Bio accumulation of Heavy metals and associated histological changes in the gonads and morphological changes in Gills and fins of Liza parsia from Asthamudi wetland, the Ramsar site

The present study highlights the bioaccumulation of heavy metal and subsequent changes in the estuarine fish Liza parsia from Ashtamudi lake. The results of the present study on the quality of water and various aspects of L. parsia proved the grave situation of the lake. Morphology, biological constituents and reproductive organs of the fishes are greatly affected due to the pollutants. It will directly as well as indirectly affect the human being through the food chain. If the quantum of pollution status of the lake persists like this or increases, the quality of water, fishes and other biota of the lake will get deteriorated at a greater magnitude, becoming a serious threat to mankind.
