Abstract

The median lethal concentration of mercury for 96 hr was 0.06 ppm for the fish Oreochromis
mossambicus. Test animals \ ere exposed to sublethal concentrations of mercury (0.01 and 0.02 ppm) for
4 weeks (exposure period). They were transferred to metal impoverished water for another 4 weeks
(recovery period). The growth of the test animals was estimated weekly throughout the experimental
period. Protein, carbohydrate and lipid contents were also estimated in tissues of muscles, liver and gill.
Significant reduction of growth and biochemical components was observed during exposure period and
the loss was regained up to certain extent during recovery period.
