【摘要】 对月鳢的耗氧率和窒息点进行了初步研究 ,结果表明 :( 1 )无论是水呼吸还是气呼吸 ,月鳢的耗氧率均随试验鱼个体增大而降低 ,随水温或气温的升高而升高 ;( 2 )月鳢夜间的平均耗氧率略高于白天平均耗氧率 ;( 3)月鳢的窒息点也是随鱼体增大而降低 ,随水温升高而升高 ;( 4 )气呼吸在月鳢的呼吸活动中占有较重要的位置 .更多还原

【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-respiration is important in the respiratory function of Channa asiatica .更多还原
