Abstract
Fresh water fish, Oreochromis mossambicus was exposed to Electroplating effluent with
a view to check the histopathological changes as a function of effluent concentration.
Increase in concentration always produced the structural damage observed in the gills,
intestine and stomach illustrates metal toxicity on the aquatic organisms. The lifting of
gill lamellae, necrosis, structural deformities in the epithelial cells, gill fusion, intestinal
wall shrinkage, epithelial eruption etc identified in this study. Hence a well pretreatment
is obligatory for the discharge of electroplating effluent.
