A low pressure, high volume, forced-air method of incubation was evaluated for eggs of channel catfish, "Ictarlurus punctatus," and channel catfish ♀ X blue catfish, "I. furcatus," ♂ hybrids and was compared to the traditional paddle-type incubation method. No significant difference was observed in hatching percentage, survival, or weight of sac-fry and swim-up fry or in total weight after 21 days of feeding for 10 egg masses that were divided equally and incubated with paddles or forced air. The forced-air method was inexpensive, safe, quiet, and as effective as paddle-type aeration.
