摘　　要：报道了史氏鲟和杂交鲟鱼种的耗氧量、耗氧率和窒息点。耗氧量随着体重的增加而增加 ,但耗氧率却随着体重的增加而减少。在 1 4～ 3 0℃的水温范围内 ,耗氧率随着水温的上升而增加 ,并呈正相关关系。史氏鲟和杂交鲟的窒息点分别是 1 .2 8～ 1 .3 7mg /L和 1 .3 6～ 1 .44mg /L。The oxygen consumption and asphyxiating point of fingerlings of Acipenser schrencki and Huso dauricus ×A.schrencki were reported.The oxygen consumption increased gradually while the oxygen consumption rate decreased gradually with the increase in body weight. The oxygen consumption rate increased with the increase in water temperature within the range of 14～30℃, and there was a positive correlation .Their asphyxiating point were 1.28～1.37 mg/L(A. schrencki) and 1.36～1.44 mg/L(Huso dauricus×A. schrencki).
