Illinois Commercial Fishing License Device Tags & IDNR Contacts
This upgraded guide covers the full commercial-fishing workflow: who needs a commercial license, why a sport license is also required, how commercial device tags work, which waters are open, what gear limits apply, and which IDNR office to contact.
Commercial fishing is a compliance stack, not one checkout button. Before you set a net, line, seine, trap or watercraft device, use this page to check license type, tag placement, water restrictions, reporting, dealer rules and practical field records.
Audit fixes added in this version: the previous draft was useful but still missed several high-value commercial details. This rebuilt version adds the official commercial-device definition, watercraft-as-primary-collection-device warning, exact tag placement rules, gear-check intervals, open-water decision logic, commercial species and size-limit notes, detailed mesh/gear rules, mussel/crayfish sections, dealer/receipt/container records, landowner permission, suspension risk, and updated monthly reporting guidance.
Important correction: the record section now reflects the current iFish Illinois guidance that monthly commercial reports are due by the 10th of each month effective January 1, 2027, and reports must be sent even when there was no harvest or purchase activity. This avoids relying on older “January 31 only” or “5th of month” summaries.
Use this page as a field checklist, not legal advice. Commercial operators should verify the official links before buying, renewing, setting gear, selling catch, or changing waters.
Fast answer: an Illinois commercial fisherman is an individual using commercial fishing devices to take aquatic life, except mussels, protected by the Fish and Aquatic Life Code. Commercial fishermen must have a commercial fishing license and must also obtain a sport fishing license.
Assistants: individuals assisting a licensed commercial fisherman must have a commercial fishing license unless they are under direct supervision of, and aboard the same watercraft as, the licensed commercial fisherman. An assistant must first obtain a sport fishing license.
Device tags: every active commercial device must carry the current year’s gear tag and the licensee’s name and address. Absence of required tagging can be treated as evidence the device is illegally used and may lead to confiscation.

What Counts as a Commercial Fishing Device in Illinois
This article is stronger now because it defines the activity. If your device is commercial, a regular fishing license is not enough.
Line devices
Buoyed gangings, set gangings, bank pole and line, throw line, and trot line having more than 50 hooks are commercial-device examples.
Net devices
Seine, pocket seine, otter trawl, dip net, throw net, gill net, trammel net, basket trap, hoop net, wing net, pound net and trap net are listed commercial devices.
Watercraft device
A watercraft used as a primary collection device is also a commercial device. A person using watercraft as a primary collection device must first obtain a commercial watercraft device tag.
Department-added devices
Illinois law also covers any other device considered commercial by the Department when used to take protected aquatic life, except mussels.
Mussels are separate
The ordinary commercial fishing license device definition excludes mussels. Commercial musseling uses its own license and method rules.
Plain-English test
If the gear is beyond normal sport fishing, or if it is used for commercial harvest, stop and check commercial license, tag, water, gear and reporting rules first.
Commercial Fishing License vs Sport Fishing License Do Not Mix These Up
This is the most important license stack in the article.
| Situation | Likely license need | Plain-English warning |
|---|---|---|
| Using commercial devices to take aquatic life, except mussels | Commercial fishing license + sport fishing license | Commercial devices trigger commercial licensing. Do not rely on regular sport fishing credentials. |
| Assisting from the same boat under direct supervision | Narrow exception may apply to commercial license; sport license still matters | If not aboard the same watercraft and directly supervised, assume separate commercial licensing may be needed. |
| Using regular sport fishing gear for personal recreation | Sport fishing license | Do not sell sport-caught fish as if you are commercial. |
| Resident commercial fisherman | Resident commercial product only if one-year resident definition is met | Commercial residency is stricter than casual “I live here now” thinking. |
| Commercial mussel harvest | Commercial mussel license path | Mussel methods, seasons, assistants and dealer rules are separate. |
| Aquaculture, dealer, minnow, roe, wholesale or retail activity | Additional commercial license may be required | Harvest license and sale/dealer license are different concepts. |
How to Buy the Correct Illinois Commercial Fishing License Step by Step
Buying first and checking legality later is the wrong order. Use this workflow.
Define the commercial activity
Write down whether you are harvesting fish, harvesting roe-bearing species, dealing aquatic life, selling retail, selling wholesale, selling minnows, harvesting mussels, transporting fish, or operating aquaculture.
Confirm resident status
Resident commercial fishermen must have actually resided in Illinois for one year immediately preceding application and must not claim residency for commercial fishing in another state or country.
Check personal name vs business name
If the license needs to be issued under a business name, call IDNR at 217-785-3423 or 217-782-2965 to set up a customer number before using online sales.
Buy the commercial license and sport license
Commercial fishermen are required to hold the commercial fishing license and a sport fishing license. Helpers also need to check the sport-license requirement.
