Zooplankton of lake Dolgoye (Belarus) and its vertical distribution.
Abstract
The paper presents results of studies species composition, abundance and vertical distribution of pelagic zooplankton in the Dolgoye Lake. Maximum animal densities pointed out in the surface well-heated and aerated layers of epilimnion. Metalimnion and hypolimnion zones characterized by lower values of total abundance. There are different in maximum of crustaceans and rotifers abundance. Most populations have species-specific features of vertical distribution and prefer the certain layers of water.
