Alligator Gar Fishing Guide

The alligator gar (Atractosteus spatula) is the largest purely freshwater fish in North America by weight, with verified specimens exceeding 8 feet in length and 300 pounds. Its fearsome appearance — diamond-shaped ganoid scales hard enough to deflect arrowheads, a broad alligator-like snout with two rows of large teeth, and an overall prehistoric look — reflects an ancient lineage with fossils nearly identical to modern specimens from 100 million years ago. Alligator gar once ranged throughout the Mississippi basin and Gulf Coast drainages, but overfishing, habitat loss, and misguided eradication campaigns eliminated them from much of their historic range. Conservation and restoration efforts in Texas, Louisiana, and Mississippi have stabilized populations, and catch-and-release fisheries targeting large alligator gar have emerged as a significant destination fishery. CAUTION: gar eggs (roe) are highly toxic to humans and pets — never consume them.

Alligator Gar is a freshwater species.

Habitat

Large, warm, slow-moving rivers, reservoirs, and coastal bays from Texas to Florida along the Gulf Coast and up the Mississippi drainage into the Midwest. Strongly prefers shallow, warm backwaters and connected floodplain lakes; uses the swim bladder to breathe air and can survive in extremely oxygen-depleted water.

Diet

Opportunistic predator consuming fish, waterfowl, small mammals, and carrion; primarily ambushes prey from a motionless floating or near-bottom position. Large gar use a sideways slashing strike to stun fish before eating them — a behavior clearly visible to anglers watching them feed near the surface.
