Blue walleye refers to a species of freshwater fish known scientifically as Sander vitreus glaucus or Stizostedion vitreum glaucum. It is a subspecies of the walleye fish (Sander vitreus) and is characterized by its distinct bluish coloration. The blue walleye is primarily found in the Great Lakes region of North America, particularly in Lake Erie and Lake Huron.
This unique subspecies exhibits a range of color variations, typically consisting of a predominantly bluish hue on its upper body, which can appear lighter or darker depending on the individual fish. The blue coloration provides camouflage in the deep, open waters where it resides. Its underbelly is usually a lighter shade, transitioning to white.
Blue walleye share many physical traits with their walleye counterparts, including an elongated body with a spiny dorsal fin and sharp teeth. They are known for their excellent sight and low-light vision, which aids them in hunting prey in murky waters. Blue walleye are piscivorous, meaning they primarily feed on smaller fish such as yellow perch, alewives, and other small aquatic organisms.
Due to overfishing and habitat loss, blue walleye populations have experienced a significant decline in recent years. Conservation efforts are underway to restore their numbers and protect their natural habitats. These initiatives focus on monitoring and regulating fishing practices, restoring degraded habitats, and increasing public awareness about the importance of preserving biodiversity.
The term "blue walleye" does not have a specific etymology as it is a combination of two words: "blue" and "walleye".
"Blue" refers to the color of the fish, specifically a bluish hue found in walleye. It is worth noting that the term "blue walleye" may vary in usage depending on the region and dialect, as walleye can also appear greenish or yellowish.
"Walleye" is a common name for a species of fish from the perch family (Percidae), also known scientifically as Sander vitreus. The name "walleye" refers to the fish's unique eye placement, with their eyes situated on the sides of their heads, seemingly looking "outward" or "sideways". This gives the impression that they are wall-eyed or having eyes which point towards a wall.
