Ruffe
Ruffe are small, bottom-hugging members of the perch family, native to England and widespread across canals, rivers, and lakes.
Most anglers encounter them accidentally while fishing for perch or bream, but they're a genuine target for junior and match anglers. They fight with surprising rigidity and demand careful handling — those spines are sharp.
Scientific Name: Gymnocephalus cernua
Also known as Pope
- Olive-green to golden-brown back with irregular dark blotches along the flanks, fading to a pale yellowish-white belly — similar to a juvenile perch but without the bold vertical bars.
- Two dorsal fins fused into one: the front section carries stiff, sharp spines; the rear section has soft rays. Gill covers are also spiny — handle with care.
- Large eyes relative to body size, and a slightly downturned mouth with bristly teeth. The head looks almost triangular and soft-skinned.
- Typical UK fish run 7.5–12 cm and 30–60 g; the rod-caught record stands at 148 g (5 oz 4 dm), which is a genuinely large ruffe.
What to know
Habitat Distribution
- Native to England; widespread and fairly common from London north through the Midlands to North Yorkshire, with good numbers on northern canals and rivers.
- Recorded in Bassenthwaite Lake in the Lake District, where they established after being first noted in 1991, and across Leicestershire and Rutland waters.
- Favour slow-moving or still water — canal pounds, the lower reaches of rivers, and lake margins — rather than fast, well-oxygenated upland streams.
- Tolerant of brackish conditions, so they can turn up in tidal river reaches and estuaries as well as purely freshwater venues.
Key Locations
- Canal network across northern England — the Shropshire Union, Grand Union, and Fosdyke drains all hold reliable ruffe populations.
- Bassenthwaite Lake, Cumbria — ruffe established here after 1991 and are now widespread throughout the lake.
- Midlands rivers and stillwaters from Leicestershire northward to North Yorkshire, where they are recorded as fairly frequent.
- Tidal and lower river reaches in eastern England, where slow, silty conditions suit them and brackish tolerance extends their range.
Specific Spots
- Deepest, muddiest sections of canal pounds — ruffe hug the bottom and concentrate where silt holds invertebrates and there's little current to fight.
- Lock cuts and lock approaches, where slower water and disturbed substrate concentrate food; the Fosdyke and Grand Union Canal locks are known ruffe spots.
- Slack margins and bays on rivers, especially where weed or submerged debris provides cover from pike and zander.
- Deeper water in lakes during daylight; they move shallower at dawn and dusk to feed more actively.
Ruffe FAQ
Answers from onWater's species guide.
What are the best lures and bait for Ruffe?
Chopped or whole small worm is the go-to bait, dendrobaena sections or a single red worm fished hard on the bottom. Ruffe bite fast and swallow deep, so strike early. Single maggot or double maggot on a small hook also works well, particularly on canals where maggot is the standard feed.
When is the best time to fish for Ruffe?
Present and catchable year-round on canals and rivers, ruffe don't shut down in winter the way many species do. Most active and easiest to locate from spring through autumn when water temperatures are above 10°C and feeding is consistent.
How do you catch Ruffe?
Most UK anglers catch ruffe while fishing the bottom for perch or canal species with light float tackle and worm or maggot. Deliberately targeting them means fishing a small worm hard on the deck in the deepest, slowest section of a canal pound or lock cut, striking quickly as ruffe swallow bait fast.
What do Ruffe eat?
Primarily bottom-dwelling invertebrates, midge larvae (bloodworm), mayfly larvae, small worms, and aquatic snails. A small piece of chopped dendrobaena worm on a size 18–20 hook fished hard on the deck is the standard approach.
Where do Ruffe live?
Native to England; widespread and fairly common from London north through the Midlands to North Yorkshire, with good numbers on northern canals and rivers. Recorded in Bassenthwaite Lake in the Lake District, where they established after being first noted in 1991, and across Leicestershire and Rutland waters.
