The muskellunge (scientific name "Esox masquinongy") is a freshwater game fish. It is the largest member of the Esox (Pike) family. The muskellunge is also called the muskie or maskinonge (Canada). It is native to northern and eastern North America. Muskies have been introduced into other U.S. states. There usually are not many muskellunge in a lake. They are large solitary (on their own) apex predators and need large amounts of water to feed their appetites. Muskies are carnivorous and eat other fish. They are ambush feeders who will attack anything that moves in or on the water.
