Abstract

River herring is a term applied collectively to both alewife, Alosa pseudoharengus, and blueback herring, A. aestivalis, anadromous fish that spend most of their life in the ocean and migrate upriver to freshwater to spawn each spring (NEFSC 2006). Juveniles spend their first summer in freshwater and are thought to migrate to the ocean in fall, where they remain until they are sexually mature and ready to spawn (three to five years; ASMFC 2012).
