Abstract
Black Bullheads, Ictalurus Melas (Rafinesque), were grown experimentally in two cage sizes from 25 July through 16 October, 1969. Little difference in fish growth between the two cage sizes was observed. Over 75% of total gain occurred while water temperatures were between 23 and 24°C. Better food conversion ratios were obtained when water temperature was above 23°C than when water temperature was below 23°C. Little difference in fish condition between the two cage sizes was observed. Fish were produced slightly more economically in the larger cages ($1.01/kg.) than in smaller cages ($1.05/kg.).
