根据2000~2002年对福建沿海地区流刺网渔业的专题调查研究资料,着重研究了福建海区流刺网渔业的作业型式、渔具规格、数量分布、存在问题、发展趋势及管理对策。结果表明,福建海区流刺网渔业的渔船数量位居各种海洋捕捞作业的首位,渔具型式和规格多种多样;依作业海域划分,沿岸水域流刺网渔船数量最多,其次为近海水域,外海水域居第三,分别占75·6%、18·5%和5·9%;按作业型式划分,单片式流刺网的渔具数量最多、三重流刺网次之、双重流刺网最少,分别占65·0%、25·0%和10·0%。调查研究结果还表明,流刺网渔具普遍存在网目规格日趋小型化现象,这与近海捕捞种类呈现小型化趋势相一致,且二者有密切的因果关系;大多数的渔获种类均可达到初次性成熟体长,说明目前流刺网渔业对渔业资源的利用较为合理。展望流刺网渔业发展前景,提出相应管理对策。
According to the survey data of strewing nets fishery in Fujian coastal area from 2000 to 2002, this paper focuses on the operation types, fishing gear specifications, quantity distribution, existing problems, development trend and management countermeasures of streptococci in Fujian sea area. The results show that the number of fishing vessels in Fujian sea area is the highest among all kinds of marine fishing operations, and the types and specifications of fishing gear are varied. According to the classification of operating waters, the number of fishing nets is the highest in coastal waters, followed by the offshore waters and the offshore The waters occupied the third place, accounting for 75.6%, 18.5% and 5.9% respectively. According to the types of operations, the single-piece spill-punching network had the largest number of fishing gear, followed by the triple-spunlace network and the least double-spunlace network Accounting for 65.0%, 25.0% and 10.0% respectively. The findings of the survey also showed that there is widespread miniaturization of mesh specifications for streamers, which is consistent with the tendency of miniaturization of offshore fishing species, and the two are closely causal; most of the catches can be reached The first time mature body length, indicating that the current spiny net fishing fisheries resources utilization is more reasonable. Looking forward to the development prospects of streamers fisheries, put forward corresponding management measures.
