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.

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.

May. Baja turns on. Dorado, tuna on Gordo, rooster in the wash. Yucatan flats still honest if you beat the heat.

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.
