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

摘要

Effects of Zn and Cd on condition factor (CF), hepatosomatic (HES) 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.
