Comparison of water quality parameters of the Samsami and Dinaran rivers with water quality standards for trout culture
Water quality of the Samsami and Dinaran rivers of Chaharmahal and Bakhtiari province were assessed in year 1393. For each river, 7 stations were determined. Water sampling has been done monthly (May to October) and samples, under standard situation, were sent to laboratory for assessing: Nitrite, Ammonium, Soluble Phosphate, BOD5, COD, TSS, TDS, Cu, Zn, Hg, Cl-, Organophosphate toxins, pH, Malachite green and EC. Soluble phosphate was higher than standard in studied rivers (p<0.05). There were increasing trend for all recorded parameters from first to last station. Except for the low number of stations, BOD5 and COD were equal or lower (p<0.0001) than its standards. There were some malachite green in studied rivers especially at their last station (p<0.002). Other parameters were lower than standard for two rivers (p<0.05). Generally, water quality of these two rivers was absolute, but, for development new trout culture farms, Nitrite, Phosphate and Malachite green must be controlled.
