Biologie     Glossaire (ex. epibenthic)

Adults are neritic usually in schools, entering lagoons and lower estuaries (Ref. 7399); rarely entering freshwater (Ref. 3573, 59043). Juveniles move to coastal lagoons and estuaries in winter and especially in spring (Ref. 59043). They feed on small benthic organisms, detritus, and occasionally on insects and plankton (Ref. 2804). Juveniles feed only on zooplankton (Ref. 59043). Reproduction takes place in the sea, from July to November. Oviparous, eggs are pelagic and non-adhesive (Ref. 205). Minimum size allowed for fishing is 20 cm. The quality of the flesh is variable (Ref. 30578).
