Abstract

Correlation of the present work on the fatty acid composition of algae (Chlorella vulgare, Diatomea vulgare), planktonic crustaceans (Daphnia cucullata, Diaphanosoma brachiurum, Eudiaptomus gracilis, Mesocyclops leulcarti) and plankton feeding fishes (Alburnus alburnus, Pelecus cultratus) and of the carp (Cyprinus carpio) with results obtained by other workers, suggests that the metabolism concerned in the formation of the characteristic fatty acid composition of aquatic animals may be as follows: 1. Biosynthesis of linoleic and linolenic acid in members of the phytoplankton. 2. Formation of eicosa and docosapolyenoic acids in some planktonic crustaceans. The bulk of these fatty acids accumulate inthe phospholipids. 3. Redistribution of long chain polyunsaturated fatty acids in tlxe triglicerides and phospholipids of fishes. 4. De novo synthesis of saturated fatty acids from non lipid precursors and their desaturation to monoenoic fatty acids may take place in each member of the food chain.
