Evaluation of Toxic Effect of Clerodendrum inerme leaf extract on catfish, Heteropneustes fossilis
Dr. T. S. Naqvi
Abstract :
One hundred forty four hours of toxicity test was conducted to observe the lethal concentration (LC50) value of Clerodendrum inerme leaf extracts on Heteropneustes fossilis. The fishes were exposed to seven different concentrations of the extract (20 mg 1–1, 40 mg 1–1, 50 mg 1–1, 60 mg 1–1, 70 mg 1–1, 80 mg 1–1 and 90 mg 1–1) for toxicity test and one remained as control. The LC50 value of C. inerme in H. fossilis was found to be 60 mg 1–1 for 144 hours exposure periods. Analysis of variance for the effect of the extract on the percentage mortality of fish showed a significant relation between both the factors (p<0.05, F=14.42). The correlation coefficient between concentration and mortality of fish was calculated (R = 0.814) and showed a strong positive correlation between different concentrations of the leaf extracts and mortality percentage of fish. The present finding established that C. inerme has potential toxic effect on fish and could be use widely to control undesirable fishes.
