Earthjustice, NRDC, Fishing, and Watershed Groups File Notice to Sue for ESA Protection of Imperiled River Herring
River herring spend most of their lives in the Atlantic Ocean. They are anadromous fish species, which means they return to spawn in coastal rivers in the spring. But these small fish are in big trouble. Based on analysis by the National Marine Fisheries Service, their populations have declined more than 98 percent from their historic level.
