| 摘 要： | 以太湖野生青虾和长兴养殖青虾为亲体繁殖的虾苗(分别记作了野生群和养殖群)进行生长对比试验,经90d饲养,野生群体长为46 70cm,养殖群为37 60cm;体重日绝对增重率野生群为4 638%,养殖群为3 839%;成活率野生群为(98 6±2 4)%,养殖群为(94 9±1 6)%;抱卵率野生群为(41 3±2 3)%,养殖群为(62 8±2 8)%。野生青虾繁殖的虾苗在体长、体重、成活率和性成熟等生长性能均优于养殖青虾繁殖的虾苗。

| Abstract: | Two populations of shrimp Macrobrachium nipponense, cultured population from Changxing Country, Zhejiang Province and wild population from Taihu Lake, were cultured in net cages to compare their growth performance, including length gain, weight gain, survive rate, and sex maturation etc. The results showed that there was better growth performance in the wild population from Taihu Lake than that in the cultured population from Changxing Country, Zhejiang Province. |
