Stock Assessments

Scientific evaluations of fish stock status, providing critical data on population sizes, health, and trends to inform management decisions.

  • This document provides an overview of the 2021 stock assessment update for tautog (Tautoga onitis), which includes four regional stock assessments. The update uses the assessment methodology that was approved for management use as part of the 2016 Regional Benchmark Stock Assessment and subsequently used in the 2017 update.

  • Cooperative interstate management of Jonah crab (Cancer borealis) in U.S. waters was first implemented in 2015 with the adoption of the Atlantic States Marine Fisheries Commission’s (ASMFC) Interstate Fishery Management Plan (FMP; ASMFC 2015). However, there has been no stock assessment of U.S. Jonah crab to date, stock status is unknown, and there has been limited science-based advice available to support management of Jonah crab fisheries

  • This document summarizes the 2020 assessment updates for the Gulf of Maine (GOM) and Southern New England/Mid-Atlantic (SNE/MA) winter flounder stocks. Both assessments update the 2011 Benchmark Stock Assessments that were peer-reviewed by an independent panel of scientific experts at the 52nd Northeast Regional Stock Assessment Workshop/ Stock Assessment Review Committee (SAW/SARC 52) meeting.

  • This document includes: (1) a summary of the ARM Revision results supported by the Peer Review Panel. The Terms of Reference Report (TOR) provides a detailed evaluation of how each TOR was addressed by the ARM Subcommittee and provides recommendations from the Panel for further improvement of the model in the future; (2) additional information and analysis requested by the Peer Review Panel during the Peer Review Workshop; and (3) ARM Revision report that describes the background information, data used, and analysis for the assessment submitted to the Peer Review Panel.

  • This 2021 Management Track Assessment (MTA) of summer flounder (Paralichthys dentatus) is an update through 2019 of the commercial and recreational fishery catch data and research survey indices of abundance. Assessment model estimates of stock size and fishing mortality are updated through 2019.

  • This 2021 Management Track Assessment (MTA) of scup (Stenotomus chrysops) is an update through 2019 of the commercial and recreational fishery catch data and any available research survey indices of abundance. Assessment model estimates of stock size and fishing mortality are updated through 2019.

  • Commercial bluefish landings in 2019 were 1,381 MT = 3.05 million lbs, an increase of 25% from 2018, and 40% of the 2019 commercial quota (3,497 MT, 7.71 million lbs).
