Blue Catfish
Ictalurus furcatus
For channel and blue catfish, their hybrids and subspecies, 25 (in any combination - only 10 can be 20 inches or greater in length). For flathead catfish, minimum length = 18 inches and daily bag limit = 5.
Identify your catch
Forked tail and a relatively straight-edged anal fin. Count anal-fin rays using an identification reference.
Habitat on Casa Blanca
Dam riprap, cattails and upper-lake dead trees provide cover; lake levels can fluctuate substantially.
Fishing approach
Lake guide guidance: TPWD suggests bass lures around reeds and riprap, bottom baits for catfish, and jigs or minnows around timber for crappie.
Fishing guidance describes documented approaches, not a promise of fish activity today.
No active lake-specific advisory or possession ban was named in the reviewed DSHS directory. This does not guarantee that fish are safe to eat.
Harvest permission and eating restrictions are separate.
