The role of storage lipids in vertical migrations of the beaked redfish (Sebastes mentella) in the North Atlantic
Year: 2024
Type: article
Abstract: The content of the main classes of storage lipids – triacylglycerols, cholesterol esters and waxes – in the muscles and liver of the beaked redfish (Sebastes mentella) and their changes in the depth gradient and in different areas of the North Atlantic were studied. Significant differences in the quantitative content of reserve lipids in beaked redfish’s from different fishing horizons were established. The analyzed changes the lipids in tissues and organs of fishes with increasing depth indicate the use of triacylglycerols, cholesterol esters and waxes as energy sources, as well as for maintaining buoyancy of the organism during vertical migration. The results of the study can be used for further study of the migration biochemical mechanisms of the commercial sea bass species of the North Atlantic – the beaked redfish, as well as other aquatic organisms with similar swimming activity. Reliable differences in the quantitative content of reserve lipids in sea bass from different fishing horizons were established.
