Ha! That's called land-locked!

We can fish freshwater with no license as long as we don't use reels (line retrieval devices) ... basically cane poles.

As for salt water:

Florida residents who only saltwater fish from the land or a structure attached to land, may get the no-cost resident recreational saltwater shoreline fishing license. This license does NOT cover anyone fishing from a boat or from an island that they arrived at by boat. (shore, docks, jetties, piers, bridges, etc. ... also if you're wading as long as you can stand on the bottom)

Individuals who hold a recreational saltwater fishing license or any other license that includes recreational saltwater fishing privileges do not need a shoreline fishing license.

Also, you do not need a license if fishing from a chartered fishing boat.
