Management and enforcement challenges for highly migratory species: the case of Atlantic bluefin tuna.
Atlantic bluefin tuna (ABFT) (Thunnus thynnus) is both an iconic sport fish, with a history of competitive fishing in the Atlantic region (including the largest individual ever caught, in Auld’s Cove, Nova Scotia), and the target of a significant commercial fishery throughout much of its range. The latter is partly driven by the fact that the species is highly valued in the sushi and sashimi markets, but it also has wider markets. The combination of a recreational and large scale industrial fishery is an unusual, if not unique, challenge with respect to the choice of management approaches.
