摘　　要：应用密封流水装置测定澳洲银鲈的耗氧率和窒息点。结果表明:在水温24～28℃范围内,平均体长6.7cm的澳洲银鲈鱼苗耗氧率为0.235～0.304 mg/g.h,随水温升高而升高。在26℃时,鱼苗规格大小与耗氧率呈负相关。适温范围内,同一规格鱼苗窒息点随水温升高而升高;同一水温下,窒息点随体长增加而降低。Application of sealing water device for determination of Bidyanus bidyanus oxygen consumption and asphyxiated point.The results show that：at the temperature of 24～28℃,the average body length of 6.7cm.Bidyanus bidyanus fry oxygen consumption of 0.235～0.304 mg/g h,with the water rising.In 26℃,fry specifications size and rate of oxygen consumption was negatively related to.Suitable temperature range,the same specifications fry choke points with water temperature and elevated temperatures;the same,asphyxiated point decreased with body length.
