| 摘 要： | 较系统研究了斑节对虾、墨吉对虾、日本对虾和刀额新对虾等４种对虾的耗氧率、ＣＯ２排出量、呼吸商和窒息点。结果表明，同一种类不同大小和不同种类及生活习性不同，耗氧率、ＣＯ２排出量、呼吸商和窒息点有较大的差别。日本对虾、刀额新对虾的耗氧率、ＣＯ２排出量比其他两种虾低。墨吉对虾次之，斑节对虾为最高。对ＤＯ忍受能力，刀额新对虾最强，在ＤＯ０．６０ｍｇ／Ｌ才开始出现窒息。斑节对虾次之，在ＤＯ降至０．８８ｍｇ／Ｌ出现窒息。墨吉对虾在ＤＯ１．１９ｍｇ／Ｌ出现窒息。日本对虾忍受ＤＯ能力最差，在以ＤＯ１．３１ｍｇ／Ｌ出现窒息。

| Abstract: | The oxygen consumption rate,CO2 exhaust, respiratory quotient, and asphyxiation point inPenaeus monodon, P. merguiensis, P. japonicus and Metapenaeus ensis, are studied systematically inthis article. The results indicate that different species have great differences in their living habits. M.ensis has a lower oxygen consumption rate and asphyxiation point than the other three species. Withinthe same species, the oxygen consumption rate decreasing when their body weight increases. Juvenileshrimps require higher oxygen consumption rates. Also, oxygen consumption is closely related to thewater temperature. Within the same species, the stronger shrimps have greater abilities to withstandlower DO and weak shrimps are unable to withstand lower DO. |
