Abstract
We studied fatty acid (FA) contents and composition of cladocerans and copepods from warm and cold lakes. We found no significant differences in FA percent levels and FA per carbon contents among cladocerans from the warm lake and the cold lakes, as well as among copepods. Discriminant analysis showed that all cladocerans differed from copepods mainly by the content of docosahexaenoic acid (DHA). Besides, the copepods compared to the cladocerans had significantly higher levels of C22 polyunsaturated FA. Thus, we concluded that cladocerans and copepods in all environments had comparatively invariant taxon-specific composition and content of long-chain highly unsaturated fatty acids (HUFA). According to HUFA content all studied copepods can be regarded as a valuable food for fish.
