This illuminating book incisively surveys the complex legal regime of access and benefit-sharing in key aquaculture countries. With an international focus spanning countries across Africa, Asia, Europe and South America, the authors explore the application of international legal standards and how these translate into domestic measures.Presenting key critical perspectives, the book examines the ways in which access and benefit-sharing laws facilitate access to aquaculture resources and how they could, in return, deliver a fair and equitable share of the benefits, promoting conservation and longer term food security. The authors'in-depth analysis of various case studies reveals that these legal standards rarely accommodate the distinctive features of aquatic genetic resources, digital sequence information and traditional knowledge. They argue that the access and benefit-sharing concept is not fit for purpose and suggest how the concept could be re-imagined to achieve more efficient outcomes for conservation, sustainability, fairness and equity.Access and Benefit-sharing in Global Aquaculture is a fundamental resource for academics, researchers and students of environmental law and governance, environmental politics and policy, management, and regulation. Policymakers working with the aquaculture industry will similarly benefit from the authors'practical recommendations.

According to FAO's (1989) proposal, aquaculture is the cultivation of aquatic organisms, such as fish, crustaceans, mollusks, and aquatic plants. Traditional stocking, feeding, and safety from predators, among other factors, are all aspects of farming widely used to boost production. Additionally, farming implies individual or corporate tenure of the farmed stock. Aquatic organisms that are exploited by people as a shared property resource with or without proper licensing are the fisheries harvest, whereas aquatic organisms that are reaped by personal or corporate bodies that owned them during their rearing duration contribute to aquaculture for statistical purposes. The utilization of living aquatic resources in a continuous system from capture to culture is what this volume on aquaculture is all about. The relationship between aquaculture, agriculture, and fisheries is examined in light of its fundamentals and potential. Aquaculture has always made use of entrenched ideas, methods, and technologies from the cultivation of terrestrial florae and faunae. Agriculture, aquaculture, and fishing all end up producing final products that compete with one another or complement one another, make use of similar technologies for processing, conservation, or marketing, and call for the same type of research. In specific chapters, the volume provides in-depth descriptions of the general principles and originality of aquaculture art.

World population is growing exponentially with increasing demand in food security. Aquaculture is one of the fastest-growing, food-producing sectors accounting for nearly 50% of the world's fish production. Aquaculture is culture of aquatic plants and animals in aquatic environment. Last few decades, aquaculture is becoming more reliable, efficient and sustainable source of high quality food production. Though, its major goal is to produce aquatic food for human consumption, but also has other goals, such as ornamental and sport fish cultivation. It also reduces stress on capture fishery which under threat due to over-fishing, habitat loss or other changes due to possible pollutants they have consumed or been exposed. However, aquaculture technology is continuously advancing through technological innovation to maximise yield/ha with less inputs and impact on environment. The farming of aquatic animals in controlled environment such as tanks, ponds or RAS in indoor premises is known as indoor fish farming. Indoor fish farming is one of the source of animal protein production to this day, especially in locations far from the sea. It allows fish to be raised in a controlled and optimised environment with increased control on water quality, feeding and diseases monitoring. Though, it requires significant initial investment, planning and expertise to establish, but has more advantages over open culture. Moreover, it is possible in urban area or area where land and water scarcity. Optimal water quality for the good health and growth of cultured fish species is achieved through proper oxygenation, feeding, filtration and removal of waste products to get control on ammonia, nitrate and nitrite. It too offers potential benefits in terms of water conservation, reduced environmental impact, efficient resource utilization, optimal FCR and risk of fish escapement. This book scientifically focuses on advances, operation, economics, management as well as challenges and safety in indoor aquaculture along with its impact on human beings. This book also touches SSFs, capture fisheries and its subsequent management. This book potentially serves as a manual for interested aquaculturist, policy makers as well as students pursuing graduation, post-graduation and research studies.

Presently, there is significant research focused on the use of probiotics and prebiotics in fish and shellfish. These applications have shown various benefits, including improved health, growth performance, feed utilization, disease resistance, gastric morphology, enzyme activities, carcass composition, larval survival, and gene expression. Moreover, prebiotics and probiotics have the potential to mitigate stress responses, reduce malformations, and regulate blood cholesterol levels in aquatic animals. The book highlights the potential advantages of stimulating the inherent immune system, both locally and systemically. Several aquaculture production species, such as European sea bass, Salmonids, gilthead sea bream, African catfish, channel catfish, carp, tilapia, and shrimp, have demonstrated enhanced disease resistance against relevant pathogens, likely due to microbial modulation. This book explores the gut microbiota of aquatic creatures, studying methods and potential uses of probiotics and prebiotics in aquaculture. Controlling gut content significantly impacts the health, growth, and quality of farmed fish and crustaceans. The book covers the science behind using probiotics and prebiotics to improve overall well-being, growth rates, and feed utilization. It is a valuable resource for academics, researchers, and aquaculture specialists, providing insights into gut microbiota and its importance for fish health and performance.

