Summary:
A dusky greenish- to yellowish-brown rockcod covered in small dark blue-centred spots, sometimes with a faint dark band from the snout tip to the eye, and dusky to blue fins with pale blue margins. Juveniles have a banded pattern.
The Eastern Wirrah is also called the "Old Boot" due to its unpleasant taste.

Eastern Wirrah, Acanthistius ocellatus (Günther 1859)

More Info


Distribution

Southern Queensland to Western Port, Victoria and northern Tasmania; also the Lord Howe Province in the Tasman Sea. The Eastern Wirrah is common in New South Wales waters, but is rarely seen on the south coast.

Inhabits shallow estuaries, tidepools, and deeper offshore reefs to a depth of 100 m. Individuals shelter in caves, crevices and holes when approached.

Features

Dorsal fin  XIII, 15–16; Anal fin III, 8–9; Caudal fin 17; Pectoral fin 19–21; Pelvic fin I, 5; Lateral line scales 58–67.

Body depth 33–40% SL; head length 39–42% SL; eye diameter 7–8% HL.

Colour

Dusky yellow with many dark, usually blue-centred spots covering head and body, slightly smaller on head; sometimes with faint dark band from tip of snout to eye; fins dusky to blue, with pale blue margins.

Fisheries

Although frequently caught on hook and line, the flesh is of poor eating quality.

Remarks

Relatively common on deeper reefs in New South Wales, and often taken on hook and line by recreational fishers.

Etymology

The specific name is from the Latin ocellatus (= with little eyes), in reference to the dark blue-centred spots on the head and body.
