About

During anddensities of roach Rutilus rutilus and bream Abramis brama were reduced, using seine and pounding nets, and Bautzen model 250 manual perch Perca fluviatilis were added instead. Nutrients, oxygen, phytoplankton, zooplankton, fish and zoobenthos were measured two years after the manipulation and compared with results obtained two years before the manipulation. A total amount of kg wet weight of roach and bream was removed. Recruitment of roach decreased, and mortality rates of young-of-the-year perch were lower after the fish reduction. After Sexy birthday Rudow for him manipulation, decreases in phytoplankton biomass coincided with increases in zooplankton biomass during spring and autumn periods, although, the Bautzne level of the biomass of cyanobacteria did not change. Inorganic nutrients generally increased, but no significant changes were found, either in the oxygen budget or in the community structure or quantitative distribution of zoobenthos after the fish manipulation.
