摘要: 采用流水封闭式装置,测定了不同大小乌苏里拟鲿的耗氧率和窒息点及其24 h的昼夜变化情况。结果表明,大(16.97±1.94 g)、中(1.06±0.06 g)和小规格(0.10±0.01 g)乌苏里拟鲿耗氧率分别为0.160 8、0.191 2和0.275 0 mg/h·g,且各组间差异极显著(P<0.01);窒息点分别为 0.411 4、0.571 9和0.865 2 mg/L,且各组间差异极显著(P<0.01)。所有规格乌苏里拟鲿晚上11:00耗氧率最高,其中大规格和中规格晚上(20:00-8:00)耗氧率持续高于白天(8:00-18:00),且分别在白天和晚上两时段内耗氧率平稳,而小规格乌苏里拟鲿昼夜耗氧率没有明显规律性变化;所有规格乌苏里拟鲿晚上平均耗氧率均高于白天。

Abstract: The oxygen consumption rates and suffocation points of three sizes Pseudobagras ussuriensis were determined using enclosed device with flowing water. The change of oxygen consumption rate in 24 h was also monitored. The results show that the oxygen consumption rate of large(16.97±1.94 g), medium(1.06±0.06 g)and small size(0.10±0.01 g)were 0.160 8, 0.191 2 and 0.275 0 mg/h·g, respectively, the differences among the three sizes were extremely significant(P<0.01)and their asphyxia points were 0.411 4, 0.571 9 and 0.865 2 mg/L, respectively, the differences among the three sizes were also extremely significant (P<0.01). All peaks of oxygen consumption rate of the three sizes appeared at around 11:00 in the evening. The oxygen consumption rates of large and medium sizes during night (20:00-8:00) were higher consistently and stably than that during day(8:00-18:00), but that of small size did not show regular change. The average oxygen consumption rates of the three sizes during night were higher than that during day.

Key words: Pseudobagras ussuriensis, oxygen consumption rate, suffocation point
