Dace
Leuciscus leuciscus
The dace is a fast-water silver fish of clean rivers, shoaling in the runs below weirs and taking insects with lightning-fast bites. Delicate on the float and fun on fine tackle, it is the classic summer river fish — rarely big, but always willing in good water.

Identifying features
- Slim, torpedo-shaped silvery body built for fast water
- Concave anal fin with a notched edge — the separator from chub
- Small mouth; upper jaw slightly overhanging
- Blue-green sheen on the back; fins pale, anal and tail tinged grey
- Scales smaller and finer than chub's; no red fins except faintly in spring
Habits
- Shoals in fast, clean water — a good water-quality indicator
- Feeds on insect larvae, small crustaceans and surface insects
- Lightning-fast bites; dace steal bait in a flash
- On the fin all day in summer; gathers in deeper runs in winter
- Spawns in spring over clean gravel in fast water
Distribution
Where to find them
- Runs below weirs on chalk and lowland rivers
- Gravel riffles and fast shallows
- Bridge runs and mill glides
Where they live
How to catch them
Stick-float trotting in river runs River
Rig: Stick float on a 13-14 ft rod, size 16-18 hook, bait trotted down glides and runs with the flow
Bait/lure: Maggot or caster with loose-fed hemp
Key tip: Strike instantly — dace bites are the fastest in the river; the float is barely seen before the bait is gone.
Summer surface fishing on riffles River
Rig: Light surface presentation — small dry fly on fly tackle or a freelined maggot — cast to shoals on shallow riffles
Bait/lure: Small dry fly or a single surface maggot
Key tip: Cast above the shoal and let it drift naturally; dace rise freely on warm evenings.
