October 19, 2026 — The following was released by the Maryland Department of Natural Resources:

The Maryland Department of Natural Resources’ (DNR) 2026 juvenile striped bass survey recorded a young-of-year index of 5.5. Although it marks the eighth consecutive year of low spawning success for striped bass, this is the highest index recorded since 2018. The survey tracks the reproductive success of Maryland’s state fish in Chesapeake Bay.

During this annual survey, fisheries biologists 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 smaller juvenile striped bass caught in 132 sweeps of the net. The survey, one of the longest-running continuous fish surveys in the United States, has been conducted in Maryland’s Chesapeake Bay since 1954.

This year’s survey captured 723 juvenile striped bass. The highest performing areas were the upper Bay and Choptank River. Although striped bass catches were below average, the fish were more widely distributed than in recent years, indicating suitable habitat throughout the nursery areas. The long-term average index for the survey is currently 10.8, while the index was 4.0 in 2025 and 2.0 in 2024. 

“We are encouraged to see some improvements to the numbers of juvenile striped bass this year, while it wasn’t as robust as we would like,” said Maryland DNR Fishing and Boating Services Director Michael Luisi. “Ongoing low recruitment is anticipated to impact rebuilding of the coastwide striped bass population. Results from coastwide juvenile indices will be incorporated into the ongoing work to produce the benchmark stock assessment expected to be completed in 2027.”

Biologists captured nearly 72,000 fish of 61 different species while conducting this year’s survey. Fishing license, tackle, boat, and marine fuel purchases fund DNR’s fish conservation work. Positive findings from the survey include two important forage species that were documented in abundance during the survey. Young Atlantic menhaden were found in abundance, while Atlantic silversides were found in the highest numbers in over a decade. These species are vital to the ecology of the Bay as a food source for many other species of fish and wildlife. Another encouraging finding was above-average reproduction of American shad in the Potomac River and upper Chesapeake Bay; however, the survey does not evaluate the larger, adult populations of these species.

Efforts to rebuild the Atlantic Coast population of striped bass to previous high levels have been underway for several years and are ongoing. Through the Atlantic States Marine Fisheries Commission, Maryland and other states that border the Atlantic Ocean have implemented management measures, including reductions to catch limits, tighter slot limits, and season closures. Continued low levels of reproduction will influence future conservation measures under consideration by the Atlantic States Marine Fisheries Commission.

Recent population estimates indicate healthy adult populations of striped bass, despite the downturn in juvenile spawning success. A rebuilt adult population should reproduce successfully when conditions like river flow, temperature and food availability are favorable for striped bass eggs and larvae.

Multiple factors affect striped bass spawning success in the Chesapeake Bay. Cold winters and wet springs tend to be beneficial for spawning, and while Maryland experienced a cold winter, the prolonged regional drought and resulting low river flows may have led to unfavorable conditions for striped bass eggs and larvae. High river flows increase spawning habitat,  allow eggs to remain suspended in the water column, and bring larvae closer to food sources. Other variables, including a shortened spawning period, could also influence spawning success.

These consecutive below-average year classes will likely become more apparent among the adult population of striped bass in the coming years, as the juveniles reach maturity. A benchmark stock assessment for the coastwide population of Atlantic striped bass is underway and expected to complete peer review in spring 2027. The stock assessment will evaluate the condition of striped bass from Maine to North Carolina and inform future management actions.

The Virginia Institute of Marine Science conducts a similar survey in the southern portion of Chesapeake Bay.
