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.
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.

Download or read book Edible Insects written by Arnold van Huis and published by Bright Sparks. This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Edible insects have always been a part of human diets, but in some societies there remains a degree of disdain and disgust for their consumption. Although the majority of consumed insects are gathered in forest habitats, mass-rearing systems are being developed in many countries. Insects offer a significant opportunity to merge traditional knowledge and modern science to improve human food security worldwide. This publication describes the contribution of insects to food security and examines future prospects for raising insects at a commercial scale to improve food and feed production, diversify diets, and support livelihoods in both developing and developed countries. It shows the many traditional and potential new uses of insects for direct human consumption and the opportunities for and constraints to farming them for food and feed. It examines the body of research on issues such as insect nutrition and food safety, the use of insects as animal feed, and the processing and preservation of insects and their products. It highlights the need to develop a regulatory framework to govern the use of insects for food security. And it presents case studies and examples from around the world. Edible insects are a promising alternative to the conventional production of meat, either for direct human consumption or for indirect use as feedstock. To fully realise this potential, much work needs to be done by a wide range of stakeholders. This publication will boost awareness of the many valuable roles that insects play in sustaining nature and human life, and it will stimulate debate on the expansion of the use of insects as food and feed.
Download or read book Small scale Aquaponic Food Production written by Christopher Somerville and published by Fao. This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This technical paper begins by introducing the concept of aquaponics, including a brief history of its development and its place within the larger category of soil-less culture and modern agriculture. It discusses the main theoretical concepts of aquaponics, including the nitrogen cycle and the nitrification process, the role of bacteria, and the concept of balancing an aquaponic unit. It then moves on to cover important considerations of water quality parameters, water testing, and water sourcing for aquaponics, as well as methods and theories of unit design, including the three main methods of aquaponic systems: media beds, nutrient film technique, and deep water culture. The publication discusses in detail the three groups of living organisms (bacteria, plants and fish) that make up the aquaponic ecosystem. It also presents management strategies and troubleshooting practices, as well as related topics, specifically highlighting local and sustainable sources of aquaponic inputs. The publication also includes nine appendixes that present other key topics: ideal conditions for common plants grown in aquaponics; chemical and biological controls of common pests and diseases including a compatible planting guide; common fish diseases and related symptoms, causes and remedies; tools to calculate the ammonia produced and biofiltration media required for a certain fish stocking density and amount of fish feed added; production of homemade fish feed; guidelines and considerations for establishing aquaponic units; a cost-benefit analysis of a small-scale, media bed aquaponic unit; a comprehensive guide to building small-scale versions of each of the three aquaponic methods; and a brief summary of this publication designed as a supplemental handout for outreach, extension and education.

Download or read book Guidelines for feed use in carp and trout production systems in Central Asia and Eastern Europe written by Shipton, T. A. and published by Food & Agriculture Org.. This book was released on 2021-07-06 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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).
