Natural History

Habitat

Food

• Pike will eat insects, but as voracious predators they feed primarily on fish and other vertebrates.

Reproduction and Growth

Breeding Behaviour

• Spawning occurs in flooded areas of vegetation in early spring, often when ice is still on the lakes.
• Northern pike are broadcast spawners, with females and males swimming alongside each other releasing their eggs and milt (excretion of male sperm cells) into the water.
• Fertilized eggs stick to vegetation and incubate. Hatching occurs in 12 to 17 days.
• Young of the year are present as early as May.
