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).

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).
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).
