Fatty Acid Composition and Contents of Seven Commercial Fish Species of Genus Coregonus
 from Russian Subarctic Water Bodies

The study reveals the results of the analysis of fatty acid composition of muscle, liver and gonad tissues of the whitefish Coregonus lavaretus L. of different ages from lakes Lovozero and Umbozero of the Kola Peninsula. The analysis of fatty acid composition in organs and tissues allows to evaluate the physiological characteristics of the organism. It was found that the content of monoenoic fatty acids in the muscles of the whitefish from lake Lovozero is higher than that of the whitefish from Umbozero. It is probably due to the features of the food base of the objects studied. In the muscles of immature whitefish of lake Umbozero the content of polyenic fatty acids is higher compared to the fish from Lovozero. The content of PUFA significantly increases in the mature whitefish from Umbozero lake perhaps due to the temperature regime in water bodies and different rates of motor activity of fish. Lower levels of PUFA in the liver of the whitefish from Lovozero lake may indicate reduced metabolism in hepatocytes. In the gonads of female whitefish from the studied water bodies, the content of saturated fatty acids is low compared to the polyene fatty acids which is characteristic for the viscosity reduction in the membranes of oocytes.

The fatty acid comparative essay of high aquatic plants: Typha latifolia L., Ceratophyllum demersum L. and Veronica anagallis-aquatica L. from water bodies of Baikalian region was carried out. For the first time this biochemical parameter of water form V. anagallis-aquatica was compared with that of coastal-water T. latifolia and submerged C. demersum. The fifteen individual molecules of fatty acids with a chain length from 12 to 22 carbon atoms have been identified by the method of gas liquid chromatography – mass spectrometry. The fatty acid composition of investigated species was different. Among the fatty acids saturated and unsaturated molecules was found, the most distributed fatty acids was saturated palmitic (С16:0), steric (С18:0) and unsaturated linoleic (С18:2 w6), α-linolenic (С18:3 w3). In total, the C16 and C18 acids in studied species accounted for 98%. Differences in the composition of fatty acids of the studied species are discussed from the standpoint of the characteristics of fatty acid metabolism depending on the habitat of plants and are considered as one of the mechanisms of their adaptation to late vegetation. Studies of the fatty acid composition of aquatic organisms contribute to the overall strategy of plant adaptation to changing environmental conditions and are important for the ecological and biochemical monitoring of the ecological status of water bodies.

Background: Fishes are good sources of the fatty acids such as ω-3 and ω-6 polyunsaturated fatty acids, and fat-soluble vitamins for human consumption which play vital roles for various biological processes in the body and help in the proper growth and prevention of diseases. Objective: The objective of the present study was to determine the fatty acid composition, cholesterols, triglyceride and vitamin contents of some selected fishes from Hel river, Assam, India. Methods: Fatty acid composition of fish species was examined using gas chromatography-mass spectrometry, lipid components were determined following the reported methods and vitamins A and D contents were investigated by reversed-phase high-performance liquid chromatography. Results: Fatty acid compositions varied from 51.20-89.47% of saturated fatty acids, 0.27-19.68% of monounsaturated fatty acids and 1.75-30.76% of polyunsaturated fatty acids. Eicosapentaenoic acid and docosahexaenoic acid ranged from 0.54-22.30% and 1.26-18.85%, respectively. The fish species showed varying amounts of lipid components. The vitamins A and D were found in the range of 15.85-1287.0 μg/100 g and 45.0-677.24 μg/100 g, respectively. Conclusion: The fish species of this study are found rich in ω-3 polyunsaturated fatty acids such as eicosapentaenoic acid and docosahexaenoic acid along with noticeable amounts of vitamins A and D. Hence, these fish species have the potentials to serve as the natural dietary supplements for ω-3 fatty acids and other nutrients.
