    Organism type: fish
    The northern pike, Esox lucius, is a predatory freshwater fish that is an opportunistic feeder. It is common in lakes, basins and rivers in the United States, Canada, central Asia, Siberia and many places in Europe. It is also present in the Aral, Arctic, Baltic, Barents, Black, Caspian, North and White seas and Atlantic basins. E. lucius exhibits genetic differentiation among its worldwide populations.
    Occurs in:
    lakes, water courses
    General impacts
    Esox lucius can cause the alteration of fish community species composition, by both predation and competition. As E. lucius is an opportunistic feeder, it is able to adapt to whatever prey fish are present. E. lucius may also hybridise with native fish species, e.g. E. masquinongy in the United States and Canada. (Fuller 2010; Harvey 2009).

    Management information
