ABSTRACT

In the years 2002 and 2003 the zooplankton
from the outflows from two retention reservoirs, characterised by different biological
conditions, at the sewage treatment plant in the area of the Chemical Plant Police
was studied. One reservoir was in 70% grown with vegetation, mainly submerged
species and hosted fish, while the other had no fish and its bottom was covered
only in 10% by emerged vegetation. Cyclic appearance of certain zooplankton species
was noted; particularly interesting was increasing abundance of Daphnia magna in
warm seasons. The outflows from the second reservoir contained a greater number
of taxa and greater abundance and biomass of zooplankton, however, the difference was not statistically
significant (p < 0.05).

Key words: artificial reservoirs, Daphnia magna, outflows, water plants, zooplankton.
