| 摘 要： | 本文根据2005年1~11月闽南、台湾浅滩渔场单拖渔业调查监测资料,分析和研究该海区单拖渔业利用状况、主要渔获物资源动态。结果表明:2005年渔获量平均密度指数(CPUE)3月最高,达134.41kg/h,随后迅速下降,9月为全年最低,仅34.75kg/h;渔获物组成以生命周期短、个体小、营养级较低的种类为主,二长棘鲷居绝对优势,占总渔获重量的38.8%;各主要种类渔业资源时空分布变化较为明显;近十年来,渔船功率和网具的日趋大型化,小型单拖渔船数量有所减少。通过监测调查为渔业管理部门制订科学的渔业资源养护措施、加强和完善渔业管理等提供科学依据。

| Abstract: | According to the monitoring data of the single trawler in south Fujian and Taiwan bank fishing ground in 2005,this paper analyzed and studied the utilization status of trawler fishery and the resources of main fishing species in the region.The results showed the CPUE in 2005 is highest in March,over 134.41kg/h,and rapid declining subsequently,and is lowest in September,merely 34.75kg/h.The catch is composed of species of short lifecycle,small individual and low grade of nutrition,Parargyrops edita Tanaka is dominant which occupying 38.8% of the yield.The distribution of main species in time and space is clear in recent years,the power of vessel and net is larger increasingly,the number of small trawler reduced slightly.By monitoring and investigating can provide scientific basis of drawing protective measure for fisheries resources and strengthening fishery management for relative department. |
