European sprat
Fish · Last reviewed 2026-08-11
A small shoaling clupeid of coastal and shelf water, abundant enough to feed most of the predators in the northern European sea and to support a large fishery besides.
A supporting record, not a fishing profile
This page is here so FishingHQ can describe a biological relationship accurately — usually because a fish covered elsewhere on the site feeds on this. It covers what it is, where it lives and the evidence behind that relationship, and deliberately nothing about methods, bait or tackle. Its presence here is not a statement that anybody fishes for it.
The sprat is a small herring relative that forms dense shoals in coastal water and estuaries, often in enormous numbers and often close inshore in winter.
Its significance is entirely a matter of abundance. Sprat are oily, they shoal tightly, and they occupy shallow water at exactly the times when predators are looking for a concentrated meal. Autumn and winter sprat shoals moving inshore are the reason bass, cod and a good deal else are catchable where and when they are, and the sudden appearance of a sprat shoal changes the fishing over a stretch of coast within a day.
Sprat are also taken commercially in quantity for canning, for fishmeal and, at small sizes, as part of what is sold as whitebait.
The species is here because sprat appears by name in the recorded diets of cod, sea bass, mackerel, bonito, tuna and salmon, and encoding those relationships against a genuine sprat record rather than against some other small silver fish is the whole point of the graph-precision rule.
Identification
FishingHQ holds no photograph of this species whose identity and licensing it can vouch for, so it is not showing one. Misidentified fish photographs teach identification wrongly, and a picture with an unchecked caption would be worse than none. The identification points below are what to look at instead.
- Scientific name
- Sprattus sprattus
- Family
- Clupeidae
- Water
- Saltwater, Brackish
- Conservation status
- Least Concern
- Regions
- Britain & Ireland, Northern Europe, Western Europe, Mediterranean
- Small, laterally compressed silver fish with a deeply forked tail and a single soft dorsal fin.
- Sharply keeled belly with distinctly serrated scutes that can be felt as a saw edge along the underside.
- Distinguished from a young herring by the position of the dorsal fin, which begins behind the pelvic fins in the sprat.
- No dark spot behind the gill cover, which separates it from small shads.
Size
- Typical
- 9–14 cm
- Large
- up to about 16 cm
Lifecycle and reproduction
Sprat mature at one to two years, live to about five or six, and grow fast. Populations are dominated by a few year classes at a time, so numbers swing sharply between good and poor recruitment years.
Spawning occurs over an extended period from late winter into summer depending on region, with buoyant eggs released into the water column in coastal and shelf water. Larvae drift with currents before shoaling as juveniles inshore.
Feeding and senses
A planktivore. Sprat feed on copepods and other small planktonic crustaceans, taking them individually by sight rather than by filtering. Feeding activity tracks the plankton cycle and is concentrated in the lighter half of the year.
Vision for feeding, and a well-developed lateral line for shoaling. Sprat shoals respond as a unit to the pressure disturbance made by an approaching predator, which is what produces the visible bait-ball behaviour that draws birds.
Through the year
Moves offshore into deeper water in summer and returns to shallow coastal water and estuaries in autumn and winter in much of its range. That inshore winter presence is the event a great deal of northern European predator fishing depends on.
Distribution
The north-east Atlantic from Norway and the Baltic south to Morocco, including the North Sea, the Mediterranean and the Black Sea, in coastal and shelf waters.
This is a biological range — where the species occurs, not a prediction that you will catch one. To browse the fishing geography FishingHQ holds, start at fishing places.
Why anglers care
Not a rod-and-line target. Sprat are widely used as a deadbait, netted or bought frozen, and are far more important as the reason predators are present at all. The presence of a sprat shoal is a fishing signal rather than a fishing opportunity in itself.
Handling and returning
Handled by anglers almost exclusively as a dead bait. Frozen sprat used as bait should be disposed of responsibly rather than returned to the water, particularly where the source water differs from the one being fished.
Where to go next
Similar and related fish
Atlantic bonitoSprat and other small clupeids make up the rest of the diet where anchovy are scarce, which is why bonito appear in northern waters in some years and not others.- Atlantic horse mackerelLarger horse mackerel take sprat and other small clupeids, and shoals of both together are a common feature of autumn inshore water.
European sea bassAutumn and winter sprat shoals moving inshore are followed by bass, and a sprat shoal in a bay is one of the more reliable indications that bass are present.
Greater amberjackSmall shoaling clupeids are a principal prey where amberjack range overlaps them, and amberjack hunting behaviour is organised around driving such shoals against structure or the surface.- John DorySprat shoals over and around structure are prime dory prey: small, abundant, and slow to notice a predator approaching edge-on.
- SpurdogSmall clupeids are a staple, and the reason spurdog shoals follow bait concentrations rather than holding ground.
