Maine Atlantic Salmon Trap Count Statistics

Maine Department of Marine Resources, Bureau of Sea-Run Fisheries and Habitat staff conduct routine monitoring of the abundance and status of adult Atlantic salmon and other fish species in many Maine rivers. MDMR Staff operates on the Penobscot River (Milford Dam), Androscoggin River (Brunswick Dam), and Narraguagus River (Cherryfield Dam). Brookfield Renewable Partners operates traps on the Kennebec River (Lockwood Dam), the Union River (Ellsworth Dam), The Penobscot River (Orono Dam) and at two hydroelectric projects on the Saco River (Skelton and Cataract Dams). The St. Croix Waterway Commission operates a trap at the Milltown Dam on the St. Croix River. Benton Falls Associates operates a trap on the Sebasticook River (Benton Falls Dam). Algonquin Power & Utilities Corp operates a trap on the Aroostook River (Tinker Dam). These fish counting facilities are typically operated from May through early November each year. Staff update the statewide trap catch summary weekly or more often during the peak of the fish migrations. The statewide trap catch table includes counts of sea-run salmon captured on Maine rivers and salmon removed from the river as broodstock for restocking of Maine rivers and DOES NOT include captures of aquaculture strays or captive reared adult salmon released from Federal hatcheries.
