In aquaculture, the provision of high quality aquafeeds that satisfy the nutritional requirements of the culture species and optimize growth are a prerequisite to improving production yields, lowering production costs, and improving economic returns to farmers. Under semi-intensive and intensive carp and trout culture, aquafeed costs usually account for the highest single production cost, typically accounting for 50 – 60 percent of total production costs. The aquafeeds available to farmers vary widely with respect to quality, nutritional value and cost. Depending on the feed type, production system and farmer preferences, there are multiple feed management strategies that can be adopted by farmers. In order to optimise feed use and minimise feed production costs, it is essential that farmers select appropriate feeds and optimise their on farm feed management practices. These guidelines are designed to provide farmers with practical guidance on how to select feeds and to optimise their use by implementing appropriate on-farm feed management practices. The guidelines provide an introduction to fish nutrition with a focus on the dietary nutritional requirements of commercially cultured carps and trout. The types of aquafeeds (live feeds, supplementary, farm-made and commercially manufactured feeds), their composition and nutritional value, manufacture and use are discussed. On-farm feed management practices focus on feeding methods, feed storage, and methods to optimise feed consumption (calculating feed rations, feeding frequency, assessing appetite and the feeding response).

Published in Cooperation with THE UNITED STATES AQUACULTURE SOCIETY As aquaculture production continues to grow and develop there is a continuous search for new species to culture to be able to fully exploit new national and international markets. Species selection for aquaculture development often poses an enormous challenge for decision makers who must decide which species and culture technologies to support with public resources, and then how best to divide those resources. Species and System Selection for Sustainable Aquaculture brings together contributions from international experts with experience in identifying potential species and production systems for sustainable aquaculture with a socioeconomic focus. The book is divided into three sections: Principles, Practices, and Species-Specific Public Policy for Sustainable Development. An outgrowth of a workshop held as part of the Aquaculture Interchange Program with examples from around the globe carefully edited by PingSun Leung, Pat O'Bryen, and Cheng-Sheng Lee this volume will be an important reference for all researchers, professionals, economists, and policy-makers involved in selecting new species for the development of sustainable aquaculture.

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.

This review reports on aquaculture development trends and challenges during 2000–2018 in the European Region covering 51 countries including European Union member states. Aquaculture production in the European Region is composed of marine molluscs and diadromous, marine and freshwater fish. It reached 3.4 million tonnes in 2018, while having a value of USD 16.6 billion. Atlantic salmon and rainbow trout combine to give nearly two million tonnes, with molluscs providing 0.7 million tonnes; marine fish species supplied 0.4 million tonnes and freshwater fish 0.3 million tonnes. In Europe, the strongest aquaculture growth has been seen in non-European Union states (e.g. Norway, Turkey, Russian Federation) while several European Union states have diminished production (e.g. France, Netherlands, Italy). The growth in value (5.8 percent) is higher than production (0.9 percent), which is now dominated by salmonids (nearly 60 percent), primarily Atlantic salmon. Mediterranean marine fish farming is mainly for gilthead seabream and European seabass. European cyprinid production in freshwater has increased slightly, where the Russian Federation, Czechia and Poland are the biggest producers. Mussels are the principal shellfish reared, led by Spain, followed by oysters in France and clams in Italy. While publicly quoted companies have led salmon development in Northern Europe, elsewhere aquaculture is done, with few exceptions, by SMEs and micro-enterprises. Mechanisms for financial support exist for aquaculture development throughout Europe but these have notnbeen matched by anticipated results. When unpredictable and time-consuming licensing procedures are combined with extreme competition for space and strict environmental regulations, both growth and investments are discouraged. Technology development focus has been given to structures appropriate for marine off-shore or ‘open ocean’ operation. The use of recirculating aquaculture systems (RAS) for large operations has also developed, both for hatcheries and for farms. Treatment for diseases and parasites remains problematic. Use of the same vaccines, veterinary treatments and disinfectants is not standardised, restricting the best health and welfare practices. Access to appropriate and efficient ingredients for formulated feeds remains a key issue for European fish farming, directly influencing productivity and profitability. The European Union is the world’s largest single market for seafood and the most important destination for European aquaculture production. With preferences declared for wild products vs. farmed, the habits of the European consumer have been studied, indicating evolving influences on purchase decisions. These include the use of additives, food miles, climate change, acceptance of manufacturing practices, cost and access as well as health benefits.

Fish have the same stress response and powers of nociception as mammals. Their behavioural responses to a variety of situations suggest a considerable ability for higher level neural processing – a level of consciousness equivalent perhaps to that attributed to mammals. Each chapter of this book has been written by specialists in their field. The subject matter is wide ranging and covers in detail concepts of animal welfare in addition to more specific aspects of fish welfare. Philosophical concepts of welfare are discussed along with more practical areas of fish welfare encompassing all husbandry and management activities that have a potential to affect the welfare of the fish in our care. This book is an essential purchase for fish veterinarians, fish farmers, fish biologists and those involved in the aquaculture industry and its regulation.
