Abstract: This research was conducted to determine the effects of dietary bentonite on copper toxicity in rainbow trout (Oncorhynchus mykiss). Fish were fed with a commercial feed including 0, 500 and 1000 mg/kg Cu and 0, 1 and 2% bentonite for 4 months. Final evaluation was made by determining hematology and enzyme activities. It was determined that bentonite did not prevent the toxicity of fish in the presence of 1000 mg/kg copper since there were significant changes in enzyme activities of fish. It may be suggested that adding 2% bentonite to fish feeds prevents Cu toxicity. Further studies are needed in different fish species living various environments in order to introduce it commercially.
