Network is also called arrow diagram. PERT (Programme Evolution Review Technique) and (Critical Path Method) are the two most widely applied techniques.

SWOT Analysis – Concept, origin and evolution
While working on a research project at the Stanford University sometime around 1960s to 1970s, Albert Humphrey developed an analytical tool to evaluate the strategic plans and find out why corporate planning failed. He coined this technique as SOFT analysis where –
• S stood for what things are Satisfactory at present,
• O denoted what Opportunities can be explored in the future,
• F meant the Faults in the present and
• T signified the Threats that could surface in the future.
While the majority agrees that SOFT is the predecessor of SWOT, some people believe that the concept of SWOT analysis emerged separately and has nothing to do with SOFT.
How SWOT evolved from SOFT?
The first mention of the term SWOT can be traced back to the Long Range Planning seminar held in Zurich in 1964. In this seminar Urick and Orr proposed the concept of SWOT analysis which was derived from SOFT by replacing the F for faults with W for Weaknesses. With its initial promotion in the Britain, the concept soon gained recognition among strategic planners and management consultants the world over. The new interpretation of SWOT, the way it is used these days, differs slightly from that of SOFT.

Ten Steps in programme evaluation
i. Identify and describe programme you want to evaluate: The first step of the evaluation process is to identify the object or programme of evaluation. For this purpose, a short written description of the object or programme to be evaluated must be drafted. This description must be formulated in a way that is also comprehensible to outsiders. Relevant items to be included in this description are, for example, the name of the object or programme of evaluation, the expert responsible for it, the employees taking part in it, the goals, scientific references, the contents or topics, the elements, methods, scope, available resources, key figures, past developments, etc.
ii. Identify the phase of the programme
• Design
• Start-up
• Ongoing
• Wrap-up
• Follow-up

Evaluation theories refer to the conceptual frameworks, models, and principles that guide the systematic assessment and analysis of programs, policies, interventions, and other social phenomena. They provide a set of organizing principles and methodologies for evaluating the effectiveness, efficiency, relevance, and sustainability of various interventions and initiatives in different domains, including education, healthcare, social services, environmental protection, and public policy. Evaluation theories draw from various disciplines, such as psychology, sociology, economics, statistics, and management, and they may emphasize different aspects of the evaluation process, such as the role of stakeholders, the criteria for success, the methods for data collection and analysis, and the use of evaluation results.
i. Programme theory
Program theory defines as the mechanisms that mediate between the delivery (and receipt) of the program and the emergence of the outcomes of interest. Programme theory, variously referred to as programme theory, programme logic, theory-based evaluation or theory of change, theory-driven evaluation, theory-of-action, intervention logic, impact pathway analysis, and programme theory-driven evaluation science refers to a variety of ways of developing a causal modal linking programme inputs and activities to a chain of intended or observed outcomes, and then using this model to guide the
evaluation. The term ‘logic model’ is used to refer to the summarized theory of how the intervention works (usually in diagrammatic form) and ‘programme theory evaluation’ is used for the process of developing a logic model and using this in some way in an evaluation. Most approaches to building logic models have focused on simple, linear models, but some have explored how non-linear models might be used to better represent programmes and guide their evaluation. In particular, a number of evaluators have incorporated concepts of complexity in their discussion and use of logic models. 

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.

Abstract
Ocean acidification, caused by rising atmospheric CO2, is a major environmental issue that threatens marine ecosystems and human livelihoods. This process decreases the pH of seawater, increasing its acidity, through a series of chemical reactions that result in the formation of carbonic acid. These changes negatively impact marine food webs, especially calcifying organisms like corals, molluscs, and plankton, which depend on carbonate ions to build their shells and skeletons. The cascading impacts of acidification jeopardize the biodiversity, productivity, and resilience of marine ecosystems, including fisheries that millions depend on for food and income. Factors such as ocean warming, deforestation, and natural CO2 emissions exacerbate acidification. Mitigation efforts, including reducing CO2 emissions, restoring habitats, and promoting sustainable fishery management, are essential for minimizing future impacts. Addressing and mitigating ocean acidification are critical for conserving marine life, sustaining fisheries, and preserving ecological balance in the face of global climate change.

