Blackspot Boarfish, Zanclistius elevatus (Ramsay & Ogilby 1888)

More Info


Distribution

Found in southern Australia from Cape Moreton, southern Queensland, to just south of Dirk Hartog Island, Western Australia, and around Tasmania. Also at Lord Howe Island in the Tasman Sea. Elsewhere, the Blackspot Boarfish occurs in New Zealand waters north of about 41°S. 
The species is most often taken at depths of just less than 100 m, but it has been recorded to 540 m. It has a rather patchy distribution and is relatively common in some areas.

Features

Dorsal fin V-VIII, 25-29; Anal fin III, 12-17; Caudal fin 16-18; Pectoral fin 15-17; Pelvic fin I, 5; Lateral line scales 55-65.

Body deep (55-67% SL); sides strongly compressed and flat; dorsal profile broadly rounded. Head of moderate size (32-43% SL), predominantly covered with exposed, rough, striated bones; eyes large; snout lightly built, somewhat elongate, dorsal profile deeply concave; mouth small, nearly horizontal; teeth of both jaws short, conical, set in broad bands anteriorly, bands narrowing along sides; vomer toothless; older specimens developing bony knob on nape. 

Scales moderately small, ctenoid, covering body and head, but absent from opercular bones; lateral line strongly arched, following dorsal profile of body. 

Dorsal fin continuous, spines increasing in length posteriorly, anterior soft dorsal rays much longer than posteriormost dorsal spine, sometimes extending past caudal fin, posterior edge of dorsal fin concave; anal fin with short base, posterior margin straight, nearly vertical, spines large and strong; caudal fin slightly emarginate. Pectoral fins elongate, upper rays much longer than lower. Pelvic fins large, spine strong. (Hardy 1994)

Colour

Pale grey to pale yellowish-green, with darker, oblique broad bands on the body beneath the dorsal fin; prominent dark spot posteriorly on dorsal fin.

Fisheries

Taken as bycatch in demersal trawl fisheries. The flesh is considered to be of high quality.
