Some of fish species as a source of n-3 polyunsaturated fatty acids

Abstract

Muscle lipids of ten fish species (freshwater: zander, whitefish, roach, burbot and crucian carp; farmed: rainbow trout and carp; and Baltic species: garfish, flounder and sprat) were analysed for fatty acids composition (GC/MS), lipid fractions (HPLC) and susceptibility to oxidation. 100 g of meat of lean freshwater and Baltic fish (roach, flounder, burbot and zander) can provide 50% less n-3 PUFAs than the meat of rainbow trout or whitefish and 4-6 times less than sprat. The susceptibility to oxidation of freshwater fish lipids was higher than in the Baltic species of similar PUFAs content.
