Chesapeake Bay 2025 Young-of-Year Striped Bass Survey:
Slight improvement documented, but spawning success is still below average

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.

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.

Biologists captured more than 36,000 fish of 55 different species while conducting this year’s survey. Positive findings include three important forage species that were documented in abundance during the survey. Atlantic menhaden and bay anchovies were widespread in the Bay for the third consecutive year. Atlantic silversides were plentiful compared to last summer. These species are vital to the ecology of the Bay as a food source for many other species of fish and wildlife. Read more.
