The prospects for the development of aquaculture in Kazakhstan through the application of industrial technologies are indisputable, with an imperative to expand the range of cultivated species. Of particular interest within the Republic of Kazakhstans aquaculture context is the Australian red claw crayfish (Cherax quadricarinatus). This study marks the pioneering effort to cultivate C. quadricarinatus under industrial conditions within Kazakhstani fish farms. This article presents the results of industrial cultivation endeavors for C. quadricarinatus planting material. Various biotechnical methods were employed, including recirculating water supply installations, aquaria, pools, and trays. These methods were tested using both natural water sources and water from artesian wells. The cultivation systems encompassed both direct-flow water supply and forced water circulation facilitated by pumps. The study shows the dynamic trends in absolute and average daily growth, as well as survival rates of C. quadricarinatus juveniles and fingerlings within these proposed conditions. Growth rate evaluation was based on criteria such as mass accumulation coefficients, specific growth rates, and survival rates. Additionally, the study explores the feasibility of employing diverse types of feed-both of animal and plant origin, based on coefficients related to artificial feed. Finally, the study puts forth theoretical and practical foundations for applying biotechnical standards to the cultivation of C. quadricarinatus planting material, specifically tailored for entrepreneurs within the Republic of Kazakhstan.
