Flathead Catfish
Pylodictis olivaris
Partially verified
Handling & regulations: Non-native to Virginia's Atlantic-slope tidal rivers (native range is the Tennessee, New, and Big Sandy watersheds) and considered invasive in many locations it now occupies, primarily due to illegal stockings — a real ecological concern (this species preys on other fish almost from hatching) alongside the region's other already-published non-native catfish species. It is illegal to stock fish into a public body of water without VDWR authorization. VDWR manages it as a sport fish under current size/creel limits — check the freshwater regulations link below before keeping one.
Identification
Flat, wide head with a projecting lower jaw (a real underbite) — the clearest field mark against the region's other large catfish, Barbels around the mouth; brown to olive-yellow coloring, Minimally notched, rounded-to-squared caudal fin — unlike blue/channel catfish's more deeply forked tail
Where this fish fits
Flathead Catfish is found across more than one water environment — this reflects real movement between them (e.g. a tidal migration or life-stage change), not uncertainty about where to look.
These are discovery categories describing where anglers realistically fish for this species, not a guarantee this project has confirmed regional access at every listed setting — see the linked locations below for this project's own actually-sourced spots.
- Typical season
- Most active at night, year-round where established; a serious rod/gear commitment for larger specimens.
- Habitats
- Freshwater rivers and lakes with overhead cover — undercut banks, submerged structure, and areas beneath trees where they ambush prey
- Food use
- Commonly eaten
Data not yet verified.
This site hasn't checked for a fish-consumption advisory covering this species yet. That is not the same as confirmed safe — check current official guidance before eating your catch.
Seasons, size limits, and possession limits change and vary by water body. Always check the current regulations at the current regulations page before you fish.
- Bait & lures
- Live bait fished near cover at night — this species is a nocturnal ambush predator, not usually a daytime sight-fished target
- Beginner difficulty
- Moderate
Part of this record is confirmed against an official source; other parts are not. See the notes below for exactly which.
Identification features, native-vs-introduced range, and the invasive/ecological-concern framing are directly confirmed via Virginia DWR's own Flathead Catfish species page as of 2026-08-16. That page states VDWR manages this species under current size/creel limits but does not itself list the specific numbers — check the general freshwater regulations link below. Season/bait notes beyond feeding behavior are general regional angling knowledge, not individually fact-checked.
