Abstract: The Macrobrachium lamarrei lamarrei is a small prawn widely distributed all over India and has commercial importance. The freshwater prawn Macrobrachium lamarrei lamarreiat different duration (0.002 mg/l HgCl2 for 20, 40 and 60 days) of exposure of mercuric chloride observed such as, absence of glycogen content, loss of clear cell junction and dysplasia in B-cells. In case of R-cells development of numerous granular inclusions in lipid vacuoles and cell cytoplasm and F-cells show dilated rough endoplasmic reticulum and dilated cisternae of Golgi bodies.
