The Atlantic States Marine Fisheries Commission’s Winter Flounder Technical Committee conducted a winter flounder otolith aging comparison study in 1998, to measure interpretative consistency among four readers (Appendix I). Bias measured by this study related to systematic differences detected among comparisons between readers, but did not address accuracy relative to true age.
Stock Assessments
Scientific evaluations of fish stock status, providing critical data on population sizes, health, and trends to inform management decisions.

The Section took emergency action to close the northern shrimp fishery on February 17, 2012. Because harvest had averaged about 400 mt per week and the fishery was known to have considerable late reporting, landings were projected to have already exceeded the total allowable catch (TAC) of 2,211 mt at the time of closure.
-
The updated stock assessment was completed by adding catch and indices through 2010 to the previous 1982-2009 assessment. The result of the analysis shows that bluefish is not overfished or experiencing overfishing.

The Southern Demersal Working Group (SDWG) prepared the stock assessment. The SDWG met during April 19-21, April 26-28, and May 3-5, 2011 at the Northeast Fisheries Science Center, Woods Hole, MA, USA.

This Assessment Report has been revised to reflect the changes in the assessment. Any changes to the document have been highlighted in yellow.

The assessment of GOM winter flounder stock is based on an empirical swept-area model utilizing data from the 2010 NEFSC fall survey, the MADMF fall survey, and the Maine-New Hampshire fall inshore survey.
-
In 2010 the SNE/MA winter flounder stock was overfished but overfishing was not occurring. The current assessment provides a new assessment model, a new assumption for the instantaneous natural mortality rate (M), and new biological reference points.
-
The coastwide tautog stock is overfished and overfishing is occurring relative to the biological reference points established in Addendum IV to the Fishery Management Plan for Tautog (ASMFC 2007).

This assessment of the scup (Stenotomus chrysops) stock along the Atlantic coast (Massachusetts to North Carolina) is an update through 2010 of commercial and recreational fishery catch data, research survey indices of abundance, and the analyses of those data.
