On This Water

Doctrine · not a honey-hole list

Seasonal fundamentals

When a coast, a type of water, and a fish actually line up. If you elected Texas on the list, this page opens on Texas — Seychelles stays off the board until you ask for it. Filter by region, method or habitat, and species. The year bar is peak versus present. Limits cite TPWD and FWC — verify before you keep one.

Florida

Florida — two coasts, do not mix them

Keys oceanside is bones and permit. Backcountry is reds and snook. Boca is the pass. Jupiter is the inlet.

Biscayne is the north end of the grand-slam stage. Key Largo is the first Key — Card Sound, Garden Cove, Pennekamp as the launch, not a secret flat. Adjacent SPAs are no-take. Islamorada is the mecca — Channel 5, oceanside banks, wrecks for permit that have seen every crab. Flamingo is a different country: reds and snook, not oceanside bones. Marathon and Key West stretch it south. Then the mainland: Boca Grande Pass is the spring tarpon stack, Charlotte Harbor the snook and reds — Gulf rules, not Atlantic. Jupiter is inlet snook and a beach tarpon, clocked to Lake Worth Pier. Snook closures differ by FWC region. FKNMS polygons are Keys-only. Do not headline Jupiter with a bonefish.

April. Tarpon month. Boca Grande Pass is why the rest of the year exists. Keys migration. Jupiter inlet. Permit still in play.

Type

Offshore

Trolling, the edge, and deep jigging. This is not the grass brief. Weedlines, humps, and named banks — Islamorada Hump, Flower Garden, Gordo, El Bajo, the Cancún sailfish current. Fly-and-teaser when the wind allows it. A heavy jig when it does not. Switch the method filter to Offshore or the engine will hide these marks on purpose. Roosterfish is Baja. Do not invent him on a Galveston morning.
