FORMATION OF ZOOPLANCTONE IN FISH BREEDING PONDS WITH CONTINGENT WATER SUPPLY OF CASCADE TYPE

Abstract

Research was carried out on the subject of species richness and the taxonomic structure during the entire growing season. Densities levels, biomass and dynamics of zooplankton development in three feeding carp ponds with dependent water supply of the fish factory «Beloye» in the Zhitkovichsky district of the Gomel region were assessed. Ponds are similar in terms of areas, densities of growing a year old carp and the volume of introduced mixed fodder. As a result of the research, was established that as a result of the transfer of organic matter in the ponds of the cascade in the Lower Pond, the level of development of zooplankton is three times higher than in the Upper Pond. The fish production of the Lower Pond was also 25%
