Book Synopsis Feeds for the Aquaculture Sector by : Laura Gasco
Download or read book Feeds for the Aquaculture Sector written by Laura Gasco and published by Springer. This book was released on 2018-03-23 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Brief discusses potential alternative sources for feeds in aquaculture fish diet, and explains that the future of aquaculture’s development is dependent on the costs of fishmeal and fish oil. Considering that the increasing costs of traditional feeds constrain this development, research is looking into alternatives, which can ensure adequate nutrition for animals’ growth. This work reviews the use of alternative plant, microbial and insect protein sources, evaluating in particular their impact on growth, nutrient digestibility, fillet quality traits and sensorial perception in the most important farmed marine and freshwater fish species. The Brief specifically summarizes the pros and cons of plant oils from oilseeds, which can on the one hand be a sustainable substitute for fish oil, but which are on the other hand less rich in omega-3 long-chain polyunsaturated fatty acids. The feeding might therefore result in an undesired reduced nutritional value of the flesh of farmed fish. The authors also explore the possible use of fishery discards as potential aquaculture feed source. Since the landing of by-catch will with the new Common Fisheries Policy (CFP) become obligatory (instead of simply returning it to the sea, often dead), suitable uses of what must not be used for human consumption can be investigated. The authors give an outlook whether this might become a sensible alternative to improve the management of discards and create more sustainable fisheries. The Brief also addresses the issues of additives to aquafeeds, such as vitamins, minerals, and antioxidants, but also immunostimulants and enzymes. The authors discuss which effects these additives may have on fish growth, welfare, reproduction and health status in aquacultures.

Book Synopsis Food Intake in Fish by : Dominic Houlihan
Download or read book Food Intake in Fish written by Dominic Houlihan and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intake of food by fishes is an area of study that is of great importance to the applied sciences of fisheries and aquaculture for a number of reasons. For example a thorough knowledge of factors influencing the ingestion of feed can lead to successful manipulation of the rearing environment of cultured fishes, thereby ensuring improved growth performance and feed utilisation, and decreasing the amount of waste (and consequent pollution) per unit of fish produced. This important book, which has arisen out of a European Union COST programme, illustrates how insights into the biological and environmental factors that underlie the feeding responses of fish may be used to address practical issues of feed management. Food Intake in Fish contains carefully edited contributions from internationally recognised scientists, providing a book that is an invaluable tool and reference to all those involved in aquaculture, especially those working in the aquaculture feed industry and scientific personnel in commercial and research aquaculture facilities. This book should also find a place on the shelves of fish biologists and physiologists and as a reference in libraries of universities, research establishments and aquaculture equipment companies.

Book Synopsis Handbook on Ingredients for Aquaculture Feeds by : J.W. Hertrampf
Download or read book Handbook on Ingredients for Aquaculture Feeds written by J.W. Hertrampf and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 617 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Nutrient Requirements of Fish and Shrimp by : National Research Council
Download or read book Nutrient Requirements of Fish and Shrimp written by National Research Council and published by National Academies Press. This book was released on 2011-05-25 with total page 810 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquaculture now supplies half of the seafood and fisheries products consumed worldwide and is gaining international significance as a source of food and income. Future demands for seafood and fisheries products can only be met by expanded aquaculture production. Such production will likely become more intensive and will depend increasingly on nutritious and efficient aquaculture feeds containing ingredients from sustainable sources. To meet this challenge, Nutrient Requirements of Fish and Shrimp provides a comprehensive summary of current knowledge about nutrient requirements of fish and shrimp and supporting nutritional science. This edition incorporates new material and significant updates to information in the 1993 edition. It also examines the practical aspects of feeding of fish and shrimp. Nutrient Requirements of Fish and Shrimp will be a key resource for everyone involved in aquaculture and for others responsible for the feeding and care of fish and shrimp. It will also aid scientists in developing new and improved approaches to satisfy the demands of the growing aquaculture industry.

Book Synopsis The Influence of Diet and Dieldrin on the Growth and Body Composition of Underyearling Rainbow Trout by : Glenn R. Phillips
Download or read book The Influence of Diet and Dieldrin on the Growth and Body Composition of Underyearling Rainbow Trout written by Glenn R. Phillips and published by . This book was released on 1972 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of a sublethal concentration of dieldrin (0. 2 ppb) in the water on the growth and body composition of underyearling rainbow and cutthroat trout held in aquaria and fed different rations of tubificid worms or Oregon moist pellets were studied at Oak Creek Fisheries Research Laboratory, Oregon State University, during 1970 and 1971. These studies were concerned with: evaluating the nutritional status of some of the foods which had been fed in previous growth experiments conducted with fishes at Oak Creek Laboratories; determining the effects of a sublethal concentration of dieldrin on the growth rates of fish fed each diet; and considering the effects of the nutritional state of fish on their response to a dieldrin stress. An aqueous solution of dieldrin was obtained by passing water at a slow rate through a column made up of uniformly sized rocks previously coated with the pesticide. The water containing dieldrin was then diluted to the desired 0. 2 ppb by means of a series of distribution boxes and siphons before being introduced to 6 of the 12 experimental aquaria. In each experiment the food consumption rates, growth rates and gross food conversion efficiencies were calculated at three feeding levels for both control and dieldrin exposed fish. Growth rates, consumption rates and gross conversion efficiencies for protein were also calculated and accumulation rates were computed for fat. A nutritional comparison of the two diets under controlled conditions showed growth rates and gross food conversion efficiencies for fish fed Oregon moist pellets to be less than those for fish fed tubificid worms. The protein elaboration rates and gross protein conversion efficiencies were also higher in fish fed tubificids. Fat accumulation rates were higher in fish fed Oregon moist pellets at rations below those required for fat maintenance but higher in fish fed tubificids at rations above those required for fat maintenance. Trout fed tubificids and exposed to a dieldrinl stress showed a depression in growth rates and gross food conversion efficiencies at rations near and slightly above maintenance with the pesticide having no effect on pellet fed fish at these feeding levels. Exposure to dieldrin at high rations resulted in lower growth rates in fish fed pellets whereas the growth of fish fed high rations of tubificids appeared to be stimulated by dieldrin. The pesticide appeared to have no effect on gross protein conversion efficiencies and protein elaboration rates for both diets at all rations fed. Dieldrin, instead, influenced the growth of fish fed both diets by affecting their rates of loss or accumulation of fat. Dieldrin increased the rate of fat loss in fish fed tubificids; however, at rations above fat maintenance the pesticide increased fat accumulation rates in fish fed tubificid worms while decreasing fat accumulation rates in fish fed Oregon moist pellets. Differences in the nutritional states of the fish fed the two diets caused noticeable differences in their responses to a dieldrin stress, indicating diet as a possible factor in experimental outcome.
