Silver Bream
Silver bream (witvoorn or kolblei in Dutch) are a common catch across the Netherlands, turning up in canals, poldersloten, and the slower reaches of the big rivers.
Most run small — under 200g — and they mix freely with roach, common bream, and rudd, which means they show up regularly on float rigs aimed at other species. A dedicated following exists among match anglers who fish Dutch canals.
Scientific Name: Blicca bjoerkna
Also known as Kolblei, Witvoorn, White Bream
- Deep, laterally compressed body, silver flanks, and a darker grey-brown back — similar to common bream but noticeably smaller and rounder-eyed.
- The most reliable ID mark: reddish pectoral fins with grey tips, and fewer than 10 rows of scales between the dorsal fin and the lateral line (common bream has 11 or more).
- Eyes are large relative to the head — more prominent than on common bream of similar size.
- Typical fish run 15–25 cm and under 350g; anything over 500g is a good fish, with exceptional specimens reaching around 1 kg.
What to know
Habitat Distribution
- Native to the Netherlands and widespread — found throughout the lowland river systems including the Maas, Waal, IJssel, Lek, and Nederrijn catchments.
- Thrives in canals, poldersloten (drainage ditches), and slow-moving or still waters with soft, muddy bottoms and some aquatic vegetation.
- Tolerates the turbid, boat-disturbed water typical of Dutch navigation canals, where it often mixes with roach and common bream.
- Prefers shallower, slower water than common bream — small polder lakes and canal margins are classic habitat.
Key Locations
- Dutch navigation canals throughout the western and central Netherlands — accessible, fish-holding, and well-suited to light float tactics.
- Polder lakes and drainage ditches (poldersloten) across the provinces of Zuid-Holland, Noord-Holland, and Utrecht hold resident populations year-round.
- Slower reaches of the Maas around Boxmeer and the lower IJssel valley, where silver bream mix with roach and common bream in slack margins.
Specific Spots
- Canal margins with overhanging vegetation or moored boats provide shade and concentrate feeding fish, especially in summer.
- Silver bream feed more in mid-water than hard on the bottom — look for them just off weed beds where invertebrates and plankton drift through.
- Slack water behind bridge supports or lock entrances holds fish out of main current, particularly in river systems.
- Shallow bays and reed-lined edges of polder lakes attract fish during warmer months when invertebrate activity peaks.
Silver Bream FAQ
Answers from onWater's species guide.
What are the best lures and bait for Silver Bream?
Maggots, pinkies, and casters are the most consistent baits, fish one or two on a small hook with loose feed or groundbait to hold the shoal. Double caster on a light rig is a proven Dutch canal combination.
When is the best time to fish for Silver Bream?
Spring (April–May): fish become active as water warms; pre-spawn fish feed well in canal margins and shallow polder lakes. Summer (June–August): peak feeding activity; early morning sessions before boat traffic starts are most productive on canals.
How do you catch Silver Bream?
Most Dutch anglers encounter silver bream while float or pole fishing canals and polder waters for roach or common bream. Fishing a light float rig with maggots or casters at mid-water depth, with regular loose feed to hold a shoal, is the standard approach from the bank or a low platform.
What do Silver Bream eat?
Feeds on insect larvae (especially chironomid/midge larvae), small crustaceans, and plankton, mid-water feeding is more common than rooting in the mud like common bream. Small maggots, pinkies, and casters directly imitate this forage and are the go-to baits in Dutch canals.
Where do Silver Bream live?
Native to the Netherlands and widespread, found throughout the lowland river systems including the Maas, Waal, IJssel, Lek, and Nederrijn catchments. Thrives in canals, poldersloten (drainage ditches), and slow-moving or still waters with soft, muddy bottoms and some aquatic vegetation.
