Abstract :

Abstract[1] This study, at the time of releasing kutum (Rutilus frisii kutum) fingerlings in two Tajan River and Surkh Rud leading to the Caspian Sea for protect survival and investigated water quality was carried out with aim survival suitable and the health releazed fishes. Physico-chemical parameters of water and organochlorines pesticides were studied and compared in the range of two river estuaries from May to September. In each of river were taken three stations respectively in estuaries, location of the release kutum and upstream the water were sampled. The results showed that the electrical conductivity, total dissolved salts, salinity, ammonium, calcium, magnesium and total hardness as CaCO3 in the water Surkh Rud and Tajan River the release of kutum fingerlings is statistically significant (p < 0.05). Mean values of factors: water and air temperature, pH, dissolved oxygen water, biological oxygen, phosphate, nitrite, nitrate is not statistically significant (P>0.05). The results investigation on water in period of release of kutum fingerlings in Surkh Rud and Tajan River some organochlorines pesticides were observed, including: Aldrin, DDD, d-BHC, b-Endosulfan, Endosulfan sulfate, Heptachlor, Lindane. Values measured in these rivers the concentration changes from 0.10 to 0.22 in micrograms per liter. Overall, results showed that more suitable Surkh Rud to the Tajan River water parameters were to release and life the kutum fingerlings.   * Corresponding Authors; Email: [e-mail]
