Spatial and Temporal Patterns of Anadromous Alosine Bycatch in the US Atlantic Herring Fishery

River herring, which comprise two species of anadromous alosines (alewife and blueback herring), are under consideration for listing under the US Endangered Species Act. River herring populations have not rebounded despite reductions in directed fishing and improvements in their freshwater and estuarine habitats. We discuss possible management measure to reduce bycatches.
