The Wisconsin Natural Resources Board approved a permanent rule changing possession and bag limits for round gobies and other detrimental fish species. The rule takes effect November 1, 2026.
Why it matters
Angler harvest and reporting of all gobies taken is essential for tracking the spread of this invasive species across the state. The rule aims to encourage removal of detrimental species from Wisconsin waters.
The rule sets no possession limit on gobies and ruffe from any Wisconsin waterbody, and white perch possession is also unlimited. Harvested gobies, ruffe, and inland white perch must be immediately eviscerated, decapitated, or have gills removed.

Anglers across Wisconsin can keep gobies and ruffe without limit starting November 1, 2026. Anyone harvesting these fish or inland white perch must eviscerate, decapitate, or remove gills immediately after catching them.
The takeaway
Anglers who catch round gobies or ruffe in Wisconsin waters can keep as many as they take starting November 1, 2026. Processing them immediately after capture is required under the new rule.
