Etymology: Beryx: Greek, beryx or berys = a name of a fish. Cuvier & Valenciennes (1829:221) precise that the name was used by Gesner from Varinus, but with no indication whatsoever helping identifying any species. After D'Arcy Wentworth Thompson (A glossary of Greek fishes, 1947), the name actually seems to come originally from Hesychius, but perhaps the name was not originally a fish name. Thompson compares it to meryx (ruminant), applied on skaros (Scarus), so it may have been applied on a parrot fish referring to its browsing/grazing behavior described by Aristoteles and followers..  More on author: Lowe.

; seewasser benthopelagisch; tiefenbereich 25 - 1300 m (Ref. 9833), usually 400 - 600 m (Ref. 27121).   Subtropical; 45°N - 43°S, 180°W - 180°E

Verbreitung Länder | FAO Gebiete | Ecosystems | Vorkommen | Point map | Einführungen | Faunafri

Circumglobal, excluding the northeast Pacific and Mediterranean Sea (Ref. 9833). Western Atlantic: Gulf of Maine to the Gulf of Mexico (Ref. 6743). Eastern Atlantic: off southwestern Europe and the Canary Islands (Ref. 7413) to South Africa (Ref. 4179). Indo-Pacific: East Africa (including Saya de Malha Bank, Ref. 33390) to Japan, Hawaii, Australia, and New Zealand (Ref. 5755). The limited number of records in the western Pacific is doubtless the result of limited fishing effort below 200 m (Ref. 9833). Eastern Pacific: Chile (Ref. 27363).

Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt): 4; Rückenflossenweichstrahlen (insgesamt): 13-16; Afterflossenstacheln 4; Afterflossenweichstrahlen: 26 - 30. First infraorbital bone with a spine projecting laterally on anterior end. Lateral line extends to caudal fin. A fleshy disk on inner face of exposed area of scale. In young fishes, the 2nd dorsal ray is elongate (Ref. 559). Ref. 27363 notes pectoral fins with one spine and 17 soft rays (Ref. 27363).

Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Adults inhabit the outer shelf (180 m) and slope to at least 1,300 m depth, probably moving further from the bottom at night; often found over seamounts (Ref. 9833) and underwater ridges (Ref. 33648). Juveniles pelagic (Ref. 9072). Feed mainly on fish, crustaceans and cephalopods (Ref. 33648). Oviparous, spawn in batches (Ref. 30291). Eggs and larvae are pelagic (Ref. 30291). Marketed frozen and eaten steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988).

Life cycle and mating behavior Geschlechtsreife | Fortpflanzung | Ablaichen | Eier | Fecundity | Larven

Spawning occurs about 10 to 12 times at intervals of about 4 days during the breeding season (Ref. 58433).
