Wikipedia
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 UK Marine Conservation Society has categorized orange roughy as "vulnerable to exploitation". It is found in , deep (bathypelagic, ) 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, living for up to 149 years. It is important to commercial deep- trawl fisheries. The fish is a bright, brick-red color; fading to a yellowish-orange after death.
Like other slimeheads, orange roughy is slow-growing and late to mature, resulting in a very low resilience which makes them extremely susceptible to overfishing. Many stocks (especially those off New Zealand and Australia, which were first exploited in the late 1970s) became severely depleted within 3–20 years, but several have subsequently recovered (see Fisheries below).
