Channel Catfish
Channel Catfish (Ictalurus punctatus) is a freshwater species. The first thing to check: a deeply forked tail, which separates it immediately from a flathead or a bullhead. The look-alike to rule out is Blue Catfish: blue cats have a straight-edged anal fin with 30 to 36 rays and never carry spots. Count the rays — colour alone is unreliable.

How to identify a Channel Catfish
- A deeply forked tail, which separates it immediately from a flathead or a bullhead.
- Scattered dark spots on the flanks of younger fish; large adults lose them and turn slate blue-grey.
- A rounded anal fin with 24 to 29 rays, and a clearly overhanging upper jaw.
If you would rather not work through a key on a wet deck, photograph the fish and let the app name it — you get the common and the scientific name back, and the record is filed before you release.
Fish it is mistaken for
| Species | How to tell them apart |
|---|---|
| Blue Catfish | Blue cats have a straight-edged anal fin with 30 to 36 rays and never carry spots. Count the rays — colour alone is unreliable. |
| Flathead Catfish | Flatheads have a squared-off, barely notched tail, a flat head and a protruding lower jaw. |

Where it lives
The most widely distributed catfish in North America — rivers, reservoirs, lakes and farm ponds across nearly every state. Holds in current breaks, holes and around cover.
Temperature
Feeds best between 70 and 85 °F; spawns at 75 to 80 °F.
The conditions that matter
Channel cats feed by scent, so they stay productive in the dark, in muddy water, and after rain when other species shut down. Rising, warming, coloured water after a summer storm is the classic trigger. Water temperature and clarity logged against catches map that reliably.
Global Fishing League records 18 weather and water readings against every catch automatically — tide stage, barometric pressure, water temperature, salinity, dissolved oxygen, chlorophyll, swell, current, moon phase and more, taken at your GPS position at the moment you log the fish. Over a season that turns a hunch about channel catfish into a pattern you can read.
See every reading recorded with a catch, or the guides to what each reading means.
Size limits, bag limits and seasons
Size limits, bag limits, slot limits and seasons are set by your state wildlife agency — and for many offshore and migratory species by federal regulators — and on many waters they differ from the statewide rule. They also change between seasons. Check the current regulations for the exact water you are fishing before you keep a fish — we do not republish limits here, because a number that is a season out of date is worse than no number.
What the app does do is make your side of it accurate: every catch carries a length measured from the photograph, a GPS position and a timestamp, exportable if you ever need to show your work for a tournament or a record claim. It is also what a Global Fishing League entry is built from — a record that verifies itself, without publishing where you caught the fish.
