The striped beakfish (Oplegnathus fasciatus), also known as the barred knifejaw, is a species of marine ray-finned fish, a knifejaw from the family Oplegnathidae. It is native to the northwestern Pacific Ocean, though a smattering of records exist from other localities in the eastern Pacific such as Hawaii and Chile. It is an inhabitant of rocky reefs and occurs at depths from 1 to 10 m (3 to 33 ft). Juvenile members of this species can be found with patches of drifting seaweed. This species can reach a total length of 80 cm (31 in), with the greatest recorded weight for this species of 6.4 kg (14 lb). The color pattern consists of light and dark vertical bars from which it derives its name. It has been recorded as feeding on hard-shelled invertebrates such as crustaceans and molluscs. It is a commercially important species and is also farmed. It is also sought after as a game fish.[1]
Five striped beakfish, of which one remains in captivity, endured more than 2 years in the partially submerged hull of the Japanese boat Sai-shou-maru.[2][3]
