Telling them apart
Brown Bullhead Catfish vs Yellow Bullhead Catfish
Look at the chin barbels. A brown bullhead's are dark grey to black; a yellow bullhead's are white or cream. Nothing else is as quick or as reliable, because both fish vary enormously in body colour.

Why the difference matters
Body colour is the trap: a brown bullhead is frequently yellowish and a yellow bullhead is frequently brown, so the names actively mislead. The barbels take a second and settle it. Most states manage bullheads together under a generous or unlimited bag, so this is a knowing-your-water question rather than a legal one.
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exact water you are fishing before you keep a fish — we do not republish limits here, because a number that is a season out of date is worse than no number.
