摘  要：
2012年4-8月对环黄渤海三省一市沿海一线的拖网渔具情况进行了调查分析,主要调查了拖网渔具的作业型式、渔场、渔获物组成、渔具结构、渔船数量及分布等现状。结果表明:黄渤海区三省一市在册拖网渔船12 358艘,其中110.3kW(150马力)以下渔船约占70%,而110.3kW以上渔船只占30%,拖网渔船数量随渔船功率增大而减少。网具结构主要包括以下几种型式:单船桁杆型拖网、双船有翼单囊浮拖网、单船有翼单囊底拖网。黄渤海区拖网总船数量巨大,严重破坏近海渔业资源,渔具选择性差,渔具标准缺失较多,科研滞后。

摘  要：
Situation of trawl gears and fishing methods have been investigated and analyzed in the terms of types of trawl fishing operations,fishing grounds,composition of the catch,structure of trawl gears,numbers and distribution of fishing vessels etc,along the coast of Yellow Sea and Bohai Sea area during June-July,2012.The results showed that:All types 12 358 trawlers were found in surroundings of the Yellow Sea and Bohai Sea area,which only 30% of fishing vessels' power is more than 110.3kW,the number of fishing vessels reduced as the fishing vessels power increases.Mainly includes the following structure of trawl gears:the single-vessel beam trawl,double-vessels floating-trawl with double-wings and single-cod-end,the small single-vessel ground-trawl with double-wings and single-cod-end.It's a huge number of trawl vessels working in the Yellow Sea and Bohai Sea area,taking serious damage to coastal fisheries resources,and the selectivity of fishing gears is inefficient.The fishing equipment needs standardization and calls for scientific research.
