Musky Fishing Opens Saturday News | May 19, 2025 | 0 | by Morgan McCarthy The northern zone musky fishing season will start Saturday in Wisconsin. Anglers will be allowed to target musky fish on open water starting May 24 until the end of 2025. Anglers can expect fish in most waters to be done spawning and ready to feed at the start of the season due to the warmer weather. Musky will likely be active in shallow vegetated bays, channels and on points just adjacent to shallow bays during the early part of the season.