Abstract
Climate change is a significant threat to global fisheries, affecting the livelihoods of approximately 39 million people engaged in fishing. This chapter discusses the challenges fishermen face due to climate change, ranging from environmental to social and economic issues. Rising sea levels, warmer ocean temperatures, and unpredictable weather patterns disrupt fish populations and traditional fishing methods, resulting in severe socio-economic difficulties for coastal communities. Trends concerning marine heatwaves have doubled since 1982, while ocean acidification is on the rise; these trends form a complex set of problems for fishers. Besides changing fish distribution, it causes damage to essential habitats and, thereby, further endangers marine biodiversity. Economic impacts include reduced catches and increased operational costs, combined with market fluctuations that can threaten their financial stability. Socially, the effect of climate change increases health and safety risks and creates mental health problems due to economic instability. Traditional fishing knowledge is becoming less relevant because fishermen must adapt to new circumstances. The chapter strongly emphasizes the need to develop adaptive strategies involving community-led and government-supported programs that strengthen the ability of fishing communities to build resilience. Fishermen can benefit by changing the marine resource landscape through a greater focus on more resilient species and modifications in practice. Finally, the chapter concludes by arguing for a holistic approach to address these interconnected challenges to ensure the
sustainability of fisheries and the livelihoods of those who depend on them in the face of ongoing climate change impacts.

Abstract
Mangroves are vital ecosystems that maintain biodiversity, protect coastal areas, and sequester carbon. However, unsustainable aquaculture techniques, notably shrimp farming, are under considerable threat to these essential habitats, contributing to widespread mangrove destruction. The consequent environmental damage highlights the critical need for sustainable aquaculture practices. Aquasilviculture, or silvofishery, is a novel concept that combines aquaculture and mangrove protection. This approach combines shrimp or fish farming with mangrove planting and management, which promotes ecological restoration while preserving aquaculture productivity. Mangroves serve as natural filters, improving water quality by absorbing organic and chemical contaminants, while their organic content enriches pond habitats and promotes the growth of aquatic animals. Successful aquasilviculture schemes, such as Indonesia’s empang parit system and integrated mangrove-aquaculture farms in Vietnam and Bangladesh, illustrate the ability to resolve economic and environmental goals. These approaches increase aquaculture yields, protect biodiversity, and give socioeconomic advantages to local populations. Despite its potential, aquasilviculture confronts obstacles, including financial and technological impediments to implementation. Supportive policies, capacity building, and research are critical for expanding this approach.

Abstract
Coastal wetlands, including mangroves, salt marshes, and seagrass meadows, play a critical role in regulating the global climate by sequestering carbon. These ecosystems act as vital carbon sinks, efficiently absorbing and storing carbon in their biomass and soils. Despite covering only 2-3% of the planet’s surface, coastal wetlands are believed to store more than half of the world’s carbon in the top meter of soil, helping to mitigate climate change. The unique hydrological and biological characteristics of these ecosystems, such as their ability to slow the decomposition of organic matter and facilitate sediment burial, are crucial to their carbon storage capacity.
In addition to their role in carbon sequestration, coastal wetlands provide essential ecological services, including supporting biodiversity, preventing erosion, and protecting against storm surges. However, they face significant threats from pollution, climate change, human activity, and hydrological alterations, which could jeopardize their ability to store carbon. Preserving and restoring coastal wetlands is essential for maintaining their carbon sequestration capacity and strengthening climate resilience. Effective wetland conservation efforts, including sustainable land-use practices and restoration techniques like sediment augmentation, are essential to ensure these vital ecosystems continue to contribute to climate regulation.

Abstract
The growing need for sustainable fishing practices has increased attention to eco-friendly fishing technologies designed to minimize their environmental impact. These technologies focus primarily on reducing habitat destruction, bycatch and overfishing, which is essential for maintaining a balanced marine ecosystem. Traditional fishing methods such as bottom trawling and non-selective fishing practices have caused notable harm to the ecosystem, including the destruction of seabeds and accidental catches of non-targeted fish populations. Advancements in eco-friendly designs, such as turtle-excluding devices (TEDs) and bycatch reduction devices (BRDs), have crucially mitigated the bycatch of vulnerable species such as turtles and juvenile fish. Modifications in longlines, traps, and biodegradable nets have further reduced ecological damage. In addition, electronic innovations such as sound navigation and ranging (SONAR) system and Global Positioning System (GPS) enable precise fish targeting, reducing unwanted habitat damage. However, the transformation to eco-friendly technologies faces issues such as investments, lack of awareness and inadequate regulatory support. Government and international bodies play a vital role in promoting these technologies through various regulatory policies and frameworks. Further, fostering cooperation among the stakeholders and using innovations can ensure a future of sustainable fisheries, balancing ecosystem conservation with economic livelihoods.

