ABSTRACT

 

The wide array of pollutants discharged into aquatic environment may affect over physicochemical, biological, toxic and pathogenic to aquatic ecosystem. The present work describes the effect of physico-chemical parameter on the functional morphology of hepatopancreas of crab Barytelphusa cunicularis. We have carried out the morphological and functional state of hepatopancreas in Barytelphusa cunicularis. Physico-chemical parameters such as pH, Temperature, Dissolved Oxygen, Free Carbon dioxide, Hardness, Chemical Oxygen Demand, Chloride, Alkalinity, Nitrate, Phosphate and base level contamination of heavy metals was evaluated. Histologically hepatopancreas consists of F- cells, R-cells and B- cells investigated by using standard H-E (Hematoxylene-Eosin) staining technique. Histopathological changes were comparatively discussed in relation to pollution status. Data indicated that pollutants were the main cause of pathological symptoms. Finally it could be concluded in histological changes in crabs can be taken as biomarkers for monitoring pollution in aquatic bodies.
