实验温度(26.1±0.5)℃,试验鱼平均体长10.60 cm,平均体质量13.09 g。丁鱥耗氧率为0.0849mg/(kg.h),窒息点为0.7598 mg/L。丁鱥的耗氧率呈明显的昼夜变化,白天平均耗氧率为0.0585 mg/(kg.h),夜间平均耗氧率为1.1161 mg/(kg.h)。丁鱥的耗氧量随着体重的增加而增加,耗氧率随着体重的增长而减小。在一定水温范围内,耗氧率随着水温的上升而增大。
The experimental temperature (26.1 ± 0.5) ℃, the average body length of test fish 10.60 cm, the average body mass 13.09 g. Ding 鱥 oxygen consumption rate of 0.0849mg / (kg.h), suffocation point 0.7598 mg / L. The oxygen consumption rate of Dingxian showed obvious diurnal variation, with the average day oxygen consumption rate being 0.0585 mg / (kg.h) and nighttime oxygen consumption rate being 1.1161 mg / (kg.h). Ding 鱥 oxygen consumption increases with weight gain, oxygen consumption rate decreases with the weight gain. In a certain water temperature range, oxygen consumption rate increases with the rise of water temperature.
