A feeding trial was conducted in Taixing, Jiangsu Province, to demonstrate fingerling to market growth performance of GIFT tilapia using the ASA 80:20 pond production model and the ASA all- plant protein, soymeal-based growout feed. Fish were stocked in three, 5-mu ponds at a density of 1,000 tilapia and 100 silver carp per mu. Tilapia grew from 28 g to an average weight of 525 g per fish in 131 days of feeding. Gross production averaged 509 kg/mu for tilapia and 75 kg/mu for silver carp. Average survival rates for tilapia and silver carp were 97.5% and 98%, respectively. Average FCR for tilapia with the soy-based feed was 1.19:1. Feed cost per kilogram of fish weight gain was RMB 3.63. Net economic return was RMB 1,200 per mu. Average return on investment (ROI) was 36.4%. Tilapia demonstrated excellent growth performance, feed conversion efficiency and economic return with the ASA extruded, soymeal-based feed and 80:20 production technology in this trial.
