Striped Bass Decline: Chesapeake Juvenile Index Hits 8th Straight Below-Average Year, With Stakes for New England

The striped bass decline that has worried New England anglers for years is not over. Maryland’s 2026 juvenile striped bass survey, the closest thing the East Coast has to an early forecast for future stripers, came in at 5.5, the best result since 2018 but the eighth straight year below the long-term average of 10.8, the Maryland Department of Natural Resources said.

That matters in Massachusetts because the fish caught off Cape Cod, the North Shore and Boston Harbor are born far to the south. Roughly 80% of the coastwide striped bass population spawns in the Chesapeake Bay, according to the Chesapeake Bay Foundation.

What the 2026 survey found

Maryland biologists sampled 22 sites in four major spawning areas, the Choptank, Nanticoke and Potomac rivers and the upper Chesapeake Bay, visiting each three times over the summer with a 100-foot beach seine. The index is the average number of juvenile striped bass 3 inches or smaller caught per sweep, across 132 sweeps. This year the crews caught 723 young striped bass, along with nearly 72,000 fish of 61 species. The upper Bay and Choptank River did best, and the young fish were more widely spread than in recent years, the department said. The survey has run since 1954.

In Virginia, the Virginia Institute of Marine Science recorded an index of 9.52, up from 5.12 in 2025 and slightly above the state’s historical average of 7.77, the Chesapeake Bay Foundation said. VIMS called the 2026 class an “average” year, coming after three straight below-average years.

By the numbers: better, but still about half of normal

By The Boston Report’s calculations, Maryland’s 5.5 is about 51% of the long-term average, so this year’s crop of young fish is still roughly half what the Bay historically produced. It is up about 38% from 4.0 in 2025 and nearly triple the 2.0 recorded in 2024. Virginia’s 9.52 is about 23% above its own average and 86% higher than last year. The two states use different survey methods, so each index should be compared with its own history rather than with the other state’s.

“Maybe [the 2026 findings] could be the beginning of a trend, a slow and steady improvement,” Carrie Kennedy, who oversees tidal fisheries data collection for Maryland DNR, told the Bay Journal. “However, eight years is pretty concerning for having a below average [index].”

Why young stripers are struggling

Maryland officials said a cold winter helped, but a prolonged regional drought and low river flows likely hurt eggs and larvae, which need strong flows to stay suspended in the water and reach food. The Chesapeake Bay Foundation pointed to warmer water, habitat loss, food availability and invasive predators such as blue catfish. Kennedy told the Bay Journal that researchers are finding plenty of eggs and larvae, but that is not translating into more young fish. There was good news for the food web: young Atlantic menhaden were abundant, and Atlantic silversides were found in their highest numbers in more than a decade, according to DNR.

The adult population is in better shape for now. DNR said recent estimates show healthy numbers of adult striped bass, and Kennedy noted that the spawning stock has been increasing. The risk is that eight weak year classes will show up in the adult population as those fish mature.

What it means for New England anglers and seafood lovers

The Atlantic States Marine Fisheries Commission, which manages striped bass from Maine to North Carolina, has set a 2029 deadline to rebuild the stock. Its striped bass board meets at the commission’s annual meeting on Nov. 11 but will not consider new regulations, according to the Chesapeake Bay Foundation. A new coastwide benchmark stock assessment is expected to finish peer review in spring 2027, and Maryland DNR said continued low reproduction will influence future conservation measures.

In Massachusetts, recreational anglers are limited to one striped bass a day in a slot of 28 inches to less than 31 inches, under state rules. Maryland closed striped bass fishing for all of August this year, when hot water makes caught-and-released fish more likely to die, and Virginia allows anglers to target the fish only from fall through spring. Tighter coastwide limits remain possible after the 2027 assessment, which could affect both charter trips and the local catch that ends up in Boston seafood markets.
