Structure and distribution of zooplankton in the central district of Votkinsk reservoir

The article discusses the results of stationary investigations of the zooplankton community in the Central district of Votkinsk reservoir, conducted during the growing seasons of 2004, 2005, 2012. The features of the taxonomic composition, spatial distribution, seasonal and long-term dynamics of zooplankton in General and its major groups: rotifers, cladocera and copepods. Crustaceans constitute the bulk of the taxonomic composition of the zooplankton of the Votkinsk reservoir. Cladocera dominated by quantitative indicators of development in all areas of the reservoir and form a limnological plankton. During the growing season, the abundance and biomass of the zooplankton community reaches maximum development in macrophyte thickets shallow left Bank, in other zones of the reservoir animal plankton is very poor. The level of development of zooplankton communities of the central area of the Votkinsk reservoir can be attributed to the reservoirs а-oligotrophic class.
