Abstract

In the present investigation. we examined the effects of heavy metals on formation of lipofuscin, in the hepatopancras of the penaeid shrimp Metupc.noe[t~cl ob.~on(i Miers), exposed to culture medium containing 0.0.5 and 0.15 ppm copper and 0.005 and 0.015 ppm mercury. Impact of mercury on lipofuscin accumulation is found to be rather limited. Intensity of lipofuscin is much more in the case of copper exposed animals. It is more so in animals exposed to 0.05 ppm of copper as the epithelial cells in the middle and proximal region of the tubules seem to be heavily laden with lipofuscin granules. The increase is noticed not only in the number of granules but also in the size. The distal tubular region with practically no secondary or tertiary lysosomes is devoid of lipofuscin granules.
