Common Roach

Roach are the backbone of Dutch coarse fishing.
Native to the Netherlands and present in virtually every canal, polder ditch, and slow river in the country, they're the fish most beginners catch first and the fish serious pole anglers travel from the UK specifically to target.
Big roach — anything pushing 1 kg or more — take real skill to find and fool.
Scientific Name: Rutilus rutilus
Also known as Blankvoorn, voorn
- Bluish-silver flanks fading to white on the belly; the red-orange fins and distinctly red iris make roach easy to identify in hand.
- Deeper-bodied than a dace or rudd; the dorsal fin sits directly above the pelvic fins — a quick field check that separates roach from similar cyprinids.
- Most fish run 15–25 cm; anything over 35 cm and approaching 1 kg is a specimen worth noting. Maximum length around 50 cm.
- Scales are large and firmly attached, numbering 39–48 along the lateral line — noticeably fewer than on bream.
What to know
Habitat Distribution
- Native throughout the Netherlands; one of the most widely distributed freshwater fish in the country, found from Groningen to Zeeland.
- Canals and poldersloten (polder ditches) are their heartland — slow, nutrient-rich water with soft bottoms suits them perfectly.
- Also common in the larger river systems including the Rijn, Maas, and IJssel, typically in slacker water away from the main current.
- Tolerates slightly brackish conditions, so roach turn up in tidal reaches and the broader delta waters of Zuid-Holland and Zeeland.
Key Locations
- Hellevoetsluis area canals near Rotterdam — well-known among UK and Dutch pole anglers for large mixed bags of roach and bream.
- The polder canal networks of Zuid-Holland and Noord-Holland hold dense roach populations in slow, deep ditches and interconnected waterways.
- The IJsselmeer margins and connected polderwater produce roach alongside bream, particularly in autumn.
- Urban canals in cities like Amsterdam and Utrecht hold roach year-round and are accessible on a standard VISpas.
Specific Spots
- Canal junctions and lock entrances concentrate roach — the slight current and depth change draw fish, especially in cooler months.
- Weedbed edges in summer: roach feed along the margins of submerged vegetation where invertebrates and algae accumulate.
- Deeper holes and bends in polder ditches hold fish through winter when shallow water cools rapidly.
- Bridge pilings and moored boats create shade and shelter; roach stack up beneath them during bright midday conditions.
Common Roach FAQ
Answers from onWater's species guide.
What are the best lures and bait for Common Roach?
Maggots and pinkies are the standard roach bait across Dutch waters, fish them on the hook with a loose-fed or groundbait-bound feed to build a swim. Bread punch (a small disc of compressed bread on a fine hook) works particularly well in winter when roach feed slowly and want a soft, slow-sinking bait.
What flies work for Common Roach?
Small nymphs, Pheasant Tail Nymphs and Hare's Ear Nymphs imitate the midge larvae and small invertebrates roach graze on, fished under a strike indicator in 1–2 metres of water.
When is the best time to fish for Common Roach?
Spring (March–May): fish become active as water warms; pre-spawn roach feed heavily and respond well to maggot and caster on the pole. Summer (June–August): consistent fishing through the day in early morning and evening; weedbed margins and shaded spots under bridges produce well.
How do you catch Common Roach?
Most Dutch anglers target roach from the bank using a long pole with a light float rig, feeding groundbait or loose maggots to build a shoal in the swim. Feeder and waggler tactics work on wider open waters. Sessions are typically a few hours, often timed around dawn or dusk for the best bites.
What do Common Roach eat?
Bottom-dwelling invertebrates, bloodworm (midge larvae), small worms, and freshwater snails, make up the bulk of the diet, which is why maggots and pinkies fished on the bottom or mid-water are the go-to baits across Dutch canals.
