  abstract: The interaction of water temperature and dietary energy/protein (DE/P) ratio on the growth, voluntary feed consumption, and body composition of channel catfish (Ictalurus punctatus) was examined experimentally, and a simulation model that includes functional relationships representing the effects of water temperature, DE/P ratio and their interaction on catfish growth was developed. Fingerling channel catfish, acclimated and maintained at a temperature of 23, 28, or 33°C, were fed for 12 weeks on one of six diets that contained 25 or 35 percent crude protein and had DE/P ratios of 6.0, 8.4 or 10.6 (kcal/g). Fish fed the 35 percent crude protein diet with a DE/P ratio of either 8.4 or 10.6 exhibited the fastest growth. At 28°C fish growth and protein deposition were faster than at the other temperatures. At 23°C fish growth was supressed on the high protein-low DE/P ratio (6.0) diet. Voluntary feed consumption was inversely related to the dietary energy level at each temperature. Feed consumption was lowest at 23°C, but was not different at 28 and 33°C for fish fed to satiation twice daily. Whole body protein, ash, and moisture were inversely related to DE/P ratio, while whole body fat was directly related to DE/P ratio at each temperature. The simulation model was developed by modifying a general bioenergetics model of fish growth proposed by Cuenco et al. (1985a) to include new functional relationships representing the effects of crude protein and DE/P ratio requirements on consumption and assimilation by channel catfish. The simulation model predicted growth and feed consumption near buy slightly above the observed experimental results.
