| 摘 要： | 为了测试选育中华绒螯蟹‘长江一号’的生长性能,于2009-2010年通过在相同养殖环境、相同饲养管理、相同养殖密度的条件下,采用现实生产中先进的中华绒螯蟹生态养殖技术主导模式,进行‘长江一号’中华绒螯蟹生产性对比养殖试验。结果表明,1龄蟹种培育的平均规格、存活率,选育系与对照系无显著差异;性早熟比例,选育系分比对照系降低5%;2龄成蟹养殖,‘长江一号’选育系比对照系生长快,平均体重增长快21.64%,呈极其显著差异（P<0.01）,单产平均提高21.22%。选育系的平均日增重率比对照组提高了22.73%,平均体重变异系数比对照组降低19.14%。连续2周年的生产性对比试验结果表明,中华绒螯蟹‘长江一号’生长快、群体规格整齐、养殖存活率高、增产效果明显,深受广大养殖户的欢迎,市场应用和产业化前景广阔。

Comparison on Growth Performance of Crab (Eriocheir sinensis) Strain of ‘Chang Jiang 1’ |
| |
| Abstract: | Several experiments had been conducted to study the growing performance between the new strain of Erocheir sinensis named ‘Chang Jiang 1’ and common crab under the conditions of same culture environment, same feeding management, same stocking density. The results showed that the average size and the survival rate were not significant difference between ‘Chang Jiang 1’ and common crab at age 1, the proportion of precocious puberty of ‘Chang Jiang 1’ than common crab was reduced by 5%. The growth was faster for ‘Chang Jiang 1’ than that for common crab at age 2. The average weight increased by 21.64% and there was extremely significant difference (P<0.01), yield an average improvement of 21.22%. The daily growth rate of F5 was improved 22.73% over that of control line and the variation coefficient of body weight was reduced 19.14%. Continuous production of the second anniversary of the comparative test results showed that the ‘Chang Jiang 1’ grew fast, neat group size, breeding survival rate was high, increased yield, welcomed by the majority of farmers, markets and industrial applications prospects.The growth was faster for “Chang Jiang 1 ” than that for common crab at age 2.The average weight increased by 21.64% and there was extremely significant difference ( P < 0.01 ), yield an average improvement of 21.22%. The daily growth rate of F5 was improved 22．73％ over that of control line and the variation coefficient of body weight was reduced 19.14％ ．Continuous production of the second anniversary of the comparative test results show that the " Chang Jiang 1 " grow fast, neat group size, breeding survival rate is high, increase yield, welcomed by the majority of farmers, markets and industrial applications prospects. |
