Catfish Fishing Regulations in New Hampshire: What Every Angler Needs to Know
July 16, 2026
New Hampshire may be best known for its trout streams and landlocked salmon lakes, but catfish have a quiet and loyal following across the Granite State. Whether you’re chasing the native brown bullhead in a warm-water pond or hunting the growing channel catfish population along the Connecticut River, understanding the rules before you launch keeps you legal and helps protect the fishery for future seasons.
The 2026 New Hampshire Freshwater Fishing Digest provides official statewide fishing regulations, species information, and reporting guidance for anglers fishing New Hampshire waters. This guide breaks down everything catfish-specific — species, seasons, limits, legal methods, license costs, and the top spots to wet a line.
Pro Tip: Always carry a printed or digital copy of the current NH Freshwater Fishing Digest when you head out. Regulations can vary by waterbody, and having the rules on hand keeps you ready if a conservation officer stops by.
Catfish Species Found in New Hampshire
New Hampshire is home to two catfish species that anglers realistically target: the brown bullhead and the channel catfish. The brown bullhead (Ameiurus nebulosus) is by far the more widespread of the two. Brown bullhead are found in nearly all lakes, ponds, and medium to large rivers across the state. Locals have long called this fish “hornpout,” and it remains a staple of warm summer nights with a worm on the bottom.
The channel catfish (Ictalurus punctatus) tells a different story. Channel catfish are found through most of North America east of the Rockies, but they are not native to New Hampshire, and the only known fishable population is in the Connecticut River. The New Hampshire portion of the Connecticut River has been slowly populated with channel cats over the past decade as fish from Massachusetts have moved upstream, and they are currently found from the Bellows Falls Dam in Walpole to the Massachusetts border.
Channel catfish are a typical, if not slender, version of most catfish, possessing a deeply forked tail and a slightly protruding upper jaw. Most are dark gray along the back, with a light yellow or greenish yellow hue along the sides and a white belly. Brown bullhead, by contrast, have a rounded or slightly notched tail and a mottled brown-to-black coloration — a key distinction when you’re deciding whether to keep or release a fish.
There are no specific conservation or management objectives for channel catfish in New Hampshire, though an increasing interest in angling for catfish in the state will warrant greater study. The NH Fish and Game Department continues to collect baseline data on channel catfish distribution throughout the state.
Catfish Season Dates in New Hampshire
New Hampshire does not impose a closed season specifically for catfish or bullhead. Both brown bullhead and channel catfish fall under the state’s general warmwater species framework, which means they can be targeted year-round in most waters — including through the ice in winter.
Seasons can vary by river or lake, and by species. Some waters may have year-round access for certain species with catch limits, while others open seasonally. If you plan to fish a waterbody that also holds trout or landlocked salmon, pay close attention to any special rules for that water. Some waterbodies have special rules that may differ from, or be in addition to, the general fishing rules for lakes and ponds.
Trout Ponds are managed for trout and are open to fishing for all species from the fourth Saturday in April through October 15. Fishing for any species is prohibited from October 16 until the fourth Saturday in April the following year. If you’re targeting bullhead in a designated Trout Pond, that seasonal closure applies to you as well — even though catfish are not the managed species.
Important Note: Always check the specific waterbody designation in the NH Freshwater Fishing Digest before heading out. A pond that looks like a standard warmwater fishery may carry Trout Pond or other special-rule status that restricts fishing outside a defined season.
New Hampshire also designates free fishing days — no license is needed on January 17 and June 6 in 2026 to fish anywhere in the state. These are great opportunities to introduce a friend or family member to catfishing without the upfront license cost.
Daily Bag Limits for Catfish in New Hampshire
New Hampshire groups catfish and bullhead under the “other species” or warmwater species category in its regulation tables, and no species-specific daily bag limit is published for catfish or hornpout in the general statewide rules. This means the general possession rules apply.
Exceeding daily bag limits of fish is prohibited, whether taken from one or several waterbodies. No person may have in their possession at one time more wildlife — including fish — than they may lawfully take in two days. Because no catfish-specific bag limit is listed in the general rules, you should confirm the current limit directly in the 2026 NH Freshwater Fishing Digest or by contacting the NH Fish and Game Department before your trip.
