Pike perch, any of several freshwater food and game fishes of the family Percidae (order Perciformes), found in Europe and North America. Although more elongated and slender than perches, pike perches have the two dorsal fins characteristic of the family. They are, like perches, carnivorous, and as adults they feed largely on other fishes. The European pike perch, or zander, is found in lakes and rivers of eastern, central, and (where introduced) western Europe. It is greenish or grayish, usually with darker markings, and generally attains a length of 50–66 cm (20–26 inches) and a weight of 3 kg (6.6 pounds).
