Montana Fishing Compliance Checklist

1 · What license do you need?
| Angler | Annual fee |
|---|---|
| Resident | verify locally |
| Non-resident | verify locally |
Source: verify locally — see Montana Fish, Wildlife & Parks (FWP) 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 Montana Fish, Wildlife & Parks (FWP) current fishing regulations. |
3 · Required stamps & report cards
License fees and size/bag limits for Montana are pending verification. Each state sets its own resident and nonresident fees and per-species limits — always confirm with Montana Fish, Wildlife & Parks (FWP) 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.
Montana Fish, Wildlife & Parks (FWP)
FishFig is an independent guide and is not affiliated with Montana Fish, Wildlife & Parks (FWP). Verify every figure with the agency before purchasing a license, keeping fish, or relying on stocking data.
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 Montana Fish, Wildlife & Parks (FWP) 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 Montana
Every figure below is read from FishFig's verified Montana 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 Montana
Montana has 13 statewide limits resolved in this tool — Bluegill, Brook Trout, Brown Trout, Common Carp, Channel Catfish, Crappie, Largemouth Bass and Muskellunge (Muskie), among 13 in the tracked set. Each entry below carries the agency citation it came from.
Bluegill: bag No limit (not listed in standard limits); season Year-round. Citation: Montana Fish, Wildlife & Parks — 2026 Montana Fishing Regulations (District Standard Limits).
Brook Trout: bag 20 daily / 20 possession (Central District); 10 (Western District); season Year-round; Listed separately from the combined trout limit.. Citation: Montana Fish, Wildlife & Parks — 2026 Montana Fishing Regulations (District Standard Limits).
Brown Trout: bag 5 daily / 10 possession (lakes); 5 daily / 10 possession (rivers, only 1 over 18 in); season Year-round (lakes); Western District rivers 3rd Sat May – Nov 30; Central/Eastern rivers year-round. Citation: Montana Fish, Wildlife & Parks — 2026 Montana Fishing Regulations (District Standard Limits).
Common Carp: bag No limit; season Year-round; Species not listed in the standard limits have no limit.. Citation: Montana Fish, Wildlife & Parks — 2026 Montana Fishing Regulations (District Standard Limits).
Channel Catfish: bag 10 daily / 10 possession; season Year-round. Citation: Montana Fish, Wildlife & Parks — 2026 Montana Fishing Regulations (District Standard Limits).
Crappie: bag 15 daily / 30 possession; season Year-round. Citation: Montana Fish, Wildlife & Parks — 2026 Montana Fishing Regulations (District Standard Limits).
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 Montana Fish, Wildlife & Parks (FWP) before keeping a fish.
Mandatory harvest reporting in Montana
Montana requires mandatory harvest reporting or registration for specific species. The tracked rule set covers paddlefish.
Reporting window: White/blue tag: report within 48 hours. Yellow/green tag: report by 9 p.m. day of harvest or before transport. How to report: Harvest hotline 877-FWP-WILD or 406-444-0356, or online at myfwp.mt.gov. Tag must be validated immediately upon harvest.. Citation: Montana FWP — 2026 Paddlefish Regulations
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 Montana
Montana has a tracked aquatic-invasive-species requirement for boaters: Vessel AIS Prevention Pass.
Fee or cost: $30 motorized / $10 nonmotorized (nonresident); resident angler AIS pass $2 / $7.50.
Inspection: Mandatory inspection before launching (stop at all open stations when entering the state).
Montana requires an AIS Prevention Pass for vessels. Motorized/nonmotorized nonresident passes are $30/$10; resident anglers pay $2 (or $7.50 with certain licenses). Vessels must stop at inspection stations when entering MT.

Free fishing days in Montana
Reported license-free dates for 2026: May 9–10 & June 20–21, 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 Montana Fish, Wildlife & Parks (FWP) before fishing. This checklist is a planning aid and may not reflect in-season changes.
