      The rates of air breathing ofColisa fasciata were recorded at 5°; C interval over a temperature range of 20–40° C. The air breathing rate increased with the temperature. This was attributed to increase in the metabolic rate and the muscular activity (general restlessness), both of which make heavy demands of oxygen. Coupled with these, the decline of oxygen-holding capacity of the water at higher temperatures leave the fish with no option but to increase its dependence on the atmospheric oxygen and hence the rise in the air breathing rate. Increase in the temperature was also characterised by decrease in the time of asphyxiation when the fish was prevented from coming to the surface and gulping the air.
