Growth, mortality, health, food conversion, and condition of channel catfish (lctal- urus punctatus) were not significantly influenced by fish density, independently of water quality, in a multipass flow-through water system. The reuse of water in the triple-pass system caused a significant reduction in condition factor but not in the other measures of performance. Performance was unaffected by density. A maximum density index (relationship of fish weight and size to water volume) was not identified in this experiment; 5.41 kg fish/(m3 water x cm fish length) was the highest density index attained.
