Location: Manitowoc WI | I received this email from a fish biolgist in wisconsin. Here are the facts. Feel free to email him with any questions, out tax dollars go to quality answers like these. Thanks for viewing.

As you can see from this graph, walleye from the Fox River (solid line) and Sturgeon Bay (dashes) hit 28" or 711 mm on average at age 10. Certainly some fish reach 28" a year or two earlier and some a few years later. Ageing studies from walleye on the Fox or Sturgeon Bay seem to indicate that by scale ages walleye rarely live longer than 15 years. In southern Green Bay growth is very fast because of warm water temperatures and abundant food, but as you move north into far northern Green Bay I believe growth rates slow.
