Ecology of Alosa fallax
 
Main Ref. Whitehead, P.J.P., 1985
Remarks In freshwater, juveniles feed on planktonic crustaceans, rotifers and insects (Ref. 35387). In estuaries they consume mysids, isopods, and amphipods (Ref. 42360). In the sea, adults feed mainly on small fishes and on crustaceans, including euphausiids (Refs. 188, 42360). Although feeding generally ceases during spawning migrations (Ref. 59043), some male individuals were found to feed on copepods, isopods, fishes and insects (Ref. 89633).
