Adults usually in schools inhabit coastal waters (Ref. 3573); sometimes in lagoons and estuaries (Ref. 59043). Juveniles around 2.0 cm SL move to coastal lagoons and estuaries in summer and autumn (Ref. 59043). Adults are herbivorous feeding on algae and vegetal detritus while juveniles feed on zooplankton until about 3 cm SL, then on benthic organisms until 5 cm SL (Ref. 9987, 59043). Reproduce in summer (Ref. 2804). Oviparous, eggs are pelagic and non-adhesive (Ref. 205). Utilized for roe, but also fresh, smoked and frozen (Ref. 9987).
