The Southern Ocean Toothfish Fishery – conflicting evidence highlights uncertainty in fishery management.
The Southern Ocean toothfish fisheries, -managed by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR)- are constantly examined for their sustainability and greater ecosystem impacts. Despite fish biology and ecosystem interactions having been investigated since the es...
