Western Atlantic: Gulf of Maine (Ref. 4784) [in error according to Moore (Fishes of the Gulf of Maine, in press), should be off northern Nova Scotia]. Eastern Atlantic: Iceland to Morocco; Walvis Bay, Namibia to off Durban, South Africa. Indo-Pacific: south-central Indian Ocean and New Zealand. Eastern Pacific: Chile (Ref. 27363). Several stocks may exist as suggested by distinct spawning sites and seasons.

Sinh học     Tự điển (thí dụ epibenthic)

Inhabits deep, cold waters over steep continental slopes, ocean ridges and sea-mounts. Shallow range of usual occurrence from Ref. 27121. Appears to be dispersed over both rough bottoms and steep, rough grounds where it feeds on crustaceans and fish. In New Zealand, the main prey include mesopelagic and benthopelagic prawns, fish, and squid, with other organisms such as mysids, amphipods and euphausiids occasionally being important (Ref. 9072). Juveniles feed mainly on crustaceans (Ref. 27075, 27076). Grows very slowly and is one of the longest lived fish species known. Based on parasite and trace-element analyses, orange roughy is a sedentary species with little movement between fish-management zones (Ref. 27089). Little is known of the larvae and juveniles which are probably confined to deep water (Ref. 27088). The fishery targets sporadically formed dense spawning and non-spawning aggregations. Marketed fresh and frozen; eaten steamed, fried, microwaved and baked (Ref. 9988). Because of severe overfishing the species has been listed as threatened by the Australian Government in 2006.

Life cycle and mating behavior Maturities | Sự tái sinh sản | Spawnings | Egg(s) | Fecundities | Ấu trùng

Orange roughy are synchronous annual spawners (Ref. 7030). They form dense spawning aggregations over sea hills and slopes. Eggs and sperms are shed into the water at the same time. Individual males appear to spawn over a 1-2 week period and females spawn for up to 1 week. Little is known of the larvae and juveniles.
