SUMMARY

SUMMARY

IDENTIFICATION

SCIENTIFIC NAME(s)

Cancer magister

SPECIES NAME(s)

Dungeness crab

COMMON NAMES

Dungies, Market crab

The stock structure of Dungeness crab (Cancer magister) on the Pacific coast of North America is not clear, with studies from Oregon showing no evidence of sub-structuring (O’Malley K, and Roegner C 2013) but studies from British Columbia showed differentiation of several populations (Beacham TD and Supernault J 2008). Further genetic studies with a broader scope are currently underway.

Despite some evidence for sub-populations, it is not clear if the assessment of Dungeness crab in British Columbia is aligned with these units, and stock assessment surveys are conducted by management areas (Fisheries and Oceans Canada 2015).

1. This profile is not currently at the top of our priority list for update/development, and we can’t at this time provide an accurate prediction of when it will be developed. To speed up an evaluation of the sustainability status of non-prioritized fisheries we have initiated a program whereby industry can directly contract SFP-approved analysts to develop a FishSource profile on a fishery.

Fisheries

Within FishSource, the term "fishery" is used to indicate each unique combination of a flag country with a fishing gear, operating within a particular management unit, upon a resource. That resource may have a known biological stock structure and/or may be assessed at another level for practical or jurisdictional reasons. A fishery is the finest scale of resolution captured in FishSource profiles, as it is generally the scale at which sustainability can most fairly and practically be evaluated.

The score is ≥ 6.

Biomass recognized to be stable given lack of formal assessment

As calculated for 2012 data.

The score is ≥ 6.

Fishing mortality is recognized to be stable and sustainable in the long term, but uncertainty exists due to a lack of formal assessment in the near term.