India has made phenomenal progress in inland fisheries sector. Major inland fisheries resources of country comprise 1) capture fisheries of rivers, lakes and estuaries 2) culture fisheries of the ponds and tanks and 3) capture-cum-culture fisheries of reservoirs and oxbow lakes.

The book encompasses the extensive fish farming system which is the least managed form of fish farming, in which little care is taken. This system involves large ponds measuring 1 to 5 ha in area with stocking density limited to only less than 5000 fishes/ha. No supplemental feeding or fertilisation is provided. Fish depends only on natural foods. Yield is poor (500 to 2 ton/ha), and survival is low. The labour and investment costs are low, and this system results in minimum income. An intensive fish farming system is the well-managed form of fish farming, in which all attempts are made to achieve maximum production of fish from a minimum quantity of water. This system involves small ponds/tanks/raceways with very high stocking density (10-50 fish/m3 of water). Fish are fed wholly formulated feed. Proper management is undertaken to control water quality by use of aerators and nutrition by use of highly nutritious feed. The yield obtained ranges from 15 to 100 ton/ha or more. Although the cost of investment is high, the return from the yield of fish exceeds to ensure the profit. The financial management in the intensive and extensive fish farming must be monitored by the farmers to forecast the yields. This book provide an insight on mitigation measures to be planned in advanced to minimize the losses incurred due to uneven growth rates or natural calamities. This book provides an introduction to intensive and extensive fish farming and it can be used by the undergraduates, postgraduates and research students who wish to work in the fish farming sector.

The control of parasites in fish farms has traditionally involved the use of pesticides, either as bath treatments or by oral administration. The search for other ways to control the incidence of parasites is now being intensified to improve fish quality, safer final product, and lower environmental impact. The addition of cleaner organisms as biological control agents has broadened the perspective of rearing fish in a more environmentally friendly way. In the marine environment, the interspecific relationships between fish are ubiquitous and are commonly described as beneficial interactions where a smaller species (cleaners) remove parasites and infected tissue from the body surface, mouth, and gill chambers of other fish. Furthermore, in certain cases, the need to seek cleaning seems to go beyond the question of parasite removal; it is also about gaining physical contact and other health benefits. However, the inclusion of cleaner fishes to the farming system adds another organism to the production effort, whose biology is, in most cases, unknown to the industry. This raises another layer of challenges, not only in terms of rearing a novel species but also in terms of the welfare of the cleaners themselves. Therefore, this is a field that deserves further attention and research, to establish better welfare standards and lower disease outbreaks for farmed fish, both cleaners and clients. This book introduces important cleaner fishes that can reap benefits to the fish farming communities. The problems associated with freshwater aquaculture have been emphasized. The advancements in freshwater aquaculture and the present situation regarding the tools being used are explained. The impact of aquaculture on the environmental factors was explained in this book. The socio-economics of the cleaner fish aquaculture is explained in this book. This book serves as a handbook for the students across all the subject areas who are interested in either pursuing a career in aquaculture or research in similar fields.

Aquaculture exemplifies the ongoing global struggle to strike a sustainable balance between the conflicting needs of a rapidly increasing world population, human health, ecosystem health, the welfare of wild and domesticated animals, and the economic principles of globalized economies. On the one hand, aquaculture has great potential for providing us with a healthy and nutritious food supply whilst alleviating pressure on captive fisheries and reducing fisheries-induced habitat destruction, overfishing, genetic modification of wild populations, and wholesale waste of bycatch. On the other hand, aquaculture relies heavily on clean water, an increasingly precious (and dwindling) resource that is subject to intense pressure of being used for many competing objectives. This concise primer introduces students to the basic concepts, opportunities, and challenges of aquaculture with an emphasis on ecological considerations. It provides a critical assessment of current aquaculture practices from a broad, interdisciplinary perspective and from the standpoint of how best to align the two major (and often conflicting) goals of future aquaculture development: minimizing reliance on ecosystem services whilst maximizing productivity. A Primer of Ecological Aquaculture provides an accessible and authoritative overview for a wide range of undergraduate majors ranging from biology, engineering, and environmental policy to business and management. It will also appeal to a more general academic audience who wish to gain a current overview of the field.
