Alligator Gar

Atractosteus spatula

Also known as

  • Gator Gar US
  • Gator US
  • Great Gar US
  • Manjuari US

Identification

Massive prehistoric apex predator with primitive armoured build. Shocking short-range acceleration for the size — tires within minutes of explosive runs. Females larger and deeper than males. Across southern US rivers, oxbows, and brackish estuaries.

  • Brown to olive-green back fading to a yellowish-white belly with dark spots on the rear fins
  • Hard diamond-shaped ganoid scales forming rigid armour plating across the entire body
  • Broad flattened alligator-like snout with double rows of large sharp teeth on the upper jaw
  • Back fin, tail fin, and bottom fin all clustered far back near the tail base

  • Rivers
  • Lakes
  • Wetlands

Behaviour

An apex ambush piscivore that takes shockingly large prey — mature fish documented eating prey up to a third of their own length. Diet is dominated by shad, mullet, common carp, and buffalo; waterfowl and small mammals are taken opportunistically. Breathes atmospheric air, surfacing to gulp in warm low-oxygen water — a key sight-fishing tell. Dawn-dusk and nocturnal feeders with peak activity above 25°C (77°F). Adults solitary; juveniles school in vegetated shallows.

Diet: Baitfish, Shad, Mullet, Common Carp, Buffalo

How it's caught

Line Fishing

Bottom Fishing

The dominant rod-and-reel method. Fish 30-60cm chunks of fresh-cut shad, mullet, common carp, or buffalo on a Carolina-rig sliding sinker (60-115g) over deep holes, channel edges, and current breaks. 5/0-8/0 circle hooks with bronze (corrodible) finish — the bony beak rejects most J-hook sets. Free-spool the take and count 20-40 seconds before swinging. 80-150lb braid with a 100-200lb wire or hard mono leader. Fights run 30-60 minutes on quality fish.

Live Lining

Drift or slow-troll a hooked-through-the-back live shad, mullet, or large shiner under a tethered jug or balloon along structure edges, oxbow mouths, and tail-water seams. Live bait moves naturally and triggers committed takes from the largest fish in a system — most state-record fish come on live bait. Same circle-hook and wire-leader rigging as bottom fishing.

Float Fishing

Suspend cut bait or a live shad 60-150cm under a heavy slip float in slack-water oxbows, sloughs, and flooded backwater where fish patrol shallow. Best on calm summer days when fish gulp air at the surface and patrol predictable lanes. Same heavy-leader rigging.

Bow Fishing

A major harvest method in Texas, Louisiana, Arkansas, and Mississippi — most state-record bowfishing fish come from elevated platforms on shallow-draft boats running flooded timber, oxbows, and spawning flats. Aim 15-30cm low for refraction; effective range 4-8m. Night shooting under high-output LED arrays is the dominant tournament format. Heavy 200lb-plus arrow line and a barbed/grappling point are mandatory for fish above 1.5m.
