Sciaenidae (Drums or croakers)
Etymology: Argyrosomus: Greek, argyros = silvered, silver + Greek, soma = body (Ref. 45335); regius: A. hololepidotus in Ref. 57396 refers to A. regius and A. coronus based distribution and Ref. 11025..
Environment: milieu / climate zone / depth range / distribution range
Ecologia
marinhas; estuarina bentopelágico; oceanódromo (Ref. 51243); intervalo de profundidade 15 - 300 m (Ref. 2683). Subtropical; 65°N - 6°S, 23°W - 36°E

Comprimento de primeira maturação / Tamanho / Peso / Idade
Maturity: Lm ?, range 80 - ? cm
Max length : 230 cm TL macho/indeterminado; (Ref. 5377); common length : 150 cm TL macho/indeterminado; (Ref. 3593); peso máx. publicado: 103.0 kg (Ref. 11036)
Espinhos dorsais (total): 10 - 11; Raios dorsais (total): 27-29. Rough scales, Second dorsal fin (soft ray) twice as long as first, spiny rayed dorsal fin (Ref. 35388).
Adults are found inshore and shelf waters, close to bottom as well as in surface and mid-waters, pursuing shoals of clupeids and mugilids. They congregate inshore to spawn during spring and summer. Juveniles and sub-adults enter estuaries and coastal lagoons (Ref. 3593). Both adults and juveniles are migratory moving along shore or offshore-onshore in response to temperature change (Ref. 11025). Feed on fishes and swimming crustaceans.
