Abstract:	Using column (CC), thin-layer (TLC), and high-performance liquid chromatography (HPLC), carotenoid content was examined in various body parts (fins, skin, muscles, liver, intestines, and gonads) of Atlantic salmon (Salmo salar L.) and Arctic charr (Salvelinus alpinus L.) specimens from an ocean ranching farm. Sixteen carotenoids were identified in the specimens examined - 11 in Atlantic salmon individuals and 15 in Arctic charr. In both the Atlantic salmon and Arctic charr individuals, ketocarotenoids were the predominant group, of which ß - doradexanthin, canthaxanthin, and astaxanthin were the most numerous in Atlantic salmon and phoenicoxanthin, canthaxanthin, and astaxanthin in Arctic charr. Total carotenoid content in all the body parts examined, apart from the gonads, was higher in the males of both species compared to the females. A comparison of the total carotenoid content in the muscles (with the skin) of both fish species with data obtained by other authors for these and other salmonid species indicates that, conversely to other breeding methods, breeding Atlantic salmon and Arctic charr in an ocean ranching farm does not significantly reduce carotenoid content in the muscles.
