This document presents a summary of the 2019 benchmark stock assessment for Atlantic cobia. This assessment was prepared through the Southeast Data, Assessment, and Review (SEDAR) process, and it includes new years of data and recalibrated estimates from the Marine Recreational Information Program (MRIP). This assessment is the latest and best information available on the status of the Atlantic cobia stock for use in fisheries management.
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.

SEDAR 58 addressed the stock assessment for Atlantic Cobia. A Stock ID Workshop was held June 5-7, 2018 in Charleston, SC. The Data Workshop was held April 1-5, 2019 in Charleston, SC. The SEDAR 58 Assessment Process was conducted through a series of webinars held from April to October 2019. The Review Workshop (RW) took place November 19-21, 2019 in Beaufort, NC.

The report is the culmination of a two-year effort to gather and analyze available data for Atlantic menhaden from the fishery-independent sampling programs of the Atlantic States, commercial purse-seine reduction fishery, and commercial bait fishery. ASMFC developed the stock assessment through its Atlantic Menhaden Technical Committee (TC) and Stock Assessment Subcommittee (SAS).

The development and peer review of the 2019 Atlantic Menhaden Stock Assessment occurred through a joint Atlantic States Marine Fisheries Commission (ASMFC) and Southeast Data, Assessment, and Review (SEDAR) process.

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.
