The oxygen consumption rate and asphyxiaton point of Leptobotia elongata (Bleaker)are studied by Krogh's method The oxygen consumption rate(Y')of the fish decreases with the body weight increasing, while oxygen Consumption(Y)increases with the body weight(W')in-creasing under water temperature 22-23℃.The regretion line may be represented by the fol-lowing equations respectively:Y'=186.576W^－0.2043 and Y'=0.186W^0.7962.The water ternpera-ture affects rate of oxygen cons umption in Leptobotia etongata, it increases gradually with water temperature rising at 13-3O℃.Changes of oxygen consumption rate are bigger at the ranges of low temperature(13-23℃)and high temperature(28-30℃), but amount of increase in oxy-gen consumption rate and metabolism is relatively lower under water temperature 23-28℃.Daily fluctuation of the oxygen consumption rate was also observed in the experiment The oxygen consum ption rate Was the highest at 2:00.a.m., the lowest at 4:00.P.m.Asphyxiation point of the fish is 0.94-1 06mg/L when the body weight of the fish is 38-59g.0.62-0.70rag/L when body weight is 250-320g.
