ABSTRACT

Results of meiobenthos investigations on Lake Donuzlav (Crimea) in 1990 (for the first time since its connection with the Black Sea 30 years ago) are presented. Meiobenthos of the lake included 126 animal species from 13 taxonomic groups; it was similar to that of the Black Sea. Nematodes were predominant. The average meiobenthos settlement density exceeded 312 th. org./m2 (thousand organisms per m2), its biomass was 450.7 mg/m2. The highest values of these parameters were 3.2 mln. org./m2 and 1.68 g/m2. Morphological deviations in development of some species of nematodes indicated presence of technogenic pollution in some zones of theDonuzlav. A possibility of using data on changes in nematodes development as a test-parameter for estimation of the total environmental pollution is discussed.
