Book Description
Current growth in global aquaculture is paralleled by an equally significant increase in companies involved in aquafeed manufacture. Latest information has identified over 1,200 such companies, not including those organizations in production of a variety of other materials, i. e. , vitamins, minerals, and therapeutics, all used in varying degrees in proper feed formulation. Aquaculture industries raising particular economically valued species, i. e. , penaeid shrimps and salmonids, are making major demands on feed ingredients, while relatively new industries, such as til apia farming, portent a significant acceleration in demand for properly formulated aquafeeds by the end of the present decade and into the next century. As requirements for aquafeeds increases, shortages are anticipated in various ingredients, especially widely used proteinaceous resources such as fish meal. A variety of other proteinaceous commodities are being considered as partial or complete replacement for fish meal, especially use of plant protein sources such as soybean meal. In the past five years, vegetable protein meal production has increased 10% while fish meal production has dropped over 50%, since 1989, largely attributed to overfishing and serious decline in wild stock. Throughout fisheries processing industries, traditional concepts as "waste" have given way to more prudent approaches, emphasizing total by-product recovery. Feed costs are a major consideration in aquaculture where in some groups, i. e. , salmonids, high protein-containing feeds using quality fish meal, can account for as much as 40 to 60% of production costs.

Book Description
Examine the world's leading aquaculture producers! Sustainable Aquaculture: Global Perspectives is a one-of-a-kind primer on the world's leading sources of aquatic production, presenting expert commentary that includes the latest advancements, developments, and research findings. The book examines essential elements of aquaculture (water quality, nutrition, genetics, culture methods) and addresses problems such as over-fishing, coastal and wetland destruction, and habitat and environmental degradation. Sustainable Aquaculture: Global Perspectives addresses policy measures that are essential for the long-term sustainability of the world's fisheries—and the long-term employment of those who rely on the aquaculture industry for their livelihood. As the world's population increases at an alarming rate, the question of how to ensure global food security is one of extreme importance. But the world's total yield is below expectations and the book examines the reasons why: the under-utilization of natural resources, the lack of adoption of modern scientific methods, the lack of standardized, proven pond fertilization protocols; long-term inbreeding and the loss of genetic variability due to genetic drift. Sustainable Aquaculture: Global Perspectives also addresses: freshwater pearl culture breeding programs pond fertilization regimes fish diseases in tropical climates indoor recirculating culture systems water quality management for shrimp farming and much more! With much of its information available in one place for the first time, Sustainable Aquaculture: Global Perspectives is invaluable as a textbook for introductory aquaculture courses and is an essential resource for professionals and researchers.

Book Description
Aquaculture is the fastest-growing food production sector in the world. With demand for seafood increasing at astonishing rates, the optimization of production methods is vital. One of the primary restrictions to continued growth is the supply of juveniles from hatcheries. Addressing these constraints, Advances in aquaculture hatchery technology provides a comprehensive, systematic guide to the use of current and emerging technologies in enhancing hatchery production.Part one reviews reproduction and larval rearing. Aquaculture hatchery water supply and treatment systems, principles of finfish broodstock management, genome preservation, and varied aspects of nutrition and feeding are discussed in addition to larval health management and microbial management for bacterial pathogen control. Closing the life-cycle and overcoming challenges in hatchery production for selected invertebrate species are the focus of part two, and advances in hatchery technology for spiny lobsters, shrimp, blue mussel, sea cucumbers and cephalopods are all discussed. Part three concentrates on challenges and successes in closing the life-cycle and hatchery production for selected fish species, including tuna, striped catfish, meagre, and yellowtail kingfish. Finally, part four explores aquaculture hatcheries for conservation and education.With its distinguished editors and international team of expert contributors, Advances in aquaculture hatchery technology is an authoritative review of the field for hatchery operators, scientists, marine conservators and educators. - Provides a comprehensive guide to the use of technologies in enhancing hatchery production - Examines reproduction and larval rearing, including genetic improvement and microdiets - Discusses challenges in hatchery production of specific species

