This study was performed in Neka Power Plant during one year and started in March 1991, to survey on the effect of Neka Power Plant on the environment and the possibility of fish Farming by use of outlet water. For this purpose the water sampling has been done each month for chemical analysis. The primary sampling and survey showed that the outlet water contained human and industrial Sewages. The difference between water temperature in outlet water and the Caspian Sea was 1OºC and the amount of free chloride in outlet water varied between 0 and 6.8 mg/lit and 300 kg ferros sulphate was daily injected into water per unit or Power Plant. The plankton and bentos organism were identified at the determined stations, which their abundance is different from other spots of the sea. The mortality ratio of fishes were estimated which was caused by chloride injection into water, the difference in water temperature and pressure increasing. The average fish mortality was estimated 96 units, in one.....
