Sustainable alternatives:
Pacific Cod caught by trap or bottom longline is a sustainable seafood option.
Sustainability concerns:
Bluenose are a long-lived species with low resilience to fishing pressure. Relatively little is known about the biology and abundance of this species.
Bluenose marketed in North America are mainly caught in New Zealand. Poor management has resulted in population declines, bycatch concerns are not actively addressed, and habitat damage is a concern.
Life History and Population Status:
Bluenose are a long-lived deepwater fish. Information on this species has been sparsely collected since the 1980s, but much of its biology and population status are unknown.
Management:
Management measures include annual quotas and methods to reduce bycatch. In New Zealand and Australia, there are currently no stock assessment programs in place.
Impact on Other Species:
The bluenose hook and line fisheries are known to inadvertently capture groupers, grenadiers, seabirds and dogfish (sharks). Management plans have provisions to reduce bycatch in the future but currently this is still a concern. Bycatch from bottom trawling remains a large concern.
Habitat and Ecosystem Impacts:
Deepwater trawls damage seabed habitats including sensitive coral reefs and communities. Since the bluenose fishery is primarily hook and line, this is not a major concern.
Notes:
- No or little concern in this area.
- Significant concern in this area.
- Area under study.
