Ide
The ide is a native cyprinid with a genuine following among Dutch anglers who fish rivers and canals. It rises to surface insects like few other coarse fish will, which makes it unusually interesting on both float and fly tackle.
The Waal, IJssel, and the canal network all hold good populations, and post-spawn fish in spring feed with real urgency.
Scientific Name: Leuciscus idus
Also known as Winde, Orfe
- Stocky, broad-bodied silver fish with a grey-green to blue-grey back and white belly — noticeably chunkier than a roach of the same length.
- Pelvic and anal fins are orange-red to pink, especially vivid on adults — the clearest field mark when the fish is in hand.
- Eyes are yellow-green, not red; scales are smaller and more numerous than roach (55–61 along the lateral line vs. 42–45 in roach).
- Common fish run 30 cm; large specimens reach 50–60 cm and can exceed 4 kg — broad and substantial at that size.
What to know
Habitat Distribution
- Native to the North Sea basin, which includes the Netherlands; found naturally in the larger river systems and connected still waters.
- Present in the main rivers — Waal, IJssel, Maas, and Rhine branches — as well as polderkanalen and larger urban canals.
- Tolerates both flowing and still water; favours the upper water column and is regularly seen feeding at the surface in summer.
- Also kept as an ornamental pond fish, from which escapes into connected waterways are common.
Key Locations
- Waal — strong current and well-spaced groynes make this one of the best rivers for ide, particularly in spring and early summer.
- IJssel — recommended by Dutch fly anglers specifically for ide and asp; the groynes at the upstream and downstream ends of bends concentrate fish.
- Amsterdam and Utrecht canal networks — urban canals hold good populations of ide that rise to surface food in summer, accessible from the bank without a boat.
- Maas and its side channels — slower reaches hold ide alongside bream and roach; float fishing from the bank is the typical approach here.
Specific Spots
- Groynes on the Waal and IJssel concentrate ide in the slack water behind the stone structures, especially in spring when fish stage before moving upstream to spawn.
- On canals and slower rivers, look for ide rising under overhanging trees or along weedlines where insects fall onto the surface.
- Shallow, flooded margins and gravel shallows draw fish during the early-season spawn; after spawning, fish drop back to the nearest deeper run or pool edge.
- Mid-water and just below the surface over clean bottom — ide rarely hug the riverbed the way bream or tench do.
Ide FAQ
Answers from onWater's species guide.
What are the best lures and bait for Ide?
Bread flake fished unweighted on the surface is the most direct method when fish are rising, simple, cheap, and hard to beat in summer. Maggots, casters, and sweetcorn on a float rig cover subsurface feeding; groundbaiting with loose feed draws fish into a swim on canals.
What flies work for Ide?
Dry flies that suggest adult insects, Elk Hair Caddis, Klinkhåmer, or a simple Adams, are the go-to when ide are visibly rising on summer evenings; match the size of what's on the water rather than the exact species.
When is the best time to fish for Ide?
Early spring (March–April), spawning fish are active and concentrated in shallow margins; post-spawn feeding makes this one of the most productive windows of the year. Late spring through summer (May–August), surface feeding peaks on warm evenings; the best time for dry-fly and bread-flake fishing.
How do you catch Ide?
Most Dutch anglers fish ide from the bank with float tackle or surface bread, targeting visibly rising fish in canals and river margins during summer evenings. Fly fishing for rising ide on the IJssel and Waal has a small but growing following, with anglers working the slack water behind groynes.
What do Ide eat?
Insects and insect larvae are the core of the diet in warmer months, surface-feeding ide are taking flies, beetles, and anything else that lands on the water, which is exactly why a dry fly or a piece of unweighted bread flake works so well.
