MODULATION IN RESPIRATORY DYNAMICS OF THE ESTUARINE CLAM, Katelysia opima (Gmelin) UNDER SUBLETHAL AND LETHAL STRESS OF CADMIUM CHLORIDE | UTTAR PRADESH JOURNAL OF ZOOLOGY
The present study was conducted to find out effect of lethal and sublethal concentrations of CdCl2, 2½ H2O for 96 hrs. Static Bioassay Tests were conducted to find out LC0 and LC50 values for summer, monsoon and winter of 2018/19. The data was analyzed by Finney’s probit chart analysis method to calculate LC50 and 95% lower and upper fiducial limits. These predetermined values for cadmium chloride concentrations were used for exposure to LC0 and LC50 group of clams. Experiments were conducted during summer, monsoon and winter by maintaining control group of clams. Estuarine water parameters like temperature, pH, salinity, rainfall and oxygen saturation were recorded. In the present study, it was found that, cadmium chloride has significant influence on rate of oxygen consumption. During summer, clams from LC0 and LC50 group were treated with 0.8 and 1.3 ppm cadmium chloride, while in monsoon these values were 1.1 and 1.6 ppm respectively. During winter, clams from LC0 and LC50 group were exposed to 1.0 and 1.8 ppm cadmium chloride respectively. Please read full article - http://mbimph.com/index.php/UPJOZ/article/view/1516