Abstract
Fish, a vital source of nutrition globally, faces challenges in maintaining microbiological safety and sensory quality due to its perishable nature. While effective in microbial reduction, traditional thermal processing methods often compromise fish’s nutritional and sensory attributes. In response, non-thermal technologies such as High Pressure Processing (HPP), Ultrasound (US), Ozone, and Pulsed Light (PL) have emerged as promising alternatives. These technologies offer effective microbial control while preserving the sensory and nutritional integrity of fish products. Ultrasound processing, has shown efficacy in microbial inactivation and quality enhancement without significant thermal impact. Studies on oily and white fish varieties demonstrate its capability to reduce microbial load while enhancing specific sensory attributes. In the same way, Ozone, which is known for its durable oxidative qualities, is useful in eliminating a wide range of bacteria on fish surfaces, although it must be taken into account when considering penetration depth and any sensory effects. Pulsed Light (PL) has shown quick microbial inactivation on fish surfaces and packaging materials by using high-intensity, short-duration pulses over a wide spectrum. High Pressure Processing (HPP) has become a reliable technique for increasing shelf life and guaranteeing microbiological safety in a variety of fish species. It works at moderate temperatures and high pressures. This chapter reviews the principles, applications, strengths, and limitations of these advanced non-thermal techniques in fish processing. It highlights their
potential to revolutionize the industry by meeting consumer demands for safe, high-quality fish products while overcoming the drawbacks associated with conventional thermal methods.

Nanotechnology
Nanotechnology is the study and manipulation of matter at the nanoscale, where unique phenomena allow for novel applications. Nanotechnology is the utilization of components smaller than 100 nanometers for manufacturing and bio-fabrication. This adaptable technique had a wide range of uses, from clothing manufacture to medical advancements such as cancer detection and treatment, among others. The name “nano” comes from Greek, which meaning incredibly small, and a nanometer (nm) is equal to 10 -9 m. Nanotechnology, also called as Molecular Manufacturing based Nanotechnology (MNT) as it involves experimentation and manipulating of nano particles, in order to design and build materials and devices with the basic structure in the nanometer scale. Nano material which can exist in the form of powder or liquid, exhibits significantly different physical and chemical properties at nanoscales compared to their micro size materials with similar chemical composition. Nano food refers to food in nanoparticles, nanotechnology techniques or tools are used during cultivation, production, processing, or packaging of the food.
The development of both organic and inorganic materials achieved through conversion and manipulation of the materials on an atomic and molecular scale [Grumezescu et al., 2018; Dera & Teseme, 2020]. By reducing the particle size below its outset to approximately 1–100 nm, the physical and chemical properties of the materials significantly differed when compared to the original materials despite they contain the same base materials. The unique
and incomparable properties of nanoscale materials are arise due to their high surface area-to-volume ratio compared to the microscale of the same materials [Grumezescu et al., 2018, Berekaa, 2015].

Abstract
The growing demand for fish products, recognized for their nutritional composition and contribution to a healthy diet, has led to a significant increase in seafood processing waste, including shells, bones, skins, and other by-products. This chapter explores the potential of utilizing these seafood by-products to develop edible films and coatings, aligning with circular bio economy principles of, resource efficiency, sustainability and waste reduction. Edible films and coatings derived from seafood waste, such as chitosan, proteins, gelatin etc. offer various advantages, which include extention of the shelf life of products, preserving sensory qualities (aroma, taste, and appearance), and reducing the need for synthetic packaging materials. These biodegradable films also demonstrate antimicrobial, antioxidant, and mould-inhibiting properties, which contribute to improving food quality and safety. However, despite the benefits, challenges remain in terms of the physical properties of these films, including water resistance, mechanical strength, and consumer acceptance. The commercial application of these biopolymer-based materials is still limited by these issues, as well as by the complexities involved in scaling up production processes. To optimise the qualities of edible films and coatings made from seafood waste, more research is essential, particularly through the development of composite materials and innovative gelling systems. With ongoing advancements in biopolymer technology and processing techniques, edible films from seafood waste hold great promise as a sustainable, eco-friendly alternative to traditional plastic packaging, contributing to the circular bio economy and reducing environmental pollution.

Keywords: Marine Protected areas, Ecosystem, Protection and International
Distribution of Marine Protected Areas
There are 8.06% marine protected areas (MPAs) in the world. The Global Ocean can be divided into areas within national jurisdiction (National Waters) and those in international waters (Areas Beyond National Jurisdiction (ABNJ)). Governments in national waters with established legislative frameworks find it easier to establish MPAs. MPA creation is more challenging in ABNJ because of the intricate legislative system that governs the state.
As a result, compared to ABNJ, a significantly larger number of MPAs have been established within national waters. 39% of the world’s ocean is made up of national waters, of which 18.43% are currently protected areas.

