The Maryland Department of Natural Resources’ (DNR) 2025 juvenile striped bass survey recorded a young-of-year index of 4.0. This is an improvement over recent years, but still well below the long-term survey average of 11. This marks the seventh consecutive year of low spawning success for striped bass. The annual survey tracks the reproductive success of Maryland’s state fish in Chesapeake Bay.
“Management actions taken over the last decade have resulted in a healthy population of spawning-age striped bass,” said Maryland DNR Fishing and Boating Services Director Lynn Fegley. “However, continued low numbers of striped bass entering the population is a threat to this progress as there are fewer juveniles growing into spawning adults. Maryland will continue working with partner states along the coast to ensure responsible management of striped bass given recent low reproduction rates.”
During this annual survey, fishery managers sample 22 sites located in four major striped bass spawning areas: the Choptank, Nanticoke, and Potomac rivers, and the upper Chesapeake Bay. Biologists visit each site three times per summer, collecting fish with two sweeps of a 100-foot beach seine net. The index represents the average number of 3-inch or less juvenile striped bass caught in each sweep of the net.
Similar fish surveys were conducted this summer in the Patapsco, Magothy, Severn, Rhode, West, and Tred Avon rivers, and St. Clements and Breton bays. Those surveys, which were conducted outside the annual survey locations, found even fewer young-of-year striped bass.

Signs like this one spotted along the highway outside Jarvis popped up throughout Haldimand County during Shelley Ann Bentley’s successful mayoral campaign in 2022. Some of the signs have stayed put ever since, conveying some residents’ continued opposition to building 15,000 homes on industrial land in Nanticoke. Photo by J.P.
