Head to head
Northern Pike vs Muskellunge
The northern pike and the muskellunge are the two large members of the pike family in North America, they share the same lakes and rivers across a broad band of the continent, and a big one of either can look, at the side of a boat, much like the other. They also hybridise, producing the tiger muskie. But there are reliable ways to tell them apart, and they fish very differently.
| Northern Pike | Muskellunge | |
|---|---|---|
| Range | North America, Europe, and Asia | North America only |
| Maximum size | Around 1.3 m and 25 kg | Over 1.8 m and 30 kg |
| Markings | Light spots on a dark body | Dark bars or spots on a light body, or nearly plain |
| Tail lobes | Rounded | Pointed |
| Cheek and gill-cover scales | Fully scaled on the upper half of both | Only the upper half of the cheek and gill cover scaled |
| Pores under the jaw | Five or fewer on each side | Six to nine on each side |
| Abundance and catchability | Common and aggressive | Low density; the fish of ten thousand casts |
| Hybrid | Tiger muskie (pike x muskie), fast-growing and usually sterile | Tiger muskie (pike x muskie), fast-growing and usually sterile |
Pike vs Muskie: common questions
What is the single most reliable way to tell a pike from a muskie?
Count the small sensory pores on the underside of the lower jaw, on one side. A northern pike has five or fewer of these pores per side; a muskellunge has six to nine per side. It is a fiddly check but it does not depend on colour or pattern, which vary a lot. Backing it up: look at the cheek and the gill cover, because a pike has both fully scaled on the top half while a muskie has scales only on the upper part of the cheek and the very top of the gill cover, leaving the lower gill cover bare. And the tail lobes are rounded on a pike, more sharply pointed on a muskie.
Why is the muskie called the fish of ten thousand casts?
Because it genuinely is that hard to catch. Muskellunge live at naturally low population densities, so there simply are not many of them in a given lake, and they are apex ambush predators that may feed heavily for a short window and then ignore lures for days, following a bait right to the boat and turning away at the last second. Serious muskie anglers put in long hours over many outings for each fish, and the "ten thousand casts" figure, while not literal, captures the commitment involved. A northern pike, by contrast, is often the fish that a beginner catches by accident while after something else.
What is a tiger muskie?
It is the hybrid of a northern pike and a muskellunge, which occurs naturally where the two overlap and is also produced deliberately in hatcheries for stocking. Tiger muskies have bold, irregular dark tiger-striping over a lighter body, rounded fins, and they grow unusually fast because, like many hybrids, they put energy into growth rather than reproduction, since they are almost always sterile. Fisheries managers stock them into waters where a controllable trophy predator is wanted without the risk of a self-sustaining muskie population establishing. They are prized by anglers as hard-fighting fish that reach a good size quickly.
