北方高位池养殖凡纳滨对虾的生长特性

The growth of Litopenaeus vannamei in higher-place ponds in northern China

为了解北方高位池养殖凡纳滨对虾(Litopenaeus vannamei)的生长特性,对其体质量和体长进行了测定,并使用von Bertallffy方程进行了体长和时间的生长曲线的拟合,对体长和体质量的关系进行了相应的分析。结果表明,体长和体质量的关系为:W=1.275×10^(-8)L^(4.40),von Bertalanffy方程:L_(t)=165.19(1-e^(-0.0139(t+17.7852)))。通过分析凡纳滨对虾的生长规律,为适时出塘提供策略。

To understand the growth characteristics of the whiteleg shrimp Litopenaeus vannamei raised in higher-place ponds in northern China,body weight and standard length of the shrimp were measured.The growth curve of Litopenaeus vannamei for standard length and time was fitted using the von Bertallffy equation.The length-weight relationship was also analysed.The results showed that the length-weight relationship was:W=1.275×10^(-8)L_(4).40,and the von Bertalanffy equationwas:L t=165.19(1-^(e-0.0139(t+17.7852))).By analyzing the growth pattern of Penaeus vannamei,a strategy for timely sales was provided.
