🪪 Do I need a fishing license to fish at Mud River?

Fishing in Florida requires a valid state fishing license for anglers. Freshwater, saltwater, or combination licenses are available for residents and visitors, purchasable online, by phone, or at authorized retailers.

In Florida, no fishing license is required for anglers under 16 or residents 65 and older. A few other exceptions worth knowing:

  • Free fishing days — most states designate 1–2 weekends a year where anyone can fish without a license

  • Tribal waters — tribal members fishing on tribal land operate under separate tribal regulations

  • Private ponds — landowners fishing their own water typically don't need a license

Non-residents usually pay more for a license than residents. Some species also require an extra stamp or endorsement on top of your base license.
