Effect Of Vitamin Fortification In Auburn No. 2 Fish Feed

Vitamin fortification of the Auburn No.2 pelleted fish feed increased net production of channel catfish an average of 19.3 percent in feeding tests conducted in replicated earthen ponds between April 13 and November 9, 1970. A stocking density of 4,000 fingerlings acre was used and the fish were fed 6 days per week. In comparison to a second commercial catfish feed containing identical v\\tamin fortification the fortified Auburn No.2 feed produced an increase in net production of 39.5 percent. Feed conversion, gain per day and average weight of fish at harvest were all superior with the fortified Auburn No.2 feed when compared to the other two rations.
