Abstract
Channel catfish were held in 18-cubic-foot pens from June 1 to Sept. 9 at stocking rates of 2, 4, 8, 12, 18, and 24 fish per pen. Mean weight per fish on Sept. 9 showed an inverse relationship with population density. Condition factors increased in all pens throughout the study. Fish in pens with 2, 4, and 8 fish were in better condition than those in more crowded pens after July 15. Growth of fish in the pen with 2 fish was similar to that in the open pond. Growth of channel catfish was greater in 2 ft. of water than at 4 and 6 ft. Low dissolved oxygen at 6 ft. caused the death of channel catfish by July 1.
