Check the 35-Inch Rule, River Boundary and Night Method Before Targeting Flatheads
Ohio flathead catfish fishing is not governed by one simple “no-limit” rule. Fish shorter than 35 inches fall under one statewide category, trophy-size fish have a separate statewide harvest restriction, and the legal method can change the equipment, marking and attendance requirements.
This practical guide explains license costs, the 35-inch threshold, Ohio River jurisdiction, rod limits, trotlines, banklines, jug fishing, restricted night-fishing areas, bait transport and a complete after-dark safety plan.
Do You Need an Ohio License to Fish for Flathead Catfish?
Most Ohio residents and nonresidents age 16 or older need a valid Ohio fishing license to target flathead catfish in public rivers, streams, reservoirs and lakes. Persons younger than 16 generally do not need a license, but all harvest, method, access and safety rules still apply.
Ohio does not require a separate flathead catfish stamp. Most anglers need the correct resident or nonresident base fishing license.
The statewide rule has no general minimum length and no numeric daily limit for flathead catfish shorter than 35 inches. However, an angler may take only one flathead catfish measuring 35 inches or longer statewide per day.
Ohio Flathead Catfish Rules in One View
No statewide numeric daily limit is listed when no site-specific or boundary-water rule replaces it.
Only one flathead catfish measuring 35 inches or longer may be taken statewide per day.
An Ohio angler may use a maximum of three fishing rods statewide.
What Kind of Ohio Flathead Trip Are You Planning?
Rod-and-reel river trip
Use a standard fishing license, stay within the three-rod maximum and check the exact river for site-specific or boundary-water rules.
- Confirm public bank access
- Carry a rigid measuring board
- Check dam and navigation hazards
- Save the license offline
Ohio River night trip
Identify the Western or Eastern Unit, the shoreline or boat position, the applicable state license and which state’s catfish rules control.
- Identify the state boundary
- Review navigation lights
- Monitor commercial traffic
- Confirm reciprocal-license limits
Trotline, bankline or jug trip
Do not apply rod-and-reel rules to unattended or alternate equipment. Each method has its own hook, marking, checking and location requirements.
- Mark every required device
- Use lawful single hooks
- Check equipment on time
- Remove lines after use

Fish Ohio size
A legally caught flathead catfish measuring 35 inches qualifies for Ohio’s Fish Ohio recognition program.
Release option
An angler may photograph, measure and release a large flathead when safe handling conditions allow.
How to Measure an Ohio Flathead Catfish
-
Use a rigid measuring board or dependable tape.
Prepare it before fishing so the fish is not left unsupported while equipment is located. -
Close the fish’s mouth.
Start the measurement at the forward end of the closed mouth. -
Lay the fish flat and straight.
Do not measure around the curve of the body. -
Compress the tail fin.
Measure total length to the farthest tail point with the fin compressed. -
Read the result before retaining the fish.
When the fish measures 35 inches or longer, the statewide trophy-size limit applies. -
Record the catch.
Save the date, waterbody, length and whether the fish was retained or released.
Ohio River Flathead Catfish License and Regulation Rules
The Ohio River is divided into an Ohio–Kentucky Western Unit and an Ohio–West Virginia Eastern Unit. Catfish are not included among the small list of fully unified species rules shown in the Ohio summary, so anglers must identify which state’s remaining catfish rules control.
Ohio–Kentucky border
Boat anglers in the Western Unit follow the fishing regulations of the state by which they are licensed. Anglers fishing from the Ohio bank follow Ohio regulations.
Kentucky regulations apply to boat anglers fishing beyond the historic low-water boundary identified in the official Ohio River materials.
Action: confirm the license state and boat position before retaining a flathead.
Ohio–West Virginia border
Ohio and West Virginia honor each other’s resident licenses along specified common-border waters. The agreement applies to Ohio and West Virginia residents, not automatically to every nonresident.
West Virginia regulations apply to main-stem boat anglers and anglers on the West Virginia side as described in the current Ohio booklet.
Action: identify the state side, residency and exact reciprocal-water boundary.
Ohio River flathead decision sequence
Identify the unit
Western Ohio–Kentucky or Eastern Ohio–West Virginia.
Identify the license
Ohio, Kentucky or West Virginia privilege.
Identify the position
Ohio shore, opposite shore, main-stem boat or tributary.
Apply catfish rules
Use the state rule controlling that exact situation.
Three-line rule on the Ohio River
Ohio’s maximum of three fishing rods or lines applies statewide, including counties within the Ohio River fishing units.
Is Night Fishing for Flathead Catfish Legal in Ohio?
Night fishing is generally possible on Ohio public waters when the water, park and access area remain open and no special regulation limits fishing to daylight hours.
A fishing license does not override park closing times, locked gates, restricted dam areas, private-property boundaries, seasonal closures or posted safety rules.
Fishing hours
Check the exact river section, park, boat ramp and access point for posted hours or seasonal restrictions.
Access hours
A river may remain legally fishable while the chosen parking lot, park or launch closes at night.
Private property
Public water does not automatically create permission to cross or occupy private riverbank property.
Dam restrictions
Observe posted exclusion zones, navigation structures and method-specific distance restrictions.
Boat lighting
A boat operated after dark must display the required navigation lights and carry required equipment.
Personal watercraft
Ohio does not permit personal watercraft operation between sunset and sunrise.
Ohio River Sections Where Night Fishing Is Temporarily Prohibited
From March 1 through April 30, 2026, fishing is permitted only from sunrise to sunset in specified portions of four rivers. The restriction applies to fishing activity in those sections, not only to walleye anglers.
| River | Restricted section | Effective period | Night-trip action |
|---|---|---|---|
| Maumee River | Ohio Turnpike bridge to the easternmost point of Missionary Island, and State Route 295 bridge to Grand Rapids Providence Dam | March 1–April 30, 2026 | Do not fish these sections between sunset and sunrise |
| Sandusky River | Waterworks Dam in Tiffin to the northern tip of Brady’s Island in Fremont | March 1–April 30, 2026 | Move outside the restricted section or fish during daylight |
| Portage River | State Route 19 to the dam at Elmore | March 1–April 30, 2026 | Verify the bridge and dam endpoints before fishing |
| Mahoning River | Dam at Berlin Reservoir to Lake Milton | March 1–April 30, 2026 | Night fishing is not permitted in the listed section during this period |
Ohio Flathead Catfish Rod, Hook and Landing Rules
Three fishing rods per angler
Ohio permits a maximum of three fishing rods statewide. The limit also applies in counties that make up the Ohio River fishing units.
Practical action: count every active rod assigned to the angler, including rods placed in holders.
No hand fishing for catfish
Ohio excludes catfish from fish species that may be taken by hand. Flathead noodling or hand-grabbing is therefore not a lawful method.
Practical action: use a legal angling or approved alternate-line method.
Do not snag flatheads
Snagging means hooking a fish somewhere other than inside the mouth. Flathead catfish must be caught by a lawful method.
Practical action: release an unlawfully snagged fish immediately.
Keep the fish whole on the water
Ohio generally prohibits possessing fish in a form other than whole while on or unloading from a boat, wading or fishing where a license is required.
Practical action: do not fillet a retained flathead at the bank or on the boat.

