Content of Non-polar Lipids in Liver of Fishes of Small Rivers of the Western Podillya (Ukraine)

Results are presented of study of lipid composition in liver of the most common freshwater fishes of small rivers of the Western Podillya − carp, crucian carp, perch and pike. Interspecies differences in lipid content and ratio of lipid classes in liver cells of fish taken from various small rivers were studied. The changes of fractional composition of lipids as a response to the effect of environmental factors, useful for biomonitoring of the aquatic ecosystems, were considered.
