Abstract
The influence of shelter and two feeding methods on the growth, yield, survival, and feed conversion of channel catfish (Ictalurus punctatus) was investigated. Channel catfish fry (mean, 0.035 g) were stocked into earthen ponds at 378,600 fish/hectare. Six 400-m2 ponds had a l-m × 1.5-m floating rubber mat as a shelter and six had no shelter. Feed was given in the form of moist, 10-cm-diameter balls or as a dry crumbled feed twice a day at an initial rate of 5 kg/hectare. The greatest net yield of fingerlings was obtained where no shelter was provided and feed was given as crumbles. Average net yield was 116.9 kg/hectare greater in ponds without shelter. Ponds receiving a crumbled feed had a 113.7 kg/hectare greater net yield than those given a moist feed ball. Survival was 18.9 percentage points greater in ponds without shelter.Keywords
