Vitamin content in meat when growing African catfish with probiotics

Abstract

Abstract The article presents the results of the analysis of the content of vitamins in the meat of the African catfish Clarias gariepinus from the Clariidae family, which are widespread in the world’s industrial aquaculture. Studies have shown that African catfish meat contains water- and fat-soluble vitamins. Fat-soluble vitamins are represented by vitamins A and E. The group of water-soluble vitamins consisted of vitamins PP, C, and B vitamins (B1, B2, B5, and B6). Studies have shown that the meat of the studied fish species has a high biological value. It contains functional food ingredients - vitamins A, PP, B1, B5, B6 in an amount of at least 15% of the daily physiological requirement. According to the results obtained, the content of all water-soluble vitamins in the muscle tissue of males exceeds that of females. During the study, it was revealed that the introduction of the probiotic Sporothermine into the fish diet based on the spore forms of the bacteria Bacillus subtilis and Bacillus licheniformis causes a significant increase in the content of some vitamins. In particular, the content of vitamins B5, B6, nicotinic, and ascorbic acid increases. Fat-soluble vitamins showed increased content of vitamin E.
