Main Ref. Bond, W.A. and R.N. Erickson, 1993
Remarks Occurs in brackish waters (20-22 ppt) of coastal lagoons and mouths of rivers and bays (Ref. 4779). Nerito-pelagic (Ref. 58426). Enters rivers in shoals to spawn (Ref. 4779). Feeds on small crustaceans, insects, small fishes (Ref. 28219, 28857), worms and clams (Ref. 58426). No feeding occurs during the upstream migration (Ref. 4779). Collected by fyke nets (Ref. 4526).
