Bristol Channel Bass Selectivity Survey 2009/10 - Fisheries Science Partnership

This work was part of the Fisheries Science Partnership (FSP), a Defra-funded
collaborative programme of scientific research between the UK fishing industry
and scientists. Local trawlermen working in the Bristol Channel and the South
Wales Sea Fisheries Committee suggested that square-mesh panels fitted into
trawls used to catch bass could reduce discards of undersize bass. A trawl was
modified to incorporate a square-mesh section and was tested on board the MFV
Cerulean against a control trawl.

In August 2009, 46 hauls were conducted. Catches were sampled and video
footage was taken of fish behaviour at the square-mesh section.

本项研究系英国渔业科学合作计划（FSP）的一部分，该计划是由英国环境、食品与乡村事务部（Defra）资助的，旨在促进英国渔业与科学家之间的科学研究合作项目。当地从事布里斯托尔海峡和南威尔士海域捕捞作业的渔民以及南威尔士海域渔业委员会建议，将正方形网眼面板安装于用于捕捞鲈鱼的拖网中，可减少小规格鲈鱼的丢弃。经过改造的拖网被引入正方形网眼部分，并在MFV Cerulean号渔船上与对照拖网进行了测试。2009年8月，共进行了46次拖网作业。对捕获物进行了抽样，并在正方形网眼部分对鱼类行为进行了视频拍摄。
