Study ionic and non ionic factors of blood in kutum (Rutilus frisii kutum) emigrant to Tajan River

During four month، amounts of ionic (sodium، potassium، magnesium and calcium) and non ionic parameters (cholesterol، total protein and glucose) in female kutum blood in Tajan river estuary were determined. Also correlation between them was investigated. Sodium، potassium، calcium and magnesium were maximum to minimum respectively and concentration of cholesterol was more than glucose and glucose was more than total protein. The correlation between sodium and magnesium (P<0. 01) was significant، but this correlation with glucose (P<0. 01) and pH (P<0. 05) was invert. There was a significant correlation between calcium and total protein (P<0. 05). The correlation between magnesium with sodium to potassium ratio and calcium to potassium ratio was significant (P<0. 05) but correlation between ion with pH (P<0. 01) and glucose (P<0. 05) was invert. The correlation between calcium with total protein (P<0. 05) and also between sodium to potassium ratio and calcium to potassium ratio (P<0. 01)، was significant. According to influence of ionic and nonionic blood’s plasma on regulation of pH reproduction and growth in kutum، we can use this result in management of reproduction and culture of this valuable species.
