Fish of South Padre Island

Gafftopsail catfish

Habitat, season, identification and South Padre fishing context for gafftopsail catfish.

Meet the fish

Gafftopsail catfish (Bagre marinus) uses Surf, passes, bay channels and open bottom. This is a field guide to habitat and planning, not a promise that the species will be present or legal to retain on a particular trip.

Season and movement

Often more active in warm water but possible across seasons

Where it fits around South Padre

Fish a bottom rig in a surf trough or channel while keeping line and discarded bait contained

Fishing approach

Circle hooks and a controlled leader reduce deep hooking and make dehooking safer Common starting offerings include Cut bait, shrimp and other scent-producing natural baits

Handling and current rules

The dorsal and pectoral spines can cause serious punctures. Use a purpose-built dehooker or pliers and never kick or leave the fish on sand Open the current Texas saltwater regulations before fishing, then check any federal season or protected-species rule that applies to the water and vessel. Conditions, seasons and limits can change after this guide is published.
