Rivers are considered to be among the most significant sources of fresh water, and their quality monitoring holds significant importance in terms of both spatial and temporal changes. In this study, the water quality of Golin River was investigated using the CWQI index for the construction of warm and cold-water fish breeding centers. Different parameters as: DO, pH, BOD5, NO3, Ec, turbidity, temperature, TDS, CaCO3, NO2, total hardness, CO2, Cu, NH3, and Fe were sampled twice a month from the water from April 2019 to March 2020. The results showed that the parameters of BOD5, TDS, CaCO3, NH3, Cu, and NO3 were in the unfavorable category in comparison with the standards of hot and cold-water fish farming. Comparison of CWQI index in cold-water fish farming in different months showed that the highest and lowest numerical values of the index with values of 70.02 and 60.37 were observed in February and December, respectively. Also, the numerical values of the index in warm-water fish farming were observed as the highest and the lowest numerical values of the index with the values of 85.38 and 70.96, in April and February, respectively. The results of this study showed that according to the final value of CWQI index, in general, the water of Golin river was suitable for warm-water and cold-water fish farming in the desired range.
