Atlantic Salmon Smolt Survey Underway

This year marks 27 years of collaboration with Maine Department of Marine Resources to monitor Atlantic salmon migrating down Maine’s Narraguagus River to the ocean. From late April to early June, NOAA Fisheries uses screw traps to estimate the number of smolts exiting the river and collect other biological data. Long-term monitoring surveys like this help us understand how climate change impacts the timing of smolt migration. The team developed a model that linked fish movements to temperatures near juvenile salmon nursery areas. This study provides managers with a tool to annually refine protective measures at dams.
