Inhabit coastal marine waters and brackish estuaries (Ref. 3791); also found in hyper-saline lagoons and may enter freshwater (Ref. 5217). Never far from the sea (Ref. 3791). Form sizeable schools (Ref. 3791). Appear to undergo trophic migrations along the coasts (Ref. 35237). Feed on organic detritus and filamentous algae (Ref. 9626). Oviparous, eggs are pelagic and non-adhesive (Ref. 205). Spawn several million eggs (Ref. 35237) at sea (Ref. 3791). Also caught with beach nets (Ref. 5217). Marketed fresh and salted (Ref. 5217). The roe is marketed salt-pickled and dried and considered a delicacy (Ref. 5217).
