The northern pike (Esox lucius) and the muskellunge, commonly known as Musky (Esox masquinongy), both hail from the Esox genus, part of the Esocidae family. They are freshwater fish species, predominantly occupying the Northern Hemisphere. Though they share many common characteristics, a few significant differences set them apart.
Order, Family, and Genus Distinction
Scientific classification of organisms often follows a hierarchy: domain, kingdom, phylum, class, order, family, genus, and species. Pike and Musky, belonging to the same genus Esox, are under the order of Esociformes, which typically include pike-like fishes. The family is Esocidae, home to pikes and pickerels. Despite their shared genus, differences emerge when distinguishing the two species, Esox lucius (pike) and Esox masquinongy (musky).
Identifying Pike and Musky: Visual Differences
Though Pike and Musky bear similar body shapes, they have several distinct features to tell them apart visually.
Pike
Northern Pike usually have a dark greenish to brown body color with lighter shades on the belly. They sport irregular, short, lighter-colored spots (often yellowish or white) on their flanks, creating a contrasting pattern against the darker body color. Pike typically have fewer than six pores under their jaw, a handy detail for fishers to note when identifying their catch.
The easiest way to distinguish Pike from Musky is by looking at their tail fin: it's much more rounded.
Musky
Musky tend to have vertical bars or spots on their flanks, contrasting with the Pike's horizontal orientation. Their body colors can range from green to brownish, similar to the Pike, but their patterns are more varied and may even seem random. Muskies typically have more than six sensory pores under their lower jaw, distinguishing them from Pike.
The easiest way to distinguish Musky from Pike is by looking at their tail fin: it's much more pointy.
Global Distribution of Pike and Musky
Pike
The northern pike is indigenous to North America and Eurasia, including Russia, Scandinavia, the British Isles, and parts of Western Europe. In North America, they are abundant in Canada and the Northern United States, including the Great Lakes region and the Missouri River Basin. Over the years, they have also been introduced to other regions for sport fishing.
Musky
On the other hand, Musky are predominantly found in North America. Their native habitats are the northern United States and the southern fringes of Canada, stretching from Maine and the Appalachians to the midwestern states and up into the Canadian provinces of Quebec and Ontario. They are also prevalent in the Great Lakes region.
Fishing Techniques: Targeting Pike vs. Musky
When it comes to fly fishing, different strategies and equipment may be used when targeting Pike versus Musky.
Pike
Pike are aggressive predators and are known to bite on a wide range of lures. Large, brightly colored lures or those that mimic the appearance of their prey are effective. Alternative fast and slow strips. When you see a pike chasing your fly instinctively you might feel like slowing down your strip speed, while actually the opposite might be more effective. Imitating a baitfish that's trying to flee can result in some explosive strikes! Consider using heavy tippets (fluorcarbon) to prevent the pike's sharp teeth from cutting the line.
Musky
Fishing for Musky, often referred to as the "fish of ten thousand casts," requires more patience than pike. They are less likely to bite than Pike, and when they do, it's often a thrilling fight. Just like with Pike: large, flashy lures are commonly used to attract these elusive fish. Musky also have sharp teeth, so use heavy tippet (fluorcarbon).
