Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 7; Raggi dorsali molli (totale) : 10 - 11; Spine anali: 1; Raggi anali molli: 10 - 12. Scales on predorsal midline 13-20, usually 15-18; scales in horizontal series 46 to 51, usually 48-49; breast scaled; belly anteriorly with small naked patch next to pelvic base (Ref. 34009).
Occurs inshore (Ref. 4343) and enters brackish and fresh water along the upper tidal zone of rivers (Ref. 12693). Larvae spend time in the marine zooplankton and as juveniles, about 135 days old, recruit to freshwater streams where they undergo rapid growth and morphological changes neceassary for upstream migration to the adult habitat (Ref. 51037). Marketed fresh in mixed catches (Ref. 12693).
