Black Bullhead
The black bullhead is a North American catfish introduced to the Netherlands, where it has established itself in slow, weedy, low-oxygen waters that most other species avoid.
It's a modest-sized fish — rarely over a pound in Dutch waters — but it bites willingly after dark and gives younger or casual anglers reliable action on simple gear. Not a primary target for most Dutch anglers, but a genuine catch in the right spots.
Scientific Name: Ameiurus melas
Also known as Zwarte dwergmeerval, black bullhead catfish
- Dark brown to black on the back and sides, fading to yellow or white on the belly — easy to distinguish from the similar brown bullhead by its darker overall coloring.
- Black chin barbels (the 'whiskers') are the key ID mark; brown bullhead has pale or mottled barbels. Tail fin is squared off, not forked like channel catfish.
- A pale tan crescent at the base of the tail is a reliable field mark. No scales anywhere on the body.
- Typical Dutch fish run 15–30 cm; anything over 35 cm is a good one. Maximum size rarely exceeds 1 kg in European waters.
What to know
Habitat Distribution
- Native to North America; introduced to Western Europe in the late 19th century. Confirmed as an introduced species in the Netherlands, where it competes with the more established brown bullhead in still and slow waters.
- Thrives in lentic (still or very slow) systems — ponds, ditches, weedy lakes, and sluggish backwaters — particularly where oxygen levels are low and other species struggle.
- Tolerates turbid, warm, and even slightly brackish water better than most freshwater fish, which helps it persist in the low-lying polder landscape of the Netherlands.
- In the Netherlands and Belgium, the brown bullhead tends to dominate still-water systems, but black bullhead are present and have been documented in overlapping habitats.
Specific Spots
- Soft muddy bottoms in the deepest part of a pond or ditch — black bullheads root along the bottom after dark, so focus on the lowest, murkiest zones.
- Dense weed edges and lily pad margins at night; the fish use vegetation as cover and hunt along the weedline after sunset.
- Sheltered bays and canal corners with little current and accumulated organic debris on the bottom — exactly the kind of dead-water pockets common in Dutch polder ditches.
Black Bullhead FAQ
Answers from onWater's species guide.
What are the best lures and bait for Black Bullhead?
Earthworms and red worms are the go-to bait, fish them on the bottom near weed edges or in open muddy areas after dark. Hard to beat for simplicity and effectiveness. Small pieces of cut fish or liver also work, particularly for larger fish.
When is the best time to fish for Black Bullhead?
Late spring through summer (roughly May–September) is the most productive window, when water temperatures are warm and the fish feed actively at night. Activity drops sharply in autumn and the fish are largely dormant through winter in the cold, shallow waters typical of Dutch lowland systems.
How do you catch Black Bullhead?
Most Dutch anglers encounter black bullhead incidentally while fishing for other species in ponds and ditches. Deliberate targeting means fishing after dark with worm or cut bait on a simple bottom rig in weedy, still-water habitats, polder ditches and small ponds are the most likely venues.
What do Black Bullhead eat?
Bottom feeders that eat worms, insect larvae, small crustaceans, and decaying organic matter. A simple earthworm or red worm on a small hook fished on the bottom is the most reliable approach, it directly imitates their natural forage.
Where do Black Bullhead live?
Native to North America; introduced to Western Europe in the late 19th century. Confirmed as an introduced species in the Netherlands, where it competes with the more established brown bullhead in still and slow waters.
