Fatty acid composition of the tissues of Coregonus lavaretus L. of the Kola Peninsula

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...

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.
