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....
