Salmon Trap Count Statistics

Adult Atlantic Salmon Trap Catch Summary

The Atlantic Salmon Commission (ASC) staff conducts routine monitoring of the abundance and status of adult Atlantic salmon in many Maine rivers. ASC staff operates traps at fishways and barrier weirs to monitor adult Atlantic salmon returns to the Penobscot (Veazie Dam), Narraguagus (Cherryfield Dam), and Dennys rivers (Dennysville weir); Great Lakes Hydro, America operates a trap at Weldon Dam in the upper Penobscot drainage, Pennsylvania Power and Light operates a trap at the Ellsworth Dam on the Union River; Florida Power and Light operates traps and lifts at two hydroelectric projects on the Saco River, Maine Department of Marine Resources operates one on the Androscoggin River, and the St. Croix Waterway Commission operates a trap at the Milltown Dam on the St. Croix River.

These salmon counting facilities are typically operated from May through early November each year. ASC staff updates the statewide trap catch summary weekly or more often during the peak of the salmon migration. 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.
