2018 - 2019 Centre for Environment, Fisheries & Aquaculture Science (Cefas) Small Scale Semi‐Pelagic Trawling Trial in the South West 2018/19 - Fisheries Science Partnership

This work was carried out as part of the Fisheries Science Partnership (FSP) programme. The fishing vessel *Imogen 3* PZ 110 was chartered to undertake the trials in the South West of England otter trawl fishery in August and September 2018. Eleven days of fishing trials were conducted in ICES area VIIE, statistical rectangles 28E3 and 28E4, with a total of 27 hauls completed, 25 of these were considered valid for examination. The specific objective of this trial was to investigate the operation and profitability of a semi‐pelagic trawl towed higher in the water column to catch non‐quota species. It was thought that John Dory ( *Zeus faber* ), Hake ( *Merluccius merluccius* ), Black Seabream ( *Spondyliosoma cantharus* ), Cuttlefish ( *Sepia officinalis* ) and Squid ( *Loligo forbesi * & *Loligo vulgaris* ) could be caught in greater quantities than when using a demersal trawl.本研究作为渔业科学伙伴关系（Fisheries Science Partnership, FSP）项目的一部分开展。2018年8月至9月，包租渔船“伊莫金3号（Imogen 3）”PZ 110，在英格兰西南部的板拖网（otter trawl）渔业区域开展试验。试验在国际海洋考察理事会（ICES）VIIE海区的28E3、28E4统计矩形海域进行，共计完成27次拖网曳航作业，其中25次符合试验检验与分析的有效性要求。本次试验的具体目标为：探究在水层更高位置曳航的半中上层拖网的作业模式与经济效益，以捕捞非配额捕捞物种。研究团队预期，相较于使用底拖网（demersal trawl），该半中上层拖网可捕捞到更多的海鲂（*Zeus faber*）、欧洲无须鳕（*Merluccius merluccius*）、黑海鲷（*Spondyliosoma cantharus*）、普通乌贼（*Sepia officinalis*）以及福氏枪乌贼（*Loligo forbesi*）与普通枪乌贼（*Loligo vulgaris*）。
