CILIATE (CILIOPHORA) OF FISH PONDS OF KYIV REGION. II. DEMERSAL PLANKTON

In 1988 and the first half of 1989 the free-living plankto-benthic ciliates (Ciliophora) of fish waters (the Dnieper basin, Kyiv Province) were investigated. Two fish ponds and one reservoir of complex assignment were investigated. In these waters 106 species and varieties of ciliates were found, two of them were new for Ukraine. Seasonal dynamic of quantity and biomass, as well as production and destruction of organic substances by ciliates were studied. The average data of quantity and biomass of ciliates, and their functional activity in fish ponds do not differ statistically reliable from the reservoir of complex assignment, but their seasonal changes differ significantly (substantially higher in the summer time).
