Fatty acid composition of fish of the Selenga River delta

Fish as a source of essential nutrients occupies a significant place in healthy human nutrition. To assess the nutritional value of the six main commercial fish species (common roach Rutilus rutilus, common bream Abramis brama, crucian carp Carassius carassius, common carp Cyprinus carpio haematopterus, European perch Perca fluviatilis, and northern pike Esox lucius) from the Selenga River delta we determined the fatty acid composition and lipid quality indices of the muscle tissues. It was identified total of 19 to 32 fatty acids depending on the species. The total content of polyunsaturated fatty acids is higher in E. lucius and R. rutilus, saturated fatty acids - in C. carassius, P. fluviatilis and A. brama, and monounsaturated fatty acids - in C. carpio haematopterus. The calculated lipid quality indices indicate the high nutritional value of muscle tissue of the studied fish.
