| 摘 要： | 实验测定了不同温度、不同规格大鳞鲃(Barbuscapito)的耗氧率和窒息点。水温16～34℃范围内,大鳞鲃1龄鱼(24.78±2.19)g]和2龄鱼(185.94±5.53)g]的耗氧率和窒息点随温度的升高都表现出上升的趋势。水温26℃时,随着体重规格(10 g、30 g、180 g)的增大,大鳞鲃的耗氧量逐渐升高,耗氧率逐渐下降。1龄大鳞鲃(34.61±3.75)g]白天的耗氧率显著高于夜间耗氧率,白天12:00～14:00最高,平均耗氧率为(0.195 8±0.037)mg/(g.h),夜间22:00～24:00最低,平均耗氧率为(0.145 9±0.029)mg/(g.h)。测得1龄大鳞鲃在水温26～32℃时的窒息点为0.180 5～0.525 2 mg/L,2龄大鳞鲃的窒息点为0.292 1～0.588 8 mg/L。

| Abstract: | Oxygen consumption rate and suffocation point of Barbus capito with different temperature and body weights were measured.The oxygen consumption rate and suffocation point of 1year and 2-years Barbus capito increase respectively as water temperature go up under a range of 16-34 ℃.It is demonstrate that oxygen consumption is moving up and oxygen consumption rate is dropping down gradually as body weight under a range of 10-180 g at 26 ℃.The average oxygen consumption rate of 1-year fish in the day is significantly higher than that at night.The highest value appears between 12:00 and 14:00 on an average of(0.195 8±0.037) mg/(g·h),the lowest one appears between 22:00 and 24:00 on an average of(0.145 9±0.029) mg/(g·h).The suffocation point are respective 0.180 5-0.525 2 mg/L and 0.292 1-0.588 8 mg/L for 1-year fish and 2-years fish under a range of 26-32 ℃. |
