Abstract: Four raw and cold-smoked whitefish species of the genus Coregonus, least cisco (C. sardinella), Arctic cisco (C. autumnalis), muksun (C. muksun) and broad whitefish (C. nasus), caught in the Yenisei River (Siberia, Russia) were analyzed. Content (mg per g of product) of long-chain polyunsaturated fatty acids of the omega-3 family (LC-PUFAs), namely, eicosapentaenoic acid (20:5n-3, EPA) and docosahexaenoic acid (22:6n-3, DHA), as well as fatty acid (FA) profiles, were measured. There was no significant decrease in the EPA+DHA content in smoked fish compared to raw fish. Moreover, in least cisco, a significant increase in the EPA+DHA content, from 3.22 ± 0.39 mg ∙ g -1 in raw fish to 5.04 ± 0.50 mg ∙ g-1 in smoked fish, occurred. Thus, smoked fish of the studied species proved to be a valuable source of LC-PUFA for human nutrition. The FA profiles of the examined fish, which reflect their diet, did not change considerably in the process of smoking. Therefore, the FA profiles of smoked fish could be used for verifying label information on species identity and catchment area
