Abstract

Zinc is an important trace element
involved in enzymatic functions like protein
synthesis and carbohydrate metabolism
(Hammond and Beliles 1980). However, it
becomes toxic when exceeds the critical
level. Acccffding to Hodson (1976), the effect
of toxicity of heavy metals increases with
increase in concentration and exposure time.
This study has been done to understand the
degree of adaptability of fish Oreochromis
mossambicus in different exposure periods
to zinc toxicity. The ameliorating effect of
salinity on acute zinc toxicity to the fish has
also been studied during different exposure
periods.
