1 · What license do you need?
| Angler | Annual fee |
|---|---|
| Resident | verify locally |
| Non-resident | verify locally |
Source: verify locally — see Wisconsin Department of Natural Resources (WI DNR) current license fees and regulations.. Verify the exact product and any one-day or short-term options with the agency.
2 · Size & bag limits
| Species | Min size | Bag limit | Citation |
|---|---|---|---|
| All species | — | verify locally | see Wisconsin Department of Natural Resources (WI DNR) current fishing regulations. |
3 · Required stamps & report cards
License fees and size/bag limits for Wisconsin are pending verification. Each state sets its own resident and nonresident fees and per-species limits — always confirm with Wisconsin Department of Natural Resources (WI DNR) before fishing.

5 · Who to contact
State agency & contact
Licenses, regulations, and stocking are set by the agency below. When FishFig can’t verify a figure, contact them directly.

6 · Work the checklist in this order
Read the sections on this sheet in sequence, because each one can invalidate the one before it. The license comes first: without a current one, nothing else on the sheet matters. The limits come second, and they are statewide defaults. The stamps and report cards come third — a species endorsement or a harvest card can be required on top of the license, and holding the license alone does not satisfy it. The waterbody-specific rules come last, and they win: where a named lake, river section, or zone has its own size, slot, bag, or season rule, that rule replaces the statewide default on this sheet.
Two habits catch most of what a printed sheet cannot. Fill in the water you actually intend to fish before you leave, and check that specific water’s current regulation rather than relying on the statewide line. And photograph or write down the tag, date, and location of anything you keep that may fall under a reporting requirement — the obligation usually attaches to the fish, not to the license, so a fully licensed angler can still be out of compliance for failing to register a catch inside the window.
This sheet is deliberately narrow. It states the fees and statewide limits FishFig can attribute to a Wisconsin Department of Natural Resources (WI DNR) publication, and it names the agency for everything else, rather than printing a number that may already be out of date. In-season closures, emergency orders, drawdowns, and special-regulation waters are published by the agency and are not tracked here.
7 · Limits, reporting and inspection rules tracked for Wisconsin
Every figure below is read from FishFig's verified Wisconsin data layer and names its source. Where a value could not be verified it reads "verify locally" rather than a placeholder number.
Size and bag limits tracked for Wisconsin
Wisconsin has 13 statewide limits resolved in this tool — Bluegill, Brook Trout, Brown Trout, Channel Catfish, Crappie, Flathead Catfish, Largemouth Bass and Muskellunge (Muskie), among 13 in the tracked set. Each entry below carries the agency citation it came from.
Bluegill: bag 25 (panfish total: bluegill, pumpkinseed, yellow perch, crappie); season Year-round; Many lakes use 10-fish limits or 5-fish species sublimits.. Citation: Wisconsin DNR — 2026–27 Wisconsin Fishing Regulations (Hook & Line; Wis. Adm. Code NR 20).
Brook Trout: bag 5 streams (3 on some sections) / 3 lakes; season Streams: 1st Sat May – Oct 15; lakes open periods. Citation: Wisconsin DNR — 2026–27 Wisconsin Fishing Regulations (Hook & Line; Wis. Adm. Code NR 20).
Brown Trout: bag 5 streams (3 on some sections) / 3 lakes; season Streams: 1st Sat May – Oct 15; lakes open periods. Citation: Wisconsin DNR — 2026–27 Wisconsin Fishing Regulations (Hook & Line; Wis. Adm. Code NR 20).
Channel Catfish: bag 25 total (only 1 flathead from Lake Winnebago System); season Year-round. Citation: Wisconsin DNR — 2026–27 Wisconsin Fishing Regulations (Hook & Line; Wis. Adm. Code NR 20).
Crappie: bag 25 (panfish total); season Year-round; Many lakes use 10-fish limits or 5-fish species sublimits.. Citation: Wisconsin DNR — 2026–27 Wisconsin Fishing Regulations (Hook & Line; Wis. Adm. Code NR 20).
Flathead Catfish: bag Within 25 total catfish (Lake Winnebago System: 1, 30 in min, 36–42 in protected); season Year-round. Citation: Wisconsin DNR — 2026–27 Wisconsin Fishing Regulations (Hook & Line; Wis. Adm. Code NR 20).
These are statewide general rules only. Slot limits, special-regulation waters, catch-and-release stretches, and zone-by-zone seasons override them — and a general rule that is absent from this list is not the same as no restriction. Confirm the rule for the exact water you are fishing with Wisconsin Department of Natural Resources (WI DNR) before keeping a fish.
Mandatory harvest reporting in Wisconsin
Wisconsin requires mandatory harvest reporting or registration for specific species. The tracked rule set covers Lake Sturgeon.
Reporting window: Hook-and-line harvest season Sept 5 - Sept 30, 2026 (authorized waters); C&R season on designated waters June 6, 2026 - Mar 7, 2027.. How to report: Anglers intending to keep a sturgeon must purchase a harvest tag ($20 resident / $50 nonresident); validate carcass tag immediately upon harvest. A harvested fish must be registered at a designated registration station no later than 6 p.m. the day after it was caught. Catch-and-release does not require a tag on waters open to sturgeon fishing. Harvest tag via Go Wild; register at DNR station by 6 p.m. next day.. Citation: Wisconsin Department of Natural Resources - Lake Sturgeon Hook and Line Season (https://dnr.wisconsin.gov/topic/Fishing/sturgeon/SturgeonInlandFishery)
A reporting requirement usually attaches to the fish, not the license: you can be fully licensed and still be out of compliance for failing to register a tagged or sensitive species within the stated window. Record the tag number and the date before you leave the water.
Boat inspection and invasive species rules in Wisconsin
No statewide AIS stamp or universal inspection mandate for Wisconsin is tracked here, so this section states the baseline rule that applies everywhere rather than a state-specific one.
Wisconsin requires Clean, Drain, Dry: all watercraft must be drained (live wells, bilge, bait buckets) and aquatic invasive species must not be transported; no statewide AIS decal or pre-launch inspection is required. Verify current AIS rules with Wisconsin DNR before launching.
The baseline is not optional in practice. Water, mud, and plant fragments carried on a trailer or in a livewell are the main transport path for zebra mussels, Eurasian watermilfoil, and spiny water flea, and an inspection station can turn you around at the ramp. Clean, drain, and dry the hull, trailer, anchors, waders, and any livewell before you leave the water, and again before you launch somewhere new.

Free fishing days in Wisconsin
Reported license-free dates for 2026: January 17–18 & June 6–7, 2026. Most states waive the license only, not the rules — size and bag limits, gear restrictions, seasons, and any required report card still apply, and some states still require a free or zero-cost license to be issued before you fish.
Reported for 2026 by public aggregators and may not match the official state schedule. Always confirm the current year’s dates and any species/stamp exceptions with the agency before planning.

Always confirm current fees, seasons, and closures with Wisconsin Department of Natural Resources (WI DNR) before fishing. This checklist is a planning aid and may not reflect in-season changes.