Add device tags and special tags
Buy the correct current-year device tags. If using watercraft as a primary collection device, check the commercial watercraft device tag requirement.
Verify water, gear and distance rules
Confirm the water is open, the gear is legal there, the method is allowed, and you are not within prohibited distances of spillways, fishways, locks or dams.
Prepare recordkeeping before harvest
Set up your monthly catch log, buyer log, receipt file, tag list, gear-check schedule and report calendar before the first set.

Commercial Device Tags Where the Tag Goes
Tag placement is one of the easiest fixes and one of the easiest violations to spot.
Seines
Attach tag or tags to the brail or to the leader line adjoining the brail on either end of the seine.
All nets
Attach the tag to the rear hoop, tail line, or tail pole.
Other devices
Place the tag where it is exposed to public view. Hidden tags defeat the rule.
Missing tag risk
Untagged devices can be treated as illegally used and may be confiscated or disposed of as directed by IDNR.
Name and address
Gear must show the owner/licensee name and address. Use durable, readable marking that survives water, mud and abrasion.
Field proof habit
Photograph every tagged device before setting it. Store photos by date, tag number, water and river mile/landmark.
Gear Check Intervals Do Not Let Legal Gear Become Illegal
A properly licensed and tagged device can still become illegal if it is not checked and emptied on time.
| Gear type | Open-water check interval | Ice-cover interval | Practical warning |
|---|---|---|---|
| Hoop nets and basket traps | Attend at least once every 72 hours | Attend at least once every 20 days | Set calendar reminders for each gear line. |
| Trammel and gill nets | Immediate supervision Oct 1–Apr 30 during daylight/open water; at least every 24 hours May 1–Sep 30 | Attend at least every 96 hours | When taking or possessing roe-bearing species, nets must be attended from 10 a.m. to 4 p.m. |
| Trotlines and other hook-and-line devices | Check at least every 24 hours | Check applicable ice/gear rules before use | Unattended hook gear creates a high enforcement risk. |
| Seines and trammel/gill nets fished by driving or drifting | Constantly attended | Not a set-and-leave method | Moving gear needs active operation. |
| Gear with dead or moribund fish from failure to check/empty | Can be considered illegal device | Same risk under ice | This is why written check logs matter. |
Waters Open to Illinois Commercial Fishing Decision Guide
Commercial fishing is open only in listed waters and can be restricted by refuge, permit, waterfowl, tributary, lock/dam and seasonal rules.
| Water / area | Commercial status summary | Important exclusion or action |
|---|---|---|
| Lake Michigan | Limited-entry commercial fishery. | Call Lake Michigan Program: 847-294-4134. |
| Mississippi River and connected public backwaters | Generally listed as open during normal flows/stages. | USFWS refuge waters and named bays/management areas may be excluded or permit-only. |
| Illinois River and connected public backwaters | Listed from Route 89 highway bridge downstream. | State fish/wildlife areas, duck-season closures and refuge waters can change access. |
| Wabash River | Listed as open. | Roe, sturgeon and size/season rules matter. |
| Little Wabash, Skillet Fork, Embarras, Sangamon, Kaskaskia, Big Muddy, Cache, Saline, Ohio River | Specific listed segments are open. | Check exact bridge, route, dam, tributary and segment descriptions before setting gear. |
| Streams, ditches or tributaries connected to listed backwaters | Commercial fishing is not generally permitted under the backwater rule. | Do not assume connected water means open water. |
| Other lakes and streams | May be opened by special season or contract with IDNR. | Get written authority or official confirmation first. |
Commercial Species, Protected Species and Size Rules Quick Reference
The previous draft did not cover enough species and size-rule intent. This version adds the practical checks operators need before sorting catch.
Commercial species examples
Commercially available species include common carp, buffalo, freshwater drum, catfishes, carpsuckers, suckers, certain redhorses, mooneye, goldeye, gar except alligator gar, gizzard shad, minnows, goldfish and invasive carp species.
Protected species
State or federally endangered or threatened aquatic life cannot be taken or possessed. Accidental protected-species captures should be reported through IDNR/Conservation Police channels.
Catfish size note
Channel, flathead, blue and white catfish have commercial size rules, with different Wabash/Ohio River rules. Measure before keeping.
Roe species
Paddlefish, shovelnose sturgeon and bowfin have roe-related license, season, size and handling rules. Do not treat them as ordinary commercial catch.
Dressed fish
“Dressed” means the head has been removed. Dressed and undressed measurements can differ, so record form and measurement method.
Sort immediately
After complete retrieval, non-compliant fish and illegal species should be removed and returned without unnecessary injury unless unsafe, in which case move to a nearby shore area as allowed.
