Muskellunge, also known as muskies or musky, are carnivorous fish that feed primarily on other fish. They have a preference for larger prey such as yellow perch and suckers but will also eat smaller species like crayfish and frogs. Muskies typically ambush their prey by hiding in weeds or near structure before attacking with great speed and power. In various conditions, such as the time of year, water temp., and access to sustenance, their dietary habits can differ.
