Measure the Trap, Mark the Owner and Check Every Fish Before Keeping It
Ohio changed the legal entrance size for minnow and bait-fish traps in 2026. The opening may now be as large as two inches, but the trap still must remain within the statewide overall length and width limits.
This guide shows recreational anglers how to measure a trap correctly, prepare a legal identification tag, choose an appropriate location, sort the catch and avoid unlawful transport, release or sale of collected bait.
2 inches max
What Are the Ohio Bait Fish Trap Rules for 2026?
A recreational minnow or bait-fish trap may not measure more than 24 inches in its greatest overall length or more than 12 inches in its greatest overall width.
The trap entrance may not exceed 2 inches in diameter or 2 inches in height. The two-inch opening is a highlighted 2026 regulation change.
Every trap must have identification attached showing either the owner or user’s name and address or the person’s unique Ohio Division of Wildlife customer identification number. The information must remain legible.
The trap may be used only for bait fish and crayfish authorized under Ohio’s bait-collection rules. A bait trap is not a general-purpose trap for game fish or any fish that happens to enter it.
Ohio Increased the Maximum Bait-Trap Opening to Two Inches
The official 2026–27 Ohio Fishing Regulations identify the bait-fish trap entrance change as one of the season’s main regulation updates.
A legal opening may now be up to 2 inches in diameter when it is round, or up to 2 inches in height when the entrance is measured by height.
The change affects the entrance only. It does not increase the overall trap limits of 24 inches in length and 12 inches in width. It also does not remove the identification-tag requirement or expand the list of species that may legally be retained.
Ohio Minnow and Bait Fish Trap Size Requirements
Ohio measures the complete trap, not only the central mesh cylinder. Funnels, doors, frames and permanently attached parts can affect the overall measurement.
2 inches
maximum
| Trap feature | Ohio maximum | Where to measure | Common error |
|---|---|---|---|
| Greatest overall length | 24 inches | From the farthest outside point at one end to the farthest outside point at the other end | Measuring only the mesh body and ignoring the funnel or frame |
| Greatest overall width | 12 inches | Across the widest outside portion of the complete trap | Using the advertised diameter instead of checking the actual trap |
| Round entrance | 2 inches in diameter | Straight across the widest inside portion of the opening | Measuring radius instead of full diameter |
| Non-round entrance | 2 inches in height | Measure the entrance height at its greatest open point | Checking only one side of a flexible or damaged funnel |
| Multiple entrances | Every opening must comply | Measure each entrance independently | Measuring only the smaller entrance |
How to Measure an Ohio Bait Fish Trap Correctly
-
Place the empty trap on a flat surface.
Close all doors, clips and funnels exactly as they will be used in the water. -
Find the two farthest outside points.
Measure the complete overall length, including end funnels, rings, frames and rigid projections. -
Rotate the trap and find its widest point.
Measure the greatest overall width rather than relying on packaging or a seller’s description. -
Measure every entrance separately.
For a round opening, measure the full inside diameter. For another shape, measure the greatest opening height. -
Check the trap after repairs.
A bent funnel, stretched mesh, replacement ring or homemade door can change an otherwise legal measurement. -
Photograph the measurements.
Keep clear photos showing the tape measure against the trap before your trip.
What Information Must Be Attached to an Ohio Bait Fish Trap?
The trap must carry one of two identification options:
Owner or user’s name and address
- Full name that reasonably identifies the person
- Complete mailing or residential address
- Writing that remains legible while the trap is in use
Division of Wildlife customer ID
- Use the owner or user’s unique customer identification number
- Write or engrave the complete number accurately
- Keep it readable and securely attached
Make the tag durable and easy to inspect
- Use waterproof plastic, engraved metal or another weather-resistant material
- Attach it with corrosion-resistant wire, cable tie or a secure clip
- Place it where it can be read without dismantling the trap
- Replace faded marker, torn tape or missing digits before use
- Check the tag every time the trap is set
Do You Need an Ohio Fishing License to Use a Bait Fish Trap?
People age 16 or older generally need a valid Ohio fishing license when taking fish from public Ohio waters unless a specific license exemption applies.
The bait-fish trap rule does not create a separate exemption from the ordinary fishing-license requirement. The angler must satisfy both the license rule and the trap-equipment rules.
Public water
An adult collecting bait from public water should confirm that the appropriate Ohio fishing license is active.
Person under 16
A person under 16 generally does not need an Ohio fishing license, but trap-size, tag, species and possession rules still apply.
Private property
Always obtain the owner’s permission and separately check whether a private-property license exemption applies.
Official Ohio fishing license information
Why use this link: ODNR lists current license products, exemptions and official purchase access.
After opening: confirm whether the collector needs a license, then verify that the license is active before setting the trap.
What Can Legally Be Taken in an Ohio Bait Fish Trap?
Ohio permits minnow or bait-fish traps to take the bait fish and crayfish authorized under Ohio Administrative Code Rule 1501:31-13-04.
The detailed bait rule is the correct source for species qualifications. Do not keep a fish merely because it is small or because it entered the trap accidentally.
