Esox lucius, is a fish that lives in freshwater and brackish water in Europe, North Asia and in a wide belt through North America. In Denmark, pike is common in all large and small freshwater, both lakes and streams as well as in brackish water throughout the Baltic Sea area up to the southern Sound and the Småland waters.

The pike is green with yellow marbles and is characterized by its broad flat head. Adult pike are typically darker than juveniles. The dorsal and gill fins are located opposite each other far back on the body. The mouth is large with rows of pointed teeth in the jaws and all the way down to the palate. Usually the pike can grow over a meter before it dies of aging and can then weigh up to 8-15 kilos. It is thus one of Denmark’s largest freshwater fish.
