养殖密度对凡纳滨对虾能量转换效率的影响研究

The effect of density on energy conversion efficiency of juvenile shrimp Litopenaeus vannamei

    摘要
  • 摘要: 为了降低凡纳滨对虾(Litopenaeus vannamei)养殖过程中对环境的污染胁迫,探讨养殖密度与能量转换效率的关系,2004年6~7月在室内水族箱条件下研究了凡纳滨对虾在不同密度下的能量转换效率。试验初始幼虾规格为5.0~6.0 cm, 体重2.75~3.20g尾-1。实验设3个密度梯度组,分别为50、150和400尾m-3,实验水体010m3,投饵率4%~7%,养殖时间3周。结果表明,试验密度为50尾m-3时,能量转换效率为19.31%1.01%;150尾m-3时为22.56%2.69%; 400尾m-3时为15.31%2.49%。显然,养殖密度对凡纳滨对虾能量转换效率产生明显影响,3组密度试验显示,以150尾m-3密度组能量转换效率最高。

     

    Abstract: A study was undertaken to evaluate the effect of the densities on the energy conversion efficiency of Litopenaeus vannamei in June~July, 2004. The experimental juvenile shrimps of 5.0 to 6.0 cm per individual and 2.75 to 3.20 g per individual were reared in 9 tanks (0.10 m3) for three weeks with three different densities, 50, 150 and 400 indm-3, respectively. Each treatment was triplicate. The feed ratio was 4% to 7%. The results showed that the energy conversion efficiency were 19.31%1.01%, 22.56%2.69% and 15.31%2.49% in 50 indm-3 group, 150 indm-3 group and in 400 indm-3 group, respectively. The highest energy conversion efficiency was observed in shrimp reared in 150 indm-3 group. It indicated that the energy conversion efficiency was significantly affected by density.
