Book excerpt: Prediction equations correlating density of fingerling rainbow trout with growth, yield, and food use efficiency indicated that ammonia nitrogen resulting from high fish densities wes responsible for reductions in all three factors. These predictable density-dependent responses present fish-culturists with alternatives of density selection for evaluation and attainment of specific goals. In examples, fish-culturists, by manipulating density, could achieve rapid growth, produce the maximum weight possible, balance yield with cost, optimize fish quality, or combine two or more of these goals.

Download or read book Physiological Adaptations to Swimming in Fish written by Josep V. Planas and published by Frontiers Media SA. This book was released on 2017-08-16 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Swimming is an integral part of the life history of many fish species as is intimately linked with their ability to express feeding and predator avoidance behaviors, habitat selection and environmental preferences, social and reproductive behaviors as well as migratory behaviors. Therefore, swimming is an important determinant factor of fitness in a true Darwinian sense and, not surprisingly, swimming performance has been often used as a measure of physiological fitness in fish. The main aim of this Research Topic is to showcase some of the current studies designed to improve our understanding of the physiological energetic and metabolic requirements of swimming and of the adaptive responses to swimming in fish.

Download or read book The Biology of Sole written by José A. Munoz-Cueto and published by CRC Press. This book was released on 2019-05-13 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews up-to-date knowledge on the biology of sole (Solea senegalensis and S. solea). These flatfish species are increasingly important in Europe both from the ecological and production point of view. This book is divided into two sections: A. general fisheries, aquaculture and engineering overviews; B. physiological, developmental, rhythmic, welfare and genetic aspects which will be of immense interest for the aquaculture industry. Experts, from both academia and research institutes, provide their expertise on sole biology.

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.
