Shaughnessy's Nyacca Baitfish - Montana Fly Co

Montana Fly Co Shaughnessy’s Nyacca Baitfish When the bluewater predators are keyed on baitfish, nothing sells like the Nyacca. Developed by Baja legend James Shaughnessy (FlyFishMex / Beulah), this fly is built to trigger strikes from roosters, billfish, dorado, GTs, tuna—anywhere fish chase schooling bait. Key Features & Benefits Realistic baitfish profile — The fly’s layered, feather-tail construction gives subtle undulations and lifelike movement even on long slow strips. Fast to cast / easy handling — Materials are selected to shed water, reducing drag and allowing quick recovery on every cast. Versatile color & size options — Available in Olive/White, Tan/Cotton Candy, and “Holy Mackerel” versions. Built for big-game saltwater use — It’s one of the “go-to” flies for casting to billfish, and a proven pattern for roosterfish in Baja and inshore/nearshore predator work. Durable construction — Designed to hold up through repeated strikes, while maintaining the action that entices big fish. Use Cases / Angling Scenarios Cast to cruising roosterfish working bait in the shallows. Strip or “slow roll” the fly in deeper structure where billfish or tuna are feeding on dispersion. Fish it behind poppers or plugs as a “trailer” to mimic wounded baitfish. Drop back into cleaner water after heavy topwater work as a fallback baitfish imitation.
