Issue
Provisionally valid species. When recognized, mainly considered as a subspecies of Merluccius gayi (Guichenot, 1848). Still more studies are needed to characterize it (March 2021).

Short description
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 1; Radios blandos dorsales (total) : 45 - 54; Espinas anales: 0; Radios blandos anales: 36 - 42. 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): elongated.
Occurs from the shallow continental shelf to the upper continental slope (Ref. 1371). Sometimes found off the bottom or in midwater (Ref. 1371). Marketed fresh and frozen and also used for fishmeal (Ref. 1371).
