摘要
在突验室内，对中华鳖幼体的能量转换进行了初步研究。结果表明：１）温度结中华鳖幼体对食物的同化效率无显著影响，但影响总转化效率和生长效率。二者在２２℃左右最高，２６—３２℃温度范围内各温度组之间元显著差异，３５℃则显著下降。２）体重与同化效率的关系为：ＡＥ＝９４．１８６＋２．７６０ｌｇＷ，而生长效率和总转化效率在各体重组间无显著变化；３）中华鳖幼体能量收支方程为：１００Ａ＝７４Ｒ＋２６Ｇ，并认力中华鳖将较多能量（７４％）投入代谢，而将较少能量（２６％）投入生长是适应其生态习性的缘故。
Eenergy conversion in the juvenile soft-shelled turtle Trionyx sinensis was preliminary studied in the laboratory. The results show as follow: 1. No significant difference in theassimilation efficiency was observed at various temperatures.The gross conversion efficiencyand production efficiency at temperature of 22℃ were strikingly higher than at other levels oftemperature. But at the other temperature levels,both the gross conversion efficiency and production efficiency were not significantly different. 2. The correlation between assimilation efficiency and body weight could be expressed by AE=94. 186 +2. 760 lgW. But there was nosignificant differences in gross conversion efficiency and in production efficiency among thegroups of body weight. 3. From the results, we obtained the formula of energy flow: 100 A=74 R+26 G. In conclussion, it is an adaptation to its ecological characteristics that T. sinensis channelled more energy (74%) to metabolism to raise its survivorship while less energy(26 % ) to growth to shorten breed interval time and enhance fecundity.
