摘　　要：对高位池精养日本囊对虾Marsupenaeus japonicus的体长和体质量进行跟踪测量,研究其生长特性及其规律。结果表明：日本囊对虾的体长和体质量呈幂函数关系,即W=1.182×10-5L3.0235,b接近于3,呈等速生长。其生长分为快速生长期（30~60日龄）、稳定生长期（60~90日龄）和缓慢生长期（90~130日龄）3个时期。生长早、中期（50~90日龄）肥满度逐渐升高（1.14~1.23）,趋势显著,之后呈显著下降趋势（1.19~1.14）。拟合出日本囊对虾的von Bertallanffy生长方程为：Lt=111.796×[1-e-0.0123（t＋0.07654）],Wt=15.611×[1-e-0.0123（t＋0.07654）]3.0235,体质量生长拐点出现在89.9 d。The growth characteristics were studied on the basis of the successive data of body length and body weight of kuruma shrimp Marsupenaeus japonicus cultured in intensive ponds above sea level. The results showed that the relationship between body length and body weight was described by the power function： W = 1. 182×10^-5 L^-3.0235, where the value b was close to 3, indicating an isometric growth. The shrimp growth was showed to be divided into three stages： fast growth stage in the 30-60 day old shrimp, steady growth stage in the 60-90 day old shrimp and slow growth stage in the 90 day old shrimp and later. The condition factor （1.14-1.23） was gradually increased in a significant trend at early and middle growth stage, and later in a gradually decreased trend（ 1.19- 1.14）. The von Bertallanffy equations were expressed as the follows： Lt = 111. 796 [ 1 -e^-0.0123 （t＋0.07654） ], Wt = 15.611 [ 1-e^-0.0123（t＋0.07654）]^3.0235. The inflection of body weight growth was found in about 89.9 days.
