SUMMARY

SUMMARY

IDENTIFICATION

SCIENTIFIC NAME(s)

Pseudopleuronectes americanus

SPECIES NAME(s)

Winter flounder


ANALYSIS

Strengths

Scientific advice to reduce harvest as low as possible is sound.
Federal managers have clear rebuilding goals
Federal management has successful reduced harvest levels including bycatch in other fisheries.

Weaknesses

Stock abundance at very low levels
State Management (ASMFC) is too liberal given stock health
Model used is overly optimistic given retrospective pattern
Stock is experiencing very low recruitment

Options

To meet management goals, stock should not be subjected to direct harvest
Encourage the continuation of precautionary federal management.
Suggest state management follow federal to help meet rebuilding goals

RECOMMENDATIONS

CATCHERS & REGULATORS

1. Start a fishery improvement project to address sustainability issues in this fishery. For advice on starting a FIP, see SFP’s Seafood Industry Guide to FIPs at http://www.sustainablefish.org/publications/2014/04/30/the-seafood-industry-guide-to-fips.
2. Communicate to fishery managers that there are sustainability issues in this fishery that may be affecting the sale of products, and request that they comprehensively evaluate and address such issues.

RETAILERS & SUPPLY CHAIN

1. Encourage your supply chain to start a fishery improvement project. For advice on starting a FIP see SFP’s Seafood Industry Guide to FIPs at http://www.sustainablefish.org/publications/2014/04/30/the-seafood-industry-guide-to-fips.
2. Work with other suppliers and buyers on a pre-competitive basis to start a supplier roundtable to review improvement needs in this and other similar fisheries, catalyze fishery improvement projects, and monitor progress in improvement efforts.

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
Southern New England/Mid Atlantic
United States
Bottom trawls

Last updated on 31 December 2012

Model shows a severe retrospective pattern and over-estimates biomass and under-estimates F in the current year (NMFS, 2011).

SCIENTIFIC ADVICE
Southern New England/Mid Atlantic
United States
Bottom trawls

Last updated on 31 December 2012

Recent changes to the model have shown stock to be in poorer health then previously thought(NMFS, 2011).

Reference Points

Last updated on 31 Dec 2012

Precautionary MSY based reference points are in place (NMFS, 2011).

CURRENT STATUS
Southern New England/Mid Atlantic
United States
Bottom trawls

Last updated on 31 December 2012

Stock is in poor condition and experiencing low recruitment (NMFS, 2011).

Trends

Last updated on 31 Dec 2012

Harvest has been dramatically reduced.Despite the reductions it is unlikely that the stock will meet its rebuilding goals due to low recruitment and liberalizations in state only commercial and recreational fisheries (NMFS, 2011).

2.MANAGEMENT QUALITY

MANAGEMENT
Southern New England/Mid Atlantic
United States
Bottom trawls

Last updated on 31 December 2012

Managers have recently started to follow scientific advice. prior to that managers set measures that were not consistent with stock rebuilding goals or sustainability. Managers often allow for more harvest for the recreational and commercial sectors in state waters (ASMFC)that scientifically justified given poor stock condition.

Recovery Plans

Last updated on 31 Dec 2012

A recovery plan is in place, but unlikely to be successful due to low recruitment and liberalizations in recreational and commercial state-only fisheries (NMFS, 2011).

COMPLIANCE
Southern New England/Mid Atlantic
United States

Last updated on 18 December 2012

Harvesters generally comply. The recreational sector of this fishery has grown in importance as commercial harvest has declined.Regulations in the recreational fishery are sometimes not followed.

FishSource Scores

MANAGEMENT QUALITY

As calculated for 2010 data.

The score is 9.4.

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

The F is 0.0500 (age-averaged). The F management target is 0.310 .

The underlying F/F management target for this index is 16.1%.

As calculated for 2010 data.

The score is < 6.

Federal Managers have followed the scientific advice, But state (ASMFC) managers have not. Quotas are not used in this fishery.

As calculated for 2010 data.

The score is ≥ 6.

Commercial harvesters have followed regulations.

STOCK HEALTH:

As calculated for 2010 data.

The score is 2.5.

This measures the SSB as a percentage of the Blim.

The SSB is 7.08 ('000 t). The Blim is 16.9 ('000 t) .

The underlying SSB/Blim for this index is 41.9%.

As calculated for 2010 data.

The score is 10.0.

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

The F is 0.0500 (age-averaged). The F management target is 0.310 .

DATA NOTES
Notes
Fishery is in poor shape. Managers have instituted stringent measures including no possession in federal waters and reductions on bycatch from other fisheries. In state waters, a low trip limit is in place for bycatch allowances, and the recreational sector has been reduced.
