How does it look?

The northern pike, characterized by its torpedo-shaped and streamlined body slightly flattened from the sides, boasts a distinctive pike-like head adorned with numerous sharp teeth. Known for its remarkable growth potential, females generally surpass males in size. The largest recorded male measured 137 cm, weighing 28.4 kg, while females can reach up to 150 cm, weighing 35 kg.

The dorsal region of the northern pike showcases a greenish-blue hue, while the sides exhibit shades of greenish-grey or brownish with yellowish spots. The transition from the greenish tone to white occurs towards the belly. In habitats with dark, silty bottoms in deep rivers, lakes, and ponds, the coloration tends to be darker. Conversely, in rivers and lakes with sandy bottoms, it takes on a golden hue, and in ponds overgrown with grass, it appears greenish-yellow. The fins of the northern pike also display a mottled pattern, aiding in effective camouflage among aquatic plants. With prominently protruding eyes, this species enjoys excellent visibility over a wide area, particularly when in a stationary position.

Where does it live?

The northern pike, a predatory freshwater fish, is commonly found in many rivers and lakes in Latgale. However, it is typically absent in small, densely overgrown closed lakes. The widespread distribution of the northern pike can be attributed to its adaptability to various environments, thriving in rivers, lakes, or ponds with sufficient oxygen, abundant food sources, suitable spawning locations, and zooplankton for feeding the fry.

What does it eat?

The main food sources for the northern pike include fish, with perch and crayfish becoming prominent during the autumn. Cannibalism is also a common behavior observed among northern pike, where larger individuals may prey on smaller ones.

Interesting and important facts The northern pike is a solitary and highly territorial fish, often found living alone. In Latvia, these pikes can have a lifespan of up to 13 years. Reproductive maturity is reached between 1-7 years of age, typically when the fish attains a length of 20-60 cm. Female northern pikes exhibit a notable fertility during spawning, producing a range of 1.000 to 1.000.000 eggs.
