Merlucciidae (Merluccid hakes)
Etymology: Merluccius: Latin, mar, maris = the sea + Latin, lucius = pike (Ref. 45335).
Eponymy: Claude Gay (1800–1873) was a French botanist. [...] (Ref. 128868), visit book page.
More on author: Guichenot.
Issue
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).
Environment: milieu / climate zone / depth range / distribution range
生态学
海洋 深海底的; 海洋洄游的; 深度上下限 50 - 500 m (Ref. 1371). 深水域; 5°S - 46°S, 81°W - 69°E (Ref. 54583)
Southeast Pacific: off the coast of Chile from Arica to Chiloé Island.
東南太平洋: 來自阿利卡到 Chiloe 島的外海的智利的海岸。
Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm ?, range 32 - ? cm
Max length : 87.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 1371); common length : 50.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 1371)
背棘 (总数) : 1; 背的软条 (总数) : 45 - 54; 臀棘: 0; 臀鳍软条: 36 - 42; 脊椎骨: 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).
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). 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).
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) 垂直地对中层水域回游在晚上觅食鱼，乌贼与磷虾.(参考文献 27363) 在夏天移动到南方的沿岸区域而且在冬天与春天回游到北方的较深的水域 (200-500 公尺深) 。 (参考文献 27363) 在市场上销售生鲜和冷冻 (参考文献 1371) 而且清蒸了, 油炸了, 煮沸了而且微波了.(参考文献 9988) 也利用了制成鱼粉。 (参考文献 1371)
