Challenges in avoiding deep-water shark bycatch in Azorean hook-and-line fisheries

This review summarizes the findings of recent studies from the region, providing an up-to-date science-based framework for mitigating bycatch effects of Azorean hook-and-line fisheries.

Several depth-based, area-based, and gear-based measures have been studied that demonstrate the potential to either avoid or increase the survival of deep-water shark bycatch.

However, these measures may have limited efficacy for some species (e.g. highly mobile species) and thus, limited widespread applicability.

Convincing fishers to avoid deep-water shark bycatch is also a challenge given the antagonistic interactions with sharks damaging the catch and fishing gear, while simultaneously a market incentive for shark liver oil remains

Motivation

Deep-water sharks are highly diverse, vulnerable, and understudied as a group, despite the increasing pressures on their populations.
