Texas Coastal & Inland Waters

A saltwater endorsement is required to fish Texas coastal waters, while a freshwater endorsement covers inland waters, and some waters require both. Texas Parks and Wildlife defines where each endorsement applies, including specific boundary rules for reservoirs and tidal areas. Check the general fishing regulations for details on how waters are classified and which licence applies where.

Texas Federal Waters & Offshore Rules

Beyond state waters, federal rules managed by NOAA Fisheries and the regional fishery management councils apply, typically from 3 to 200 nautical miles offshore. Anglers targeting species such as tuna, billfish, swordfish, or sharks in federal waters must hold a federal Atlantic HMS vessel permit issued through NOAA Fisheries. You still need a valid Texas fishing license and saltwater endorsement to possess or land any fish taken in federal waters at a Texas port.

Texas Saltwater Fishing License

Anglers need a Texas fishing license with a saltwater endorsement to fish coastal waters, and Texas Parks and Wildlife issues it. Anglers under 17 and the oldest residents are exempt, as is everyone on the annual Free Fishing Day. Fishing from banks or piers inside Texas State Parks also needs no license.
