Comparison of technological characteristics of Clarias gariepinus hybrid progress with the parental individuals

African catfish is popular among domestic fish farmers due to the high yield of high-quality commercial products and inedible parts of the fish suitable for processing. The paper presents a comparative characteristic of the mass composition of parts during cutting and morphometric data of the hybrid offspring of the African clariid catfish Clarias gariepinus with parental lines - Mikhailovskaya and Tamanskaya breeds, grown to marketable weight in RAS conditions. A histological comparison of muscle tissues of fish in the experimental groups was also carried out. The results of the histological analysis of the tissues revealed a significant difference in the area of muscle fibers in females (by 27.1%) compared to males Clarias gariepinus. It is shown that the hybrid offspring have an increased growth rate (achieving a marketable weight of 1200 g in 10 months of cultivation) compared to the parental lines (weight 1100 g in 15 months of cultivation). It was found that hybrid females are significantly fatter compared to Mikhailovsky and Taman individuals. When comparing the technological indicators of fish, no significant differences were found between the groups at the processing stage. For further intensification of warm-water aquaculture in Russia, interbreeding hybridization of African catfish is a promising solution. The studies have shown that hybrid offspring significantly exceed parental lines in growth rate, while not inferior in weight, length, or in the yield of edible parts of the fish (carcass, fillet, etc.). Therefore, interbreeding hybridization, which shows successful results, is a promising direction in aquaculture and processing of African catfish.
