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 traffic light analysis of 2022 data indicated no improvement in status, with indices of abundance, spawning stock biomass, and recruitment at new time-series lows.

This document presents a summary of the 2022 stock assessment update for Atlantic striped bass. This is an update of the assessment model that was peer-reviewed by an independent panel of scientific experts at the 66th Northeast Regional Stock Assessment Workshop/Stock Assessment Review Committee (SAW/SARC66) meeting in November 2018 and includes data through 2021.

COVID-19 affected fishery-dependent and fishery-independent sampling for state surveys and the MRIP dockside intercept program, although the level of impact varied from state to state. The assessment model was able to accommodate the missing index data, but overall, COVID-19 increased uncertainty in the 2020 and 2021 data.

2022 Atlantic Striped Bass Stock Assessment Update Appendices
-
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, 2017, and 2020. In each assessment since the benchmark the stock was over shed, but overfishing was not occurring (NEFSC 2015, 2017, 2022). 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 2021. Additionally, stock projections have been updated through 2025.

This assessment of the Gulf of Maine winter flounder (Pseudopleuronectes americanus) stock is a management track assessment of the existing 2020 area-swept management track assessment (NEFSC 2022). 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.

The Peer Review Panel concluded that the 2022 assessment for Atlantic herring provides the Best Scientific Information Available as a basis for management decision making in the northeast.
