Idaho Fishing Compliance Checklist

1 · What license do you need?
| Angler | Annual fee |
|---|---|
| Resident | verify locally |
| Non-resident | verify locally |
Source: verify locally — see Idaho Department of Fish and Game (IDFG) 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 Idaho Department of Fish and Game (IDFG) current fishing regulations. |
3 · Required stamps & report cards
License fees and size/bag limits for Idaho are pending verification. Each state sets its own resident and nonresident fees and per-species limits — always confirm with Idaho Department of Fish and Game (IDFG) 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.
Idaho Department of Fish and Game (IDFG)
FishFig is an independent guide and is not affiliated with Idaho Department of Fish and Game (IDFG). 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 Idaho Department of Fish and Game (IDFG) 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 Idaho
Every figure below is read from FishFig's verified Idaho 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 Idaho
Idaho has 10 statewide limits resolved in this tool — Brook Trout, Brown Trout, Common Carp, Crappie, Largemouth Bass, Muskellunge (Muskie), Northern Pike and Rainbow Trout, among 10 in the tracked set. Each entry below carries the agency citation it came from.
Brook Trout: bag 25; season Year-round; Harvest encouraged on many waters.. Citation: Idaho Department of Fish and Game — 2025–2027 Idaho Fishing Rules (Regional daily bag limits).
Brown Trout: bag 6 (lakes); 2 (rivers); combined with trout; season Year-round. Citation: Idaho Department of Fish and Game — 2025–2027 Idaho Fishing Rules (Regional daily bag limits).
Common Carp: bag No limit; season Year-round. Citation: Idaho Department of Fish and Game — 2025–2027 Idaho Fishing Rules (Regional daily bag limits).
Crappie: bag 25; season Year-round. Citation: Idaho Department of Fish and Game — 2025–2027 Idaho Fishing Rules (Regional daily bag limits).
Largemouth Bass: bag 6 (combined with smallmouth; lakes/reservoirs); season Year-round; Many rivers/streams have no bag limit; some regions impose a 12 in minimum.. Citation: Idaho Department of Fish and Game — 2025–2027 Idaho Fishing Rules (Regional daily bag limits).
Muskellunge (Muskie): minimum length 40 in; bag 2 (tiger muskie); season Year-round; Southwest Region standard; none under 40 in.. Citation: Idaho Department of Fish and Game — 2025–2027 Idaho Fishing Rules (Regional daily bag 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 Idaho Department of Fish and Game (IDFG) before keeping a fish.
Mandatory harvest reporting in Idaho
Idaho requires mandatory harvest reporting or registration for specific species. The tracked rule set covers salmon/steelhead.
Reporting window: Electronically validate (e-tag) immediately upon harvest. How to report: Salmon/Steelhead permit must be e-tagged in the GoOutdoorsIdaho app immediately upon landing a fish. Citation: IDFG — Salmon/Steelhead Electronic Validation
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 Idaho
Idaho has a tracked aquatic-invasive-species requirement for boaters: Invasive Species Fund (ISF) sticker.
Any motorized or non-motorized boat operating in Idaho must display an ISF sticker; required for both residents and visitors.
Citation: Idaho Department of Fish & Game — Invasive Species Fund sticker requirement.
Free fishing days in Idaho
Reported license-free dates for 2026: June 13, 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.
