Alfonsino, Beryx splendens Lowe 1833

More Info


Distribution

Coral Sea, Queensland, around southern Australia, to off Rowley Shoals, Western Australia; also on the Lord Howe Rise and Norfolk Ridge in the Tasman Sea. Elsewhere, the species is worldwide between 62ºN and 42ºS; absent from the NE Pacific.

Alfonsinos aggregate over the outer continental shelf and slope, often around seamounts, ridges and rises in association with deep-sea coral habitats. They are benthopelagic during the day, and make forays above the bottom to feed at night on mesopelagic fishes and crustaceans. Larvae and juveniles are pelagic at depths of 50-200m.

Features

Dorsal fin III-IV, 12-15; Anal fin IV, 25-30; Caudal fin 19; Pectoral fin 15-19; Pelvic fin I, 9-13; Lateral line scales (to end of caudal fin) 69-82; Scales above lateral line 9.

Body oval, moderately deep, compressed, depth 33-40% SL (standard length), equal to or slightly more than head length. Head large, eye very large, diameter 40-42% HL; mouth reaching to below middle of eye.

Anal-fin origin below rear part of dorsal fin base. First dorsal-fin rays sometimes elongate in small specimens.

Colour

Head and body bright red above, becoming silvery-pink below; iris of eye and fins bright red.

Feeding

Often forms dense schools to feed on fishes, crustaceans and cephalopod molluscs.

Biology

The Alfonsino is an egg-layer (oviparous) and a serial spawner. The eggs are buoyant and hatch after 8 days. The larvae remain in the plankton for several months before settling on shallow seamounts. The species reportedly lives for more than 20 years.

Fisheries

Commercially important in many parts of its range, and taken with long-lines and in commercial trawls. A popular food fish around the world.

Etymology

The specific name is from the Latin splendens (= shining, glittering) presumably in reference to the bright silvery-reddish colour of this species.
