Abstract Diploid (2n = 58) and triploid (3n = 87) channel catfish Ictalurus punctatus were reared indoors in circular fiberglass tanks equipped with rotating disc biofilters. Triploids were significantly heavier than diploids at 8 months of age and older. Triploid male and female channel catfish also had smaller gonads with altered histology. Triploids converted feed more efficiently, and may provide greater profits in commercial catfish culture than diploids.
