Daily variation in feed consumption by channel catfish

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.
