The orange roughy or red roughy (Hoplostethus atlanticus) is a relatively large deep-sea fish belonging to the slimehead family (Trachichthyidae). It is found in cold (3–9°C), deep (bathypelagic, ca. 180–1,809 m) waters of the Western Atlantic (off northern Nova Scotia), Eastern Atlantic (from Iceland to Morocco; and from Walvis Bay, Namibia to off Durban, South Africa), Indo-Pacific (off New Zealand and Australia), and in the Eastern Pacific off Chile. The orange roughy is notable for its great age—a recorded (but hotly disputed) maximum of 149 years—and great importance to commercial deep trawl fishery. Actually a bright brick red in life, the orange roughy fades to a yellowish orange after death.
