About the River Herring Network

 

What is the network?

The River Herring Network brings together the wide range of stakeholders working on river herring management, research, restoration, and monitoring in the Gulf of Maine. Long-term stewardship of this important resource is only possible if we work together, at the scale at which river herring runs exist: stream to stream, pond to pond, and community to community. The network provides a forum for regular communication, trust-building, and identification of collaborative opportunities to advance our collective goals.

 
 

Vision

Healthy river herring runs across the Gulf of Maine that support coastal communities and ecosystems.

Mission

Advance collaborative research and co-management of river herring in the Gulf of Maine

 

Current Initiatives

Gathering river herring count data

Understanding the sustainability of the river herring fishery and the impact of restoration efforts on river herring populations relies on monitoring at individual runs across the region. These runs are monitored by community volunteers, town alewife committees, harvesters, the state, hydropower companies and other dam owners. The data from these count efforts is critical to answering a variety of questions about river herring populations, but the data are not easily found in one place. For runs that are commercially harvested, the count information is proprietary, and can only be shared with permission from the harvester or town. The River Herring Network identified collecting count data from as many runs as possible as possible as a priority activity, with the goal of sharing information and improving data access and transparency. This is currently a pilot effort with daily count information from a sample of 2022 river herring runs across the state of Maine captured in this dashboard.

Continuous temperature monitoring at river herring runs

Temperature is thought to be the primary driver of adult river herring migration into freshwater streams and ponds in the spring. However, there is considerable variation in life history across different runs, and the drivers of migration timing can vary from year to year, with flow rate playing an important role in addition to temperature. The River Herring Network deployed 21 temperature loggers across 7 runs (at the fishway, pond/lake outlet, and head of tide) for the 2022 run to help answer questions about run timing and life history dynamics. We aim to expand this pilot monitoring effort into more runs in future years, and potentially add flow meters alongside the temperature loggers. Ultimately, this temperature data will be added to the SHEDS Stream Temperature Database.

  • Bailey Bowden

    Chair | Town of Penobscot Alewife Committee

    I have observed and recreationally harvested alewives from the Bagaduce River for over 50 years. While counterintuitive, I believe that a well regulated co-managed commercial river herring harvest is a critical to the sustainability of the resource. I am very curious about juvenile river herring development in the fresh water and estuarine environments.

  • Michael Brown

    Maine Department of Marine Resources Sea-Run Fisheries Division

    I have been involved with river herring harvest and restoration in one form or another since the 1970s'. The most rewarding aspect remains working with the core group of dedicated volunteers and the Alewife Harvesters of Maine which developed a sustainable fisheries plan that allows some commercial harvest of river herring in light of the current moratorium on commercial river herring fisheries. I envision the River Herring Network playing an important role in bringing multiple interest together to continue the conservation and restoration work required to keep sustainable river herring populations on the landscape.

    Faculty, Ecology & Biology | College of the Atlantic

    Chris has been a biology professor at College of the Atlantic in Bar Harbor, Maine since 1990. His research interests include fish behavioral ecology and reproductive biology, as well as the interface between fishing, fishers, and fishing communities. His research in Maine focuses on population biology and co-management of shellfish and reproductive timing of marine species.
