"Herring seek shallow fingers of watersâditches, millponds, creeks with sometimes only two to three inches of water,'' Manooch says. But often the fish find access to these natal streams cut off by bridges, highways, building projects and beavers. And what man hasn't altered, he's polluted, Manooch says. The discharge from industries and waste treatment plants and the runoff from farms, forests, city streets and backyards funnel nutrients into the sluggish Chowan and swifter Roanoke. During sultry North Carolina sum- mers, the nutrients trigger blue- green algal blooms that choke the Chowan River. The blooms, Manooch says, are sometimes toxic to the fish. Other times they rob the river of needed oxygen or crowd out tiny plants the herring find more edible. "Anadromous fish populations are declining because they must come upriver to spawn and this deeply con- nects them with man," Manooch says. "And man has not been kind to ; Lee Wynns, co-owner of Perry- Wynns Fishery Co., once the nation's largest herring processing plant, also speaks disparagingly of the quality of the Chowan water that runs beneath his shoreside plant. "Herring are just like you and me," he says. "If we're traveling, we'd rather stay at a clean place than a dirty ; But once the herring return to the ocean, they have faced another prob- lem: fishing pressure created by fleets of huge factory ships capable of net- ting and processing enormous catches. Foreign fleets scooped up tons of the fish during the late 1960s and early Fishery managers blamed these factory ships for the initial, sharp decreases in North Carolina landings later in the decade. Seeing the effects of the high sea heists, state and fed- eral managers restricted offshore fishing. But by then the damage was done. Perry-Wynns' vats no longer brimmed wi
