The effect of sublethal levels of copper and cyanide on some biochemical parameters of rainbow trout along subacute exposition

1. The stress responses of juvenile rainbow trout (Oncorhynchus mykiss) sublethally exposed to copper and cyanide was studied. 2. Copper and cyanide caused rapid elevations (p < 0.0001) of plasma cortisol levels (185ng/ml for copper, 305 ng/ml for cyanide) observed in 1 hr and maintained throughout the experiment. 3. Cholesterol in both exposed groups showed increases for the first 15 days and decreases at day 21. 4. Different time evolution in the control and in the treated group was observed. 5. Plasma sodium only showed a significant decrease (p < 0.001) from 1 to 7-15 days of copper exposure. © 1991.
