Merlucciidae (Merluccid hakes)
Etymology: Merluccius: Latin, mar, maris = the sea + Latin, lucius = pike (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Ecologia
marinhas batidemersal; não migratória; intervalo de profundidade 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).
Comprimento de primeira maturação / Tamanho / Peso / Idade
Maturity: Lm 47.8 range ? - ? cm
Max length : 115 cm TL macho/indeterminado; (Ref. 27121); common length : 60.0 cm SL macho/indeterminado; (Ref. 1371)
Espinhos dorsais (total) : 1; Raios dorsais (total) : 42 - 50; Espinhos anais: 0; Raios anais : 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.
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).
