State Fish Of Wisconsin

The Fish “Muskellunge” Is The State Fish Of Wisconsin. Wisconsin designated the muskellunge (Esox masquinongy Mitchell) or “muskie” as the official Wisconsin State Fish in 1955. The Muskellunge was recommended as the state fish because of the dominance of Wisconsin muskies in competition over the years. The trout fish was also suggested as the state fish but failed to pass because it wasn’t nearly as popular as the musky. 

The muskellunge looks and behaves like a huge northern pike. State Fish Of Wisconsin has an elongated body, a flat head, and its fins are set far back in its body. Muskellunge are light silver, brown, or green in color with dark vertical stripes or spots on the sides and white bellies. Females are longer and heavier than males. Wisconsin State Fish “Muskies” are highly prized by Midwestern anglers for their massive size, the difficulty of catching them, and their fighting ability. To feed, they lurk behind shaded spots or in weed beds and then explode forward to grab passing prey, which they then swallow whole.
