Abstract

This study was carried out about 15 months to determine suitable locations for the development of aquaculture across the Gamasiab river of Hamedan province in 2007 - 2008. Physicochemical parameters and macro benthic invertebrates fauna 15 and 13 stations respectively every 45 days and seasonally fish identify in 8 stations were performed according standard methods. The average water temperature was 12.8±3.7 oC, minimum and maximum dissoled oxygen were 2.6 and 12.5 mg/lit respectively during the study. The pH range was between 7.5-8.8 , the minimum and maximum Ec was 250 and 750 µmos/cm in Mehr and Tir. The transparency range was recorded about 1-103 F.T.U. The uder factors such as amount of suspended materials: 0.01-0.1 mg/l, amount of BOD5: 0.05-6.2 mg/l and COD: 30 (minimum) and 70.57 (maximum) were recorded. The total solids material (T.S.S) were less than 1 mg/lit. Totally 37 groups of bentic organisms were identified which 11 groups of them were appertained to pollution sensitive orders containing Ephemeroptera, Trichoptera and Plecoptera. During fish population studied 21 species belonging 5 family were identified. Based on obtained results of biological, ecological, economic and social parameters, 10 sites in 7 areas were suitable identified for fish rearing and 12 aquaculture programs (10 plan for fish rearing and 2 plan for increasing fish production of (Oncorhynchus mykiss). The minimum and maximum production capacity in mentioned places was estimated about 1675 and 3850 tons respectively.
