The walleye—also known as the yellow pike or pike-perch is a widespread freshwater species native to lakes and rivers across Europe and North America. They have been introduced into additional freshwater systems over time, expanding their natural range. These fish are easy to recognize by their distinctive, outward-facing eyes, which seem to stare at a “wall“—a feature that gives them their name. Their eyes are specially adapted for low-light environments, making walleye more active in deeper or murkier waters. Their bodies are marked with golden scales and olive-green patches, and they feature spiny dorsal and anal fins.

Walleye are typically found near the bottom, often around drop-offs, submerged structures, or deeper areas during daylight. During the breeding season in spring, walleye exhibit notably bold behavior, fearlessly defending their nests from intruders. Males guard the nesting site, ensuring the safety of fertilized eggs by chasing away other fish and potential threats. Their calm, precise movements and reflective eyes make them a memorable sight for divers exploring freshwater dive sites. Want to go diving with the walleye?
