Abstract

 Present study was carried out on Zayandeh-Rud River, in a 30km distance downstream the Koohrang water supply tunnel to Sudetjan Bridge, all located in Charmahal province during 2008-2009. 6 study stations were determined and river benthic MACROINVERTEBRATES were monthly collected using a Surber sampler (1600 cm2, 250mmesh). According to the results, a total of 31 benthic taxa including 22 aquatic insect larvae (11 EPT or sensitive taxa) and 9 other groups such as worms and Gammarids, were identified. Individuals belong to Ephemeroptera and Diptera were dominant in most study sites except for station 2 (Cheshme Dimmeh), which Gammarids had dense population over there. Among sampling sites, station 3 just after a 200 metric tons rainbow trout farm effluent, had the highest taxa richness and the subsequent stations had more EPT richness. Comparing the HILSENHOFf family level biotic index at different stations reveals that a remediation of water quality occurs downstream the effluent receiving point and are classified as "good" water quality (HBI: 4.2-4.8). Organic materials and nutrients coming both from river catchment's area and human activities such as fish farms and adjacent agricultural lands in addition to own life span of macrobenthic animals, seems to be the main determinants of fluctuation in community structure of MACROINVERTEBRATES fauna in Zayandeh-Rud River.
