对两种规格黄颡鱼的耗氧率、耗氧量及窒息点进行了测定。结果表明,黄颡鱼的耗氧率随体重增加而降低,而耗氧量和窒息点随体重的增加而上升。平均体长9.43cm、体重16.58g的黄颡鱼的耗氧率为0.1264mg/g.h,耗氧量2.0946ml/尾·h,窒息点0.398mg/L;平均体长7.16cm、体重7.07g 的黄颡鱼的耗氧率为0.1533mg/g.h,耗氧量1.0841mg/尾.h,窒息点0.208mg/L。
The oxygen consumption rate, oxygen consumption rate and asphyxia point of two kinds of yellow catfish were measured. The results showed that the oxygen consumption rate of yellow catfish decreased with body weight gain, while oxygen consumption and asphyxia point increased with body weight gain. The average body length of 9.43cm, body weight 16.58g yellow Oxya fish oxygen consumption rate was 0.1264mg / gh, oxygen consumption 2.0946ml / tail · h, suffocation point 0.398mg / L; average body length 7.16cm, body weight 7.07g Catfish oxygen consumption rate of 0.1533mg / gh, oxygen consumption of 1.0841mg / tail. H, suffocation point 0.208mg / L.
