Ruffe
The small, spiny bottom-feeder that bites when nothing else will.
The ruffe, or pope, is a small, spiny relative of the perch that lives on the bottom of lowland rivers, canals and lakes. Rarely targeted on purpose, it is a familiar catch for float and feeder anglers, a hardy winter bait for zander and pike where allowed, and a fish every angler should be able to tell from a small perch.

How to identify it
A compact, perch-like fish rarely longer than 15 cm, with a large head, big eyes and a rough, spiny feel. Unlike the perch, its two dorsal fins are joined into one continuous fin, spiny in front and soft behind. The body is greyish-brown to olive with dark irregular blotches and speckles rather than vertical bars, the belly is pale and the fins are yellowish, never red. The gill covers carry sharp spines and the skin is slimy. The head shows visible sensory pits and canals used to find food in the dark. Confusable species are small perch and, in the Danube basin, the related striped and Balon's ruffe.
Where it lives
Ruffe live on the bottom of slow-flowing rivers, canals, reservoirs, ponds and lakes, and tolerate brackish water in the Baltic. They prefer soft or sandy bottoms in deeper, calmer water: harbour basins, marinas, deep bends, the foot of slopes and the slack water below weirs and bridges. They avoid strong current and dense weed, and are happy in turbid water, where their sensitive lateral-line system and large eyes give them an edge over sight-feeding competitors. Ruffe move in loose shoals and are famously tolerant of cold, low oxygen and poor water quality, which is why they thrive in canals and industrial harbours where other fish struggle. In summer they can be found shallower at night.
Season and behaviour
Ruffe spawn in March to May, often in several batches, laying sticky eggs on stones, roots and plants in shallow water. They feed throughout the year and are among the most reliable biters in cold water, which is why they dominate winter catches on canals and rivers and why ice anglers know them so well. Their peak feeding is in low light – dusk, night and dawn – when they use their lateral line to pick bloodworms, small crustaceans and fish eggs off the bottom; on overcast days they bite all day. Ruffe are also notorious egg predators in spring. In hot, bright weather they retreat to deeper water and feed mostly after dark.
Fishing methods
Nobody needs special tackle for ruffe: a light float rod with a small hook and a bait held on or just above the bottom, or a light feeder or ledger rig with a short hooklength, catches them wherever they are. They take small baits greedily and often swallow them, so use small hooks, strike early and carry a disgorger. On canals a pole or whip with a fine float and a maggot fished hard on the bottom is the most efficient; on rivers a light running ledger in the slack water below a weir or on a deep bend finds them in numbers. Anglers targeting zander and pike catch ruffe deliberately for bait where live bait is allowed. Because ruffe feed in low light, evening and night sessions produce the most.
Baits and lures
Ruffe eat almost anything small that moves on the bottom. Maggots, casters and bloodworm are the top baits, followed by small pieces of worm, brandlings and a single redworm. In winter, bloodworm on a tiny hook outfishes everything. They are not fussy about presentation but respond to scent, so a little groundbait laced with chopped worm or bloodworm draws a shoal quickly. Ruffe rarely take lures, though ice anglers catch them on tiny baited jigs.
Tips from the bank
- 01Fish the bait hard on the bottom – ruffe rarely rise more than a few centimetres to feed.
- 02Use small hooks (size 16–20) and strike at the first dip; ruffe swallow bait deep if given time.
- 03Handle them from the front: fold the dorsal spines down and mind the sharp gill-cover spines.
- 04If ruffe are stripping your bait when you want other fish, switch to bigger baits or lift the hookbait off the bottom.
- 05Evening and night sessions on canals and harbours give the biggest ruffe and the fastest bites.
- 06Where live bait is legal, a ruffe is a hardy, long-lasting bait for zander and pike.
- 07Wash your hands afterwards – the slime and spines are harmless but unpleasant.
Regulations
Ruffe are usually unregulated, but not everywhere: some countries list them as a protected native species or restrict their use as live bait, and in waters where they have been introduced they may be classed as invasive and must not be returned. Rules differ by country, region and water, so check the current regulations for the exact spot before you fish.

Frequently asked questions
How do I tell a ruffe from a perch?
The ruffe's two dorsal fins are joined into one continuous fin, its body is blotchy rather than barred, and its fins are yellowish instead of red. It is also much smaller, has larger eyes, a slimy skin and sharp spines on the gill covers.
Are ruffe good to eat?
Ruffe are edible and once formed the basis of traditional fish soups in parts of Europe, but they are so small and bony that few anglers keep them today. Most are returned or, where allowed, used as bait for zander and pike.
Can I use ruffe as live bait?
In many countries yes, and they are a hardy bait for zander, pike and eel, but live bait is banned or restricted on many waters and moving fish between waters is often illegal. Always check the local rules first.
When do ruffe bite best?
In low light – dusk, night and dawn – and throughout the cold months. They are among the few species that feed reliably in winter, which makes them the classic winter catch on canals, harbours and slow rivers.
How big do ruffe grow?
A typical ruffe is 8–15 cm long and weighs only a few tens of grams. Fish over 20 cm are rare; the commonly cited maximum is around 25 cm and a little under half a kilogram.
