Michigan has specific catch reporting requirements that every angler should know. While most species don’t require any reporting, lake sturgeon and muskellunge harvests must be reported within 24 hours — and failing to report is a citable offense. The DNR also encourages voluntary reporting for tagged fish through its Eyes in the Field program.
This guide covers every reporting requirement for 2026.

Black Lake Sturgeon Season — Special Rules
The Black Lake sturgeon season is Michigan’s most unique fishing event — a limited, closely managed harvest of lake sturgeon in the state’s premier sturgeon fishery.
| Detail | Information |
|---|---|
| Registration | Required in advance at michigan.gov/dnrlicenses |
| License requirement | Valid Michigan fishing license (age 17+) |
| Reporting | Immediate on-site registration with DNR personnel |
| Season length | Typically 1-3 days (ends when quota is met) |
| Quota | Limited annual harvest set by DNR |
How Black Lake Reporting Works
- Pre-register online before the season opens
- Fish during the designated season (dates announced annually by DNR)
- Report immediately when you harvest a sturgeon — DNR staff are on-site
- Season closes when the harvest quota is reached, often within hours
Voluntary Catch Reporting
Tagged Fish — Eyes in the Field
Michigan stocks millions of fish annually, and many are fin-clipped or tagged. If you catch a tagged or marked fish:
| Detail | Information |
|---|---|
| Report at | michigan.gov/EyesInTheField |
| Reward | Some tags carry monetary rewards |
| Information needed | Tag number, species, location, date, length |
| Required? | Voluntary — but strongly encouraged |
Why Report Tagged Fish?
- Helps the DNR track fish movement, growth rates, and survival
- Improves stocking programs by measuring effectiveness
- May earn you money — some tags have cash rewards
- Supports science behind regulation setting
Types of Tags You May Find
| Tag Type | Description | What to Do |
|---|---|---|
| Jaw tag | Metal tag on jaw or gill plate | Record number, report online |
| Fin clip | Missing adipose or other fin | Note which fin, report online |
| Floy tag | Plastic anchor tag below dorsal fin | Record number and color, report online |
| PIT tag | Internal electronic tag (not visible) | No action needed unless at a sampling station |
What Happens If You Don’t Report
Mandatory Species (Sturgeon/Muskie)
| Consequence | Details |
|---|---|
| Classification | Misdemeanor |
| Fine | Up to $500 |
| Additional penalties | Possible license revocation |
| Criminal record | Yes — upon conviction |
Failure to report a harvested sturgeon or muskellunge within 24 hours is treated as a regulation violation — the same as exceeding bag limits.
Voluntary Species
No penalty for not reporting tagged fish. But the data is valuable, and you might miss out on a reward.
