More on author: Ginsburg.
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).
Environment: milieu / climate zone / depth range / distribution range
生态学

Southeast Pacific: off the coast of Peru, from Paita southward to Huarmey.
東南太平洋: 外海的祕魯的海岸,從 Paita 向南至 Huarmey 。
Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 35.0 range ? - ? cm
Max length : 68.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 1371); 115.0 cm TL (female); common length : 50.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 1371); 最大年龄: 13 年 (Ref. 9722)

尾鳍边缘通常凹曲。 色彩是银色的背面, 银色的微白色的在腹面上。 M. gayi gayi 与 M. gayi peruanus 不同藉由头部的脊椎骨总数，鳃耙的总数与相对长度。 (参考文献 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).
生存于水浅的大陆架到大陆坡上层。 (参考文献 1371) 有时发现自底部或在中层水域中.(参考文献 1371) 在市场上销售生鲜和冷冻以及制成鱼浆.(参考文献 1371)
