Eyestripe Surgeonfish
Acanthurus dussumieri
Eyestripe Surgeonfish is a reef-dwelling surgeonfish of the Indo-Pacific, known for its fine yellow eye-stripe and grazing lifestyle. It is not a common sport target, but it can be taken incidentally on light tackle around coral and rubble reefs.

Identification points
- Distinct narrow yellow-orange stripe running through the eye on a brownish body
- Tall, laterally compressed surgeonfish body with a pale to dark tail base and sharp tail spines
- Fine pale spotting or subtle lines on the head and body, with a small mouth for grazing
Habitat
Lagoon and outer-reef slopes, coral-rich drop-offs, and rubble areas from shallow water to deeper reef edges; usually near current-swept zones where algal growth is available.
Bait notes
Rarely targeted by anglers. If local rules allow and capture is intended, very small algae strips, bread bits, or tiny crustacean pieces on fine hooks may tempt it; small reef flies and nymph-like lures can also draw strikes.
Behavior
Primarily a diurnal grazer that browses filamentous algae and detritus, often in small groups. It stays close to reef structure and can be wary, moving quickly and using its scalpel-like tail spines for defense.
Caution
Sharp caudal spines can inflict deep cuts; handle only with caution. In some regions reef fish consumption may carry ciguatera risk, so local advisories matter. Check local rules because reef herbivores may be protected or discourage- take in some areas.
Fishing notes
Use ultralight tackle, tiny hooks, and minimal terminal gear around reef edges; present baits naturally and quietly near feeding fish. Handle carefully with a landing net or wet hands, as surgeonfish can thrash and slash with the caudal spines.
