A feeding demonstration was conducted in Anjie City, Jiangxi Province, to demonstrate fingerling production of channel catfish using the ASA 80:20 pond production model and ASA soymeal-based fry and fingerling feeds. Catfish were stocked in three, 2.0-mu ponds at a density of 8,000 channel catfish per mu (120,000/ha) and 1,000 silver carp per mu (15,000/ha). Channel catfish grew from 1 g to an average weight of 39 g per fish in 109 days of feeding. Gross production averaged 269 kg/mu (4,038 kg/ha) for channel catfish and 50 kg/mu (750 kg/ha) for silver carp. Average survival rates for channel catfish and silver carp were 86.8% and 76.4%, respectively. Channel catfish FCR with the soymeal-based fry and fingerling feeds averaged 0.96:1. Average net economic return was RMB 1,646 per mu, for an average return on investment of 62.3%. Channel catfish exhibited good growth, feeding behavior and FCR with the ASA soymeal-based feed and 80:20 production technology.
