pikeperch

Pikeperch, also known as zander, is a predatory freshwater fish of the perch family Percidae. Its scientific name is Sander lucioperca, and it has also been described under the genus Stizostedion. Native to Europe and western Asia, it has been introduced elsewhere in pursuit of sport fishing.

Description: Pikeperch has an elongated body with two dorsal fins, the first with spines and the second soft-rayed. It has a large mouth with sharp teeth and a coloration that ranges from olive to brown with vertical dark bars along the sides. Individuals can reach up to about 1 meter in length, though more commonly they measure 40 to 70 cm, with weights of several kilograms and some specimens approaching 10 kg.

Habitat and range: This species inhabits large rivers, lakes, and reservoirs with clear to moderately turbid water and ample cover such as vegetation or submerged structures. It tolerates a range of temperatures and can inhabit brackish water in some areas. It is widespread across much of Europe and parts of western Asia and has been introduced to other regions for angling.

Biology: Pikeperch is an ambush predator that feeds mainly on other fish and, to a lesser extent, invertebrates. It is most active during dawn and dusk. Spawning occurs in spring in shallow, vegetated areas; females lay hundreds of thousands of adhesive eggs, which are guarded by males until hatching.

Fisheries and human use: Pikeperch is valued for both sport fishing and consumption, supporting commercial fisheries in some regions. In areas where it has been introduced, it can compete with native species and affect local ecosystems.
