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.

Texas

Texas — wind is the tide

Seven working bays, one printed table that is often a suggestion.

This coast runs from a brackish border estuary at Sabine to hypersaline rock at Baffin and the clear classroom of the Lower Laguna. The main event is the red. Trout live a foot deeper in the same bays. Flounder own the fall nights at the passes until the November closure. Winter belongs to drum and sheep on mud and granite. Corpus still sees a tarpon along the beach in mid-summer — Port A was once Tarpon, Texas — but that is a bay-boat job, not the skinny skiff. Do not fish Baffin like Rockport. Do not invent Rollover Pass; it was filled in 2019. Birds are GPS for trout. A hard norther empties the shoreline and stacks fish in the guts. Fly when the morning is honest. The gold spoon is what you came for when it is not.

August. Same heat, slightly shorter days. Trout still deep. Reds on the first moving water. Flounder are a September story — do not force them.

Louisiana

Louisiana — river, marsh, and the birdfoot

Wind and the Mississippi move more water than the printed tide.

Venice is the birdfoot — South and Southwest Pass, ponds on the west bank, bulls in the throats, school reds and trout inside, tarpon in the heat on the south passes. Grand Isle is a different desk: one inhabited barrier island, Caminada, Barataria, a state-park surf. Calcasieu is the Texas-border cousin under LDWF rules — same fish, different bag, not Sabine Lake. Reds are 4 a day, 18–27, none over 27. Trout are a slot. Flounder typically close Oct 15–Nov 30. Do not put a Texas tag on a Cameron fish.

August. Same heat. Venice tarpon thinning. Reds on the first moving water. Flounder are an October story here.

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.

August. Snook still closed — Boca through September, Jupiter through August. Bones at first light. Thunder by two.

Bahamas

Bahamas — bonefish country

Winter singles. Summer schools. Permit on the west sides when it lays down.

Andros is the capital — west-side white sand, schools by the acre, double-digit singles in the creeks, tarpon in the bights, permit May through October on the west side and outer cays. Abaco is Marls and ocean cays; verify what is actually running after Dorian. Grand Bahama is the thinking wade, a town to sleep in, big singles on foot. Eleuthera and the Exuma edge take more weather and give you more permit. Tides here are a modeled lunar clock, labeled as such — there is no NOAA gauge on these islands. Flats licensing has been tightening; verify before you wade. Jacks will find you. They are not why you booked the week.

August. Summer pattern holds. Smaller packs, honest shots, west-side permit if it lays down. Fly in the morning. Shade at noon.

Mexico

Mexico — two oceans, do not mix them

Yucatan is bones and sail. Baja is rooster and dorado. Neither is Texas.

Ascension Bay / Sian Ka’an is the Caribbean flat — Punta Allen, permit and bones, biosphere rules, a modeled tide. Isla Mujeres is the other Yucatan desk: winter sailfish on the current, summer mahi, a troll-and-kite day. Cross the country and you are in another fishery. East Cape is rooster in the wash and Gordo Banks when the blue water is in. La Paz is Espíritu Santo and El Bajo. CONAPESCA license. No NOAA gauge. Roosterfish does not live in the Gulf of Mexico.

August. Same heat. Gordo if the water is right. Ascension at dawn. Sail are a winter story.

Puerto Rico

Puerto Rico — urban tarpon, east-island flats

DNER water. Real NOAA gauges. Not a Keys copy and not FWC.

San Juan is Condado Lagoon and the bay — tarpon under the bridges, snook in the edges, a north-coast drop that is an offshore method. Vieques and Culebra are the Spanish Virgins: more sand, bones and permit, Mosquito Bay a reserve. La Parguera is the southwest mangrove desk, clocked to Magueyes 9759110. Blue marlin live in the story of this island; this brief will not invent a billfish on a lagoon. License is DNER. Do not paste a Jupiter snook closure onto Condado.

August. Same heat. Parguera trees at first light. The north drop if a storm missed you.

Seychelles

Seychelles — GT country

Indian Ocean atolls. Modeled tide. Lodge water on the outer rims.

Alphonse and St François are the photograph — giant trevally on the edge, bones and Indo-Pacific permit on the sand. Farquhar is the southern atoll, same fish, farther. Mahé is the public door: reef, park water, blue water, not the St François flat. There is no NOAA gauge. Tide is a labeled model. SFA license. Roosterfish does not live here. Atlantic jack crevalle does not either. You came for a GT.

August. Still the windy half. Plan Mahé or wait for October.
