The Asphyxiation Point and Oxygen Consumption Rate of Amur Sturgeon, Acipenser schrencki Brandt

摘要

The asphyxiation point(asphyxiation point) and oxy-gen consumption rate(oxygen consumption rate) of Amur sturgeon(10approx60g) were measured. At 20degC, as-phyxiation point decreased from 1.25mg/L to 0.97/L, while the fish body weight increased. As-phyxi otion point is positive interrelated to water temperature, increasing from 0.80mg/L (5degC) to 1.52mg/L (25degC) (body weight 10.09+-0.25).Oxygen comsumption rate is positive interrelated to water temperature and negative interrelated to fish body weight.
