| Abstract | ||
| Kurdistan province is one of the most important provinces in Iran in terms of surface and underground waters, and the Garan resevior (Marivan) has important rules in aquaculture and fisheries activities. For this purpose, the present study was carried out including a survey of 22 physico-chemical parameters at four sites of Garan reservoir from July 2017 to August 2018. Results showed that the mean value of water temperature 11.13 ± 6.7 °C and the Dissolved Oxygen (DO) concentration was 8.44 and 3.87 mg/l for surface and deep layers respectively. Based on the results, was shown that the Thermocline and oxycline start from June and they vanish in December as well as. Mean of pH value 7.99 and secchi disc depth was high (2.3 m) relatively. Also the mean value of alkalinity, Biochemical Oxygen Demand (BOD5), Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), Total Dissolved Solids (TDS) and electro conductivity 138.59, 1.32, 25.02, 0.047, 156.91 mg/l and 242.18 (μmhos/cm) respectively. Also mean of nutrients were within desirable limits. In general, although seasonal and spatial variations were observed in some parameters, but according to the results of physico-chemical characteristics, the Garan reservoir could be considering suitable for standard pattern of aquaculture activities. | ||
