Know When a Sturgeon Catch Must Be Tagged, Registered or Released
A Wisconsin fishing license alone does not authorize an angler to harvest lake sturgeon. Keeping one generally requires the correct sturgeon harvest privilege, immediate tag validation and in-person registration at an approved station.
This guide separates hook-and-line harvest, catch-and-release fishing, Winnebago System spearing and shovelnose sturgeon rules so you can follow the right reporting process.
TIME
Does Every Wisconsin Sturgeon Catch Have to Be Reported?
No general harvest registration is required when a lake sturgeon is lawfully caught and immediately released on water open to sturgeon fishing. However, a harvested lake sturgeon must follow Wisconsin’s tagging and mandatory registration process.
For hook-and-line harvest, Wisconsin DNR states that the carcass tag must be validated immediately after harvest and before the fish is moved. The harvested fish must then be taken to a designated registration station no later than 6 p.m. on the day after it was caught.
Winnebago System spearing uses a different deadline. The successful spearer must accompany the fish to the correct DNR-operated registration station by 2 p.m. on the day it was speared.
Match Your Wisconsin Sturgeon Catch to the Correct Action
The reporting requirement depends on whether the fish is released or harvested, how it was taken and where it was caught.
| Situation | License or tag | Required action | Important deadline |
|---|---|---|---|
| Lawful hook-and-line catch that is immediately released | Appropriate general fishing license; no harvest tag needed solely for release | Handle carefully and return the fish promptly | Release immediately |
| Lake sturgeon kept during an open hook-and-line harvest season | General fishing license plus correct sturgeon hook-and-line harvest privilege | Validate carcass tag immediately, then register the fish in person | By 6 p.m. the day after capture |
| Sturgeon speared on Lake Winnebago | Valid Lake Winnebago sturgeon spearing license | Validate tag and take fish to a Lake Winnebago registration station | By 2 p.m. that day |
| Sturgeon speared on an Upriver Lake | Successful authorization plus Upriver Lakes spearing license | Use an Upriver Lakes registration station | By 2 p.m. that day |
| Accidental sturgeon catch where targeting is not open | A license does not authorize closed-season targeting | Do not keep the fish; minimize handling and release it promptly | Immediately |
| Sturgeon carrying an external research tag | Normal fishing requirements still apply | Record tag number and catch details and follow instructions printed on the tag | Report as soon as practical if requested |
Which Wisconsin Fishing License Is Needed for Sturgeon?
Most residents and nonresidents age 16 or older need an appropriate Wisconsin general fishing license. An angler who plans to harvest a lake sturgeon must also buy the correct sturgeon hook-and-line harvest privilege for the water being fished.
Wisconsin DNR lists separate products for inland hook-and-line sturgeon and Wisconsin–Michigan hook-and-line sturgeon. Select the product that matches the exact water rather than buying a similarly named privilege.
| Sturgeon product | Resident fee | Nonresident fee | Key use |
|---|---|---|---|
| Sturgeon Hook & Line Inland | $20 | $50 | Harvest on eligible inland hook-and-line waters |
| Sturgeon Hook & Line Wisconsin–Michigan | $20 | $50 | Eligible Wisconsin–Michigan boundary-water harvest |
| Lake Winnebago Sturgeon Spearing | $20 | $65 | Lake Winnebago spearing; normally subject to October 31 purchase deadline |
| Upriver Lakes Sturgeon Spearing | $20 | $65 | For anglers authorized through the Upriver Lakes drawing |
| Upriver Lakes Spearing Application | $3 | $3 | Drawing application or preference-point process; deadline is normally August 1 |

Open Wisconsin Go WildWisconsin Lake Sturgeon Seasons for 2026–2027
Wisconsin’s general season table lists the 2026 lake sturgeon hook-and-line harvest season as September 5 through September 30, 2026. Only specified waters support this harvest opportunity, and special or boundary-water rules can differ.
New for the 2026–2027 regulation year, selected Wisconsin rivers and connected waters have an expanded lake sturgeon catch-and-release season. On the listed regional waters, it generally runs from June 6, 2026 through March 7, 2027.
Hook-and-line harvest
September 5–30, 2026 on eligible waters. A harvested lake sturgeon generally must be at least 60 inches and counts as the angler’s one sturgeon for the season.
Expanded release season
June 6, 2026–March 7, 2027 on the specifically listed regional waters. Harvest remains closed outside the authorized harvest period.
Winnebago spearing
The 2026 season opened February 14 and could run for a maximum of 16 days or close earlier when a system harvest cap was met.
Check the official Wisconsin fishing season dates and the 2026–2027 new fishing regulations before planning your trip.
How to Register a Hook-and-Line Lake Sturgeon
The following sequence applies when an eligible angler lawfully harvests a lake sturgeon during an open hook-and-line harvest season.
-
Confirm the fish is legal before keeping it.
Check the species, exact water, open season, minimum length and your unused harvest privilege. -
Validate the carcass tag immediately.
Validate the tag as directed immediately after harvesting the sturgeon and before moving it. -
Keep the validated tag with the fish.
The tag must remain with the sturgeon. It must be physically attached if the license holder leaves the carcass. -
Identify an approved registration station.
