Predation on Atlantic Salmon Smolts by Striped Bass after Dam Passage
We documented predation on smolts of Atlantic salmon Salmo salar by striped bass Morone saxatilis foraging in the tailrace of the Essex Dam on the Merrimack River, Lawrence, Massachusetts, and assessed factors that may affect smolt susceptibility to predation. During 6 d of diurnal angling from 6 to...
