The purpose of this assessment was to evaluate the current status of Atlantic menhaden as a single-species along the U.S. Atlantic coast.
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.

This document presents a summary of the 2019 stock assessment update for weakfish. This assessment update used the new, calibrated estimates of recreational catch from the Marine Recreational Information Program (MRIP) and added three more years of data to the benchmark assessment model.

Based on the results of the most recent stock assessment update, the northern shrimp stock in the Gulf of Maine was depleted in 2018, with spawning stock biomass (SSB) at extremely low levels since 2013 (Hunter et al. 2018). The traffic light analysis of 2019 data indicated no improvement in status in 2019, with indices of abundance, biomass, and spawning stock biomass at new time-series lows, and recruitment the third-lowest in the time series, well below the 2018 level.

The Bayesian statistical catch-at-age assessment model for weakfish was updated with data through 2017. This included the new, calibrated MRIP estimates of recreational catch for the entire time series.