Authorized bait fish and crayfish
- Properly identified minnows covered by the current bait rule
- Crayfish subject to possession and transport restrictions
- Other bait categories only when specifically authorized
Game fish and unidentified catch
- Bass, crappie, walleye or other game fish entering accidentally
- Protected, prohibited or unfamiliar species
- Fish exceeding an applicable bait-size qualification
- Aquatic animals not covered by the trap rule
Where Can You Set a Bait Fish Trap in Ohio?
Ohio generally authorizes bait-fish traps for the specified bait species, but that does not mean every shoreline, park pond, hatchery, refuge or privately owned access point is open to trap use.
Check the exact water
Search the lake, river, stream, reservoir, wildlife area or park rules—not only the statewide regulation.
Obtain property permission
A fishing license or legal trap does not grant permission to cross private land, use a private dock or enter a restricted shoreline.
Read posted signs
“No fishing,” controlled-access, refuge, beach, dam or method-specific signs can restrict activity at the location.
Avoid hatchery waters
State fish hatcheries and posted wildlife ponds may have collection restrictions or complete fishing closures.
Do not obstruct navigation
Place the trap where it will not create a hazard for boats, paddlers, swimmers, fishing lines or public access.
Confirm boundary water rules
Lake Erie, the Ohio River and shared waters can involve additional district or boundary regulations.
How to Set and Use an Ohio Bait Fish Trap Responsibly
Confirm length, width and every opening.
Attach the correct owner identification.
Choose a lawful, safe and permitted location.
Inspect the trap frequently and handle catch carefully.
Keep only lawful bait and release other catch.
-
Confirm the license and location.
Check the collector’s fishing-license status, public-access rules, property permission and any posted restrictions. -
Inspect the complete trap.
Measure the overall trap and entrances. Repair broken mesh, sharp wire or a door that may remain open. -
Attach the identification tag.
Use the owner/user’s name and address or customer ID. Pull firmly on the attachment to confirm it will not detach. -
Use a secure retrieval line.
Choose a line strong enough to recover the trap without entering dangerous current or deep water. -
Position the trap safely.
Do not block a boat lane, swimming area, launch, culvert, dam structure or another angler’s access. -
Check it regularly.
Frequent inspection reduces stress on accidental catch and lowers the chance of theft, tag loss, storm damage or animal mortality. -
Sort catch at the source water.
Identify every fish or crayfish before placing it into a transport container. -
Remove the trap when finished.
Do not abandon equipment, line, bait containers or damaged mesh at the water.
What to Do When You Retrieve the Trap
Keep it in water
Prepare the bait bucket before opening the trap and minimize the time aquatic animals remain exposed to air.
Identify species
Separate minnows, crayfish, game fish and any unknown or protected-looking catch.
Measure when needed
Check any species that has a bait-size qualification before keeping it.
Release other catch
Return unauthorized, unwanted or unidentified catch promptly and unharmed to the same water.
Ohio Recreational Bait and Crayfish Possession Limits
People who are not licensed bait dealers are subject to statewide bait possession limits. These limits apply even when every animal was caught in a legal trap.
| Bait category | Unlicensed possession rule | What it means in practice |
|---|---|---|
| Crayfish | No more than 100 | Count every crayfish retained across traps and containers |
| Crayfish, minnows and other baitfish combined | No more than 500 in combination | The total combined bait count cannot exceed the statewide unlicensed limit |
| Licensed bait dealer | Different commercial authority may apply | Dealer and collector permits carry separate records, transport and business requirements |
Bait Transport, Release and Water-to-Water Movement
Ohio prohibits releasing fish or aquatic invertebrates into state waters from which they did not originate. This includes crayfish and other collected aquatic animals.
Use the bait where it was collected
- Keep a clear note of the source water
- Separate bait collected from different locations
- Return unwanted live catch only to its original water
- Dispose of unused bait lawfully rather than dumping it elsewhere
Move live organisms between waters
- Release leftover minnows into another lake
- Dump crayfish into a home pond from public water
- Mix bait collected from several waters and release the remainder
- Introduce an unfamiliar or exotic species
Can You Sell Bait Caught in an Ohio Bait Fish Trap?
A recreational fishing license does not authorize a person to operate as a bait dealer. Ohio requires a bait dealer’s permit for people buying or selling minnows, crayfish and hellgrammites.
Collecting lawful bait for your own fishing
This is generally recreational activity when the fishing license, equipment, species, possession and location rules are followed.
Selling, trading or operating a bait business
Commercial activity can require a bait dealer or bait collector permit and additional compliance beyond this recreational guide.

Ohio Bait Fish Trap Mistakes to Avoid
Measuring the body only
The maximum length and width apply to the greatest overall dimensions of the trap.
Using an oversized replacement funnel
A repair can create an entrance larger than the current two-inch limit.
Writing only a telephone number
The identification must use the listed name-and-address option or customer ID option.
Keeping every small fish
Small size does not automatically make a fish legal bait or legal trap catch.
Ignoring a posted restriction
Fishing may be allowed at a property while traps or bait collection are restricted.
Moving bait between lakes
Unused bait must not be released into water from which it did not originate.
Exceeding bait possession limits
A legal trap does not authorize unlimited possession of crayfish, minnows or other baitfish.
Selling recreationally collected bait
Buying or selling covered bait can require an Ohio bait dealer or collector permit.
Leaving a damaged trap behind
Abandoned gear can continue capturing wildlife and create a navigation or litter hazard.
