Daily Variation in Feed Consumption by Channel Catfish

Abstract

Daily feed consumption by 0.09-lb channel catfish (Ictalurus punctatus) stocked at 50 and 75 lb offish per 0.25-acre pond, and by 0.57-lb channel catfish stocked at 100 and 200 lb offish per 0.25-acre pond, was measured for 157 d. Demand feeders were used to determine feed consumption. Feed consumption routinely varied, on successive days, an average of 61 and 31%, for the 0.57-lb fish stocked at the higher and lower rates, respectively, and 58% for both stocking densities of the 0.09-lb fish.
