The species diversity and quantitative characteristics of zooplankton of the lake Chany in 2001-2002 were studied. 76 species - 35 rotifers, 31 claocera and 10 copepoda species - were detected. Comparison of zooplankton communities in lake sites of different mineralization degree shows that as the salinity in the lake Chany increases, the fresh water zooplankton complex becomes replaced by saliferous water complex. The number of species diminishes from 71 in fresh water to 28 in salted one. The biological diversity of zooplankton brusquely drops as mineralization increases from 1 to 3
