As part of the Scientific and Technological Program (STP) for the project «Approbation and Implementation of Effective Biotechnical Methods for Cultivating Promising Aquaculture Objects in Kazakhstan Fish Farms with Genetic Identification Using DNA Markers,» the «Fisheries Scientific and Production Center» LLP is conducting research on new aquaculture species for the Republic of Kazakhstan: Tench and Giant River Prawn (Macrobrachium rosenbergii). The overwintering of these objects was successfully completed in a Recirculating Aquaculture System (RAS) at the fish farming site of the Balkhash branch of the «Fisheries S&PC» LLP.<\/p>\n

From April 14 to 16, a team consisting of Senior Researcher of the Aquaculture Laboratory N.S. Badryzlova, Head of the Complex Laboratory F. Altayeva, and Laboratory Assistant J.S. Seitpatkalov conducted a harvest of the RAS, performed grading (bonitiravka), and took measurements of the research objects. During the process, the prawns were sorted and transferred into square tanks with a volume of 0.2 m\u00b2, while the tench were placed in five circular tanks with a volume of 3 m\u00b3. The RAS is supplied with water from the municipal water system. Key hydrochemical parameters, such as water temperature and dissolved oxygen content, are monitored daily in the tanks.<\/p>\n

In accordance with the project’s target indicators, an article was published on April 16 of this year in the Scopus database, in the high-ranking Swiss journal Fishes (Q2, 59th percentile), titled: «Phenotypic Variability and Adaptive Differentiation of Tench (Tinca tinca L.) from Aquaculture and Natural Populations in Southern Kazakhstan.»<\/i> Foreign experts highly praised the fundamental scientific novelty of the research, specifically highlighting the pronounced plasticity of the tench and its high adaptive capacity to aquaculture conditions.<\/p>\n

The results of the morphological analysis demonstrate the significant potential of this species for efficient cultivation in controlled environments. It has been established that tench can successfully adapt to various technological regimes, making it a promising object for expanding aquaculture production.<\/p>\n
