Flathead Catfish

Flathead Catfish

Flathead catfish are not native to New York but have been documented in the state's waters, particularly in the Upper Delaware River system.

First collected in the Delaware River system in 1999 at Blue Marsh reservoir on the Schuylkill River, they are now established from the New York State border down to Philadelphia.

These invasive predators are apex predators that consume primarily live prey throughout their lives.

Scientific Name: Pylodictis olivaris

Physical Characteristics:

Easily identified by their distinctive flattened head, prominent underbite with the lower jaw extending past the upper jaw, and rounded (not forked) tail fin. They have olive to yellowish-brown coloration with dark mottling above and lighter coloration below.

Flathead Catfish FAQ

Answers from onWater's species guide.

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

Small to medium-sized sunfish, bluegills, bullheads, or suckers work best, as flatheads strongly prefer live, struggling prey over cut bait or stink baits.

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

Fish from late spring through fall, avoiding the spawning period in late spring/early summer (May-June) when water reaches 72-77°F. Fall (September-October) offers excellent fishing as flatheads feed heavily before winter.

How do you catch Flathead Catfish in New York?

Use live bait almost exclusively. Fish adjacent to deeper water (15+ feet) and be prepared to move frequently, spending only 15-30 minutes per spot. Present live bait near structure where these ambush predators wait for prey.
