More Info
Distribution |
Endemic to temperate waters of southern Australia, from Jervis Bay (New South Wales) to off Lancelin (Western Australia). The Bight Redfish is benthopelagic on deeper offshore reefs, rocky outcrops and pinnacles at depths of 11-260 metres (rarely below 200 m). The species is either solitary or occurs in pairs within caves and beneath ledges and overhangs. |
Features |
Dorsal fin VI, 12-13; Anal fin IV, 12-13; Caudal fin 19; Pectoral fin 13-14; Pelvic fin I, 7; Lateral line scales 36-39; Scales between dorsal-fin origin and lateral line 6-7. Body short, deep (approx. 50% SL), strongly compressed. Head large (approx. 40% SL), with coarsely serrated bony ridges on preopercle and opercle; eyes very large (36-40% HL); mouth large, oblique, reaching past centre of eye; teeth minute, broad band in upper jaw, narrow band in lower; operculum with serrated bony border. Scales of moderate size, distinctly ctenoid, covering body and in vertical patches anteriorly on opercle and lower part of preopercle; lateral line straight. Single dorsal fin of moderate length, positioned centrally on back with spines lengthening evenly posteriorly, first few soft rays progressively longer, subsequent rays decreasing abruptly posteriorly; anal fin similar to and opposite soft part of dorsal fin, ending slightly beyond posterior end of dorsal-fin base; caudal fin deeply forked. Pectoral fins long, pointed, upper rays longest. Pelvic fins pointed. |
Biology |
One individual caught off Albany, Western Australia, was found to be 84 years old based on a count of the annual growth rings on the otoliths. |
Fisheries |
A highly regarded table fish is fishes with hook and line over prominent ledges, rocky outcrops, pinnacles, and deeper reefs, usually in depths of 30-60m. For information on humanely killing Bight Redfish check out the ikijime website. The eating qualities of Bight Redfish is greatly improved by killing them immediately by iki jime, or by a firm knock to the head before placing them in an ice slurry. http://www.ikijime.com/fish/bight-redfish/ |
