【摘要】：根据2016年4~8月在南海北部大陆架渔场广西生产渔船的捕捞信息,通过对比休渔前后的渔获指标,评价了休渔在恢复渔业资源方面的效果。结果表明:(1)单双拖网、桁杆拖虾网和灯光罩网的产量分别占渔船总产量的64.92%、8.70%和24.70%,是该渔场最主要的捕捞类型;(2)休渔后,单双拖网、桁杆拖虾网和灯光罩网渔船的渔获率(CPUE)分别提高了28.78%、96.27%和4.20%,比2015年同期分别提高了24.00%、65.41%和13.35%;(3)单双拖网和桁杆拖网捕获的主要经济种类产量所占比例较休渔前增加了41.74%和3.04%;(4)主要经济种类中,多数种类的CPUE提高,且CPUE提高显著的种类多为经济价值较高的南海传统捕捞对象。研究结论:休渔促使南海北部大陆架渔场的渔业资源量增加,资源结构优化。
[Abstract]:Based on the fishing information of fishing vessels produced in Guangxi, a fishing ground on the northern continental shelf of the South China Sea from April to August 2016, the effect of fishing moratorium on restoring fishery resources was evaluated by comparing the catch indexes before and after the moratorium. The yield of truss shrimp net and lamplight net accounted for 64.922percent and 24.70 percent of the total output of the fishing vessel respectively. It was the most important fishing type in this fishing ground. The catch rate of truss shrimp net and lamplight net increased 28.78%, 96.27% and 4.20% respectively, which was 24.00% 65.41% and 13.35% higher than that of the same period of 2015. The yield of main economic species caught by single and double trawls and truss trawls increased by 41.74% compared with that before the fishing moratorium. Of the main economic categories, The increase of CPUE of most species and the significant increase of CPUE are the traditional fishing objects of high economic value in the South China Sea. The conclusion of the study is that the fishery resources of the continental shelf fisheries in the northern part of the South China Sea are increased and the resource structure is optimized.
