Abstract
In this study the correlation between water physicochemical (EC, pH, salinity, hardness) and ionic (Na+, K+, Ca2+ and Mg2+) parameters with growth indicators in Rutilus frisii kutum within 3 months on 7 ponds (2 hectar) in Sijoval area in Golestan province were investigated. The range of water ionic composition were included (230-447.5 Mmol/l) Na+, (11.5-28.8 Mmol/l) K+, (0.04-22.44 mgr/dl) Ca2+ and (12.47-22.45 mgr/dl) Mg2+. The pearson results were showed that there were significant correlation between first weight with Na+ and salinity (p<0.05), growth ratio with second weight (p<0.05), water pH with k+, Na+, Mg2+ (p<0.01) hardness with hardness, Na+ and Ca2+ (p<0.01), salinity with k+ and Na+ (p<0.01) and Na+ with K+ (p<0.05). So, between water physicochemical and ionic parameters with growth indicators, significant correlation was showed that with management and regulation these factors in suitable culture range, are caused growth increasing in R. frisii kutum.
