Summary
Three seabird bycatch mitigation measures, tori lines, warp scarer, and Brady baffler, were tested on trawlers and compared with a control treatment of no mitigation measure. Each mitigation measure reduced seabird mortalities; however, the tori lines, followed by the warp scarer, were much more effective at reducing seabird contact with fishing gear than the Brady baffler.

Effect on bycatch species
Tori lines and the warp scarer were significantly more effective at reducing contacts than the Brady Baffler, whilst tori lines represent a smaller, but still significant, improvement on the warp scarer
