Species ( Esox masquinongy ) of somewhat uncommon pike valued as a fighting game fish and, to a lesser extent, as a food fish.
It inhabits weedy rivers and lakes of the North American Great Lakes region. It averages about 20 lbs (9 kg), but may grow to 6 ft (1.8 m) long and weigh 80 lbs (36 kg) or more, making it the largest fish in the pike family. The lower part of the cheeks and the gill covers are scaleless.
