Evaluation of Potential Sustainability of Deep Sea Fisheries for Grenadiers (Macrouridae)

The ability of six grenadier species from the North Atlantic, North Pacific, and Southern Ocean to sustain deep-sea fisheries is assessed. These species are captured in high amounts as bycatch and a few are taken in targeted fisheries, yet population status for most is poorly known or known for only...

Description
Summary:The ability of six grenadier species from the North Atlantic, North Pacific, and Southern Ocean to sustain deep-sea fisheries is assessed. These species are captured in high amounts as bycatch and a few are taken in targeted fisheries, yet population status for most is poorly known or known for only a small portion of their range. A productivity and susceptibility analysis showed that none of the species was highly productive, which was not unexpected given their life history characteristics. While grenadiers were ranked more vulnerable than species in the northeastern Pacific groundfish fisheries, none of the investigated species was ranked as highly susceptible or heavily exploited. This result exposed several weaknesses in the PSA technique and attribute scoring. Management actions and regulations are discussed, which, if employed, might make grenadier fisheries sustainable.
