Abstract Pesticides get easily dissolved and transported in water to be readily taken up by the aquatic biota. It reaches the food chain causing various physical, biochemical and morphotoxicological changes. Fish are important source of food so, it is essential to protect the health of fish population. In the present investigation adult live specimen of marine edible fish Lepturacanthus savala were caught from the Khar-Danda sea coast. When the fish were exposed to two sub lethal concentration ie 1/10 or 2.5 % and 1/5 or 5% of the two pesticides, Rogor technical grade 30% EC., and Sevin 36% w/w (active ingredients) on different aspects of Ribbonfish,(length:65.2�1.25cm and weight 130.5�0.5gms) like survival behaviour, food intake, growth and mortality, it showed remarkable changes. In comparison to control the sub lethal effects of these pesticides led to decrease in the survival rate with the increase in concentrations. Respiratory disruption was observed as coughing and yawning because of toxic stress. There was decrease in the amount of food intake of the treated fish as compared to control. The weight, length and breadth showed a decreasing trend in both the concentrations of pesticides though there were variations in weight in terms of growth in the pesticides treated fish. Higher percentage of mortality occurred with the increase in concentration and exposure period.
