Sažetak
In the waters of the Reserve in 1984—85 in total 267 phytoplankton taxa were established, with Chrysophyta (Bacillariophyceae) and Chlorophyta predominating. In the period of investigation the bigest Kopacko Lake was floristical the reachest, but the deepest Sakadasko Lake was the poorest because of negative influence by waste waters.
Calculated coeficient of floristical similarity showed that floristical were the most simillary localities which was the nearest localities, but opposite of this the farthest localities had the least floristical similarity.
The greatest value of plankton primary production was the most frequently established in the surface layer on all localities (except Sakadasko Lake) and it was decreasing towards the depth of 1 metre.
According to the saprobiological analysis of phytoplankton it is obvious that quality of water, in investigated localities, belongs to beta- mesosaprobic degree, except the water of polluted Sakadasko Lake which belongs to beta-alpha or alpha-mesosaprobic degree.
