Rock Cale

Aplodactylus lophodon

Rock Cale (Aplodactylus lophodon) is a temperate reef fish of southeastern Australia and Tasmania, where it grazes on algae around rocky reefs and kelp beds. It is not a major target species and is more often encountered by divers or anglers fishing inshore structure.

Identification points

Deep, laterally compressed body with a steep forehead profile
Mottled brown to olive coloration that blends with weed-covered rock
Long dorsal fin and thick, blunt head with fleshy lips

Habitat

Shallow to moderate-depth rocky reefs, kelp forests, surge channels, and reef edges with abundant algae, usually close to broken bottom and reef structure.

Bait notes

If targeted, small baits of seaweed, mussel, or squid strips can take it, though it is not a common sportfish. Small reef jigs or lightly weighted bait rigs near algae-covered rock may also work.

Behavior

Primarily herbivorous, browsing on turf algae and larger seaweeds; it stays close to reef cover and can be cautious around heavy boat traffic and strong surge.

Caution

Handle carefully around rocky reef and surge zones; the species is not known for notable human safety or consumption hazards, but local size and bag limits may apply.

Fishing notes

Fish tight to rocky structure with light tackle and minimal weight; keep presentations natural and slow. Many captures are incidental while fishing for other reef species, so landing it cleanly requires care around rocks and weed.
