Fisheries Science
Sustainable fisheries management depends on sound, timely scientific advice. The Fisheries Science Program delivers this through a rigorous, peer-reviewed stock assessment process, utilizing a mix of fishery-independent surveys and fishery-dependent monitoring, complemented by research from coastal state, federal, and academic institutions. The program also focuses on developing innovative scientific methods and enhancing state stock assessment capabilities, while coordinating and expanding collaborative research and data collection efforts.

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.

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 purpose of this document is to formalize the design and administration of the SATP, including definition of the program’s mission, goals, and expectations. A formalized program design captured in this guidance document will improve the functionality of the program and lead to greater benefits to ASMFC, its member agencies, and science based fishery management of Atlantic coast resources.

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.

At the behest of the ASMFC Bluefish Board, the Bluefish Technical Committee organized an ageing workshop to establish consistency and a common protocol of best ageing practices across state and university labs that process and read bluefish hard parts. Workshop participants also agreed to discuss the design of a coastwide sampling program intended to expand the geographical range of bluefish age samples and fill the gaps in the age-length key.

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.