Ohio Flathead Catfish Live Bait and Transport Rules
Many flathead anglers use fish or other natural bait, but bait collection, possession and release are regulated separately from the flathead harvest limit.
Do not move bait between waters
Ohio prohibits releasing a fish or aquatic invertebrate into public water from which it did not originate.
Action: never dump unused live bait or bait-container water into another river or lake.
Cast nets are for forage fish
Forage fish and minnows may be taken with legal cast nets. Other fish caught in the net must be released immediately unharmed.
Action: verify the current mesh, diameter and dam-area restrictions before collecting bait.
Bait possession quantities
Without a bait-dealer permit, Ohio limits possession of crayfish and combined minnows, crayfish and other baitfish.
Action: review the current bait section when carrying large quantities for several anglers.
Clean equipment
Remove vegetation, mud and aquatic organisms from nets, boats and bait containers before moving to another water.
Action: drain lawful equipment where required and follow current invasive-species guidance.

Common Ohio Flathead Catfish Fishing Mistakes
Calling 35 inches the minimum size
Ohio has no general minimum flathead length. The 35-inch mark triggers the large-fish harvest limit.
Keeping two trophy flatheads from different rivers
The one-fish limit for flatheads measuring 35 inches or longer is statewide.
Using four or more rods
Ohio permits a maximum of three fishing rods per angler statewide.
Trying to hand-grab a flathead
Catfish may not be taken by hand in Ohio.
Leaving jug lines unattended
Floatlines must be freely adrift and attended by the user at all times.
Attaching a bankline to a dock
Banklines must be attached to shore above water and not to a dock, pier, boat, wall or other prohibited structure.
Setting a trotline below a dam
Trotlines may not be used within 1,000 feet downstream of a dam.
Fishing a daylight-only section at night
Specified Maumee, Sandusky, Portage and Mahoning sections are sunrise-to-sunset only during March and April.
Using the launch state as the Ohio River rule
The controlling regulation can depend on the unit, license state, shoreline and boat position.
Dumping live bait into another river
Do not release baitfish or aquatic invertebrates into public water from which they did not originate.
Filleting a fish at the river
Retained fish generally must remain whole while on the water, wading or unloading a boat.
Assuming public water means public bank
A fishing license does not create permission to cross or occupy private land.
