Etymology: Merluccius: Latin, mar, maris = the sea + Latin, lucius = pike (Ref. 45335).
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
生態學
海洋 深海底的; 海洋洄游的 (Ref. 51243); 深度上下限 50 - 500 m (Ref. 1371). 深水域; 4°S - 14°S
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 / 年齡
Maturity: Lm 35.0 range ? - ? cm
Max length : 68.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 1371); 115.0 cm TL (female); common length : 50.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 1371); 最大年齡: 13 年 (Ref. 9722)
背棘 (總數) : 1; 背的軟條 (總數) : 45 - 54; 臀棘: 0; 臀鰭軟條: 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).
尾鰭邊緣通常凹曲。 色彩是銀色的背面, 銀色的微白色的在腹面上。 M. gayi gayi 與 M. gayi peruanus 不同藉由頭部的脊椎骨總數，鰓耙的總數與相對長度。 (參考文獻 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).
生存於水淺的大陸棚到大陸坡上層。 (參考文獻 1371) 有時發現自底部或在中層水域中.(參考文獻 1371) 在市場上銷售生鮮和冷凍以及製成魚漿.(參考文獻 1371)
