Stock Assessments

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

  • This document presents a summary of the 2024 benchmark stock assessment for alewife and blueback herring, collectively referred to as river herring. The assessment was peer-reviewed by an independent panel of scientific experts through the Atlantic States Marine Fisheries Commission’s (ASMFC) external peer review process. This assessment is the latest and best information available on the status of the US river herring for fisheries management.

  • This assessment of the Atlantic Herring (Clupea harengus) stock is a management track assessment of the existing 2022 management track assessment conducted using the ASAP model. Based on the previous assessment, the stock was overfished but overfishing was not occurring. This assessment updated fishery catch data, survey indices, life history parameters (e.g., weights-at-age), and the ASAP assessment model and reference points (BRPs) through 2023. No significant changes were made to the methods in this assessment.

  • This assessment of the Black Sea Bass (Centropristis striata) stock is a Level-2 2024 management track assessment which updates the 2023 research track assessment model using the WHAM framework to fit a spatially explicit model specified for two regions, North or South of Hudson Canyon.

  • This document summarizes the 2024 stock assessment update for horseshoe crab. The assessment is an update to the 2019 benchmark stock assessment and extends the fishery-independent and -dependent data for horseshoe crab through 2022, reruns the models, and determines stock status.

  • The purpose of this assessment is to update the 2019 Horseshoe Crab Benchmark Stock Assessment (ASMFC 2019) with recent data from 2018-2022 and evaluate the current status of horseshoe crabs along the US Atlantic coast. This coastwide assessment is different from the Adaptive Resource Management (ARM) Framework, which evaluates the population in the Delaware Bay and recommends harvest with consideration for migratory shorebirds.
