Fisheries biologists
Fishing Wisconsin
Fisheries biologists have management responsibilities by counties. In some cases, counties may be further subdivided into management areas. Additionally, you can find Great Lakes, Treaty and U.S. Forest Service responsibilities under other management areas. Use the map to select the desired county or scroll down to find the county or region. Once you have found the biologist you are looking for, click on their name to view their phone number, address, email address and other contact information.
