SUMMARY

SUMMARY

IDENTIFICATION

SCIENTIFIC NAME(s)

Anarhichas lupus

SPECIES NAME(s)

Atlantic wolffish, Seawolf, Atlantic catfish

Some evidence of population structure, based on microsatellite markers, was found within NE Atlantic as well as within NW Atlantic but “homogeneity across the North Atlantic could not be evaluated” (McCusker and Bentzen, 2010). A unique biological stock is identified around Icelandic waters according to both Pampoulie et al. (2012) and Gunnarsson et al. (2013) with an assessment unit considered within (MRI, 2014). But the relation with the remaining distribution of the species in NE Atlantic is not totally understood (McCusker and Bentzen, 2010) nor assessment units are identified apart the Icelandic one.
In lack of a clear stock structure of Atlantic wolffish, assessment units are considered in the NW Atlantic: Scotian Shelf, Georges Bank and Bay of Fundy in Canadian waters (DFO, 2002) were the species has been identified as Special Concern by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC; DFO, 2012) and Gulf of Maine and Georges Bank (Keith and Nitschke, 2010; NOAA, 2015) in US waters where the species was identified as a species of concern in 2004 (NOAA, 2009).

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.

MANAGEMENT QUALITY

As calculated for 2011 data.

The score is < 6.

No management plan is known to be in place for the stock.

As calculated for 2011 data.

The score is 3.4.

This measures the Set TAC as a percentage of the Advised TAC.

The Set TAC is 12.0 ('000 t). The Advised TAC is 8.50 ('000 t) .

The underlying Set TAC/Advised TAC for this index is 141%.

As calculated for 2009 data.

The score is 7.0.

This measures the Catch as a percentage of the Set TAC.

The Catch is 15.5 ('000 t). The Set TAC is 13.0 ('000 t) .

The underlying Catch/Set TAC for this index is 119%.

STOCK HEALTH:

As calculated for 2011 data.

The score is < 6.

No biomass reference points are available but the survey fishable biomass index has been decreasing since 2006 and is below the long-term average. Low recruitment indicates a further decline is expected.

As calculated for 2009 data.

The score is 6.3.

This measures the F as a percentage of the F management target.

The F is 0.356 (age-averaged). The F management target is 0.250 .

The underlying F/F management target for this index is 142%.

DATA NOTES

Notes: No biomass or fishing mortality reference points are known to be set apart from F0.1 which is used by MRI as a basis for advice and has been used here as a proxy for the target fishing mortality. Scores #1 and 4 have been determined qualitatively due to this lack of data.
