Etymology: Merluccius: Latin, mar, maris = the sea + Latin, lucius = pike (Ref. 45335).
; সামুদ্রিক সমুদতলে ভাসমান বেনথোপেলাজিক; মহাসাগরে বিচরনক্ষম (Ref. 51243); গভীরতার পরিসীমা 28 - 1000 m (Ref. 58489). Subtropical, preferred 9°C (Ref. 107945); 33°S - 59°S, 165°E - 66°W (Ref. 58452)
Circumglobal in the southern hemisphere (Ref. 7300). Two distinct groups. New Zealand population: Chatham Rise, Campbell Plateau and South Island northward to the East Cape. Patagonian population: Chiloé Island in the Pacific, southward around the southern tip of South America to the continental shelf to 59°S, and the slope north to 38°S in the Atlantic.

Max length : 155 cm SL পুরুষ/ লিঙ্গ অনিধর্ারিত ; (Ref. 58452); common length : 80.0 cm TL পুরুষ/ লিঙ্গ অনিধর্ারিত ; (Ref. 1371); সর্বোচ্চ উলি্ল্লখিত বয়স : 30 বৎসর (Ref. 9072)
পৃষ্ঠীয় কাঁটা (মোট ): 1; পৃষ্ঠীয় নরম পাখনা দন্ড (মোট ): 48-57; পায়ূ কাঁটা 0; পায়ূর নরম পাখনা্তুন্ড: 40 - 46; কশেরুকা : 53 - 58. Body more slender than other hakes. Pectoral fins long and slender, stripe reaching anal fin in young individuals but not in fish over 50 cm in SL. Gill rakers short and thick with blunt tips. Color is steel gray on back grading to silvery white ventrally.
Found at depths between 415 and 1000 m in New Zealand waters, and 62 to 800 m in South American waters. The Patagonian population feeds on southern blue whiting, whiptail, nototheniids and squids. The New Zealand population feeds mainly on fishes (especially gadoids), squids, euphausiids and benthic organisms. Adults probably migrate southward during the southern summer for feeding and return to the north in winter for spawning (Ref. 1371). Spawning takes place from August to September on the western coast of South Island, from September to November in the northern part of the Campbell Plateau, and between November and January on Chatham Rise (Ref. 58452). Utilized as food fish and fishmeal.
