This assessment of the Southern New England Mid-Atlantic Winter Flounder (Pseudopleuronectes americanus) stock is a management track assessment update of the existing benchmark assessment (NEFSC 2011), and follows management track updates in 2015, 2017, 2020, and 2022. In each assessment since the benchmark, except for 2022, the stock was overfished, but overfishing was not occurring (NEFSC 2015, 2017, 2020, 2022). In the 2022 management track, stock status changed to not overfished due to a change in the recruitment stanza used to calculate biological reference points. The current assessment updates commercial fishery catch data, recreational fishery catch data, research survey indices…

Tautog is assessed and managed in four stock regions: the Massachusetts-Rhode Island (MARI) region, the Long Island Sound (LIS) region, the New Jersey-New York Bight (NJ-NYB) region, and the Delaware-Maryland-Virginia (DMV) region. This stock assessment is an update to the existing benchmark assessment for tautog (ASMFC 2015, ASMFC 2016); the previous assessment update was completed in 2021 (ASMFC 2021). This assessment updates the accepted statistical catch-at-age model for each region with commercial and recreational fishery catch data and indices of relative abundance from fishery-independent and fishery-dependent data sources through the terminal year of 2024

The purpose of this assessment was to update the 2020 Atlantic Menhaden Single-Species Benchmark Stock Assessment (SEDAR 2020a) and recent stock assessment update (ASMFC 2022) with data from 2022-2023. The stock assessment update reran the peer-reviewed BAM with a terminal year of 2023. As part of the assessment process, the Atlantic Menhaden Stock Assessment Subcommittee (SAS) identified an error in the publication used to estimate the natural mortality rate used in the assessment. The SAS developed a revised estimate of M to use in the base run of the assessment, which was lower than the estimate used in the 2020…
