IDENTIFICATION

SCIENTIFIC NAME

Hippoglossus hippoglossus

SPECIES NAME(S)

Atlantic halibut

COMMON NAMES

Halibut in 3NOPs4VWX5Zc

Atlantic halibut move extensively throughout Canada’s Atlantic waters (DFO, 2015) and are thus managed and assessed on this broad scale. Studies have shown migrations into US waters and there could also be exchanges with Icelandic waters (NMFS, 2009) but there is also evidence for separation of stocks (Shackell et al, 2015).

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.

1.STOCK STATUS

STOCK ASSESSMENT

Last updated on 26 March 2011

Most recent assessment uses a new model based around length rather than age. Therefore, it ignores size differences within an age class. Also catch sampling prior to 1988 is limited.

SCIENTIFIC ADVICE

Last updated on 26 March 2011

Scientific advice has generally been followed. However catch and quotas are only for the Canadian portion of the stock and do not reflect additional removals by the US.

REFERENCE POINTS

Last updated on 26 March 2011

Precautionary and statistically meaningful limit and target reference points have been established for this stock. Harvest levels have been in-line with the reference points and stock status has improved as a result.

CURRENT STATUS

Last updated on 26 March 2011

Stock is well above both target and limit biomass reference points.Fishing rate is well below the level needed to be sustainable. Recruitment in recent years has been above average.

TRENDS

Last updated on 26 March 2011

Information from both modeling and research surveys indicates an increase in the abundance of the stock.Recent good recruitment is expected to further increase that abundance in later years.

2.MANAGEMENT QUALITY

MANAGERS' DECISIONS

Last updated on 26 March 2011

Managers have set quotas which are appropriate given the scientific information and the long lived nature of the stock. However some accounting of non-Canadian catch should be formally examined when setting quotas.Gear and seasonal closures are in effect.

RECOVERY PLANS

Last updated on 26 March 2011

Stock is fully recovered and biomass is well above reference points.A formal rebuilding strategy is not in place at this time, but could be implemented should the stock experience reductions in biomass or an increase in fishing mortality.

COMPLIANCE

Last updated on 26 March 2011

Harvesters comply with quotas. Even with US catch, quotas have not been exceeded since 2004.Discards are minimal in the directed long line fishery. This species is an incidental catch in the trawl fishery.

FishSource Scores

SELECT SCORES

MANAGEMENT QUALITY

As calculated for 2009 data.

The score is ≥ 8.

A precautionary harvest control rule (and adequate limit and target reference points) are in place anticipating no direct fishing should biomass drop to limit reference point levels.

As calculated for 2009 data.

The score is ≥ 6.

In general managers comply with scientific advice but the extent to what advice is independent from management decisions and how it is taken into account in those is not fully clear.

As calculated for 2009 data.

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

The Landings is 2.08 ('000 t). The Set TAC is 1.70 ('000 t) .

The underlying Landings/Set TAC for this index is 122%.

STOCK HEALTH:

As calculated for 2009 data.

This measures the SSB as a percentage of the SSBmsy.

The SSB is 6.50 ('000 t). The SSBmsy is 4.90 ('000 t) .

The underlying SSB/SSBmsy for this index is 133%.

As calculated for 2009 data.

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

The F is 0.200 (age-averaged). The F management target is 0.360 .

The underlying F/F management target for this index is 55.6%.

HUMAN RIGHTS ABUSE RISK

High Medium Low

This indicates the potential risk of human rights abuses for all fisheries operating within this stock or assessment unit. If there are more than on risk level noted, individual fisheries have different levels. Click on the "Select Scores" drop-down list for your fisheries of interest.
