Compound Feed Technology in Sturgeon Fish Aquiculture
The modern fish processing industry of the Russian Federation sets the task of increasing the efficiency of the use and development of the resource potential of the fishery complex by means of aquaculture and mariculture development, including sturgeon fish breeding. In this case, complex processing through the rational use of by-products of fish and hydrobiont. In Russia, China, the EU and other countries, most fish processing enterprises do not rationally use by-products of fish cutting, which leads to violation of environmental safety (waste deposits are littered with waste from the fishing industry). The article discusses the prospects of using alternative plant materials in the diet of sturgeon fish, presents the recipes for full extruded compound feed for this group of organisms, the quality indicators of compound feed for sturgeon. A comprehensive assessment of the quality of compound feed products was obtained according to the physicochemical and structural indicators of compound feed. The optimal terms and conditions of storage of the obtained feed were found. Based on the performed tests, it was concluded that it is advisable to use raw materials of plant origin in the composition of compound feed, which contributes to the growth of the live weight of fish, leads to the replacement of the costly components of the compound feed with cheaper raw materials of plant origin, provided that the nutritional value is not reduced, and the period and conditions of storage meet the existing requirements.
