摘要
根据20世纪80年代初至90年代初浙江渔场拖虾调查及近几年东海区虾类资源动态监测调查资料,测定戴氏赤虾2670尾,其中雌虾1389尾,雄虾1281尾。对其群体的体长、体重组成,体长与体重的关系,繁殖与生长等生物学特征进行分析,为合理利用和渔业管理提供科学依据。
According to the investigations on shrimp trawling in the fishing ground of Zhejiang from the beginning of 1980′ s to the beginning of 1990′ s and the information of dynamic monitoring on shrimp stock in the recent years, and by measuring 2 670 samples of Metapenaeopsis dalei (1 389 samples is♀ ,1 281 samples is♂ ),the biological characteristics are analysed of the group of body length, weight of groups,the relationship between body length and weight, and the characteristics of sex,propagation and growth,which offered the theorietical evidences for rational exploitation in the future.
