摘要：
In addition to several periodic tributaries, the mountain lake Izra (488 above sea level) has two permanent ones of oligosaprobic character, differing considerably from one another by their physiognomy. Physico-chemical properties of both tributaries were similar, but tributary 1 showed smaller variations in the parameters studied. In both tributaries, benthic macrofauna consisting of 38 taxa was rather poor (Si = 56%) with Amphipoda as dominant representatives. The average yearly abundance of macrozoobenthos in tributary 1 and 2 was .hivin.x = 15 582.7 and .hivin.x 5 44.93 n m-2, respectively. Based on the occurrence of Amphipoda and Isopoda, a marked migration in the winter period can be presumed.
