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。
The growth and contrast experiments were conducted on the wild shrimp cultivated in the Taihu Lake and Changxing aquaculture shrimp as parent breeds (respectively recorded as the wild group and the cultured group). After 90 days of breeding, the wild group was 46 70 cm long and the farmed group was 37 60 cm. The absolute daily gain was 4 638% in the wild and 3883% in the farmed herd. The survival rate was 98 6 ± 2 4% in the wild and 94 9 ± 1 6% (41 3 ± 2 3)%, and the cultured population was (62 8 ± 2 8)%. Wild shrimp breeding shrimp in body length, body weight, survival rate and sexual maturity and other growth performance are better than breeding shrimp breeding shrimp.
