How to catch Checkered puffer
Sphoeroides testudineus (Linnaeus, 1758)
About Checkered puffer fishing
The checkered puffer is a small, robust marine and brackish fish belonging to the family Tetraodontidae. It features a distinctive greenish upper body marked with pale intersecting lines forming concentric arcs and a whitish underside. Growing to a maximum length of nearly thirty-nine centimetres, this species relies on powerful fused beak-like teeth to crush hard-shelled benthic prey such as bivalves, gastropods, and crustaceans. It inhabits shallow coastal waters, bays, tidal creeks, seagrass beds, and mangrove swamps across the western Atlantic. When threatened, it can inflate itself with water or air to deter predators and frequently buries itself in sandy substrates when startled. While it holds no commercial value and is highly toxic if consumed, it is a familiar presence in inshore tropical and subtropical ecosystems.

When to fish for Checkered puffer
How to catch Checkered puffer
Tips for catching Checkered puffer
Anglers targeting inshore estuarine species often encounter the checkered puffer while bottom fishing over shallow sandy flats, seagrass meadows, or around mangrove roots. Because these fish possess immensely strong jaws capable of crushing heavy shells, standard terminal tackle should include short wire traces or heavy fluorocarbon leaders to prevent line chafing from their beak-like teeth. Small pieces of natural bait such as shrimp, strips of crab, or marine worms threaded onto stout hooks yield the most consistent results. Fishing is usually most productive during daylight hours when these benthic feeders actively comb the substrate for food. Handle any captured specimens with extreme care, as their flesh contains potent toxins and they will readily inflate when handled.
