Penobscot River Research Newsletter



The Penobscot River Science Exchange and its partners, the University of Maine, The Nature Conservancy, the Penobscot River Restoration Trust, and NOAA Fisheries, are pleased to announce the first edition of the Penobscot River Research Newsletter.  The newsletter is an annual summary of research projects on the Penobscot River and it is now available on-line here.


Covering 8,570 square miles, the Penobscot River is Maine's largest and New England's second largest watershed . Unfortunately, centuries of dam construction have blocked the migration of diadromous fish to their up-stream spawning and juvenile-rearing habitats, as well as altered the structure and function of fish assemblages throughout the river. 


The Penobscot River Restoration Project is a multi-million dollar endeavor to restore nearly 1,000 miles of sea-run fish habitat by removing  two large hydro-electric dams in the lower part of the river and providing improved fish passage at a third dam upstream.  In 2008, agency and academic researchers began conducting studies and environmental monitoring on the river in order to establish pre-dam removal conditions that will allow managers to document restoration outcomes.


The newsletter includes descriptions and photographs of over a dozen research projects including shortnose sturgeon movement and spawning, bird assemblages, sea lamprey movement in tributaries, iron-drainage impacts to water quality, alewife population structure and migration, marine-freshwater food web linkages, sea lamprey and Atlantic salmon interactions, and dam removal impacts on fish assemblages.


The Penobscot River Science Exchange meets twice annually to share and discuss river research plans and results. The Exchange is a collaboration with the Diadromous Species Restoration Research Network (DSRRN), a five-year, NSF-funded collaborative research effort to advance the science of diadromous fish restoration.  For information about the Exchange or DSRRN, please visit our website (www.umaine.edu/searunfish ) or contact the Editor at  barbara.s.arter@umit.maine.edu  or (207) 581-3286.
