Feeding Of Channel Catfish Fingerlings In Mild And Severe Winters In Mississippi

A feeding study with channel catfish fingerlings (Ictalurus punctatus) was conducted in the winters 1975-76 and 1977-78, a mild and severe winter, respectively. In both years, fish in 3 ponds were fed 3 days per week and fish in 3 ponds were fed 6 days per week. In the 1975 study, fish fed 3 and 6 days per week averaged 10% and 45% weight gain with a mean feed conversion of 2.63 and 2.90, respectively; fish fed 6 days per week had significantly (p < .10) greater weight gains than the fish fed 3 days per week. In 1977 fish fed 3 days per week gained an average of24% and had a mean conversion of 1.98. Fish fed 6 times per week had an average weight gain of 29% and a mean feed conversion of 2.50. This was not significantly (P < .10) different than the fish fed 3 days per week.
