Biologie     Verklarende woordenlijst (b.v. epibenthic)

Epipelagic (Ref. 58302). A schooling species living close inshore and entering bays, inlets, estuaries, canals and even penetrating into fish ponds, thus able to tolerate a wide range of salinities. Feeds mainly on planktonic crustacean larvae. Breeds throughout the year, with a peak in summer, spawning at night (between 2200 and 0200 hours) in bays and estuaries (Ref. 189).

Spawn in bays and estuaries in school (Ref. 205). Spawning is said to be continuous throughout the season (Ref. 32412, 40290).
