Oxygen management improves channel catfish growth, FCR
Studies by the author demonstrated that until morning D.O. concentrations fell below 3.0 mg/L, feed consumption of channel catfish was not affected.

Blue catfish outproduce channel catfish under low-D.O. conditions
Although there is increasing interest in blue catfish, a potential disadvantage of the fish when compared to channel catfish is their reported poorer tolerance of low dissolved-oxygen concentrations.

Oxygen management at channel catfish hatcheries
In studies that compared performance of channel catfish hatcheries, eggs hatched six hours sooner with lower-oxygen incubation, but experienced lower survival.
