To study the oxygen consumption rate and suffocation point of Whitmania pigra.
Using the method of respiratory chamber, the oxygen consumption rate, oxygen consumption volume and suffocation point were obtained.
The oxygen consumption rate(OCR) ranged from 0.049 to 0.094 mg x g(-1) x h(-1), the oxygen consumption volume(OCV) from 0.44 to 0.67 mg x p(-1) x h(-1), and suffocation point(SP) from 0.9 to 1.51 mg x L(-1), when the average weight of W. pigra was 10 g and the water temperature varied from 15 to 35 degrees C. OCR ranged from 0.044 to 0.058 mg x g(-1) x h(-1), OCV from 0.19 to 0.77 mg x p(-1) x h(-1) and SP from 1.4 to 1.57 mg x l(-1) when water temperature was 20 degrees C.
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.
研究宽体金线蛭的耗氧率和窒息点。
采用呼吸室法，测定宽体金线蛭的耗氧率、耗氧量和窒息点。
当宽体金线蛭平均体重为10g，水温在15至35℃之间变化时，耗氧率（OCR）范围为0.049至0.094mg·g⁻¹·h⁻¹，耗氧量（OCV）为0.44至0.67mg·p⁻¹·h⁻¹，窒息点（SP）为0.9至1.51mg·L⁻¹。水温为20℃时，耗氧率范围为0.044至0.058mg·g⁻¹·h⁻¹，耗氧量为0.19至0.77mg·p⁻¹·h⁻¹，窒息点为1.4至1.57mg·L⁻¹。
耗氧率随水温及体重的增加而升高，但窒息点则相反。体重与耗氧率呈负相关，与耗氧量呈正相关。耗氧率昼夜差异不大。
