Abstract

Lipid peroxidation and the consequent formation of lipofuscin granules have got extremely high importance in heavy metal homeostasis. Lipid peroxidation in fish is found to be an adaptation to internally detoxify and thereby safely assimilate the intruding metals. Though these are of fundamental importance in heavy metal homeostasis, they leave an unfavourable alteration in the physiology of lysosomal lamina. This is evidenced by an increase in the thiobarbituric acid value in fish exposed to mercury. The present study confirmed the efficiency of the aqueous extracts of Ocimum sanctum, Azadirachta indica, Murraya koenigii and Vitex negundo administered through the feed to mercury-exposed Oreochromis mossambicus in alleviating the deleterious effect of the heavy metal.
