Algae with the size exceeding 50 μm accounted for 61, 34, and 19% of the total phytoplankton production. The release of extracellular products (dissolved organic matter) by the phytoplankton was estimated at 15, 9, and 0.8% of total carbon photosynthetically assimilated in mesotrophic, eutrophic, and hyper-trophic water bodies, respectively. %8 1998-02-01
