Abstract
The lipid and fatty acid content of benthopelagic scavenging amphipods Ommatogammarus flavus and O. albinus from different depths of Lake Baikal were studied. These amphipods, known to move across a wide range of depths in Lake Baikal, had a relatively high level of total lipids (up to 46% dry weight) in comparison to other aquatic amphipods. This high level of total lipids resulted from a high concentration of storage lipids (triacylglycerols). The monounsaturated 18:1(n-9) acid in combination with 16:1(n-7), and 18:1(n-7) fatty acids were dominant in the amphipods, reflecting their deep-dwelling scavenging mode of life. Local groups of amphipods were distinguished along a Lake Baikal depth gradient based on the primarily diet-associated differences in fatty acid composition.
