Splendid alfonsino (Beryx splendens) fish species information

Scientific Name
Beryx splendens

Common Name
Splendid alfonsino

Biology
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).

Distribution

Region

Circumglobal, excluding the northeast Pacific and Mediterranean Sea (Ref. 9833). Western Atlantic

Distribution

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).
