Channel Catfish Fry to Fingerling Growth Performance in Anhui with Soymeal-Based Feeds
Region: Northeast AsiaDownload
A 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.
