Shortnose Gar
The smallest and most overlooked member of the North American gar clan, shortnose gar haunt the slow backwaters, oxbows, and sluggish river bends of the Mississippi and Missouri basins.
They've evolved a vascularized swim bladder that lets them gulp air at the surface, so they thrive in warm, silty water that suffocates other fish.
Scientific Name: Lepisosteus platostomus
Also known as Billy Gar, Stub-nose Gar, Short-billed Gar, Duck-billed Gar
- Long, cylindrical body sheathed in interlocking diamond-shaped ganoid scales — armor plating that runs in oblique rows down the flanks, 60–64 along the lateral line.
- The defining feature is a short, broad snout — the width fits into its length only 6–10 times — set with a single row of conical teeth, giving it a stubby, duck-billed profile compared to other gars.
- Brown to olive on the back, fading to yellow flanks and a white belly; juveniles under ten inches carry a bold black midline stripe. Any spots on the unpaired fins are vague, never the crisp dots seen on spotted gar.
- Typical adults run 24–28 inches and 2–4 pounds; an exceptional fish stretches to 35 inches, and the IGFA all-tackle record stands at 7 lb 8 oz.
What to know
Habitat Distribution
- Native across the Mississippi and Missouri river basins, from the Gulf Coast north through the central Plains and into the Great Lakes fringe — a range that covers most of the central US in slow, warm-water systems.
- Slow rivers, quiet pools, oxbow lakes, swamps, and the wave-washed shoals of large impoundments — anywhere the current eases and the water sits warm.
- More tolerant of turbid water than any other North American gar, and able to survive in seasonally anoxic backwaters by surfacing to gulp air.
- At the western edge of the range, populations thin out and become localized; in some Great Lakes states the species hangs on in marginal habitat and is locally protected.
Specific Spots
- Surface-oriented almost always — fish hold within the top six feet of water and roll visibly to gulp air, which is the single best way to locate them.
- Downed timber, root tangles, and the edges of dense weed beds in sluggish river bends, impoundment coves, and oxbows give them ambush lanes onto baitfish moving past.
- In summer they pile into shallow, warm backwaters that other fish abandon — the warmer and more stagnant, the more gar.
- When rivers flood, fish push out of the main channel into newly inundated floodplain to chase displaced prey.
Shortnose Gar FAQ
Answers from onWater's species guide.
What are the best lures and bait for Shortnose Gar?
The frayed nylon rope lure, 4–6 inches of unraveled 3/8 to 1/2 inch nylon rope on a swivel, is the single most effective method. It tangles in their teeth instead of relying on hook penetration. Wait 5–10 seconds after the strike before applying any pressure.
What flies work for Shortnose Gar?
The hookless (or lightly-hooked) nylon rope fly is the standard, frayed nylon fibers that snag in the gar's needle teeth and dramatically improve your hookup rate over a conventional fly.
What do Shortnose Gar eat?
Mostly small fish, whatever's locally abundant, taken with a slow stalk and a quick sideways snap of the jaw, then swallowed headfirst once the prey stops fighting.
Where do Shortnose Gar live?
Native across the Mississippi and Missouri river basins, from the Gulf Coast north through the central Plains and into the Great Lakes fringe, a range that covers most of the central US in slow, warm-water systems.
