Keeping alligator gar in Texas is legal for private, non-commercial owners, and a standard fishing license is the only permit you need if you catch one yourself from public water. The rules that actually shape what you can do sit around that fact: a one-fish daily bag limit, a 24-hour reporting requirement, tighter restrictions on the Trinity River, and a statute that can hold you responsible if a fish you keep escapes into public water. The Texas Parks and Wildlife Department (TPWD) treats alligator gar as a native nongame species, which keeps the paperwork light but the compliance real.
Catching One Legally
To take an alligator gar from public water, you need a valid Texas fishing license. The Resident Freshwater Package runs $30.1Texas Parks & Wildlife Department. Fishing Licenses and Packages The statewide daily bag limit is one alligator gar of any size, with no minimum length.2Texas Parks & Wildlife Department. Alligator Gar Special Restrictions and Reporting
Trinity River System
The Trinity River and its tributaries carry stricter limits. From the I-30 bridge in Dallas downstream to the I-10 bridge in Chambers County, including Lake Livingston and the East Fork up to the dam at Lake Ray Hubbard, the fish you keep must be under 48 inches. Anything larger requires a harvest authorization from a TPWD drawing held each September. If selected, you get a non-transferable authorization to take one alligator gar over 48 inches from the Trinity system that year.2Texas Parks & Wildlife Department.

The 24-Hour Report
Every alligator gar harvested from public water in Texas, except from Falcon International Reservoir, has to be reported to TPWD within 24 hours through the TPWD mobile app or online system.2Texas Parks & Wildlife Department. Alligator Gar Special Restrictions and Reporting The rule applies whether you eat the fish, mount it, or keep it alive in a tank. Missing the window is a citable offense.
Permits You Don’t Need
For a private individual housing an alligator gar at home, TPWD does not require any captive-keeping permit beyond the fishing license used to catch it.
The Permit to Possess or Sell Nongame Fish Taken from Public Fresh Waters is a commercial permit. It’s required for catching nongame fish for sale, or for collecting shad in quantities of 30 gallons or more.3Texas Parks and Wildlife Department. License Requirements for Permit to Possess or Sell Nongame Fish Taken from Public Fresh Waters Keeping one gar in a home tank does not trigger it.
Exotic Species Permits also don’t apply. Those cover nonindigenous species not normally found in Texas public waters.4State of Texas. Texas Code Parks and Wildlife 66.007 – Exotic Harmful or Potentially Harmful Fish and Shellfish Alligator gar are native to Texas.
Buying Instead of Catching
Alligator gar can be purchased from licensed aquaculture facilities and fish dealers operating under TPWD regulations. Buying skips the harvest reporting requirement, because the fish was never taken from public water by you. Confirm the seller holds the proper commercial licenses and can document how the fish was legally bred or acquired.
If You’re Bowfishing
Bowfishing changes one thing significantly: once any gar is taken with archery equipment, it cannot be released back into the water. The rule covers all gar species.5Texas Parks & Wildlife Department. Bow Fishing Regulations If your plan is to bring an alligator gar home alive, bowfishing removes your option to change your mind at the boat.
On the Trinity River system, nighttime bowfishing for alligator gar is restricted. Between 30 minutes after sunset and 30 minutes before sunrise, taking or possessing one with archery equipment or a crossbow requires a harvest authorization from the TPWD drawing.
Containment and the Escape Problem
Texas law generally prohibits placing any fish into public water without a TPWD permit, but the statute exempts native nongame fish in most waters. Alligator gar fit that category, so the exception can apply. It disappears in waters the commission has designated as habitat for threatened or endangered species, where a permit is required to release anything.6State of Texas. Texas Code Parks and Wildlife 66.015 – Introduction of Fish, Shellfish, and Aquatic Plants
The trap sits a little further down the same statute. If you keep fish in nonpublic water, such as a backyard pond, and they escape into public water, you can violate the law without a permit.6State of Texas. Texas Code Parks and Wildlife 66.015 – Introduction of Fish, Shellfish, and Aquatic Plants A flooded pond that lets your gar into a creek is a legal problem, not just a lost fish. Containment matters as a compliance issue.
What Violations Cost
Fishing violations in Texas run from Class C misdemeanors ($25 to $500) up through state jail felonies ($1,500 to $10,000 and up to two years in jail), depending on severity. TPWD can also suspend or revoke fishing and hunting licenses for up to five years, and the department pursues civil restitution for wildlife resource losses separately from criminal penalties. Unpaid restitution blocks any future license, tag, or permit issuance.7Texas Parks & Wildlife Department. Laws, Penalties and Restitution
Whether You Can Actually House One
No Texas rule sets a minimum tank size for a privately held alligator gar. The fish sets its own. Alligator gar are the largest freshwater fish in North America, reaching eight feet and more than 300 pounds.8FWC. Alligator Gar Juveniles grow quickly. Growth slows after sexual maturity around age 10, but they keep getting bigger. A fish that fits in a 75-gallon tank now will outgrow it within a year or two.
Experienced keepers commonly recommend at least several thousand gallons for a single adult, with some suggesting no less than 5,000 gallons for long-term housing. Running filtration, heating, and water-quality equipment at that scale can cost $50 to $100 or more per month in electricity, before the tank itself, food, and replacement equipment. The legal barriers to keeping alligator gar in Texas are low. The practical ones are not, and the escape-liability rule means the enclosure needs to be planned before the fish arrives.
