Etymology: Merluccius: Latin, mar, maris = the sea + Latin, lucius = pike (Ref. 45335).
Entorno: milieu / zona climática / rango de profundidad / gama de distribución
Ecología
marino batidemersal; no migratorio; rango de profundidad 200 - 1000 m (Ref. 6605), usually 400 - ? m (Ref. 58452). Deep-water; 17°S - 38°S, 10°E - 48°E (Ref. 58452)
Southeast Atlantic: Cape Frio, Namibia south to the Agulhas Bank and east to East London in South Africa. Western Indian Ocean: Madagascar Ridge (33°S,44°E).
Longitud en la primera madurez / Tamaño / Peso / Edad
Madurez: Lm 47.8 range ? - ? cm
Max length : 115 cm TL macho / no sexado; (Ref. 27121); common length : 60.0 cm SL macho / no sexado; (Ref. 1371)
Espinas dorsales (total) : 1; Radios blandos dorsales (total) : 42 - 50; Espinas anales: 0; Radios blandos anales: 38 - 41. Body more slender than other hakes. Head large, about 25 to 30% of SL. Gill rakers short and thick with blunt tips. Pectoral fin tips reaching to level of anal fin origin. Color is steel gray on back, grading to silvery white ventrally.
Body shape (shape guide): elongated; Cross section: oval.
Found near the bottom. Feeds on fishes, mysids, euphausiids and squids. Young feed mainly on euphausiids, but the diet becomes polyphagous with growth. Cannibalism has been observed in larger individuals (Ref. 9583).
