The orange roughy, red roughy, slimehead or deep sea perch, Hoplostethus atlanticus, is a relatively large deep-sea fish belonging to the slimehead family (Trachichthyidae). The Marine Conservation Society has categorized orange roughy as vulnerable to exploitation. It is found in 3 to 9 °C (37 to 48 °F) deep (bathypelagic, 180 to 1,800 metres (590 to 5,900 ft) waters of the Western Pacific Ocean, eastern Atlantic Ocean (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 extraordinary lifespan, with lifespans up to 149 years determined by scientific methods. It is important to commercial deep trawl fisheries. The fish is actually a bright, brick red color; however, the orange roughy fades to a yellowish orange after death.
Like other slimeheads, the orange roughy is slow-growing and late to mature, resulting in a very low resilience. They are extremely susceptible to overfishing because of this, and many stocks (especially those off New Zealand and Australia, which were first exploited in the late 1970s) have already crashed; recently discovered substitute stocks are rapidly dwindling. The flesh is firm with a mild flavour; it is sold skinned and filleted, fresh or frozen.

Famous quotes containing the word orange:
“I’d take the bus downtown with my mother, and the big thing was to sit at the counter and get an orange drink and a tuna sandwich on toast. I thought I was living large!... When I was at the Ritz with the publisher a few months ago, I did think, “Oh my God, I’m in the Ritz tearoom.” ... The person who was so happy to sit at the Woolworths counter is now sitting at the Ritz, listening to the harp, and wondering what tea to order.... [ellipsis in source] Am I awake?”
