Blue Catfish
Ictalurus furcatus
For blue and channel catfish, no minimum length limit; daily bag and possession limit = 25 blue and channel catfish in any combination. In the 25-fish bag, no more than 5 fish 20 inches or greater in length may be retained, and no more than 1 of those can be 30 inches or longer.

Identify your catch
Forked tail and a relatively straight-edged anal fin. Count anal-fin rays using an identification reference.
Habitat on Lewisville
Flooded timber, small pondweed patches and creek-arm bridges provide cover.
Fishing approach
Lake guide guidance: Work bass near shoreline timber; look for summer white-bass schools and target bridge structure for crappie. Hybrids use main-lake ridges and humps.
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.
