【摘要】 测定了饥饿状态下中华鳖（Ｔｒｉｏｎｙｘｓｉｎｅｎｓｉｓ）幼鳖在水中的呼吸代谢及其与温度、体重的关系。体重１６～１５０ｇ的幼鳖在水温２８℃下的个体耗氧率Ｒ可表示为：ｌｇ（Ｒ／ｍＬ·ｈ－１）＝０．６３１４ｌｇ（Ｗ／ｇ）－１．０５４９（Ｗ为个体湿重）；ｒ＝０．９１，ｎ＝２６，Ｐ＜０．００１，这时幼鳖的单位体重耗氧率Ｖ与体重呈如下负相关关系：Ｖ＝８８．１２５４Ｗ－０．３６８６；ｒ＝０．８０，ｎ＝２６，Ｐ＜０．００１．中华鳖能够正常活动、摄食的温度范围为２０～３５℃。２０，２４，２６，２８，３０，３２，３５℃下３０～６０ｇ幼鳖水中呼吸耗氧率的变动范围为２４．３７～３１．２０ｍＬ·ｋ－１·ｈ－１．ｔ检验表明温度对鳖在水中的呼吸没有显著影响．更多还原

【Abstract】 Aquatic respiration by starved juvenile soft-shelled turtle,Trionyx sisnesis,relative to body weight and water temperature was measured.The relation of oxygen consumption rate to body weight for 16～150g turtle at 28℃ was described by the equation:lg(R/mL.h-1)=0.6314 lg(W/g)-1.0549;r=0.91,n=26,P<0.001,and relation of weight-specific oxygen consumption to body weight was V=88.1254 W-0.368 6;r=0.80,n=26,P<0.001.The temperature range in which the turtle can normally feeding and growing is 20～35℃.Weightspecific oxygen consumption for 30～60g individuals at 20,24,26,28,30,32,35℃ showed no distinct differences by t-test(P>0.05),and the values varied at 24.37～31.20 mL.h-1.kg-1.更多还原
