The correlation between some water ionic and nonionic parameters with heamatocrite indicator, growth and survive of common carp in culturative ponds

For evaluation of cultural common carp some water physicochemical aspect including ionic composition (Na+, K+, Ca2+ and Mg2+) and organic (total protein, glucose and cholesterol) and their correlations with heamatocrite indicator, growth and survive within 7 months on 15 ponds (10 hectar) in Dikjeh area of Gonbad in Golestan province in iran were investigated. The range of water ionic composition were included (0.99-26.30 Mmol/1) Na+, (0.60-14.20 Mmol/1) K+, (0.68-24.62 mgr/dl) Ca2+ and (0.87-12 mgr/dl) Mg2+, also the ranges of water organic composition were measured (0.2- 0.73 gr/dl) total protein, (0.86-85.41 mgr/dl) cholesterol and (0.68-105.8 mgr/dl) glucose. The results of pearson were showed that there were significant correlation between water Mg2+ with length, weight (PO.Ol) and fish biomass (P<0.05), Ca2+ with weight and fish biomass (P<0.05), Na+ with length and weight of fish (P<0.01), K+ with fish biomass (P<0.05), total protein with length, weight (PO.Ol) and fish biomass (P<0.05), cholesterol with heamatocrite (P0.05) and water glucose with length (P<0.05) and weight of fish (PO.Ol). So, between water ionic and nonionic parameters with growth and survive significant correlation was showed. There for with management and regulation this factors in suitable culture range are caused growth and survival increasing in common carp.
