For decades on the U.S. Mid-Atlantic coast, recreational anglers have braved the cold temperatures of late October and November to chase one of the region’s most iconic fish species, the striped bass. This season, just offshore of New Jersey and New York, the fall run was especially strong. “The amount of fish and [their size] was really, really high,” said Lou Van Bergen, a captain of Miss Barnegat Light, a 90-foot party boat out of Barnegat Light, New Jersey. “Every week, all the way through Thanksgiving, you could go out and catch nicer-sized fish.”

From the looks of the boat’s deck this fall, it would have been easy to assume that striped bass, once overfished to dangerously low numbers on the East Coast, had completed a remarkable comeback. Except that in the nearby Chesapeake Bay and in the Hudson River, where the fish return each spring to spawn, the hatching and maturation of juveniles “has been abysmal,” said John Waldman, an aquatic conservation biologist at the City University of New York. Waldman, an avid fisherman himself, called the low levels of striped bass recruitment, or spawning success, in these historically fertile estuaries “a real mystery.”
