March 10, 2026 — Maryland officials are celebrating what they call one of the strongest years for oyster reproduction in decades, with new data showing a dramatic spike in juvenile oysters across Maryland waters.
Gov. Wes Moore announced Monday that the concentration of new oysters in 2025 was nearly six times higher than the long-term average and ranks as the second-highest level recorded in the 41-year modern history of the state’s annual fall oyster survey.
Reproduction Near 30-Year High
According to preliminary findings from the Maryland Department of Natural Resources (DNR), scientists recorded an average of 250 spat — juvenile oysters — per bushel at key monitoring sites. That figure is more than three times higher than the strong reproduction seen in 2023 and far above the long-term average of 42.2 spat per bushel. It marks the highest reproductive success since 1997.
