张家口坝上高背型鲫鱼耗氧率和窒息点的初步研究
Preliminary Study on Oxygen-consuming Rate and Suffocation Point for High-backed Carassius auratus from Bashang in Zhangjiakou
摘要
Abstract
The oxygen-consuming rate and the critical suffocation point have been determined for two sizes of the high-backed Carassius auratus. The results showed that under the conditions of water temperature at 24.9-33.0℃, the small size fish, with average length of 76.1 mm and average weight of 7.56 g. had the average oxygen consumption of 0.22 mg / (ind · h) within 24 hours, and the oxygen-consuming rate was 0.029 mg / (g · h). and the suffocated point was 0.03 mg / L. Under the conditions of water temperature at 12.4-13.4℃, the large size fish, with the average length of 153.0 mm and the average weight of 53.43 g, had the average oxygen-consuming of 0.51 mg / (ind · h) within 24 hours, and the oxygen consumption rate was 0.010 mg / (g · h). and the suffocation point was 0.02 mg/L. The oxygen-consuming rate of the high-backed C. auratus varied significantly from day to night, and it was higher at daytime than that at night, and two peaks of the oxygen-consuming rate appeared at daytime. The fish had an extremely low suffocation point and could survive the extreme oxygen-deficient The time-consuming of achieving the suffocation point was closely related with water temperature.关键词
