Abstract: Bycatch reduction technologies (BRTs) have been developed to limit the incidental capture of non-target marine species in fishing gear, especially those species of special concern. However, in the absence of enforcement, the proven effectiveness of a BRT alone does not guarantee its adoption by fishermen. Human factors also play a fundamental role. This case study was directed at evaluating the willingness of Sicilian longline fishermen to use relatively large circle hooks (size 16/0) as a BRT for the loggerhead sea turtle Caretta caretta. Fishermen were involved in testing circle hooks with their fishing vessels and their own commercial fishing gear, and their opinions before and after trials at sea were recorded. The present study showed the importance of creating a positive human context for testing a BRT. Findings provided additional confirmation about the usefulness of relatively large circle hooks to reduce the bycatch of loggerhead sea turtles on drifting longlines. Interviews before and after trials at sea indicated that socio-economic and emotional factors are essential for successful uptake of BRTs. Crews of large fishing vessels stated that they would be willing to use circle hooks in months with a high probability of turtle captures (June-September) if an economic incentive was provided and there was also public acknowledgement of their efforts. The fishermen's cooperatives association involved in the project is currently evaluating the creation of a product label identifying the harbors where fishing was performed using circle hooks.
