Investigations were conducted for fat content and fatty acids composition of six of the most frequently fished species inhabiting the Vistula Lagoon (bream, roach, perch, pikeperch, herring, and eel). Fat content of the fish examined ranged from 0.39 to 29.77 per cent, whereas fatty acids composition range was as follows: saturated fatty acids (SFA) 25.1_29.4 per cent, monounsaturated fatty acids (MUFA) 22.3_52.2 per cent, and polyunsaturated fatty acids(PUFA) 18.5_52.2 per cent. Among the SFAs, palmitic acid dominated (C16:0). Oleic acid (C18:1) had the greatest share of the MUFAs. PUFAs had a high share of acids from the n-3 family, especially of eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids. A high share of these acids was confirmed in the fats of pikeperch (33.25 per cent) and perch (31.02 per cent)
