摘 要 ：目的:研究宽体金线蛭的耗氧率和窒息点。方法:应用呼吸室法进行研究。结果:平均体重为10 g的宽体金线蛭,15~35℃变温下耗氧率为0.049~0.094 mg.g^-1.h^-1,耗氧量为0.44~0.67 mg.p^-1.h^-1,窒息点为0.9~1.51 mg.L^-1;20℃条件下耗氧率为0.044~0.058 mg.g^-1.h^-1,耗氧量为0.19~0.77 mg.p^-1.h^-1,窒息点为1.4~1.57 mg.L^-1。结论:宽体金线蛭的耗氧率随水温的升高而上升;窒息点与温度和体重呈负相关;体重与耗氧率呈负相关,与耗氧量呈正相关;耗氧率白天和夜晚的差异不大。

Abstract:Objective: To study the oxygen consumption rate and suffocation point of Whitmania pigra.Method: Using the method of respiratory chamber,the oxygen consumption rate,oxygen consumption volume and suffocation point were obtained.Result: The oxygen consumption rate(OCR) ranged from 0.049 to 0.094 mg·g^-1·h^-1,the oxygen consumption volume(OCV) from 0.44 to 0.67 mg·p^-1·h^-1,and suffocation point(SP) from 0.9 to 1.51 mg·L^-1,when the average weight of W.pigra was 10 g and the water temperature varied from 15 to 35 ℃.OCR ranged from 0.044 to 0.058 mg·g^-1·h^-1,OCV from 0.19 to 0.77 mg·p^-1·h^-1 and SP from 1.4 to 1.57 mg·l^-1 when water temperature was 20 ℃.Conclusion: OCR rose when the water temperature and weight increased,but SP was justly opposite.The weight was negatively correlated with OCR and positively with OCV.OCR had little difference from day to night.
