РЕЗУЛЬТАТЫ ВЫРАЩИВАНИЯ АВСТРАЛИЙСКОГО КРАСНОКЛЕШНЕВОГО РАКА (CHERAX QUADRICARINATUS) В ИНДУСТРИАЛЬНЫХ УСЛОВИЯХ

Abstract

The article presents the results of artificial cultivation of planting material and commercial products of the Australian red-clawed crayfish (Cherax Quadricarinatus) in industrial condition. Experimental cultivation of crayfish was carried out in specialized multi-tiered closed water supply systems for crustaceans, using tap water. The values of hydrochemical parameters of which were within the optimal limits for crayfish. Data on the dynamics of absolute, relative, average daily gain and survival of crayfish are presented. The parameters of the growth rate are determined by the values of the coefficients of mass accumulation and growth rate. Data on feeding the Australian red-claw crayfish with various feeds are presented, indicating the feed coefficients. Research has shown that the cultivation of Australian red-claw crayfish in industrial conditions is possible, and the production of planting material and commercial products at fish farms is relevant and economically attractive for aquaculture in Kazakhstan. The development of biotechnical methods and standards for the cultivation of Australian crayfish, as well as the development and production of high-quality domestic specialized compound feed for these objects will in the future provide an opportunity to actively develop this area of aquaculture in the country. The developed biotechnical methods can be used in the cultivation of Australian red-claw crayfish in fish farms in the Republic of Kazakhstan.
