AbstractThe current study examined seasonal variations in the blood coagulation time of Heteropneustes fossilis in both sexes from January to December 2022. Notable were the greatest and minimum coagulation times in the months of December and June, as well as the non-significant variation in coagulation times between the sexes. It was also observed that the clotting time increased gradually from January to June and then steadily decreased from July to December. The fish’s blood clotting time may gradually increase and drop due to a series of increases in ambient temperature from January to June and a gradual decrease in temperature from July to December.

Key words: Coagulation, Heteropneustes fossilis, Temperature, Seasonal Variation, Blood.
