Abstract
For the first time the fatty acid composition of deep-water Baikal amphipoda Ommatogammarus albinus sampled with the help of deep-water manned submersible units «Mir» was studied. Using the technique of chromatography–mass spectrometry, in the tissue of Baikalian amphipoda there have been 40 fatty acids observed those exhibit different unsaturation level with a high content of monounsaturated fatty acids, such as oleic acid, 18:1n9. A high ratio 18:1n9/18:1n7 and relatively low ratio values 16:1n7/16:0 and 20:5n3/22:6n3 indicate that deep-water amphipoda Ommatogammarus albinus belong to necrophages.
