(Perch-likes) > Carangidae
(Jacks and pompanos) > Caranginae
Etymology: Trachurus: Greek, trachys, -eia, -ys = rough + Greek, oura = tail (Ref. 45335). More on author: Linnaeus.
Environment: milieu / climate zone / depth range / distribution range
; marinhas; oceanódromo (Ref. 51243); intervalo de profundidade 0 - 1050 m (Ref. 54256), usually 100 - 200 m (Ref. 54256). Subtropical; 67°N - 38°S, 26°W - 42°E
Mediterranean Sea and eastern Atlantic: Norway to South Africa, round the coast to Maputo.
Length at first maturity / Tamanho / Peso / Idade
Maturity: Lm 23.9, range 21 - 30 cm
Max length : 70.0 cm TL macho/indeterminado; (Ref. 3197); common length : 22.0 cm FL macho/indeterminado; (Ref. 3397); peso máx. Publicado: 2.0 kg (Ref. 27584)
Espinhos dorsais (total): 9; Raios dorsais moles (total): 30-36; Espinhos anais 3; Raios anais moles: 24 - 32. Bluish green, grey or black above, silvery white below; opercle with black spot (Ref. 3197). Lateral scales tall and keeled. Gill cover with a distinct black spot. First dorsal fin tall (Ref. 35388).
Adults form large schools in coastal areas with sandy substrate. They feed on fish, crustaceans, and cephalopods. Are batch spawners (Ref. 51846). Females lay 140,000 eggs, which hatch into 5mm long larvae (Ref. 35388). Eggs are pelagic (Ref. 4233). Utilized fresh, smoked, canned and frozen; can be fried, broiled and baked (Ref. 9988). Divided into two stocks: West stock and North Sea stock. West stock spawns in a belt from the Biscay to Ireland in early spring, migrates north and eastwards to southern Norway and northern North Sea. North Sea stock spawns in the southern North Sea in summer, migrates to central North Sea, Skagerrak and Kattegat.
