| Predation - Micropterus dolomieu (Smallmouth Bass) is one of the major piscivorous species in nontidal tributaries and in upper reaches of major East Coast estuaries, including the Connecticut River. In New England rivers, it is considered a major predator of Atlantic Salmon juveniles (Salmo salar) (US Fish and Wildlife Service 1999). | ||
