Twaite Shad
The twaite shad is an anadromous herring-family fish that once ran Dutch rivers in numbers but has declined sharply.
Small numbers still appear in the lower Rhine and Meuse during spring spawning runs, and the species is monitored closely as a conservation indicator.
Catching one in the Netherlands is rare — this is a fish for anglers who follow the science and care about what it means.
Scientific Name: Alosa fallax
Also known as Fint, Elft (though Elft more commonly refers to allis shad)
- Deep-bodied and herring-like, with large, circular scales and a sharp, saw-toothed keel running along the belly — unmistakable in hand.
- Silvery flanks often show a row of dark blotches behind the gill cover; gill cover has radiating ridges and the upper jaw has a distinct notch.
- Rarely exceeds 40 cm in Dutch waters; the only reliable way to separate it from allis shad is counting gill-rakers (twaite: 40–60; allis: 90–130).
- An adipose membrane partially covers each eye — a subtle but consistent feature shared with allis shad.
What to know
Habitat Distribution
- Native to the Netherlands; spends most of its life at sea in the North Sea and Atlantic, entering rivers only to spawn.
- Declining numbers are still recorded in the lower reaches of the Rhine and Meuse during spring spawning migrations.
- Juveniles use estuarine and brackish coastal waters as nursery habitat before moving offshore.
- The species never established spawning populations in the Dutch section of the Rhine historically; current records are of migratory adults passing through.
Key Locations
- Lower Rhine (Neder-Rijn / Lek): declining numbers of migrating adults are still recorded here during spring runs.
- Lower Meuse: occasional spring records of twaite shad in the tidal lower reaches.
- Coastal North Sea waters: the species passes through Dutch coastal waters during its Atlantic migrations, occasionally turning up in coastal catches.
Specific Spots
- Lower tidal reaches of large rivers — shad follow the tide upstream and concentrate where current slows at bends or behind structure.
- Shallow gravel runs near deeper holding pools are classic spawning-adjacent areas; fish stage in the deep water and move onto the gravel at night.
- Estuarine channel edges where fresh and salt water mix attract staging fish before they push further upriver.
Twaite Shad FAQ
Answers from onWater's species guide.
What are the best lures and bait for Twaite Shad?
Small silver or gold spinners (sizes 1–3) and slim silver spoons in the 5–10 g range are the go-to across European shad fisheries, retrieved steadily across the current rather than worked with heavy action.
What flies work for Twaite Shad?
Small, sparse streamers on size 6–10 hooks, slim Clouser Minnows (which imitate small baitfish) in silver/white or chartreuse are a reliable starting point, swung across the current on a tight line.
When is the best time to fish for Twaite Shad?
Spring (April–June): the only realistic window, when migrating adults move through tidal river reaches on their spawning run. Outside the spring run, the species is at sea and effectively unavailable to freshwater or estuarine anglers.
How do you catch Twaite Shad?
Deliberate targeting of twaite shad in the Netherlands is extremely rare given how few fish now enter Dutch rivers. Anglers who do encounter them fish light spinning gear or fly tackle from the bank in tidal river reaches during the spring run, working small spinners or slim streamers across the current.
What do Twaite Shad eat?
In coastal and estuarine waters, shad feed on zooplankton, small crustaceans, and small fish, their gill-rakers are built for filter-feeding on tiny prey. Small spinners and slim silver lures imitate the flash of the small baitfish they chase.
