Abstract

Benthic Fauna study was conducted in four rivers (Dalichahi, Absefid, Elarm and Kamardasht) that leading to LAKE RESERVOIR behind the LAR DAM in 12 smpling larintervals and sampled monthly during June to October in the years 2009 and 2010. Samples were conducted using the Sorber (dimensions 40´40 cm square) in the four stations of the rivers with three replications. Samples collected and fixed by 4 percent formaldehydesolution then after isolation in the laboratory, the benthos were identified and counted. According to results 15 Order of Benthic were identified, among them anaquatic insect larvae had greatest diversity. species belonging to two orders Diptera and Ephemeroptera were the dominant organisms at all stations are. Mean total density and biomass were 13104 /m2 and 70.62 g/m2 respectively. The above Order had 85 genus and species. Order Diptera with a mean frequency of 10234 /m2 (60.22 gr/m2) in the first rank, and then orders Ephemeroptera with a mean frequency of 1680 /m2 (2.33 gr/m2) was the second highesity. The Most Macrobenthos order was Diptera with frequency in the month Jully total number of 2569. Based on Kruskal-Wallis test except the insects, in terms of abundance and biomass, has had a significant difference (P<0.05). Density at different depths within the sediments studied organic mater rates in sediments, a high correlation (R=20.92-0.98) was observed. The amount of organic matter in sediments at different depths in the summer with another season of the year showed a significant difference (P<0.05). there was no statistically significant difference in Total Macrobenthos biomass between 4 stations in the river, However, the abundance of organisms in the stations were significant different (P<0.05).
