Chesapeake Bay’s Blue Crab Population Holds Strong, Harvest Levels to Remain Unchanged

The 2024 Bay-wide Blue Crab Winter Dredge Survey results have revealed a stable blue crab population in the Chesapeake Bay. Encouraged by these findings, fisheries managers from Virginia, Maryland, and the Potomac River Fisheries Commission have decided to maintain current harvest levels while awaiting a comprehensive benchmark stock assessment.

Since 1990, the Virginia Institute of Marine Science and the Maryland Department of Natural Resources have conducted the annual Winter Dredge Survey. This survey uses traditional crab dredges to sample blue crabs at 1,500 sites throughout the Chesapeake Bay from December through March. The 2024 survey estimated the blue crab population at 317 million, with adult female crabs remaining above average for the second year.

Monitoring the adult female blue crab population is crucial, as they are essential for propagating future generations. The population has responded positively to management changes made after the 2008 Blue Crab Fishery Disaster declaration. Notably, there has been no overfishing of female crabs in 2024, continuing a positive trend.

Jamie Green, Commissioner of the Virginia Marine Resources Commission (VMRC), highlighted the importance of Virginia’s license-specific bushel limits: “One of the most influential management measures that has contributed to the long-term success in blue crab fisheries management has been the license-specific bushel limits implemented by Virginia in 2013. This allows Virginia to reduce regulatory burdens that would economically benefit the industry while maintaining the long-term conservation goals of the joint Chesapeake Bay jurisdictions.”

However, the Chesapeake Bay Stock Assessment Committee (CBSAC) has warned that other factors affecting blue crab abundance may not be fully understood. To address this, a collaborative effort supported by Virginia, Maryland, and the NOAA Chesapeake Bay Office is underway to conduct a comprehensive stock assessment over the next 2-3 years. This assessment will consider habitat availability, water temperature and salinity, ocean dynamics, and predator abundance, with the results informing future management strategies.

CBSAC recently reviewed the 2023-24 Winter Dredge Survey results, which will be detailed in the forthcoming CBSAC Annual Report, scheduled for release this June. In Virginia, stakeholders can learn more about the survey results at the Virginia Marine Resources Commission’s Crab Management Advisory Committee meeting on May 29 at 4 p.m. Additional information about public meetings can be found at MRC.Virginia.gov.
