Аннотация: The review considers probable ways to overcome the deficiency of eicosapentaenoic and docosahexaenoic acids in the human diet through the rational development of aquaculture. Currently, aquaculture is not a producer, but a consumer of polyunsaturated fatty acids, since it is based on feed, the main components of which are fishmeal and fish oil obtained from commercial catches. It is proposed to transform farmed fish from a consumer to producer of these polyunsaturated fatty acids. The source of production of eicosapentaenoic and docosahexaenoic acids in aquaculture can be their synthesis by fish from short-chain alpha-linolenic acid contained in the oil of terrestrial agricultural plants. Calculations of the threshold value of the content of eicosapentaenoic and docosahexaenoic acids in feed for salmon fish (Salmonidae) with partial replacement of fish oil with vegetable oil are presented. Another possible way to transform aquaculture into a producer of polyunsaturated fatty acids is to partially replace fishmeal in feed with flour from terrestrial invertebrates. Some species of insects and worms that are promising for aquaculture as objects for the production of feed meal are considered.

Заглавие : Amino acids in prospective feeds for fish aquaculture: A review of experimental data
Место публикации : J. Sib. Fed. Univ. - Biol.: Siberian Federal University, 2020. - Vol. 13, Is. 4. - С. 424-442. - ISSN 19971389 (ISSN), DOI 10.17516/1997-1389-0332
Аннотация: Total dependence of aquaculture on imports of feeds can significantly compromise Russia's food supply security; hence the task of designing new domestic feeds is of primary importance. A major challenge of world aquaculture is providing fish with a balanced diet, in particular, with a well-balanced composition of amino acids. In this review, we analyze international publications on the composition of amino acids in fish feed over the last two years. We summarize the data on the amino acid composition of prospective food sources for fish aquaculture: agricultural crops, insects, annelids, higher crustaceans, animal waste, phytoplankton, zooplankton, macrophytes, and microorganisms. We performed a comparative analysis of the composition of amino acids in promising aquafeed sources and fish flour traditionally used for fish feeding. Based on the results, we conclude that each of the examined food sources can be used as a component of fish nutrition and offers realistic prospects for production of alternative feeds. To ensure high quality of fish aquaculture products, the priority should be given to development of technologies which allow to control amino acid feed composition during the production process with respect to fish species-specific needs. It is hoped that this review will be useful to researchers and practitioners involved in designing and producing new domestic aquafeed for fish. © Siberian Federal University. All rights reserved.
