The estuarine clam, Meretrix meretrix was exposed to predetermined seasonal sublethal and lethal concentrations of CdCl2, 2½ H2O for 96 hrs. Experiments were conducted during summer, monsoon and winter by keeping control group of clams. Estuarine water parameters like temperature, pH, salinity, rainfall and dissolved oxygen were recorded. In the present study, it is found that, it has significant influence on rate of oxygen consumption and toxicity of cadmium chloride. During summer, clams from LC0 and LC50 group were treated with 1.1ppm and 1.8 ppm respectively. During monsoon LC0 and LC50 group were treated with 1.6 ppm and 2.0 ppm respectively. During winter clams from LC0 and LC50 group were exposed to 1.4 ppm and 2.1 ppm cadmium chloride respectively. During summer, as compared to control group, there were 3.83, 17.04, 16.77 and 10.63% increase in oxygen uptake at the end of 24, 36, 48, and 60 hrs. There were 0.35, 4.97 and 21.75% decrease at the end of 48, 72, 84 and 96 hrs. Moreover, similar trend of oxygen consumption was observed in LC0 and LC50 .group of clams in winter and monsoon season. During monsoon and winter clams from control group showed similar trend of oxygen uptake with less significant fluctuations. Clams from control group and LC0 and LC50 group showed less oxygen consumption during monsoon than summer and winter.
