Phase-by-phase

Pre-Spawn

Trophy fishing window
65–70°F

Pre-spawn channel cats move from deep wintering areas to shallower water with cavity-spawning structure as temperatures climb through the high 60s.

Cut bait and stinkbait fishing on shallower structure increases productivity through May and June.

Spawn

Conservation window
70–84°F (peak 75–82°F)

Active spawning behavior. Males select and clean cavity nests, guard eggs and fry. Females visit nests, deposit eggs, and depart. Spawning typically occurs at night.

Channel catfish reproduce successfully in most waters and populations are robust. No widespread spawn-period closures.

Conservation context

Channel catfish reproduce successfully in most waters and populations are robust. No widespread spawn-period closures.

Post-Spawn

Recovery feeding
84–92°F (~14 days)

Males guard eggs and fry inside cavity nests for 2–3 weeks. Females depart immediately after spawning.

Post-spawn females feed aggressively; bottom fishing on shoreline structure with cut bait is effective.

Summer Pattern

Standard patterns
Above 92°F

Fish disperse to summer habitat and feeding patterns. Spawn cycle complete until following year.

Standard summer fishing tactics apply.
