Summary

IDENTIFICATION

SCIENTIFIC NAME

Melanogrammus aeglefinus

SPECIES NAME(S)

Haddock

COMMON NAMES

Eastern Scotian Shelf haddock

There is an extensive research from demographic, recruitment, parasitic, genetic and tag-recaptures studies providing evidence for the identification of haddock stocks (Begg 1998). The major populations divisions occur between Nova Scotia, New England, and Newfoundland waters. Despite some uncertainty due to seasonal variations in the species´ spatial distribution, a number of discrete stocks are defined:

1) Grand Banks (Div.3LNO), 2) St. Pierre Bank (Div. 3Ps), 3) Eastern Scotian Shelf and Southern Gulf of St. Lawrence (Div. 4TVW), 4) Western Scotian Shelf (Div. 4X), 5) Georges Bank (Div. 5Zjm - Canada; Div. 5Z - USA), and 6) Gulf of Maine (Div. 5Y).


ANALYSIS

Strengths

Some rebuilding was apparent when the stock was last assessed in 2002.
Managers have set removals as close to zero as possible and instituted restrictive bycatch controls.

Weaknesses

Stock as last assessed in 2002 was in poor shape with little recruitment, slow growth, and high natural mortality.
Stock has not had a more recent update in status and as such the full scope and success of the restrictions cannot be measured.

RECOMMENDATIONS

CATCHERS & REGULATORS

1. Review the FishSource profile and publish or share online relevant missing information in your possession or those accessible to you.
2. Encourage scientists to share their studies/publications with FishSource by commenting on the profile and uploading a hyperlink to the document.
3. Work with scientists on the collection of data and make them accessible online.
4. Encourage the institutionalization of data collection and publication.

RETAILERS & SUPPLY CHAIN

1. Advise your suppliers that currently the FishSource profile reflects that there is not enough information publicly available on this fishery and you are unable to make an accurate determination of the sustainability status. Request that they advise the relevant authorities of the situation and that efforts need to be made to collect and publish data and disclose data sources to FishSource to better inform buying decisions.

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

Stock has not been assessed since 2002, and there is not directed fishery in place. As such there is no information on stock status.

Scientific Advice

Last updated on

As there has not been an assessment of a survey of this resource, there is not scientific advice given recently. The last assessment was in 2002 and is now 12 years old.

Reference Points

Last updated on

Reverence points are in place for this stock, however without a directed fishery or updated assessment these reference points have little meaning.

Current Status

Last updated on

The most recent assessment in 2002 categorized this stock as in poor shape, but showing some improvement. However the stock is in a low productivity regime, with high natural mortality, slow individual growth and very low recruitment (DFO, 2002).

Trends

Last updated on

Some indications of improvement in the status were available during the last assessment in 2002. More recent information is not available, and as such the status and trends of this stock are unknown.

2.MANAGEMENT QUALITY

Managers' Decisions

Last updated on

Managers have closed the directed fishery since 1993 after collapse of the stock. While there is some landings as a result of bycatch, there are restrictive bycatch measures in place and overall this removal level is very low.

Recovery Plans

Last updated on

Managers have attempted to recover this stock by setting F as low as possible, mandating strict bycatch controls and other measures. However until this stock is improved or until there is a directed fishery a formal recovery plan with targets and goals can not be constructed.

Compliance

Last updated on

Harvester have complied with the moratorium and bycatch is very low.
