Cytopathological changes of gills and muscles in Asian sea bass, Lates calcarifer (Bloch) exposed to mercury


D Usha, A Maharajan, V Ganapiriya, SM Fazildheen

Heavy metal concentrations of mercury and the associated structural deformities in the gills and muscles of Asian sea bass, Lates calcarifer were observed for sublethal toxicity studies. Cytopathological alterations in gill tissues displayed oedema of epithelial cells, ballooning dilation, partial epithelial lifting, and damaged pillar cells; the muscle displayed shortening of muscle bundles, oedema and necrosis, atrophy of muscle bundles, and vacuolar degeneration in muscle bundles; The present study demonstrated that all the treated body tissues exhibited significant damage with response; among the body organs, the liver and brain are important target organs for mercury toxicity in L. calcarifer, which suggest that biomarkers are useful in assessing the model organism for toxicity studies.
