Crayfish Fly Patterns for Trout & Smallmouth Bass

If you want to target the largest fish in the river, you need to mimic what they eat most. Crayfish represent a massive, protein-packed food source for both smallmouth bass and stream trout. When baitfish fail and hatches are sparse, a properly presented crayfish fly pattern is often the key to triggering violent, aggressive strikes.

At Murray’s, our crayfish collection is engineered to replicate natural crustacean behavior. Unlike generic flies that ride too high in the water column, our patterns are designed to sink quickly and mimic the backwards, darting escape motion of a real crayfish. Whether you are swinging them through deep pools or dead-drifting them through rocky runs, these flies stay in the strike zone longer.

Match the Hatch: Choosing the Right Size & Presentation

To maximize your hookup rates, matching the local forage and perfecting your drift is essential:

• For Smallmouth Bass: We highly recommend opting for Size 6 crayfish patterns. This larger profile mimics mature river crayfish and provides the substantial meal that trophy smallmouth can't resist.

• For Stream Trout: When targeting trout on freestone or stocked streams, downsize to a Size 10 pattern. This smaller footprint perfectly replicates juvenile crayfish, a staple diet for resident and stocked trout alike.

• The Secret is in the Weight: To fish a crayfish fly effectively, you must get down and dirty. Pay close attention to your rigging and use the exact amount of weight needed to tick your fly naturally across the gravel bottom. If you aren't occasionally feeling the rocks, you aren't deep enough.
