Technical Expert Working Group for River Herring

On August 12, 2013, NOAA Fisheries announced that listing river herring under the Endangered Species Act as either threatened or endangered was not warranted. NOAA Fisheries also announced the agency would provide funding to the Atlantic States Marine Fisheries Commission (ASMFC) in order to work with our partners to implement a coordinated coastwide effort to proactively conserve river herring and address data gaps. The primary objective of this initiative is to develop and implement a dynamic conservation plan to help restore river herring throughout its Atlantic coastal range. This will include identifying important conservation efforts, identifying critical data gaps, and monitoring and evaluating progress in achieving the goals. This effort will coordinate and build upon the many previous and ongoing efforts to further river herring conservation, including fisheries work by the Mid-Atlantic Fishery Management Council (MAFMC) and the New England Fishery Management Council (NEFMC), and habitat restoration by the Atlantic Coastal Fish Habitat Partnership and The Nature Conservancy.

A Technical Expert Working Group (TEWG) has been established for river herring throughout both species’ range from Canada to Florida, and will be providing/compiling information that will be used by NMFS and ASMFC in the development of this conservation plan. The plan is intended to increase public awareness about river herring, stimulate cooperative research efforts, and inform efforts to conserve the species.  Given the many threats that river herring face, conservation of river herring must be holistic. Therefore, we have worked with various organizations to identify individuals who possess expertise related to river herring, threats to their survival, and/or methods for assessing human and non-human impacts to river herring (e.g., connectivity, water quality/quantity, climate change, etc.) to participate on the TEWG. The TEWG includes subgroups by topic to focus discussions,and an overarching committee comprised of chairs/co-chairs from the subgroups
