Gafftopsail Pompano
Trachinotus rhodopus
A small yellow-finned Pacific pompano of sandy surf beaches — from Baja and the Sea of Cortez down the Mexican mainland coast, taken on sand crabs, shrimp and small jigs in the wash.
Seasons · Peak
Identifying features
- Deep diamond-shaped silver body with yellow fins, especially the forked tail
- Dorsal fin long and sail-like at the front — the tall lobe gives the 'gafftopsail' name
- Dark vertical bars on juveniles that fade with age
- Small mouth and blunt forehead, like other pompanos
- Look-alike: Florida pompano is an Atlantic species; this yellow-finned fish is Pacific only
Habits
- Schools over sand in the surf, tipping to pick small invertebrates from the wash
- Feeds on small invertebrates and small fishes
- Most active in warm water and in the morning wash
- Often mixes with other small jacks and pompanos along the same beach
Distribution
Where to find them
- Surf wash and troughs on East Cape and La Paz sand beaches
- Sand edges next to reefs and rocky points
- Shallow bays around Mazatlán and Bahía de Banderas

How to catch them
Surf fishing with sand crabs Shore

Key tip: Retrieve fast with pauses while walking the moving water's edge.
Beach-walking fly fishing Shore

Recommended gear for this species
Rod · Best value
9' medium-heavy surf spinning rod
≈ US$110-170
Casts plugs and bait past the breakers and handles stripers, drum and bluefish in the wash.
Reel · Best value
5000 size sealed spinning reel
≈ US$120-180
Salt spray and dunkings kill cheap reels — a sealed body and 30 lb braid capacity are the surf standard.
Terminal · Budget
Topwater plugs, soft-plastic jigs and fish-finder rigs
≈ US$25-40
Plugs for blitzes, jigs for the trough, bait on a fish-finder rig when they won't chase — the inshore trio.