Gear Specs and Use Limits Mesh, Distance, Blocking and Cribs
Gear legality is more than buying tags. Method, mesh, length, distance, visibility and storage rules all matter.
| Gear / rule | Practical requirement | Common mistake |
|---|---|---|
| 300-yard distance | Commercial devices may not be used within 300 yards above or below any spillway, fishway, lock or dam. | Setting close to structures because the water looks productive. |
| Blocking watercourse | Devices cannot block more than half the stream unless visibility and fluorescent-buoy conditions are met. | Ignoring boater safety and obstruction rules. |
| Basket traps | Must be wood or plastic slats with unobstructed rear openings of at least 1.5 inches square. | Using wire traps. |
| Trot lines | Hooks must be spaced at least 24 inches apart. | Using closer hook spacing or drawing lines through water to snag. |
| Hoop nets | Mesh must be not less than 1 inch bar measure; wings/leads must meet twine rules. | Mixing old gear into current operation without measuring. |
| Dip nets | Mesh must be at least 1.5 inches bar measure and no more than 15 feet square or in diameter. | Using oversized or wrong-mesh dip nets. |
| Trammel and gill nets | Trammel mesh generally at least 2 inches; gill net mesh generally at least 3 inches, with Ohio River rules requiring 4 inches. | Using wrong water or wrong mesh for river. |
| Seines | Length, mesh, backstop and water-depth rules depend on seine length. | Using a long seine without required backstop/depth setup. |
| Cribs, live boxes, holding nets | Must be plainly labeled with owner name and address. | Using commercial fishing devices as cribs. |
| Under ice | Holes must be clearly marked; trammel nets must be at least 100 yards from natural ice openings. | Failing to mark ice holes visibly. |
Commercial Roe Harvester Rules Extra License, Extra Risk
Roe-bearing commercial harvest is a high-compliance area. Treat it separately from ordinary commercial fish harvest.
Roe authority first
Commercial harvest of paddlefish, shovelnose sturgeon or bowfin can require a commercial roe harvester permit/license in addition to commercial fishing licensing.
Do not kill to check eggs
Commercial roe harvesters may use a 10 or 12 gauge needle to examine roe-bearing species for eggs. Do not kill fish simply to check for eggs.
October 1 timing trap
Do not set tackle before 10:00 a.m. on October 1 on the Mississippi and Wabash Rivers when operating under commercial roe harvest rules.
Paddlefish size
Paddlefish size limits differ by river and are measured from the front of the eye to the fork of the tail.
Shovelnose sturgeon
Commercial harvest is limited to specified rivers and seasons, with minimum and slot-size rules depending on the river.
Roe records
Track processing type, roe weight and price per pound from day one. Do not reconstruct roe reports later.
Mussels, Crayfish, Minnows and Aquaculture Separate Paths
Commercial fishing, commercial musseling, commercial crayfish, minnow dealing and aquaculture are not the same license path.
| Activity | Key point | Practical warning |
|---|---|---|
| Commercial musseling | Commercial musselors need a commercial mussel license; assistants also need a commercial mussel license. | Mussels may be taken only by legal methods such as crowfoot bars or hand picking under applicable rules. |
| Mussel dealer activity | Resident and non-resident mussel dealer licenses are separate. | Possessing shell after allowed timing can trigger dealer-license issues. |
| Commercial crayfish harvest | Seines are the only commercial devices legal to commercially harvest crayfish in open crayfish waters. | Seine depth, bag height and mesh limits apply. |
| Approved live crayfish species | White River, Papershell, Northern and Devil Crayfish are the listed approved live bait/food species. | Do not sell or transport other live crayfish as if they are automatically legal. |
| Minnow dealer activity | Retail, wholesale and interstate minnow dealer licenses are separate products. | Dealer activity is not covered by a basic commercial fishing license alone. |
| Aquaculture | Aquaculture permit covers breeding, hatching, propagating or raising aquatic life under IDNR rules. | Approval may be required before purchase; do not confuse farm-raised stock with wild commercial harvest. |
Selling Catch, Dealer Licenses and Records Paperwork Is Compliance
Commercial fishing is not complete when the fish leaves the water. Records, receipts, buyer details, container tags and reports are part of the operation.
Commercial fisherman records
- Keep accurate monthly records throughout the year.
- Record species and number of pounds taken.
- Record gear type used.
- Record location taken.
- For roe, record processing type, weight in pounds and price per pound.
- Make records available to IDNR for inspection.
Monthly reporting update
- Monthly reports are due by the 10th of each month effective January 1, 2027.
- Report categories include fish/crayfish harvest, special-use permit harvest, roe harvest, roe dealer, mussel harvest and mussel dealer.
- Reports must be sent even if no fish/crayfish, roe-bearing fish or mussels were harvested.
- Reports must also be sent even if no roe, mussels or relic shells were purchased.
- Failure to submit required reports can be a violation and can affect the next license year.