Book Description
A unique resource that describes the ingredients included in an aquaculture diet, species profiles, processing methods, impacts to environment and industry, and more. Aquaculture is and will remain a major food producing sector in the future. To become more efficient and successful in the aquaculture industry, operations need to provide good nutrition. Alternative Protein Sources in Aquaculture Diets is a unique source describing the ingredients included in fish and crustacean diets, their nutrient compositions, species profiles, suitability for species, processing methods, and impacts of alternative ingredients on the environment and to the aquaculture industry. World-renowned nutritionists and feed technologists explore practical ways for the aquaculture industry to expand and remain competitive, and discuss ways to develop less expensive alternative sources or protein. Diet costs take up a huge chunk of operating expenditures, with fish meal being one of the most expensive ingredients in the aquaculture diet. Alternative Protein Sources in Aquaculture Diets provides detailed knowledge on the use of alternative plant and animal protein sources, offering opportunities to either partially or completely replace fish meal. This comprehensive, up-to-date text discusses the most widely used ingredients as well as various previously under-utilized ingredients which could be of significant potential in the future. The book is extensively referenced and includes numerous helpful tables to clearly present data. Topics discussed in Alternative Protein Sources in Aquaculture Diets (for finfish and crustacean species) include: • farmed fish diet requirements • reduction of waste through diet formulation • poultry by-product meal • meat packing by-products • soybean protein foodstuffs • cottonseed meal • lupins • unconventional plant protein supplements.

Book Description
This book uses real-world examples from the aquaculture industry to demonstrate how deep technology is assisting farmers and vulnerable communities. Works conducted by Poseidon-AI (a deep tech company involved in the aquaculture sector) in different countries are presented as case studies to show the positive impacts of deep tech involvement in the aquaculture sector. Primary industries, such as fisheries and aquaculture, rely heavily on labor. Furthermore, the manual practices of these farming methods increase material waste and reduce yields, resulting in higher costs and lower revenues. Poikilotherms make up the majority of aquatic animals, and environmental changes have a significant impact on them. This means that, due to climate change, farming of these animals cannot continue in the same way that it has for centuries. Artificial intelligence, machine learning, image processing, sensing, and automation are approaches that can assist these farms in dealing with rapid environmental changes while also assisting farmers in growing their businesses sustainably. This book is of interest to climate change scientists, entrepreneurs, investors, civil workers, and policymakers. Furthermore, the book is a great complimentary material for graduate students of fisheries, aquaculture, ecology, soil science, water management and environmental sciences. All national and international policymakers working in implementation of UNSDGs and sustainability, will find this book a useful read.

Book Description
From green frogs and blue angels to white bunnies, modern consumers are confronted by a growing array of colorful eco-labels on everything from coffee to computers. When eco-labels are credible, they can lead to dramatic change in environmental practices broadly and quickly by leveraging the purchasing power of corporate clients (e.g., Walmart and McDonalds) to influence global supply chains. But the credibility of such labels is highly variable; and despite the existence of established practices for eco-labeling, many labels remain little more than superficial exercises in "greenwash." How can consumers separate greenwash from genuine attempts to address environmental challenges? Beyond Greenwash addresses this question by systematically investigating the credibility of transnational eco-labeling organizations across countries and commercial sectors. Using an innovative proxy measure for credibility that examines adherence to established best practices, Hamish van der Ven proposes a novel theory of rigor and credibility in transnational eco-labeling that upends conventional wisdom. He argues that the credibility of an eco-label does not depend on who creates or manages it-whether a government, industry association, professional standard setter, or environmental NGO. Rather, it depends on which types of businesses use the label. More specifically, eco-labeling organizations that target bigger, consumer-facing retailers tend to create credible eco-labels out of a desire to insulate their clients from critical scrutiny and gain acceptance in new markets. This theory challenges the conventional wisdom that only governments or environmental NGOs can create meaningful environmental governance and suggests that who is being governed matters as much, if not more, than who is doing the governing.
