为了合理利用渤海对虾的资源,渤、黄海区有关水产研究单位,关于渤海对虾生长规律进行了大量的研究工作,取得了一定的成果。我所自六十年代以来也作了这方面的工作。现仅根据1980和1982年较系统地收集秋虾生长方面的资料分析其生长特性,进而从雌雄秋虾生长特性以及同世代资源状况的关系上来探讨秋虾开捕期的问题。本文所用对虾生物学资料,是取自秋汛滦河口渔场作业的锚网船和机船拖网渔获物。取样的时间自9月5日至11月上旬(即对虾主群泛出该渔场)。每天取样,每次选各中心渔场的对虾1—2份,每份一般是100尾。由于水平所限,错误难免,敬请批评指正。
In order to make rational use of the resources of the shrimp in Bohai Sea, relevant fishery research units in the Bohai and Yellow Sea areas have carried out a great deal of research work on the growth law of the shrimp in the Bohai Sea and achieved certain achievements. I have also done this work since the sixties. The characteristics of autumn shrimp growth were collected based on 1980 and 1982, and the growth characteristics of autumn shrimp were analyzed systematically to explore the problem of autumn shrimp catching period from the growth characteristics of both male and female shrimp and the relationship with the resources of the same generation. Shrimp biological information used in this article, is taken from the autumn Luan estuary fishery operations anchor ship and trawler catches. Sampling time from September 5 to early November (that is, the main group shrimp prawns flooded). Sampling every day, each selected center fishing ground shrimp 1-2 parts, each usually 100. Due to the level of limitations, errors are inevitable, please criticize correction.
