日本囊对虾(Marsupenaeusjaponicus)体色艳丽，肉质鲜美，是我国重要的养殖虾类。多年来，我国日本囊对虾育苗用的种虾过分依赖海捕资源，用于苗种生产的种虾通常未经选育和检疫，养殖生产苗种的生长较为缓慢、抗病能力差、单产低，这些问题严重制约了日本囊对虾养殖产业的发展。因此，培育生长快速的健康优质虾苗，是关系到日本囊对虾养殖产业可持续发展的重要课题。 论文以课题组选育的日本囊对虾和野生日本囊对虾为材料，通过多元统计方法比较分析了日本囊对虾选育群体和野生群体的形态差异，并采用单因素分析方法探讨了日本囊对虾不同家系的生长特性，研究结果为了解日本囊对虾的选育效果和选育工作的进一步深入开展...Colour of Kuruma shrimp Marsupenaeus japonicus seems gorgeous and its meat is delicious, it has been an important aquatic economic animal since 1980s. However, parent shrimps used for seeding culture are excessively relied on wild resources and are rarely quarantined, besides, the offspring without breeding have problems of slow growth and low yield. All these problems have restricted the develop...学位：理学硕士院系专业：海洋与地球学院_海洋生物学学号：2232012115132
