The orange roughy, re roughy, or deep sea perch, Hoplostethus atlanticus, is a relatively large deep-sea fish belonging to the slimehead family (Trachichthyidae). This fish is categorized as vulnerable to exploitation by the Marine Conservation Society. It is found in cold (3 to 9 °C), deep (bathypelagic, 180 to 1,800 m) waters of the western Pacific Ocean, 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 (disputed by commercial fishers but supported by scientists) maximum of 149 years — and importance to commercial deep trawl fishery. Actually a bright brick red in life, the orange roughy fades to a yellowish orange after death.
