The rise into global prominence and rapid growth of finfish and crustacean aquaculture has been due, in part, to the availability and on-farm provision of feed inputs within the major producing countries. More than 46 percent of the total global aquaculture production in 2008 was dependent upon the supply of external feed inputs. For the aquaculture sector to maintain its current average growth rate of 8 to 10 percent per year to 2025, the supply of nutrient and feed inputs will have to grow at a similar rate. This had been readily attainable when the industry was young. It may not be the case anymore as the sector has grown into a major consumer of and competitor for feed resources. This paper reviews the dietary feeding practices employed for the production of the major cultured fed species, the total global production and market availability of the major feed ingredient sources used and the major constraints to feed ingredient usage, and recommends approaches to feed ingredient selection and usage for the major species of cultivated fish and crustacean. Emphasis is placed on the need for major producing countries to maximize the use of locally available feed-grade ingredient sources, and, in particular, to select and use those nutritionally sound and safe feed ingredient sources whose production and growth can keep pace with the 8 to 10 percent annual average annual growth of the fed finfish and crustacean aquaculture sector.

This book provides a historical and analytical account of changes in the seafood supply chain in Britain from the mid-twentieth century to the present, looking at the impact of various types of governance. The governance of marine fisheries has been a contested issue for decades with increasing anxieties about overfishing. In tandem, the rise of aquaculture, fish and shellfish farming, has driven another set of environmental concerns. In the food system, there have been scandals about safety failures and about fraud. At the same time, governments issue advice urging people to eat fish for its health benefits. In the context of these problems and contradictions, how have governments, the food industry and ordinary consumers responded? The author shows how different types of governance and regulation have been used to seek seafood sustainability and food safety and to communicate nutritional messages to the public and with what effects. The book also presents a new model for understanding food chains which combines governance and power approaches with an emphasis on understanding the interests served and the resulting balance of public and private benefits. This shows that the role of state regulation should have greater emphasis in governance and agri-food analysis and that theories about supply chain functioning, including the part played by major retailers and civil society, should be modified by a more nuanced understanding of the role of standards and certification systems. Although much of the focus is on the UK and Europe, this book provides key lessons internationally for the governance of seafood and other agri-food supply chains. The book will be of interest to students of food policy and those working in the seafood industry or studying for connected qualifications, and more widely to readers with an interest in seafood issues and problems.

The Siberian sturgeon, Acipenser baerii Brandt 1869 is the most widely farmed sturgeon species. Continuing from Volume 1, which focuses on the biology of the species, the present Volume 2 in turn examines farming aspects. It is divided into six parts, the first of which deals with reproduction and early ontogenesis, i.e. reproductive cycles, controlled reproduction, sperm cryoconservation, and weaning of larvae. The second covers the growing phase with a focus on food and feeding (management, fish meal replacement, potential endocrine disruptions, usefulness of prebiotics and immunostimulants, and nitrogen excretion). Production-related data are the focus of the third part and include: characteristics (countries, structures of production, evolution in production, economic features) of the gross production of the species (meat and caviar) worldwide, a method for assessing the quality of caviars, off-flavors management, and an example of production of fingerlings for restocking. Part four addresses selected long-term management issues: genetic variability of brood stocks, genome manipulation and sex control, and the advantages of hybrids. The next three chapters constitute the fifth part, which is devoted to health status (immunology and welfare). In closing, the absence of ecological risks of introducing the species in non-native waters is shown using two long-term documented examples (Russia and France). Three methodological chapters round out the volume, covering: in vitro incubation of ovarian follicles, a richly illustrated library of echographies and photos, and a detailed presentation of oxygen demand studies.

This book is about important relevant recent research topics in sustainable aquaculture practices. A critical assessment of the sustainable fishing methods and the aspect of sustainable aquaculture feed is presented in this volume. A special focus has been given to socio-economic and environmental assessment of aquaculture practices and analysis of carbon footprint under an intensive aquaculture regime. Aquaponics as a niche for sustainable modern aquaculture has been highlighted. The effect of use of pharmaceuticals to prevent fish disease on the surrounding marine environment is an emerging area of concern, and a critical discussion on this aspect is included in the book. The spread of organic waste and nutrients released by fish farms to natural water bodies has raised considerable concerns. Therefore the methods to prevent their dispersion and removal (treatment) have been comprehensively covered in this book. This book is an essential read for academician, researchers, and policy makers in the field of aquaculture.

The edited book covers the climate change impact broadly across the ecosystems including increasing pressure on livelihood and food supplies to the society. Climate change, in particular, rising temperatures, can have both direct and indirect effects on global fish production. Fisheries and aquaculture is one of the important sectors of agriculture for livelihood and nutritional security. Fish, being poikilothermic in nature are very sensitive to any change in the ecosystem. In commercial aquaculture, it is crucial to ensure that environmental rearing conditions are adequate, if not optimal, for fish growth, welfare and profitability. Thus, the book develops an understanding regarding changes in relevant environmental parameters and its affect in the growth and physiological performance of fish. Fish feeds on natural food organisms, but the adverse changes in the ecosystem attracts nutritionists to provide better food and feeding strategies for optimum growth and survival of the fish. it is become necessary to develop preparedness about the changes and their mitigation strategies through fish nutrition and feeding strategies. This book addresses the potential impact of climate change on the aquaculture sector under sections - Assessment of Global Warming Impact on aquatic resources and fish production, Adaptation in Fish Digestive Physiology and Biochemistry under Changing Environment, Prioritization of fish feed technology with respect to changing climate for adaptation and mitigation, Strategies and planning on reproductive physiology and feed management for biodiversity conservation. The chapters are contributed by the experts in the field of fish nutrition and physiology. The book assists fish farmers, entrepreneurs, planners and advisors specifically related to nutritional and physico-biochemical changes in fishes to adapt or mitigate the adverse effect of climate change.
