Stock Assessments

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

  • 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).

  • This assessment of the Southern New England Mid-Atlantic winter flounder (Pseudopleuronectes americanus) stock is an operational assessment of the existing benchmark assessment (NEFSC 2011), and follows operational updates in 2015 and 2017. In each assessment since the benchmark the stock was overfished, but overfishing was not occurring (NEFSC 2015, 2017). The current assessment updates commercial fishery catch data, recreational fishery catch data (using new MRIP calibrated data), research survey indices of abundance, and the analytical ASAP assessment models and reference points through 2019. Additionally, stock projections have been updated through 2023.

  • This assessment of the Gulf of Maine winter flounder (Pseudopleuronectes americanus) stock is a management track assessment of the existing 2017 area-swept operational assessment (NEFSC 2017). Based on the previous assessment the biomass status is unknown but overfishing was not occurring. This assessment updates commercial and recreational fishery catch data, research survey indices of abundance, and the area-swept estimates of 30+ cm biomass based on the fall NEFSC, MDMF, and MENH surveys.

  • This document presents a summary of the benchmark stock assessment for American shad. The assessment was prepared by the Atlantic States Marine Fisheries Commission’s (Commission) Shad Stock Assessment Subcommittee (SAS) and peer-reviewed by an independent panel of scientific experts through the Commission’s external review process.
