摘  要：
对辽宁、盘锦二界沟镇养殖场池养对虾在6月25日至9月10日间的体长和体重变化进行了同步观测,依据观测结果建立了池养中国对虾体长与体重的回归方程和体长、体重的生长速度方程及加速度方程。结果显示:(1)北方人工养殖的中国对虾其体长与体重的关系式为W=0.02634IL~(2.6327),对虾肥满度大于自然水体增殖,但略差于南方;(2)北方人工养殖的中国对虾其体重生长拐点为48d,比自然增殖的对虾体重生长拐点相比提早7d,比南方池养中国对虾迟后6d;(3)北方人工养殖的中国对虾其体长拐点为20d,比体重拐点提前近一个月,即人工养殖的中国对虾其体长优先于体重生长。体长生长较体重生长提前结束;(4)北方池养的中国对虾极限体重为18.678g,极限体长为12.1cm,与南方池养和自然水域放流的中国对虾的极限体重和极限体长间存在很在并异,放速密度、水温期等是重要的影响因素。以上结果对优化北方中国对虾的池养提供了参考。

摘  要：
Penaeus orientalis cultivated in number 2 Pond of cultivated market in Er Jie- gou village,Panjing city,Liaoning Province was selected as research object.The changes of Penaeus orientalis'length and weight during 25~(th) June-10~(th) Sep were measured at the same time and data were analyzed.The regression equation of length and weight,equations of length growth and acceleration and equations of lweigth growth and acceleration were all established.(?) The results were(1)the relation of Penaeus orientalis'length and weight was W= 0.02634L~(2.6327,)which was heavier than that of naturally cultivated,and lighter than that of pond cultivated in South;(2)the weight growth turning point of pond-culture Penaeus orien- talis in North appeared at the 48 days,which was 7-days earlier than that of naturally cultivat- ed,and 6-days later than that of pond cultivated in South;(3)the length growth turning point of culture Penaeus orientalis in North appeared at the 20 days,which was a month earlier than the weight growth turning point and this meant that length growth was prior than weight growth; (4)the weight limitation of culture Penaeus orientalis in North was 18.678g,and length limita- tion was 12.1cm,both of them differed from Penaeus orientalis pond cultivated in South and naturally cultivated.And these were influenced by density of released Penaeus orientalis,tem- perature.These results provided reference to optimizing Penaeus orientalis pond cultivated in North.