To continue to take or attempt to take fish after filling the daily bag limit for that species of fish is prohibited. Even if you’re unsure of the precise number, stopping when you’ve reached what a reasonable limit would be — and verifying in advance — is the safest approach. Always verify current regulations before fishing, as regulations change frequently. Visit the official New Hampshire Fish and Game Department website for the most up-to-date rules, emergency closures, and special regulations.
| Species | Season | Daily Bag Limit | Notes |
|---|---|---|---|
| Brown Bullhead (Hornpout) | Year-round (general waters) | Check current digest | Trout Pond closures apply if applicable |
| Channel Catfish | Year-round (Connecticut River) | Check current digest | Found from Bellows Falls Dam to MA border |
Size and Length Limits for Catfish in New Hampshire
New Hampshire does not publish a statewide minimum size or length limit specifically for catfish or brown bullhead in its general freshwater rules. Unlike trout or landlocked salmon — which carry defined minimum lengths — catfish fall outside the species-specific size limit framework in most New Hampshire waters.
Bag limits and size limits help ensure recruitment and balance among populations. While no mandatory minimum size applies to bullhead or channel catfish under the current general rules, practicing voluntary size selection — especially releasing smaller fish to grow — supports the long-term health of the fishery. This is particularly relevant for channel catfish in the Connecticut River, where the population is still establishing itself.
General fishing rules apply to most lakes and ponds in the state. Follow the seasons, bag limits, length limits, and important notes listed with each species in the regulation chart. Confirm that no waterbody-specific size restrictions apply to the water you intend to fish, as individual lakes and rivers can carry additional rules beyond the statewide baseline.
Pro Tip: For channel catfish on the Connecticut River, releasing fish under 12 inches voluntarily helps sustain this still-developing population. The NH Fish and Game Department is actively monitoring channel catfish distribution, so every fish that grows to maturity contributes to a stronger future fishery.
Legal Methods for Catching Catfish in New Hampshire
New Hampshire allows a range of standard angling methods for catfish, but the state also enforces several gear restrictions that every angler must know. Rod and line fishing with bait is the most common and straightforward approach, and it’s fully legal in all open waters.
No fish may be taken by use of a set line (as defined in the regulations) in freshwater, which would include so-called “jug fishing.” This is a critical rule for catfish anglers used to fishing states like Tennessee or Missouri, where jug fishing is a popular tradition. In New Hampshire, every line must be attended.
- Rod and reel fishing: Fully legal; the most common method for both bullhead and channel catfish
- Bait: Nightcrawlers, cut bait, chicken liver, and stink baits are all effective and legal
- Jug fishing / set lines: Prohibited in all freshwaters
- Snagging: Prohibited — any fish accidentally snagged must be immediately released
- Lead sinkers and jigs: Prohibited if weighing 1 ounce or less, regardless of length
Snagging fish in freshwaters is prohibited. Any fish accidentally snagged must be immediately released to the water. State law also prohibits the use of lead sinkers and jigs weighing 1 ounce or less, regardless of length, in all fresh waters of New Hampshire. Use tin, tungsten, or other non-lead alternatives to stay compliant.
While taking fish in open water, two hooks may be used for bait per line — one with a single hook point and the other with no more than three hook points. This applies to general open waters; check specific waterbody rules if you’re fishing a designated lake trout or salmon lake, where single-hook restrictions may apply.
You can also compare legal catfishing methods in neighboring states. Anglers fishing the tri-state area may find it useful to review catfish regulations in Vermont or check the rules for catfish fishing in New York if you fish border waters.
Fishing License Requirements for Catfish in New Hampshire
A valid New Hampshire freshwater fishing license is required to target catfish in inland waters. Most anglers 16 and older need a valid license to fish in New Hampshire, including freshwater. The main exceptions apply to junior anglers below 16 and disabled veterans.
