摘　　要：对与中华乌塘鳢（Bostrychus sinensis）混养模式下的日本囊对虾（Marsupenaeus japonicus）选育新品系的体长、体质量等生长特性进行了100d的跟踪测量分析,结果表明：经过100d的养殖,虾鱼混养模式下日本囊对虾选育新品系平均体长和体质量分别由8mm和0.006g增加至112.73mm和18.35g,其生长分为快速生长期（30~50日龄）、稳定生长期（50~70日龄）和缓慢生长期（70日龄以后）,在30~50日龄间,体长的生长速度较快,随着日龄的增加,体长生长速度变缓,体质量的生长拐点出现在55d左右;体质量和体长呈幂函数关系,关系式为W=1.0×10-5 L3.053,L的指数接近3,呈等速生长;混养模式下日本囊对虾选育新品系体长和体质量的von Bertallanffy生长方程为：L=127.45×（1-e-0.024t＋0.212）,W=26.77×（1-e-0.024t＋0.212）3.053.研究结果为探索日本囊对虾适宜的养殖模式和选育新品系的选育效果提供了基础资料.The growth characteristics of bred Marsupenaeus japonicus in M.japonicus-Bostrychus sinensis polyculture ponds were studied according to the measurement of body length and body weight.Results showed that the average body length and body weight of bred M.japonicus were 112.73 mm and 18.35 g for 100-day cultivation respectively.The growth period of shrimps was devided into three stages：fast growth stage（30-50days）,steady growth stage（50-70days）,and aging growth stage（after 70days）.The body length increased fast in 30-50 days,then slowed down gradually with age.The inflection of body weight growth was found in about 55days;the relationship between body length and body weight was described by apower function：W =1.0×10-5 L3.053,where the index of Lwas close to 3,indicating an isometric growth.The von Bertallanffy equations were expressed as follows：L=127.45×（1-e-0.024t＋0.212）,W =26.77×（1-e-0.024t＋0.212）3.053.In sum,this study provides fundamental information to help explore appropriate aquaculture mode and bred effect of M.japonicus.
