Lipid production in natural phytoplankton communities in a small freshwater Baltic lake, Lake Schöhsee, Germany

1. Seasonal patterns in lipid production and the photosynthetic parameters describing lipid production in Lake Schöhsee (a small freshwater, mono‐dimictic and moderately eutrophic North German Baltic lake) were determined. 2. The mean lipid fraction of C fixation (LIP‐FCF) was 13.2% (range 7.6–21%), measured bimonthly from January to December 1995. Periods of high nutrient concentration, low temperatures and particular species of algae (diatoms …
