There is good news and bad news for people who care about blue crabs in the Chesapeake Bay, judging by the latest winter dredge survey, conducted jointly by Maryland and Virginia.
The results of the annual blue crab winter dredge survey were released Monday. It estimates that the number of blue crabs in the Chesapeake Bay in 2026 is slightly lower than it should be, but higher than it was the previous year. So, the survey estimates a total of 349 million blue crabs in the bay, where the long-term average is 400 million. This is a 46% increase over last year’s estimate of 238 million crabs, which was the second-lowest number recorded since the survey’s start in 1990.
On the bright side, the number of juvenile blue crabs increased significantly after having six straight years of below-average numbers. Adult male numbers are also up. These are both encouraging signs.
Adult female crabs, however, continued to decline and remain well below average. They are now only just above the overfished “threshold” used by Chesapeake Bay fisheries’ scientists and managers to gauge the health of the crab population and whether to take active steps towards conservation. Females can bear millions of eggs, so they are key to increasing the overall population.
“Despite a concerning long-term trend, this year’s winter dredge survey results fortunately show a promising bump in the number of both juvenile and male blue crabs,” said Chris Moore, executive director of Chesapeake Bay Foundation Virginia, said in a statement. “This could be a preview for bountiful crabbing businesses and crab feasts this summer. However, the Bay’s important adult female crabs experienced another year of decline. And there’s still immense uncertainty surrounding the health of blue crabs in the Chesapeake Bay.”
Scientists are finalizing a multi-year draft stock assessment of the Chesapeake Bay blue crab, charting the species’ decline since 2011. The assessment doesn’t land on one clear reason for the decline in population, but it provides Maryland and Virginia with crucial data to help them make informed decisions on blue crab harvest in the future.
“To support a strong blue crab population, the focus needs to remain on three fronts: preventing pollution, restoring important blue crab habitats such as underwater grasses and oyster reefs, and tackling the growing threat of blue catfish,” Moore said. “We will work with fisheries managers and jurisdictions around the region to chart a brighter course for the Bay’s most iconic species … The results of this year’s winter dredge survey, along with the soon-to-be-released blue crab stock assessment, will be key.”
