Abstract: The oxygen consumption rate and asphyxiation point of Channa asiatica are studied preliminarily.The results are as follow. ( 1) The oxygen consumption rate of Channa asiatica increases with water or air temperature rising and with its weight dropping, whether in water or in air. ( 2) The fish's average oxygen consumption rate in the night is a litter higher than that in the day. ( 3) The asphxiation point of Channa asiatica increases with water temperature rising and drops with its weight increasing. ( 4) The air-respi ration is important in the respiratory function of Channa asiatica.

Key words: Channa asiatica, oxygen consumption rate, asphyxiation point
