Notes
During the investigations carried out for two years from May to October, it was found that in the eutrophic lake (Mikolajskie) as compared with the mesotrophic lake (Taltowisko): 1. the production of filtrators is greater (about 2 times) and among them that of microfiltrators (rotifers, Bosmina), 2. the ratio of production of predatory Cyclopidae to production of filtrators is smaller, 3. participation of hypolimnion in total lake production is greater, which is caused by great production of Bosmina in this layer.
