Pro Pilkki 2 fish species

Pike (Esox lucius)

The northern pike (Esox lucius) is a predatory fish living in inland and coastal waters, found across most of northern Eurasia and North America. It is a vigorous species with a wide range that copes in many kinds of lakes and rivers as well as the low-salinity Baltic Sea. The pike's body is elongated and slender, and its fins are at the rear end.

• Size: In favourable conditions a female pike can grow to as much as one and a half metres and 35 kilograms.
• Habitat: The pike is found in Europe, Asia and North America.
• Food: It switches from zooplankton to a fish diet quite early, in its first summer when less than 10 centimetres long.
• Reproduction: A pike's first spawning is influenced by several factors, including temperature and the availability of food.