Abstract
Food webs are essential for understanding ecological interactions, and the discovery of trophic cascades marks a significant milestone in food-web ecology. Over the past four decades, debates on the prevalence and importance of trophic cascades have spurred extensive research and theoretical progress, yet the topic remains contentious. Trophic cascades, where alterations in one part of the ecosystem affect others, play a crucial role in shaping ecosystem structure and function. Rooted in foundational theories like the Green World Hypothesis, the concept has evolved to address more intricate ecological dynamics. Cascades often occur through top-down and bottom-up mechanisms, with top predators playing a key role in regulating ecosystems. This article explores their diverse impacts in aquatic environments, including changes in food web dynamics, biodiversity loss, water quality degradation, and disrupted nutrient cycling. Case studies, such as the otter–sea urchin–kelp system and Atlantic cod overfishing, highlight the profound consequences of these interactions. The findings underscore the importance of maintaining balanced trophic relationships to ensure ecosystem stability and resilience. Conservation efforts should focus on maintaining these dynamics to mitigate cascading effects and preserve biodiversity and ecosystem services.

Abstract
The development of aquaculture from its prehistoric beginnings to a highly developed, international sector emphasizes the need for cutting-edge equipment to guarantee sustained production. Passive Integrated Transponder (PIT) tagging is a cornerstone for selective breeding programs, enabling precise monitoring and managing aquatic species. PIT tags, tiny electronic microchips implanted into fish, offer a reliable and durable method for individual identification without affecting species growth or survival. Their versatility extends across various applications, from studying migration and behaviour to monitoring genetic traits critical for breeding. PIT tagging stands out due to its simplicity, cost-effectiveness, and compatibility with various aquatic environments. PIT tags offer a long-term solution with less interference than external tags, which are more likely to be lost or damaged. Technological advancements have refined PIT tagging, allowing its application even in small-bodied fish, thus broadening its utility in ecological and genetic studies. These tags also play a pivotal role in reducing inbreeding in hatcheries by maintaining precise genetic records. Despite the proven benefits, PIT tagging requires careful consideration of fish species, size, and environmental factors to optimize tag retention and ensure minimal stress. Advancements in tagging techniques, such as improved surgical techniques and new equipment for tag implantation further increase the dependability of this technology. Studies confirm that PIT tagging has negligible effects on fish physiology and behaviour, making it an indispensable tool in aquaculture research and management. The aquaculture sector can enhance broodstock quality, guarantee genetic diversity, and tackle climate change issues by incorporating PIT tagging into selective breeding strategies. This technology not only supports the production of high-quality seed stock but also aligns
with sustainable aquaculture practices, ensuring the long-term viability and growth of the industry.

Abstract
Single-cell proteins (SCPs) have gained huge attention in the aquafeed industry as a suitable alternative to traditional protein sources, including fish meal and soy protein. SCPs obtained from the algae, bacteria, fungi, and yeast often contain high protein content and superior amino acid profiles. The presence of essential fatty acids and additional bioactive compounds further support their role as adequate replacements for the current protein sources. Among those, mycoproteins are currently a major area of interest due to their favourable nutritional profile, higher growth rates and efficient production process. These have the ability to use a variety of agricultural and industrial by-products as their feedstocks. PEKILO® protein is such a commercial mycoprotein obtained from carbohydrates containing lignocellulosic wastes from forestry by-products. It was produced from the fungal species Paecilomyces variotii from the substrates such as spent sulphite liquor and molasses through a continuous fermentation process. Pekilo protein consists of 60 to 70% crude protein content, essential amino acids, vitamins, minerals, β-glucans and nucleotides. Its high digestibility and amino acid content make it a suitable protein source for the aquafeed industry. Recent research studies suggest that pekilo protein has a high potential as a non-conventional protein source in commercial salmon and shrimp feeds. Being a sustainable alternative to fishmeal, pekilo protein can help reduce the future challenges of fish meal supply and long-term sustainability.

