Abstract
The incidental capture and mortality of endangered, threatened and protected (ETP) marine species remains a global problem. Among the most problematic fishing methods is penaeid trawling, which is responsible for one quarter of the world's discarded bycatch and remains a key threatening process to ETP species (turtles and some elasmobranchs). So-called ‘turtle excluder devices’ (TEDs) legislated among USA penaeid trawlers and subsequently fleets in other countries during the 1990s alleviated some concerns over impacts to ETP species, but adoption has not been global. One country characterised by resistance to TEDs is Brazil—despite federal legislation mandating usage for almost 25 years. The reasons for this deficit, reiterated here via interviews with 64 southern penaeid-trawler captains, are threefold. First, are perceived issues with mandated designs and minimal third-party expertise, leading to a sustained misconception that TEDs simply do not work in Brazilian penaeid trawls. Second, is the perpetuated belief of minimum negative impacts to ETP species; exacerbated by few quantitative data. Third, is jurisdictional failure to promote the concept that slight economic loss associated with not catching ETP species (elasmobranchs) is necessary for broader ecological sustainability. We propose TED use among Brazilian penaeid-trawl fisheries might be promoted via a co-management strategy facilitated by sustained education and technical expertise from research providers encouraging fishers to develop fishery-specific solutions. If industries can be encouraged to accept the concept of TEDs, they might then be expected to refine and develop ownership of the most appropriate configurations.
