| 摘 要： | 在水温19—28℃下，测定了匙吻鲟Polyodon spathula（14．98g±1．35g～156．42g±23．46g）的耗氧率和窒息点。结果表明：匙吻鲟幼鱼耗氧率有昼夜节律性，一昼夜出现两个高峰值，分别在8：00和18：00，低峰值出现在0：00。耗氧率（Y）与水温（T）呈显著正相关，Y=0．2918T^0.2818（R^2=0．9477）；耗氧率（Y）与鱼体重（W）呈显著负相关，Y=0．2924W^-0.1663（R^=0．9326）；耗氧量（Y＇）则与体重呈显著正相关，Y＇=4．675W^1.5136（R^2=0．9332）；匙吻鲟的窒息点为（2．813±0．056）-（3．468±0．072）mg／L（以O2计）。

| Abstract: | The standard oxygen consumption rate and asphyxial point of juvenile（ 14.98 g ± 1.35 g - 156.42 g ±23.46 g） paddlefish （Polyodon spathula）were measured at 19 -28 ℃. The diurnal rhythm of the standard oxygen consumption was observed in the paddlefish, with the peak at 8：00 and 18：00, and the minimum at 0：00. The correlation between standard oxygen consumption rate（Y） and water temperature （T）was represented by the equation Y = 0. 2918T^0. 2818, and the standard oxygen consumption rate（Y） decreased with the body weight（W） increasing while the standard oxygen consumption （Y＇） increased with the body weight increasing, the correlation formulas were expressed as Y =0. 2924W^-0.1663 and Y＇ =4. 675W^1.5136 The asphyxial point was found to be （2. 813 ± 0. 056） - （3. 468 ± 0.072） mg/L. |
