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
البيئة
بحري; مياه مخلوطة قاعية التغذية و المعيشة; محيطية (Ref. 51243); نطاق العمق 15 - 300 m (Ref. 2683). Subtropical; 65°N - 6°S, 23°W - 36°E
Eastern Atlantic: Norway to Gibraltar and Congo, including the Mediterranean and the Black Sea. Migrated to the Red Sea via the Suez Canal.
Length at first maturity / الحجم / وزن / العمر
Maturity: Lm ?, range 80 - ? cm
Max length : 230 cm TL ذكر/ مختلط الجنس; (Ref. 5377); common length : 150 cm TL ذكر/ مختلط الجنس; (Ref. 3593); أعلا وزن تم نشرة: 103.0 kg (Ref. 11036)
الأشواك الظهرية (المجموع): 10 - 11; الأشعة الظهرية الناعمة (المجموع): 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.
