Environment: milieu / climate zone / depth range / distribution range
البيئة
بحري قاعية التغذية و المعيشة; نطاق العمق 0 - 200 m (Ref. 3688), usually 15 - 50 m (Ref. 54220). Subtropical; 56°N - 12°N, 23°W - 42°E (Ref. 54220)
Eastern Atlantic: British Isles to Cape Blanc, Mauritania; (exceptionally further south) Senegal and around the Canary Islands and Madeira. Common south of 40°N (Spain, North Africa) in the Mediterranean (Ref. 4781).
Length at first maturity / الحجم / وزن / العمر
Maturity: Lm 34.6 range ? - ? cm
Max length : 100.0 cm TL ذكر/ مختلط الجنس; (Ref. 3397); common length : 50.0 cm TL ذكر/ مختلط الجنس; (Ref. 3688); أعلا وزن تم نشرة: 14.3 kg (Ref. 40637)
الأشواك الظهرية (المجموع): 11; الأشعة الظهرية الناعمة (المجموع): 11-12; شوكة شرجية 3; أشعه شرجية لينه: 7 - 9. Body oval and compressed. Canine teeth, with 4 to 6 anterior teeth very developed in each jaw.
Inhabit hard bottoms (rock or rubble) down to 200 m depth. Usually found in shallow water less than 50 m deep (Ref. 9987). Adults solitary; young gregarious (Ref. 12482). Young fish caught with traps. Feed on fish, mollusks and cephalopods. Important food fish. Marketed fresh or frozen (Ref. 9987). Some attempts to culture this species have been successful. Due to low market supply, the potential for selling these fish from aquaculture operations seems to be good (Ref. 9987). A spear-fisherman cites a specimen caught in Greece (Corfu) with an overnight bottom-line about 1.60 m and 42 kg (Ref. 48271), but the identification cannot be verified.
Life cycle and mating behavior
النضج | التكاثر | وضع البيض | بيض | الخصوبة | Larvae
Gonochoric, but some specimens are hermaphroditic. Species of separated sexes (although some individuals may be hermaphrodite in young stages). In the Mediterranean, reproduction takes place between March and May, in areas near the coast. Embryo development lasts about 3 days at 17°C.
