A different species/subspecies is recognized on the Peruvian coasts Merluccius peruanus Ginsburg, 1954, that is recognized in FishBase as a provisionally valid species. More studies are needed to clearly differentiate it (March 2021).
Entorno: milieu / zona climática / rango de profundidad / gama de distribución
Ecología
marino batidemersal; oceanodromo; rango de profundidad 50 - 500 m (Ref. 1371). Deep-water; 5°S - 46°S, 81°W - 69°E (Ref. 54583)

Longitud en la primera madurez / Tamaño / Peso / Edad
Madurez: Lm ?, range 32 - ? cm
Max length : 87.0 cm TL macho / no sexado; (Ref. 1371); common length : 50.0 cm TL macho / no sexado; (Ref. 1371)
Espinas dorsales (total) : 1; Radios blandos dorsales (total) : 45 - 54; Espinas anales: 0; Radios blandos anales: 36 - 42; Vértebra: 49 - 53. Caudal fin margin usually concave. Color is silvery on back, silvery whitish on belly. M. gayi gayi and M. gayi peruanus differ by the total number of vertebrae, total number of gill rakers and relative length of head (Ref. 1371).
Body shape (shape guide): fusiform / normal; Cross section: oval.
Occurs from the shallow continental shelf to the upper continental slope (Ref. 1371). Sometimes found off the bottom or in midwater (Ref. 1371). Migrates vertically to midwater at night to feed on fishes, squids and euphausiids (Ref. 27363). Moves to southern coastal areas in summer and migrates to northern deeper waters (200-500 m depth) in winter and spring (Ref. 27363). Spawning occurs at the end of the winter and during the southern spring (Ref. 58452). Marketed fresh and frozen (Ref. 1371) and eaten steamed, fried, boiled and microwaved (Ref. 9988). Also utilized as fishmeal (Ref. 1371).
