脊尾白虾对蛋白质和脂肪需求量研究

Study on the Requirements of Protein and Lipid for Exopalaemon carinicauda

研究了不同饲料粗蛋白水平(52.59%,45.67%,38.91%,32.39%,26.60%)和粗脂肪水平(3.07%,5.03%,8.02%,10.96%,13.95%)对脊尾白虾生长的影响,实验周期为30 d。结果表明,脊尾白虾特定生长率在饲料粗蛋白45.05%、粗脂肪8.67%达到最大值,且随着饲料粗蛋白和粗脂肪水平继续增加,脊尾白虾特定生长率呈下降趋势。

Experiment is made to determine the effect of different crude protein levels （52.59%, 45.67%, 38.91%, 32.39%, 26.60%） and crude lipid levels （3.07%, 5.03%, 8.02%, 10.96%, 13.95%） on the growth of Exopalaemon carinicauda. It lasts for 30 days. Results show that the specific growth rate of Ezcopalaeznon carinicauda was the highest with the crude protein level of 45.05% and the crude lipid level of 8.67%, but the growth rate showed a decline with the increase of protein and lipid levels.
