Indo-Pacific Sergeant Major

Abudefduf vaigiensis

Indo-Pacific Sergeant Major is a bold, reef-associated damselfish common on shallow tropical coasts and around harbors, jetties, and coral heads. It feeds opportunistically on plankton, algae, and small benthic invertebrates and is often curious around divers and anglers.

识别要点

Five bold dark vertical bars on a yellow to yellow-green body
Blue to dusky spots or streaks on the upper body and fins
Deep, laterally compressed damselfish shape with a small terminal mouth

栖息地

Shallow Indo-Pacific coral reefs, lagoon edges, surge channels, harbor pilings, jetties, and rocky breakwaters; usually in very warm, clear inshore saltwater, often near structure and above reef flats.

饵料备注

Small hooks with tiny pieces of shrimp, squid, fish flesh, bread, or dough bait can work; very small soft plastics, micro jigs, and bits of fly tied to imitate plankton are also effective. Often bites readily but is small.

行为

Schooling and highly territorial around hard structure; picks at plankton and algae in the water column and on surfaces, with quick darting strikes and persistent curiosity. It often stays midwater to near-surface over reefs.

注意事项

Sharp reef structure can cut line and hands; handle with care around spines and abrasive coral. Like many reef fish, local consumption advisories may apply in some tropical areas; check for ciguatera risk where the species is eaten.

钓法备注

Use light tackle and small terminal gear near reef edges, docks, or breakwaters. Drifting tiny baits in the current or slow-retrieving micro lures is best; expect short strikes and frequent pecks rather than hard runs.
