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.
