Abstract

Opacity of eye was confined to Mugil cephalus only (23.2%) while fin erosion was observed in several species-Liza macrolepis (36.1%), Rastrelliger kanagurta (39.1%) and Sardinella longiceps (63.4%) including M. cephalus (20.3%) from harbour waters of Visakhapatnam. The presence of pollutants in form of heavy metals, and oil and grease at toxic concentrations might be the cause for these abnormalities.
