European Perch
The European perch — known in the Netherlands as baars — is one of the most widely caught freshwater fish in the country. It lives in nearly every canal, lake, river, and polder water, making it accessible to anglers of all levels.
Perch are a genuine target species here, not just a bycatch, with dedicated guides and boat trips chasing specimens over 40 cm on waters like the Markermeer and Volkerak.
Scientific Name: Perca fluviatilis
Also known as Baars, Fluviatilis, Common Perch
- Greenish-yellow flanks crossed by 5–9 dark vertical bars — unmistakable in hand and unlike any other Dutch freshwater fish.
- Bright red-orange lower fins and a pronounced hump behind the head on larger fish; two dorsal fins, the first spiny.
- Most fish caught run 15–30 cm; fish over 40 cm are genuinely large, and the species can reach 60 cm in exceptional cases.
- Easily separated from zander by the barred pattern, red fins, and rounder body profile — zander are more elongated and lack the bars.
What to know
Habitat Distribution
- Native to the Netherlands and found across virtually the entire country — canals, polders, rivers, lakes, and tidal freshwater systems all hold perch.
- Thrives in slow or still water: the large inland lakes (Markermeer, IJmeer), the delta waters (Volkerak, Biesbosch), and the river backwaters along the Maas and Nederrijn.
- Urban waters hold fish too — Amsterdam's canals and the waters around Rotterdam are productive, and perch adapt well to the altered, managed landscapes that define much of the Dutch lowlands.
- Tolerates a wide range of water clarity and moderate turbidity, which suits the often murky conditions of Dutch polder and canal systems.
Key Locations
- Markermeer — a large inland lake with deep channels and open water; a major destination for guided perch, zander, and pike trips.
- Volkerak — a deep delta water in the southwest known for producing perch over 50 cm alongside record-class pike.
- Biesbosch — Europe's largest freshwater tidal system; dense reed beds, shallow lakes, and creek mouths hold perch throughout the season.
- Maas and Nederrijn river systems near Roermond — river backwaters and adjacent plassen (lakes) are productive for perch alongside zander.
- Amsterdam canals and the IJ — urban perch fishing in the heart of the city, accessible without a boat and productive year-round.
Specific Spots
- Weed edges and submerged vegetation are prime holding water — perch use the cover to corner smaller fish and invertebrates.
- Hard structure like bridge pilings, lock walls, mooring posts, and riprap concentrate fish year-round; in canals these are often the only real structure available.
- Drop-offs and depth transitions in larger lakes (Markermeer, Volkerak) pull fish vertically — perch suspend over deep channels and can be found anywhere in the water column when chasing baitfish schools.
- In tidal systems like the Biesbosch, creek mouths and the edges of reed beds funnel prey and hold perch through tidal movement.
European Perch FAQ
Answers from onWater's species guide.
What are the best lures and bait for European Perch?
Small soft-plastic shads and paddle tails on jig heads of 2–7 g are the most versatile perch lure in the Netherlands, fish them on a slow lift-and-drop retrieve along drop-offs, weed edges, and structure.
What flies work for European Perch?
Small streamers imitating roach or bleak fry, Clouser Minnows (which imitate baitfish with their weighted, jigging action) in white/chartreuse or white/olive, sizes 6–10, are the most reliable perch fly in Dutch waters.
When is the best time to fish for European Perch?
Spring (March–May): post-spawn fish recover and feed actively as water warms; weed edges and shallow bays produce well. Summer (June–August): early morning and evening sessions are most productive; look for surface-feeding schools chasing baitfish in open water.
How do you catch European Perch?
Most Dutch perch fishing happens from boats on the larger lakes and delta waters, using light spinning gear with soft-plastic jigs worked vertically or along structure. Shore fishing from canal banks and polder edges with spinners or float rigs is equally common and accessible to beginners.
What do European Perch eat?
Juveniles feed heavily on invertebrates, water fleas, insect larvae, and small shrimp, which is why small soft-plastic grubs, micro jigs, and tiny spinners work so well on fish under 20 cm. Larger perch shift to small fish: roach fry, bleak, and young perch are the main prey.
