Abstract

The Oligochaeta and the Chironomid fauna were investigated in the Ki>rijs/Cri§ river system from the spring area to the inflow in the years of 1994-1995, to cover up the species living there. A zero-state was made. Specimen density of Oligochaetae was high on the polluted river parts, Limnodrilus hoffmeisteri and Tubifex tubifex were dominant there. Specimen density increased by moderated, and decreased by hard pollution effects. More than 50% of the Chironomid species were found in one sample only, which shows mosaic-like fauna. The presented species could not be rare, or threatened, because of the lack of the earlier faunistical investigations. Br ilia longifusca, Brilia modesta, Rheocricotopus effusus, Briophaenocladius nitidicollis, Chironomus fluviatilis, Paralauterborniella nigrohalteralis and Thienemanniella lentiginosa were typical for clean water river parts. The changes in the fauna picture would show the positive, or negative effects in the river system during future investigations.
