| 中文摘要: |
| 为评估中华鳖（Pelodiscus sinensis）黄河群体、洞庭群体及其杂交选育群体绿卡鳖（洞庭♀×黄河♂的杂交子代经过5代群体选育所得）的生长性能，对露天池塘养殖条件下3个选育群体进行了连续观测对比试验遥试验时间为2012年8月1日到2014年4 月15日。除越冬期外，每30d左右记录3个群体的生长数据。结果显示：（1）在生长速度方面，表现为黄河鳖跃绿卡鳖跃洞庭鳖：（2）在整齐度方面，稚鳖期绿卡鳖的整齐度最好，幼鳖期表现为洞庭鳖＞绿卡鳖＞黄河鳖：（3）三者的裙边比无明显差异：（4）饲料利用率表现为洞庭鳖＞绿卡鳖＞黄河鳖，存活率表现为洞庭鳖＞绿卡鳖＞黄河鳖。综合可见绿卡鳖具有明显的优势，应予以推广。 |
| 英文摘要: |
| In order to assess growth performance of Pelodiscus sinensis in three populations including Huanghe (HH),Dongting (DT), Luka (LK, DT♀×HH♂ ), a continuous observation comparison test was carried out in outdoor pond aquaculture system. The experiment started from August 1, 2012, ended at April 15, 2014. Growth data of three populationsof P sinensis were recorded every 30 days except winter. Results showed that: (1) The order of growth rate was DT＞L＞KHH; (2) The best uniformity was Luka population in early stage, the order during young stage was DT>LK>HH; (3) There was no obvious difference in the back apron width of three populations; (4) The order of feed utilization was DT＞LK＞HH,survival rate was DT>LK>HH. LuKa was better than Huanghe while inferior to Dongting at growth speed, uniformity andaverage daily yield per 1 m2. Totally, Luka has obvious advantages and should be promoted. |