Use the DNR’s current season list. Do not assume a station used in a previous year is still operating or has the same hours. -
Protect the fish until the station opens.
Many stations are not open 24 hours. Be prepared to keep a large fish properly iced without altering information needed for registration. -
Present the sturgeon before the deadline.
The harvested fish must reach a designated registration station no later than 6 p.m. on the day after it was caught. -
Allow DNR staff to collect harvest data.
Registration may include length, weight, sex, maturity or biological-sample information used for population management.
Winnebago System Sturgeon Spearing Registration Rules
Do not apply the hook-and-line “next-day” deadline to a Winnebago System spearing harvest. A successful spearer must accompany the fish to a DNR-operated registration station by 2 p.m. on the day it was speared.
Lake Winnebago harvest
A sturgeon speared on Lake Winnebago must be registered at one of the designated Lake Winnebago registration stations.
Upriver Lakes harvest
A fish speared on Lake Poygan, Lake Winneconne or Lake Butte des Morts must be taken to an Upriver Lakes registration station.
Immediate tag validation
The carcass tag must be validated immediately upon harvest by removing the designated validation stub.
Transport visibility
DNR’s 2026 season guidance required harvested sturgeon to be openly exposed and visible while being transported for registration.
What to Do When a Wisconsin Sturgeon Is Released
A sturgeon harvest tag is not needed solely to catch and release lake sturgeon on water open to sturgeon angling. That does not remove the need for a general fishing license or make closed water legal to target.
Keep it wet
Prepare tools before lifting the fish. Minimize air exposure and avoid placing the sturgeon on hot, dry or rough surfaces.
Support the body
Support a large sturgeon horizontally. Never suspend it vertically by the jaw, gills or tail for a long photo session.
Remove hooks safely
Use suitable pliers. If removing a deeply embedded hook would cause more injury, cut the line as close as reasonably possible.
Useful details to record voluntarily
- Date and approximate catch time
- Waterbody and general river section
- Approximate length
- External tag number, color and placement
- Condition of the fish when released
- Clear photo of a research tag when it can be taken without delaying release
Special River and Boundary-Water Sturgeon Rules
Lake sturgeon rules are not uniform across Wisconsin. A dam, state boundary or named river section can change the season, harvest status and license product.
| Water situation | Why it needs extra checking | What to confirm |
|---|---|---|
| Inland harvest waters | Only designated waters provide hook-and-line harvest opportunity | Open dates, 60-inch minimum, season limit and station |
| Wisconsin–Michigan waters | A separate sturgeon privilege is listed | Correct license, river section and state-specific regulation |
| St. Croix River | Rules can change above and below St. Croix Falls Dam | Dam side, date and whether only release is allowed |
| Mississippi River | Rules vary around Red Wing Dam and by bordering jurisdiction | Exact pool or section and state-side requirements |
| Menominee River | Rules differ above and below Grand Rapids Dam | Season, harvest status and WI–MI privilege |
| Expanded 2026 release waters | The new opportunity applies only to specifically listed rivers and connected waters | Named start point, endpoint and inclusive dates |
Use this five-point location check
- Name the exact river, lake or flowage. Avoid relying only on a county or nearby town.
- Find the legal section. Record nearby dams, bridges, tributaries and pool numbers.
- Confirm the species. Lake sturgeon and shovelnose sturgeon do not share one universal rule.
- Match the date and intent. Check whether targeting, release or harvest is authorized.
- Locate the registration station before harvesting. Confirm the current year’s station and operating hours.

Check official fishing regulationsShovelnose Sturgeon Are Governed by Different Rules
Do not use lake sturgeon licensing and reporting instructions automatically for shovelnose sturgeon. Wisconsin DNR lists general inland waters as closed to shovelnose sturgeon fishing, while specified sections of the Wisconsin and Mississippi river systems have separate opportunities.
For the 2026–2027 season, Wisconsin DNR lists a changed shovelnose sturgeon season on the Lower Wisconsin River downstream from Prairie du Sac Dam: July 4, 2026 through March 7, 2027. Other boundary-water dates and exceptions may differ.
Common Wisconsin Sturgeon Reporting Mistakes
Buying only a general fishing license
A general fishing license does not include the privilege to harvest a lake sturgeon. The appropriate sturgeon harvest product is also required.
Validating the tag later
The carcass tag must be validated immediately upon harvest and before the sturgeon is moved.
Treating registration as optional
A lawfully harvested lake sturgeon must be presented at the designated registration station within the applicable deadline.
Using the wrong deadline
Hook-and-line harvest generally uses the 6 p.m. next-day deadline; Winnebago System spearing uses 2 p.m. on the day of harvest.
Assuming stations remain open late
Many hook-and-line registration stations are not open 24/7. Verify hours and prepare to keep the fish iced.
Targeting during a closed season
Planning to release the fish does not legalize intentional sturgeon fishing where or when targeting is closed.
Using last year’s station list
Locations and hours can change. Use the registration-station list published for the current harvest season.
Confusing two sturgeon species
Lake sturgeon and shovelnose sturgeon have different seasons, waters, size rules and harvest requirements.
