This pie chart shows the relative likelihood of observing particular other species commonly observed near Esox lucius

Aquatic Regions:

Circumpolar in fresh water. North America: Atlantic, Arctic, Pacific, Great Lakes and Mississippi River basins from Labrador to Alaska and south to Pennsylvania, Missouri and Nebraska, USA. Eurasia: France to eastern Siberia, south to northern Italy. Absent from northern Norway and northern Scotland. Introduced into other countries. Several countries report adverse ecological impact after introduction.

Habitat Overview:

Occurs in clear vegetated lakes, quiet pools and backwaters of creeks and small to large rivers[1]. Usually solitary and highly territorial. Enters brackish water in the Baltic.

Biome:

Fresh water, brackish water. Demersal.

Predators:

Eggs and young are preyed upon by fishes, aquatic insect larvae, birds, and aquatic mammals[2].

Parasites:

This fish can be heavily infested with parasites, including the broad tapeworm which, if not killed by thorough cooking, can infect human; is used as an intermediate host by a cestode parasite which results to large losses in usable catches of lake whitefish ( Coregonus clupeaformis ) in some areas; also suffers from a trematode which causes unsightly cysts on the skin[3].
