Freshwater · Spring through autumn; dawn surface hunts in summer
Asp
Leuciscus aspius
The predator of the carp family: a streamlined hunter that smashes into bleak shoals at the surface with an audible splash. It lives in big central European rivers and is taken on fast-fished lures at dawn. Also spread through the Baltic margins and Dutch rivers.

Identifying features
- Streamlined torpedo body with an upturned, pointed mouth built for surface hunting
- Lower jaw slightly upturned with a distinct knob fitting a notch in the upper jaw
- Large eyes and a deeply forked tail on a powerful tail stalk
- Silvery-blue back and flanks with fins often grey to reddish
- Small scales and a lateral line that dips low over the belly — no other cyprinid looks this predatory
Habits
- The cyprinid family's only true predator — it hunts fish rather than grazing plants or bottom food
- Smashes into bleak shoals at the surface with an audible splash, often at dawn and dusk
- Males fight hard and run fast in current, using the flow against the angler
- Spawns in spring over gravel in flowing water
- Moves into slower, deeper water in winter
Distribution
Where to find them
- Rhine, Elbe and Danube currents at groyne heads and bridges
- Dutch river branches and harbour entrances
- Weirs and lock outflows of large lowland rivers
Where they live
How to catch them
Fast spinning in the current River
Rig: Medium spinning rod with small spoons, crankbaits or surface lures cast across the current and retrieved fast with pauses around groynes and weirs
Bait/lure: Small spoons, crankbaits, surface lures
Key tip: Cast to the splash of hunting asp and retrieve fast — slow presentations are usually ignored.
Bank spinning during the evening hunt Shore
Rig: Long spinning rod from bank or boat at a river mouth or harbour entrance, with long casts to rising shoals
Bait/lure: Bleak-imitating soft plastics, small spoons
Key tip: Fish first and last light and cast precisely to rising or splashing bleak; use barbless singles for safe release.

- Rod: Fast medium spinning rod 7-9 ft for long lure casts