License costs, as of 2026, include $45 for residents and $63 for nonresidents for a freshwater annual license, with transaction and agent fees that may apply. The NH Fish and Game Department also offers short-term and other license types for anglers who don’t need a full-year option. License types include annual, short-term, and senior options, and endorsements may apply depending on the fishery.
| License Type | Resident Fee (2026) | Nonresident Fee (2026) |
|---|---|---|
| Annual Freshwater | $45 | $63 |
| Short-Term / Other | Varies | Varies |
| Under Age 16 | Free | Free |
It is advisable to carry proof of license and be prepared to present it to wardens on request. You can purchase a license online through the NH Fish and Game Department website, at licensed agents statewide, or at many sporting goods retailers. Keep a digital copy of your license and regulations on your phone for field checks.
NH Fish and Game wardens enforce fishing laws to protect fish populations and public safety. Penalties for violations can range from warnings and fines to license suspension or criminal charges for serious offenses. Common violations include fishing out of season, exceeding bag limits, using illegal gear, or fishing without a required license.
If you fish other states in the region, the licensing frameworks differ. See how requirements compare with catfish regulations in Pennsylvania or catfish fishing rules in New Jersey.
Best Catfish Fishing Spots in New Hampshire
New Hampshire’s catfish fishing is concentrated in warm, slow-moving or still waters — the kind of habitat where bullhead and channel cats thrive. The state’s official Fish and Game Department publishes a “Where to Fish” resource that lists recommended locations by species, and it’s one of the most practical planning tools available to anglers.
Connecticut River
Channel catfish are found in the New Hampshire section of the Connecticut River from the Bellows Falls Dam in Walpole to the Massachusetts border. The river holds native brook trout, rainbow trout, large brown trout, shad, smallmouth bass, striped bass, carp, catfish, American eel, and several other species of game fish. For channel cats specifically, focus on deeper pools, undercut banks, and areas below dams where current slows and baitfish concentrate. Summer evenings and overnight sessions with cut bait or chicken liver produce the best results.
Merrimack River
Located in south-central New Hampshire, the Merrimack River is home to many native fish species. You can find fish that migrate from the sea to spawn, and those who enjoy sport fishing can catch bass, perch, pickerel, salmon, sunfish, and catfish. Prime fishing spots along the Merrimack include Arms Park, Amoskeag Bridge, Moore’s Falls Conservation Area, Taylor Falls Bridge, Greely Park, and near any of the bridges along Route 111. Brown bullhead are the primary catfish target here, and a simple bottom rig with a nightcrawler works well from shore.
Statewide Lakes and Ponds
Hornpout are found in the Connecticut River, Howe Reservoir in Dublin, Grassy Pond in Rindge, Child’s Bog in Harrisville, Meetinghouse Pond in Marlborough, Island Pond in Stoddard, McDowell Lake in Peterborough, Mud Pond in Dublin, Baboosic Lake in Amherst, and most other lakes, ponds, and rivers. This list illustrates just how widespread brown bullhead are — if there’s a warm, weedy pond near you in New Hampshire, there’s a good chance hornpout are in it.
Contoocook Lake in Cheshire County is a good place for freshwater fishing with catfish, sunfish, and bass, formed by a dam on the Contoocook River and featuring a warm-water fishery. The lake also contains an excellent fishery for white perch, bluegills, and hornpout. It’s a solid choice for anglers in the southwestern part of the state.
Additional hornpout locations include Hoit Marsh in Concord, Turtletown Pond in Concord, Turkey Pond in Concord, Harvey Lake in Northwood, Pawtuckaway Lake in Nottingham, Beaver Lake in Derry, Powwow Pond in Kingston, and Swains Lake in Barrington, among others.
Pro Tip: Brown bullhead feed most actively after dark. Plan evening or overnight sessions during the warmer months — June through August — when water temperatures peak and hornpout move into shallower water to feed. A simple slip sinker rig with a nightcrawler or piece of cut sucker is hard to beat.
For a broader look at how catfish regulations compare across the country, see how New Hampshire stacks up against catfish rules in North Carolina, Tennessee catfish regulations, or the rules for catfishing in Missouri — states where catfish culture runs much deeper and regulations reflect it.
New Hampshire may not be the first state that comes to mind for catfish, but the combination of ubiquitous brown bullhead and a growing channel catfish population in the Connecticut River gives anglers real options. Know your species, follow the gear rules, carry a valid license, and confirm the current regulations in the 2026 NH Freshwater Fishing Digest before every trip. The fishing is there — you just need to show up prepared.
