New York’s striped bass fishery, often overlooked by outsiders, enjoys a singular distinction: Sitting smack-dab in the middle of the annual migration, it’s ground zero for stripers. In April and May, Jamaica Bay is awesome. “Jamaica Bay is fishy, man,” notes Capt. Danny Reich. “All sorts of bait, structure, flats.” He’s right. The spring in particular can be off-the-charts. Jamaica Bay, part of the National Park system, holds 10,000 acres of protected salt marsh.
