River herring are an important part of the marine, estuarine, and freshwater ecosystems, providing food for a variety of animals and including important commercial and recreational fish like cod and haddock, and providing nutrients derived in the marine environment to the freshwater habitats that they migrate to. In order to successfully restore river herring, it is important to increase the resilience of both species, therefore, the full array of interactions within the ecosystems that they occupy must be considered. Because of river herrings role in freshwater, estuary and marine foodwebs their restoration will likely afford significant ancillary benefits to a wide range of species, including other diadromous species.    

The river herring Technical Expert Working Group (TEWG)Ecosystem Integration Committee has discussed issues to ensure that an ecosystem perspective is taken to the TEWG. Due to the overlapping nature of many of the considerations for river herring, communication and collaboration is important in order to avoid duplication of efforts and utilize limited resources. The Committee provides a forum to integrate information across the subgroups to inform the overall NMFS and ASMFC’s conservation strategy for these species. Additional information on these discussions, including overlapping needs and ongoing efforts can be found at:
