Rough Leatherjacket

Scobinichthys granulatus

Rough Leatherjacket is a small tropical to subtropical filefish-like marine species in Australasian waters, though published fishery information is limited. It is usually encountered over reefs, rubble, and seagrass, and is not a major angling target.

Identification points

Rough, granular skin texture on the body and head
Deep, laterally compressed filefish-like body with a small mouth
Long first dorsal spine and mottled brown to olive coloration

Habitat

Shallow coastal marine habitats, especially reefs, rubble slopes, seagrass beds, and sheltered lagoons over sand or coral substrate.

Bait notes

Not a common sport species; if caught, small pieces of shrimp, squid, worm, or tiny reef baits on light tackle may take bites. Small soft plastics or micro jigs worked near bottom can also work.

Behavior

Benthic and cautious, picking at small invertebrates, algae, and epifauna around structure; often stays close to bottom cover and can be finicky when hooked.

Caution

Spines and rough skin can cause minor cuts; handle carefully. Check local rules and release any bycatch promptly, as it is not typically a regulated target species.

Fishing notes

Use light fluorocarbon leaders, small hooks, and minimal weight; present baits close to cover and keep retrieves slow and low. Because it is not a primary gamefish, many anglers encounter it while fishing reefs or estuaries for other species.
