The Flathead catfish (Pylodictis olivaris), also called the yellow cat, opelousas, mud cat and shovelhead cat, are large North American freshwater catfish.

Flathead catfish are most closely related to the Satan genus of fish. They grow to a lengh of c. 155 cm and may weigh up to 56 kg. Their maximum recorded lifespan is 20 years. Males are mature from c. 16 cm and 4 years of age while females mature from c. 18 cm and 5 years of age, but may mature as late as 10 years.

Inhabiting deep pools, lakes, and large slow-moving rivers, Flathead catfish are popular among anglers; their flesh is widely regarded as the tastiest of the catfishes. Their size also make the Flatheads effective subjects of public aquaria. Like most catfish, Flatheads are benthic feeders and are not picky.

Sport fishing for flathead catfish using rod and reel can be an exciting pastime. Anglers target this species in a variety of waterways including small rivers (barely large enough for a canoe), large rivers (such as the Missouri and Mississippi Rivers), and reservoirs. A common element of flathead catfish location is submerged wood cover such as logs and rootwads which often collect at bends in rivers. A good flathead spot usually also includes relatively deep water compared to the rest of a particular section of river, a moderate amount of current, and access to plentiful baitfish such as river herring, shad, carp, drum, panfish, or suckers. Anglers targeting large flathead catfish usually use stout tackle such as medium-heavy or heavy action rods from 6–10 feet (1.8–3.0 meters) in length with large line-capacity reels and line ranging from 20–80 pound (90–360 N, 9–36 kgf) test breaking strength. Generally large live baits are preferred such as river herring, shad, sunfish, suckers, carp, goldfish, drum, and bullheads ranging from 5–12 inches (12–30 cm) in length. Sometimes nearly as much time and effort is spent catching baitfish ahead of time as is spent fishing for flatheads. While not as numerous as other catfish species, catching a large flathead catfish (over 20 pounds) usually makes the effort worthwhile to an avid catfisherman. Flathead catfishing often takes place at night either from a boat or from shore once a catfisherman or woman has identified a likely looking flathead spot. The pound-force is a non-SI unit of force or weight (properly abbreviated lbf or lbf).

Spawning occurs in late June and early July, the nests made in areas with submerged logs and other debris. The males, who also build the nests, fiercely and tirelessly defend and fan the clutch. The size of the clutch varies proportionately to the size of the female; an average of 2,640 eggs per kilogram of fish are laid.


The fry frequent shallow areas with rocky and sandy substrates where they feed on insects and worms such as annelids and polychaetes. Young flatheads are also cannibalistic, a fact which has largely precluded their presence in aquaculture. Classes and subclasses Class Polychaeta      (paraphyletic?)
