More Info


Distribution

Recorded in Australia from about Noosa, Queensland, to Apollo Bay, Victoria, and northern Tasmania; also at Lord Howe Island in the Tasman Sea. Rock Blackfish are relatively rare in Victoria west of Wilsons Promontory. Elsewhere the species occurs in northern New Zealand.
Inhabits exposed rocky reefs in depths to 25 m, often in turbulent waters. Forms large schools under piers and jetties and around rocky outcrops, and often shelters in caves, under ledges and around boulders during the day. Juveniles prefer more sheltered habitats such as seagrass beds, tidepools, and sheltered reef areas.

Features

Dorsal fin XIII, 14; Anal fin III, 11-12; Caudal fin 17; Pectoral fin 19; Pelvic fin I, 5; Lateral line approx. 51-58.
Body moderately deep (approx. 42% SL), compressed, dorsal and ventral profiles evenly arched; caudal peduncle moderately shallow. Head small (approx. 27% SL), forehead slightly convex; eyes small (approx. 25% HL); mouth small, not reaching below eyes, maxillae concealed beneath respective preorbital bones; each jaw with single outer row of non overlapping, flattened, tricuspid teeth bordering broad band of minute teeth of similar shape.

Scales moderately small, ctenoid, covering body, most of cheeks, upper half of opercles and bases of dorsal and anal fins; lateral line continuous, parallel with upper profile of body.

Dorsal fin continuous with little demarcation between spinous and soft portions, base of spinous portion about 1.3 times as long as that of soft part, spines progressively longer posteriorly, soft rays markedly longer than spines, soft portion of dorsal rounded; anal fin similar to and opposite soft part of dorsal fin; caudal fin very large, broadly forked. Pectoral fins small, upper rays longest. Pelvic fins small, inserted below, and just behind pectoral fin bases.

Feeding

Omnivore - feeds on a rande of invertebrates and algae.

Fisheries

A popular angling fish in southern Queensland and New South Wales. Cunjuvoi, red bait crabs and the sea cabbage Ulva are often used as bait. The flesh is of good quality when eaten fresh.
