摘要
2017年1-12月采集577艘广西海洋捕捞渔船的面上渔情调查数据,计算了各类渔船的带鱼产量比例,在此基础上利用广西主要捕捞类型的产量统计,评估了2017年广西渔船的带鱼产量和产值,并分析其捕捞结构和渔汛期。结果表明:广西渔船的带鱼产量全部来自南海;2017年的带鱼产量为61399吨,产值约6亿元,其中:拖网产量57819吨,灯光罩网3575吨,桁杆拖网3吨,刺网3吨;8-11月的带鱼产量合计占全年产量的74.09%;拖网和灯光罩网的渔获率在9月和12月达到最大,分别为1.56kg/(kW·d)和0.65kg/(kW·d)。文章提出在南海实施带鱼限额捕捞制度,以促进带鱼资源可持续开发。
This paper collected data of random fishery surveys covering 577 Guangxi vessels of various fishing methods from Jan. to Dec., 2017. It calculates ratio of trichiuridae in the total catches from different fishing methods. Based on fishery census on yield of major fishing methods, it estimates yield and output value of trichiuridae of Guangxi fishing vessels in 2017. In addition, it analyzes fishing structure and seasons of the species. It turns out that trichiuridae caught by Guangxi fishing vessels all came from South China Sea (SCS). Guangxi vessels caught 61401 tons of trichiuridae in 2017, involving 57821t from trawling, 3575t from light falling net fishing, 3t from beam trawling, 3t from gill net fishing. Yield of trichiuridae from August to November occupied 74.09% of the total of the year. CPUE topped in September (trawling) and December (light falling net fishing) respectively, measured at 1.56kg/(kW·d) and 0.65kg/(kW·d). Besides, it estimates output value of trichiuridae at 6×10^8 yuan in 2017. This paper calls for implementation of TAC system on trichiuridae in SCS, to promote sustainable exploitation of the resource.
