Mitigation of seabird mortality on factory trawlers: trials of three devices to reduce warp cable strikes

摘要: Experimental trials were conducted onboard a stern trawler to identify the relative efficacy of three emerging mitigation measures (tori lines, warp scarer and Brady baffler) designed reduce seabird mortality caused by cable strikes. The use was clearly shown substantially mortalities from collisions between seabirds cables. Based on an established significant relationship contact rate mortality, when using as index there clear performance hierarchy measures. Tori lines significantly more effective at reducing contacts than Baffler, whilst tori represent smaller, but still significant, improvement scarer. While further testing would be required under local environmental operational conditions, our findings are likely have application for many trawl fisheries around world.
