Description:
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 fauna15 and 13 staitions 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 recirded. 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 pollutionsensitive
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 (Onchorhynchus mikiss).The minimum and maximum production capacity in mentioned
places was stimated about 1675 and 3850 tons respectively.
