Panamic Sergeant Major
Abudefduf troschelii
Panamic Sergeant Major is a striped damselfish common on rocky reefs and tidepools along the eastern tropical Pacific. It is a bold, schooling omnivore that readily pecks at small benthic foods and is often very approachable by divers.
Identification points
- Bright blue-green body with 4–5 dark vertical bars
- Deep, laterally compressed damselfish body with a small mouth
- Yellowish to pale fins, often with a dark spot near the base of the pectoral fin
Habitat
Shallow rocky reefs, surge channels, tide pools, jetties, and harbor pilings in warm coastal waters; usually from the intertidal zone to a few meters deep.
Bait notes
Rarely targeted as a game fish, but will take tiny hooks baited with shrimp pieces, chopped squid, worms, or bread crumbs; small gold spoons, micro-jigs, and bits of soft plastic can also draw strikes.
Behavior
Forms loose schools and feeds by picking plankton, algae, and tiny benthic invertebrates from the water column and hard surfaces. Adults are territorial around nesting sites and can be aggressive toward intruders.
Caution
Sharp reef habitat can cause cuts; handle carefully because the fish is small and easily stressed. In many areas it is not a regular food species, so check local rules and avoid relying on it for consumption.
Fishing notes
Use very light tackle and small hooks around rocky shorelines, pilings, and tide pools. Fish near structure on a steady drift or slow retrieve; they usually respond best when bait is presented close to the surface or just above the bottom.
