Column chromatography (CC), thin layer chromatography (TLC), and high performance liquid chromatography (HPLC) were used to test the impact of Vitaton, which contains a natural form of beta-carotene, on the content of carotenoids in the muscles of Siberian sturgeon, Acipenser baerii Br., and sterlet, Acipenser ruthenus L., reared in recirculating systems. It was confirmed that the overall carotenoid content, including provitamin A, was significantly higher (P lesser 0.05) in the experimental groups of both species that were fed trout granulate supplemented with Vitaton in comparison with the control group fed unsupplemented feed. A total of 21 carotenoids were identified in the material examined, of these echinenone, 3'-hydroxyechinenone, alpha-cryptoxanthin, calthaxanthin, deepoxy neoxanthin, and alpha-doradexanthin occurred only in specimens that had been fed the feed supplemented with Vitaton
