1. In the Finnish coastal waters phytoplanktonic diatoms dominate in early summer, changing to zooplanktonic Rotatoria in June and later to Copepoda.

2. The lipid contents in plankton varied from 0.2 to 2.5% wet weight or from 1.9 to 17.0% dry weight, respectively.

3. Triglycerides and polar lipids together dominated in phytoplankton while polar lipids alone were the major lipid in zooplankton. Exceptionally high proportions of free fatty acids existed in most samples whereas wax esters were detected only as minor components.

4. Over two thirds of the fatty acids in phytoplankton were composed of C16 acids, whereas palmitic acid together with polyenoic C20 and C22 acids dominated in zooplankton.

5. Monoenoic C20 and C22 acids, often abundant in copepods, were found only in minor amounts in this study.
