Freshwater lakes, ponds and rivers, preferring clear, shallow, vegetated areas
Found throughout the northern half of North America, from Canada south to Nebraska, Missouri and Pennsylvania. Range extends farther than that of any other freshwater gamefish.
Northern pike are carnivorous fish that uses sharp teeth to feed on smaller fish, frogs, crayfish, small mammals and birds. Young feed on zooplankton and other aquatic invertebrates.
Adult northern pike have few natural predators, but young may be eaten by predatory fish or aquatic birds.
Spawning occurs in the shallows when water temperatures reach about 40 degrees Fahrenheit. Females broadcast eggs over aquatic vegetation while two or more males fertilize them. Females leave spawning area after 5 to 10 days. Males remain for several weeks, but do not protect eggs. Eggs hatch in two to four weeks, and young grow rapidly. Northern pike have been documented to live 24 years.
