Abstract

Cheshmekile River in the southern Caspian Sea is an important and valuable habitat for migrating species and birth collect valuable fisheries such as salmon trutta caspius and Rutilus frisii kutuIn. In the present study, to assess the quality of river water Cheshmekile TONEKABON in the year 1389-1390 based on macroinvertebrates fauna River studies at four stations within twelve sampling intervals with surber level 0.1m2 and three replicate were performed. The study of 47 families belonging to 15 order and six category macroinvertebrate in the River was identified. Indicator of biodiversity in the River is among the highest diversity of aquatic insect larvae simultaneous sampling benthic some of physical and chemical factors such as water temperature of BOD5 and TDS were measured at stations that the above factors in the stations were significantly different at 0.05. Probability level (p>0.05) did not show. Results show that the order Diptera and Ephemeroptera were organismsat all stations. Maximum abundance of organism at this time to a station 1 with 44% and minimum of 16% were related to the station 4.Kruskal Wallis test order index invertebrates order Plecoptera, Trichoptera, Ephemeroptera, Other in stations throughout is the year indicators a significant difference between the confidence level of 0.05 (p<0.05) but the family Chironomidae at four stations during the year showed no significant difference between stations. The investigation showed that the minimum mean EPT/CHIR owned station 4 with 0.79 and the maximum is 3.32 to station 1. Based on BIOLOGICAL INDICATORS Hinselhof (HFBI) during the years the station 1 has a very good quality condition, station 2 has a status of good quality, and station 3 has a with an average of stations 4 and the conditions were relatively poor. Results showed that the four stations due to pressure from domestic and municipal sewage and wastewater, machine shops, laundering, branch fish sales and discharge of urban waste in the river with a high pollution load sand and gravel plants, legal and illegal removal of sand from the river bed is relatively weak in terms of seasons creates.
