57th SAW Assessment Report
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 striped bass statistical catch-at-age (SCA) model used since 2007 has been generalized to allow, among other things, specification of multiple fleets, different stock-recruitment relationships, and year- and age-specific natural mortality rates. The changes in model structure and additions are based on recommendations of the 2007 benchmark review committee (NEFSC 2008).

In 2013, the Northern Shrimp Section increased the number of landings days for the trawl fishery from two to four. This was due to low landings since the start of the season and the desire to provide the trawl fishery with greater access to the resource.
