Highighted items on the list are where Alosa sapidissima may be found.
Remarks Anadromous (Ref. 5951). Strongly migratory (tagged individuals caught as far as 3000 km from point of release); in rivers, moves up as far as Montreal, but usually not ascending as far upstream as A. pseudoharengus. Feeds on copepods, other crustacean zooplankters, aquatic insect larvae, especially chironomid larvae (important for young shad in fresh water); ostracods, amphipods, isopods, insects and small fishes in the Bay of Fundy (Ref. 5951). No feeding during migration up rivers. Parasites found are nematodes, distomes (trematodes) and acanthocephalans (Ref. 5951).
