Influence of the Kaniv Hydroelectric Power Station Operation on Trichoptera Larvae (Insecta) of Periphyton Communities on the Embankments of the Tail Waters

摘要

Data on the species composition, numbers, and biomass of Trichoptera larvae in periphyton communities of the embankments of the tail waters of the Kaniv Hydroelectric Power Station are given in the paper. Regularities of changes in their numbers and biomass depending on the distance from the dam of the Kaniv Hydroelectric Power Station were studied in different seasons. Relationship was established between the growth rate of Trichoptera larvae and the distance from the dam.
