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.

Download or read book Improving and Characterizing the Nutritive Value of Feather Meal Using Rainbow Trout Oncorhynchus Mykiss as a Biological Model written by Guillaume Pfeuti and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Feather meal (FeM) is a high-protein and cost-effective feed ingredient, made from the steam-hydrolysis of keratin waste products generated by the animal processing industry. Keratins are composed of ~90% indigestible protein highly cross-linked with disulphide bridges. Steam-hydrolysis promotes the disruption of disulphide, peptide, and hydrogen bonds, allowing peptides to become digestible and amino acids absorbable. The variability of the nutritional value of FeM is the result of the use of different raw materials and processing conditions during the production of this ingredient. Variations of heat processing conditions create disparities of disulphide conformers, D-amino acids, and cross-linked amino acids contents, and these affect the nutritional value of protein ingredients. Better understanding of the chemical interactions occurring during the processing of FeM would enable the development of methods to improve and estimate the nutritional value of this ingredient, which could assure the quality of FeM to feed stakeholders. FeMs were hydrolyzed using a novel enzymatic pre-treatment with the aim of better understanding the effects of peptide and disulphide bonds on the digestibility of amino acids and bioavailability of test amino acids (arginine) in this ingredient by rainbow trout. In a first study, a bench-scale trial was carried out to determine the potential of incubating FeM with sodium sulfite and proteases to cleave disulphide and peptide bonds, respectively. Subsequently, a pre-treatment to improve the nutritional value of FeMs was developed. In a second study, the bioavailability of arginine in two FeMs and in their pre-treated counterpart (PTFeM) were assessed through a growth trial using rainbow trout. In follow up studies, the apparent digestibility of amino acids in the same FeMs and PTFeMs were assessed in rainbow trout. The disulphide and cross-linked amino acid contents in the four ingredients were quantified in an attempt to determine the factors affecting their digestibility and bioavailability. Results from this thesis demonstrate that a simple treatment targeting the disruption of disulphide and peptide bonds effectively improves the bioavailability of arginine and the digestibility of amino acids in FeMs. Furthermore, this thesis gives insight on the effect of structural and chemical characteristics of protein on the nutritional value of FeM.

Download or read book Aquaculture Nutrition written by Daniel L. Merrifield and published by John Wiley & Sons. This book was released on 2014-10-20 with total page 519 pages. Available in PDF, EPUB and Kindle. Book excerpt: Manipulation of the microbial gut content of farmed fishes and crustaceans can have a marked effect on their general health, growth, and quality. Expertly covering the science behind the use of prebiotics and probiotics this landmark book explains how the correct manipulation of the gut flora of farmed fishes and crustaceans can have a positive effect on their health, growth rates, feed utilization, and general wellbeing. Aquaculture Nutrition: Gut Health, Probiotics and Prebiotics provides a comprehensive overview of the current knowledge of the gut microbiomes of fish and their importance with respect to host-fish health and performance, providing in-depth, cutting-edge fundamental and applied information. Written by many of the world’s leading authorities and edited by Dr Daniel Merrifield and Professor Einar Ringø, this important book discusses in detail the common mechanisms for modulating microbiomes, particularly at the gut level (e.g. probiotics, prebiotics and synbiotics). The book is a key resource for an understanding of the historical development of these products, their known mechanisms of action and their degree of efficacy as presently demonstrated in the literature. The fundamental material provided on the gut microbiota itself, and more broad aspects of microbe-live feed interactions, provide essential reading for researchers, academics and students in the areas of aquaculture nutrition, fish veterinary science, microbiology, aquaculture, fish biology and fisheries. Those involved in the development and formulation of aquaculture feeds and those with broader roles within the aquaculture industry will find a huge wealth of commercially-important information within the book’s covers. All libraries in universities and research establishments where biological sciences, nutrition and aquaculture are studied and taught, should have copies of this excellent book on their shelves.

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.
