The acute toxicity test was performed for 4 days in which two replicates of seven different Zn concentrations (0, 10, 40, 70, 100, 130, and 160 mg/L) were used (10 fish for each aquarium). At 24, 48, 72, and 96 h, fish dead were counted in the different Zn concentrations along with the control group.
