Methods

The samples of zooplankton and zoobenthos have been collected in the following periods: July 31 - August 3 1998 3-5 August 1999 July 29 - August 3 2009 26-28 July 2010 and July 29 - August 7 2012 as well as historical data relating to the end of July beginning of August 1965 1968 and 1969 and published data (Baranowska 1976 1978; Kutikova 1978; Popov 1976).. Zooplankton samples were taken with quantitative Juday net plankton sampler Rutnera or 10-liter bucket straining volumes of water (50 liters) through Apshteyna net. All nets used kapron sieve with a mesh size of 80 microns. Samples were fixed with 4% formalin. Laboratory processing of plankton samples were performed by standard methods (Guidelines ... 1984). Names of taxa are given in accordance with the work (determinant zooplankton ... 2010). For comparison of quantitative indicators of zooplankton used archival materials only of 1968 1969 years because in 1965 for the selection of zooplankton samples used kapron sieve with a larger mesh size (Baranowska 1976).