Dealer and sale rules
- A licensed commercial fisherman may sell legally taken commercial species to a resident licensed wholesale aquatic life dealer without additional licenses.
- Retail market sales or live fish for stocking can require a Resident Retail Aquatic Life Dealer License.
- Wholesale market or selling/shipping to commercial institutions can require a Resident Wholesale Aquatic Life Dealer License.
- Non-resident sales or shipments can require a Non-Resident Aquatic Life Dealer License.

Real Commercial Fishing Tips That Prevent Expensive Problems
These are field habits that make the article more useful than a basic licensing page.
Before buying
- Call IDNR before buying if the license needs to be in a business name.
- Confirm one-year commercial residency before choosing resident products.
- Buy the sport fishing license at the same time so the stack is complete.
- Check whether your activity is harvest, dealer, roe, mussel, minnow, aquaculture or transport.
- Save PDFs and screenshots of licenses, tags and receipts before leaving for the river.
Before setting gear
- Photograph each tagged device before setting it.
- Log GPS point, river mile or landmark for every set.
- Mark the legal check deadline immediately after setting.
- Carry spare durable tag fasteners that do not rust or break easily.
- Do not set close to locks, dams, spillways or fishways and argue later.
During harvest
- Sort illegal or non-compliant fish immediately after complete retrieval.
- Do not use commercial gear as a holding crib.
- Keep buoy visibility high when gear could affect boaters.
- Do not let employees lift gear for more than one licensee in one day where that rule applies.
- Use a scale and record system that can survive inspection, not rough estimates.
After harvest
- Record species, pounds, gear and location the same day.
- Keep dealer receipts and duplicate copies organized by date.
- Label transport containers before moving aquatic life.
- Put monthly report deadlines on a calendar with reminders.
- Do not wait until renewal season to discover missing reports block the next license.

Find vendorIllinois Commercial Fishing License FAQ
Do I need a commercial fishing license in Illinois?
Yes, if you use commercial fishing devices to take aquatic life, except mussels, protected by the Fish and Aquatic Life Code. Commercial fishermen also need a sport fishing license.
Do commercial fishermen also need a sport fishing license?
Yes. Illinois commercial fishermen are required to obtain a sport fishing license in addition to their commercial fishing license.
Do helpers need their own commercial fishing license?
Assistants generally need a commercial fishing license unless they are under direct supervision of and aboard the same watercraft as the licensed commercial fisherman. Assistants must first obtain a sport fishing license.
Where do commercial fishing tags go?
Seine tags go on the brail or leader line adjoining the brail on either end. Net tags go on the rear hoop, tail line or tail pole. Other device tags must be exposed to public view.
What happens if commercial gear is not tagged?
Missing tags can be treated as evidence that the device is illegally used, and the gear may be confiscated or disposed of as directed by IDNR.
Can I buy a commercial fishing license under a business name?
Yes, but IDNR says a business-name license requires customer number setup before online sales. Call 217-785-3423 or 217-782-2965 before buying.
How often must commercial fishing gear be checked?
Hoop nets and basket traps must be attended at least once every 72 hours during open water. Trammel and gill net timing depends on date, daylight/open water, roe activity and ice cover. Trotlines and other hook-and-line devices must be checked at least every 24 hours.
When are monthly commercial reports due?
Monthly reports are due by the 10th of each month effective January 1, 2027. Reports must be sent even when there was no harvest or purchase activity for the relevant category.
Can I commercially fish Lake Michigan?
Lake Michigan commercial fishing is limited-entry. Contact the Division of Fisheries Lake Michigan Program at 847-294-4134 before assuming ordinary commercial licensing is enough.
Can commercial fishermen sell fish directly?
Licensed commercial fishermen may sell commercial species legally taken by themselves to a resident licensed wholesale aquatic life dealer without additional licenses. Retail, wholesale, non-resident, stocking, vehicle or location-based sales can require dealer licenses.
Can I use commercial gear as a holding crib?
No. A crib is a pen, cage or similar device used to hold fish after sorting. It is unlawful to use a commercial fishing device as a crib.
Who should I call for Illinois commercial fishing questions?
For license help call 217-782-2965. For business-name setup call 217-785-3423 or 217-782-2965. For the Commercial Fishing Program call 618-444-3078. For Lake Michigan commercial fishery questions call 847-294-4134.
Final Practical Advice
Do not treat Illinois commercial fishing as a single license purchase. The real compliance stack is: commercial license, sport license, current device tags, correct tag placement, watercraft device tag if needed, open water, legal method, mesh/gear compliance, check interval, recordkeeping, buyer/dealer rules and monthly reports.
Best path: define your activity → confirm resident/business status → call IDNR if business-name setup is needed → buy commercial and sport licenses → buy correct tags → tag gear correctly → confirm water and gear limits → keep records from day one → submit required reports on time.
