Flathead Catfish

Flathead Catfish

Flathead catfish are non-native to Nevada, with documented occurrences reported in the Ivanpah-Pahrump Valleys as of 2007. These large, predatory catfish are primarily nocturnal ambush predators.

Scientific Name: Pylodictis olivaris

Physical Characteristics:

Easily identified by their distinctive flattened head, olive-colored body with mottled patterns, and pronounced underbite with the lower jaw extending well past the upper jaw.

What to know

Habitat Distribution

Prefer deep river segments, reservoir pools, and areas with slow-moving water.

Key Locations

Ivanpah-Pahrump Valleys

Specific Spots

Target deep holes with heavy cover like submerged logs, rock piles, brush piles, and undercut banks during the day. Look for structures on river bends with drop-offs and deeper water upstream. At night, fish creek channel edges, tributary mouths, and underwater humps in more open water.

Flathead Catfish FAQ

Answers from onWater's species guide.

What are the best lures and bait for Flathead Catfish in Nevada?

Live bait - bluegills, sunfish, small carp, bullheads, creek chubs, shiners, and suckers are all effective, with larger baits (8-10 inches) producing bigger fish.

When is the best time to fish for Flathead Catfish in Nevada?

Late spring through fall, with September and October being peak season. March through May offers excellent pre-spawn action. Winter fishing can be productive in deep holes but requires more effort.

How do you catch Flathead Catfish in Nevada?

Use Santee Cooper or Carolina rigs that allow natural bait movement. In shallow water (3-5 feet), fish beneath large floats with bait suspended 6-8 inches shorter than water depth. Practice patience as flatheads can be slow to bite, and maintain multiple rods in different locations.

What do Flathead Catfish eat?

Prefer live prey throughout their lives, feeding on fish, crayfish, insects, and almost anything that moves and creates vibration. Juvenile flatheads consume crustaceans and insect larvae until reaching about 4 inches, then transition to crayfish and small fish.
