June 3, 2025 — Atlantic cod is a classic New England fish, found everywhere from roadside fish-and-chip stands to the Massachusetts State House. Under the Magnuson–Stevens Act, NOAA Fisheries fosters the long-term biological and economic sustainability of marine fisheries, including rebuilding overfished stocks. Currently Atlantic cod is considered overfished and rebuilding plans are in place to promote population growth. We recently teamed up with recreational fishermen and other partners to learn more about this iconic species.
Advancements in Understanding Cod Populations
The latest model of cod stock structure based on scientific advances in genetics, tagging, and biological characterization shows there are five biologically distinct cod populations from New Jersey to Canada, and four stock units. This new model allows managers to better tailor management to the specific needs of each stock to help populations recover.
Recreational Biological Sampling Fills Data Gaps
In light of these advancements, stock assessment scientists needed more biological data from the recreational fishing fleet. NOAA Fisheries teamed up with members of New England’s recreational for-hire fleet, the New England Aquarium, Pelagic Strategies, and the Atlantic States Marine Fisheries Commission to fill those data gaps. The pilot study is called the Recreational Biological Sampling Program, or RecBio.
