EFFECT OF SUBLETHAL TOXICITY OF ZINC CHLORIDE ON LIVER HISTOLOGY OF ESTUARINE EDIBLE FISH, LIZA MACROLEPIS (SMITH, 1846)

In the present study, estuarine edible teleost, Liza macrolepis of size 9.6 ± 1.2 cm length were exposed to sublethal concentration (1/10 of LT50/96 h) of heavy metal, Zinc chloride for a period of 15 days. The treated fish groups were compared with the control group for histopathological changes in the liver tissue. The histopathological changes occurred in the liver of L. Macrolepis suggest that histopathological studies are considered as direct evidence referring to any adverse effect on fish health. Moreover, the liver is considered as the principal target organ of detoxification in vertebrates and particularly in fish
