Abstract
Abstract The feasibility of rearing rainbow trout (Oncorhynchus mykiss) with overwintering fingerling channel catfish (Ictalurus punctatus) at one of two densities was examined. Individual weight gain, net production, and feed conversion were better for rainbow trout in monoculture than in either polyculture treatment. There was a significant difference in growth but not in survival of channel catfish polycultured at low and high densities with rainbow trout.
