Publications:2024 Blue Crab Advisory Report

Last updated: May 27, 2026

This report summarizes the results of the 2022 and 2023 Blue Crab Winter Dredge Survey, conducted from December to March by the Maryland Department of Natural Resources (MDNR) and the Virginia Institute of Marine Science (VIMS). This report estimates the abundance of blue crabs in the Chesapeake Bay. The information in this report is used to assess blue crab stock status relative to female-specific management reference points.

What do blue crabs eat? Blue crabs are opportunistic omnivores. They will eat nearly anything they can find, including bivalves, dead fish, plant and animal detritus, and even other crabs!

Stories:Blue crabs at sustainable levels

Last updated: January 30, 2023

A new report on the Chesapeake Bay's blue crab population reveals a blue crab stock that has reached sustainable levels and is not overfished. A stable blue crab population means a more stable Bay economy, with watermen employed, restaurants stocked, and recreational crabbers—and crab-eaters—happy. The report, developed by the Chesapeake Bay Stock Assessment Committee (CBSAC) and released Friday by the Chesapeake Bay Program's Sustainable Fisheries Goal Implementation Team, highlights the health of a blue crab population with results showing a sustainable number of adult females and more juveniles than have been counted in the past two decades.

Stories:2026 Blue Crab Advisory Report shows below-average population, but no overfishing

Last updated: June 30, 2026

Blue crab survey results showing an increase in the Chesapeake Bay’s overall population were good news to seafood lovers and scientists alike. But experts continue to monitor and analyze data about this iconic species.  In June, members of the Chesapeake Bay Stock Assessment Committee released their 2026 annual Blue Crab Advisory Report with recommendations on how to maintain the fishery.

Stories:Denser grass beds hold more blue crabs

Last updated: January 30, 2023

Denser grass beds in the Chesapeake Bay could boost the region’s blue crab population, according to a new report from the Virginia Institute of Marine Science (VIMS). While researchers have long known that blue crabs use grass beds as sheltered nurseries and feeding grounds, this study is the first to show that denser, higher-quality grass beds hold more crabs than open beds where patches of mud or sand separate plants. These findings are based on fieldwork conducted between 2007 and 2008, during which scientists used a powerful vacuum to collect blue crabs from 104 sites along the shores of the lower Bay.

Stories:Adult female blue crab abundance rises 92 percent in 2016

Last updated: July 22, 2022

The Chesapeake Bay’s adult female blue crab population has increased 92 percent since the population was surveyed last winter. While the current adult female blue crab abundance of 194 million is well above the overfishing threshold, it remains below the 215 million abundance target. Maryland and Virginia estimate the Bay’s blue crab population through an annual winter dredge survey.

Stories:Chesapeake Bay blue crab population remains healthy and sustainable, despite population decline

Last updated: January 30, 2023

According to the 2020 Chesapeake Bay Blue Crab Advisory Report, the blue crab population in the Bay decreased from 594 million in 2019 to 405 million in 2020. While this marks an 31% decrease from the previous year, experts report the overall Chesapeake Bay blue crab population is not depleted or being overfished. The juvenile blue crab population—crabs that will grow to harvestable size this fall—was estimated to be 185 million, down from 324 million in 2019.

Stories:Maryland, Virginia Report Decreased Female Crab Harvest in 2008

Last updated: July 22, 2022

Watermen in Maryland and Virginia caught fewer of the Bay’s female blue crabs in 2008, achieving the targeted reduction of 34 percent set by the governors of the two states last spring, according to preliminary harvest data released by both states. Virginia officials announced last month that the state’s watermen hauled in 9.4 million pounds of female crabs from the Bay -- a 37 percent decline from the average catch in 2004-2007. The total blue crab harvest fell by 29.5 percent in the Virginia portion of the Bay.

Stories:Bay Blue Crab Population Increases Significantly

Last updated: July 22, 2022

Scientists estimate that a total of 400 million blue crabs overwintered in the Bay in 2008-2009, up from 280 million in 2007-2008, according to data from the latest Bay-wide winter dredge survey conducted by the Maryland Department of Natural Resources and the Virginia Institute of Marine Science. The overall abundance of adult crabs in 2008-2009 is estimated to be about 240 million crabs, slightly more than the interim target level of 200 million set by the Chesapeake Bay Stock Assessment Committee in early 2008. The increase in adult crab abundance is due primarily to a near doubling of adult females, coupled with a 50 percent increase in adult male abundance.

Stories:Photo Essay: The blue crab winter dredge survey completes its course

Last updated: July 22, 2022

From December to March, assessing the health of the Chesapeake Bay’s blue crab population means long stints on the water for scientists from the Virginia Institute of Marine Science (VIMS). Every year the blue crab winter dredge survey samples 1,500 randomly-chosen sites divided equally between Virginia and Maryland waters, in a partnership between VIMS and the Fisheries Service of the Maryland Department of Natural Resources (DNR). The data provides a bay-wide estimate of blue crab populations that helps agencies determine how many can be harvested without hampering the recovery of one of the Chesapeake Bay’s defining resources.

Stories:Blue Crab Advisory Report Recommends Continued Conservation Measures

Last updated: July 22, 2022

A report recently released by the Chesapeake Bay Stock Assessment Committee (CBSAC) notes that the Chesapeake Bay’s blue crabs appear to be making a comeback, but recommends that the jurisdictions that manage the blue crab fishery continue to keep conservation measures in place. The 2010 Chesapeake Bay Blue Crab Advisory Report cites the success of recent measures to control blue crab harvest and emphasizes the need for these conservation efforts to continue into the future. The annual winter dredge survey completed in April estimated that there are 315 million harvestable adult crabs in the Chesapeake Bay, an increase of 41 percent from 2009.
