Actinopterygii (ray-finned fishes) |
Alternative Name: |
Splendid alfonsino |
Max size: |
70.0 cm TL (male/unsexed; Ref. 30573); max. reported age: 23 years |
Environment: |
Benthopelagic; marine ; depth range 25 - 1300 m |
Climate: |
Subtropical; 65°N - 43°S, 180°W - 180°E |
Importance: |
Fisheries: commercial |
Resilience: |
Low, minimum population doubling time 4.5 - 14 years (K=0.10-0.18; tm=5-7.5; tmax=23) |
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). |

Dorsal spines (total): 4; Dorsal soft rays (total): 13-16; Anal spines: 4; Anal soft rays: 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). |