Abstract
Aquaculture is the fastest-growing food production sector globally, with finfish and crustaceans playing a significant role in meeting the growing demand for animal protein. However, aquaculture’s reliance on marine capture fisheries for essential feed ingredients, such as fishmeal and fish oil, presents significant sustainability challenges. The Fish In: Fish Out (FIFO) ratio, which estimates the quantity of wild-caught fish used to generate one unit of reared fish, has become a key metric in assessing the sustainability of aquaculture. A high FIFO ratio indicates greater dependence on wild fish stocks, contributing to overfishing and ecosystem degradation. This chapter explores the FIFO ratio, its role in promoting sustainable aquaculture, and innovations to reduce its environmental impact. Over the years, the global average FIFO ratio has improved, reflecting advances in feed efficiency and the incorporation of alternative ingredients such as plant-based proteins, insect meals, and by-products from fish processing. However, challenges remain in these alternatives’ availability, cost, and nutritional performance. Case studies, including salmon rearing in Scotland and shrimp farming in Thailand, demonstrate the potential of alternative feed ingredients in lowering FIFO ratios and enhancing sustainability. This chapter also addresses the limitations of the FIFO ratio as a singular sustainability metric, calling for a more holistic approach to evaluating aquaculture’s environmental and economic impacts. Ultimately, achieving sustainable FIFO ratios will require
continued innovation, improved feed formulations, and global collaboration to ensure aquaculture’s role in providing a sustainable source of protein for the growing global population.

Medicinal Plants for Arsenic Toxicity
Name of the Condition- Nephrotoxicity
About the condition/Definition- Intoxication of arsenic (arsenite or arsenate) result in renal impairment which is marked by a significant increase in the levels of creatinine, urea, uric acid and decline in levels of plasma protein profile especially albumin level in body.
Etiology- Nephrotoxicity results from arsenic damages mitochondria, which results in the excessive production of reactive oxygen species (ROS), a decline in ATP, and a suppression of respiratory activities along with dramatic alterations in the incidence of cellular growth. There is acute inflammation and the development of tubular necrosis, which lowers the glomerular filtration rate (GFR).
Symptoms- Phosphaturia (Fanconi syndrome), aminoaciduria, proteinuria and glycosuria along with progressive drop of renal function.
Pathogenesis- Arsenic produces renal damage by reducing mitochondrial complex function and elevating cellular ROS levels which directly damages renal cells. Membrane lipid peroxidation and protein oxidation by ROS, which results in complete loss of membrane potential and mitochondrial swelling.
General treatment- Acute arsenic intoxication can be counter by using chelating agents like DMSA, DMPS and BAL, fluid therapy, forced dieresis & dialysis.

Wound in Domestic Animals
A wound is defined as a break in the continuity of the skin, mucous membrane, or tissue surface that can result from physical, chemical, or biological agents. India has a diverse variety of livestock breeds, extensive countryside with vast grazing lands, and widespread use of livestock. The significant population of stray animals, including dogs, cats, and cattle, as well as the increase in pet ownership, make wounds in animals a commonly encountered condition. Wounds in animals can be a frustrating issue for both pets and productive animals, and this can also be a challenge for their owners. For instance, bleeding at the wound site from sudden cuts and bites can cause panic and distress among animal owners. Wounds can become complicated, as animals may lick, scratch, or otherwise irritate them, leading to infections, especially when they are soiled. Additionally, fly infestation and maggots, common in various temperate regions of India, further complicate the wound healing process. An unattended wound can quickly escalate to a severe microbial infection, which may lead to septicemia, maggot infestation, and can even become fatal for the animal. The cost of treating wounds in production animals, including expenses for antibiotics, can impose an economic burden on farmers. Common causes of wounds in domestic animals include penetrating injuries from horns, stamping injuries caused by mothers or other adult animals in tightly packed barns, tightened nose ropes, barbed wire injuries at the brisket region (in horses and cattle), and wet sores on the inner surfaces of the shoulder and groin in cattle due to friction and lack of air and sunlight exposure.

Feed additives like antibiotics, hormones are successfully employed in chicken production along with basic minerals, vitamins, and nutrients. Because of worries about antibiotic residues in animal tissues and the resulting development of bacterial resistance, the use of antibiotics as growth promoters (AGP) in cattle was outlawed in 2005. Given the rising concerns about antibiotic use and its involvement in antibiotic resistance, the use of plant-based chemicals in animal feed has become essential. Phytogenic feed additives, which are made from plants and their secondary metabolites, are becoming more and more popular as a result of the search for sustainable farming methods.
These natural growth promoters are seen as alternatives to synthetic chemicals, which are often associated with adverse environmental and health impacts. The usage of plant additions, also known as phytobiotics, have existed since the beginning of time, when people and farm animals were treated and prevented with herbs. The unique qualities of herbs and plant additions were effectively utilised by the ancient Greek, Egyptian, Roman, and Chinese civilisations. Phytogenic feed additives offer multiple benefits for livestock, including enhancing growth, improving immunity, supporting digestion, and promoting
overall animal health. Water or alcohol extracts derived from plant additions, whether fresh or dried, fermented, or freeze-dried, can be used in poultry practices.
