EFFECTS OF ZINC AND CADMIUM ON CONDITION FACTOR, HEPATOSOMATIC AND GONADOSOMATIC INDEX OF Oreochromis niloticus

Effects of Zn and Cd on condition factor (CF), hepatosomatic (HIS) and gonadosomatic (GSI) of Oreochromis niloticus, after exposing the animals to 10 % of their LC50 values, namely 6.0 ppm Zn and 1.6 ppm Cd, over 7, 15, and 30 days. Standard mathematical formulations were used in determining the men...

description Effects of Zn and Cd on condition factor (CF), hepatosomatic (HIS) and gonadosomatic (GSI) of Oreochromis niloticus, after exposing the animals to 10 % of their LC50 values, namely 6.0 ppm Zn and 1.6 ppm Cd, over 7, 15, and 30 days. Standard mathematical formulations were used in determining the mentioned parameters. Cadmium, which is a toxic metal, increased GSI and decreased HSI and CF at the beginning of the experiments. The decrease in HSI and CF continued with increasing exposure periods. Zinc, however, decreased all three parameters compared with control at the end of experiments (P
