| 摘 要： | 以体质量0.02 g红螯螯虾为研究对象,开展了不同温度(22、25、28、31、34℃)对红螯螯虾虾苗生长影响的试验。试验结果表明随着温度的升高,红螯螯虾虾苗的成活率不断降低,22℃时成活率最高,为48.21%±8.50%,34℃时成活率最低,为21.55%±3.09%,31℃时虾苗特定生长率最高,为7.50%±0.41%。

| Abstract: | The effects of different temperatures(22,25,28,31,34℃)on the growth of C.quadricarinatus(0.02 g)were studied.The experimental results showed that the survival rate of C.quadricarinatus declined with the increase of temperature.The highest survival rate was 48.21%±8.50%when the temperature was 22℃,the lowest survival rate was 21.55%±3.09%at 34℃,and the highest specific growth rate was 7.50%±0.41%at 31℃. |
