Behaviour of Heteropneustes fossilis under Stress of Thiodan Toxicity
The freshwater catfish, H. fossilis, exposed to the 96 h‐LC50 (0.007 … 0.013 ppm) of the organochlorine thíodan (endosulfan) for 4 days, developed behavioural anomalies within 30 min of exposure. Increased opercular movement rate, greater frequency of surfacing for gulping air, restlessness, aimless wandering, tendency to move individually instead of in groups, lethargy and disoriented locomotion were commonly observed and became marked by the end of 12 h of exposure. Subsequently, some individuals tended to recover while others developed uncontrolled, continuous and irreversible contortions and died.
