Channel Catfish Fry to Fingerling Growth Performance in Anhui with Soymeal-Based Feeds
Category: Aquaculture
Region: Northeast Asia
DownloadA feeding demonstration trial was conducted at the Jiao Gang Hu Fish Farm in Huainan, Anhui Province, to demonstrate fry to fingerling growth performance of channel catfish using the ASA 80:20 pond production model and soymeal-based fry and fingerling feeds. Fish were stocked in three, 3-mu ponds at a densities of 8,000 channel catfish fry and 1,000 silver carp fry per mu. Channel catfish grew from 1.6 g to an average of 49.3 g per fish in 101 days of feeding. Gross production averaged 353.5 kg/mu for channel catfish and 50.1 kg/mu for silver carp. Average survival rates for channel catfish and silver carp were 89.4% and 81.5%, respectively. Channel catfish FCR for the combination of ASA 41/11 fry and 36/7 fingerling feeds was 0.93:1. Average net economic return was RMB 5,665/mu per mu, and average ROI was 110.7%. Channel catfish exhibited good growth, feed conversion, survival and economic return with the ASA 80:20 pond technology and soymeal-based feeds. Compared to normal production of channel catfish at the Jiao Gang Hu Fish Farm, fish survival was reported to have increased by 25-30%, FCR was reduced by 100%, and ROI was increased by >60% with the ASA technologies and feeds.
