Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 50.0 cm TL male/unsexed; (Ref. 5217); common length : 35.0 cm TL male/unsexed; (Ref. 5217); max. published weight: 900.00 g (Ref. 3277)
Adults are found over soft bottoms of the continental shelf, often inshore and in estuaries. Also pelagic and encountered throughout the water column (Ref. 9626). May feed on plankton by ram-filtering. Juveniles feed mainly on planktonic crustaceans and chaetognaths, to a minor extent on benthic crustaceans and polychaetes, besides scales taken from larger fishes (Ref. 30206, 40402). Mature females generally spawn in summer. Eggs are pelagic (Ref. 35237). Marketed mostly fresh.
