2016年广西海洋捕捞产量结构研究

Study on structure of catches of marine fishing of Guangxi in 2016

研究单位在广西沿岸渔港布设捕捞信息采集点,2016年1-12月采集了563艘(对)渔船在南海的捕捞面上信息。本研究以信息渔船的产量统计为基础,分析广西海洋捕捞的作业类型及其渔场结构,进一步研究拖网的渔获结构和渔获率的时空变化。结果表明:(1)拖网和灯光罩网的产量分别占总产量的72.01%和26.89%;(2)各渔区的产量占比为:北部湾渔区占41.93%,南海北部大陆架渔区占34.17%,北部湾湾口外渔区占3.02%,南海外海渔区占20.88%;(3)拖网的主要渔获种类有16种,其合计产量占拖网总渔获量的57.76%;(4)2016年南海各渔区拖网的渔获率比2015年全面上升。研究结果可为改善南海渔业生产管理、促进南海渔业资源修复和养护提供参考和依据。

We designed investigation stations in fishery ports along Guangxi coast, and collected general fishing information from 563 fishing boats distributed in South China Sea（SCS） from Jan. to Dec., 2016. Based on statistics upon catches from the boats mentioned, this paper analyses structure of fishing methods and of distribution of Guangxi boats in SCS. Besides, it analyses dominant species and the proportion in catches, and variation of CPUE of trawling. Studies turn out：（1） Ratio of catches from trawling and light-falling to the totals counts at 72.01% and 26.89% respectively.（2） Proportion of catches of various grounds to the whole SCS list as： Beibu Gulf,41.93%; continental shelf of northern SCS, 34.17%; mouth of Beibu Gulf, 3.02%; offshore of SCS, 20.88%.（3） Dominant species of trawling include 16 ones, accounting for 57.76% of the totals in weigh.（4） CPUE of trawling in various sections of SCS increase in a full scale in 2016 compared to 2015. Data and conclusions are suggested as references for improvement to fishery management, and promotion of recovery maintenance of fishery resource of SCS.
