Fly fishing for Twaite Shad (Alosa fallax) can be an exciting and rewarding experience, as these fish are strong fighters and often take flies aggressively during their spawning runs. Here’s a comprehensive guide to help you target them effectively:

1. Understanding Twaite Shad

Habitat: Twaite shad are anadromous (migrate from sea to freshwater to spawn) and are found in estuaries and lower river systems in Europe (e.g., UK, France, Spain).
Season: Best targeted in spring and early summer (April–June) when they enter rivers to spawn.
Behavior: They feed on small baitfish, crustaceans, and insects, often in fast-moving water.

2. Fly Fishing Gear

Rod & Reel

Rod: A 7–9 wt fly rod (fast action) to handle larger flies and strong currents.
Reel: A sturdy reel with a smooth drag to manage hard runs.
Line: A floating or intermediate sinking line, depending on water depth and flow.

Leader & Tippet

Leader: 7.5–9 ft tapered leader (0X–2X).
Tippet: 8–12 lb fluorocarbon for abrasion resistance.

3. Best Flies for Twaite Shad

Shad are aggressive and often strike out of instinct rather than hunger. Use small, flashy streamers that mimic baitfish or shrimp.
Recommended Fly Patterns

Clouser Minnow (white/chartreuse, size 6–10)
Deceiver (silver/blue, size 6–8)
Shad Dart (red/white, size 8–10)
Sparkle Shrimp (pink/orange, size 10–12)
Zonker (pearl/silver, size 6–8)

Retrieve Technique

Fast strips to trigger aggressive strikes.
Vary retrieve speed—shad often chase and hit on the pause.

4. Where to Fish

Estuaries & Tidal Rivers: Look for current seams, eddies, and drop-offs where shad congregate.
Upstream of Obstacles: Fish below weirs, bridges, or rapids where shad pause.
Shallow Runs: Target 1–3 ft deep water with moderate flow.

5. Best Times & Conditions

Tide & Light: Fish rising tides and low-light periods (dawn/dusk).
Water Clarity: Slightly stained water is ideal (avoid heavy floods).
Temperature: Active in 12–18°C (54–64°F) water.

6. Fighting & Handling

Strike Quickly: Shad have soft mouths—avoid over-striking.
Use a Net: Rubberized nets prevent scale damage.
Handle with Care: Shad are fragile—minimize handling and release quickly.

7. Conservation

Catch & Release: Many populations are declining; use barbless hooks.
Avoid Spawning Fish: If you see shad actively spawning, move to another spot.

Final Tips

Scout for Jumping Fish: Shad often leap or roll at the surface.
Stay Mobile: Cover water until you find active fish.
Try Bright Colors: Pink, orange, and chartreuse can be deadly.

Twaite shad fishing is fast-paced and visual—enjoy the explosive takes! Tight lines! 🎣
