Wuchang Bream Production with Soy-Based Feed and 80:20 Pond Technology: Shenyang
Region: Northeast AsiaDownload
A feeding demonstration was conducted in Shenyang, Liaoning Province, to demonstrate fingerling to market growth performance of wuchang bream using the ASA 80:20 pond production model and ASA soymeal-based growout feed. Fish were stocked in three, 2.2-mu ponds at a density of 1,000 wuchang bream and 100 silver carp per mu. Wuchang bream grew from 65 g to an average weight of 480 g per fish in 128 days of feeding. Gross production averaged 480 kg/mu for wuchang bream and 68 kg/mu for silver carp. Average survival rates for wuchang bream and silver carp were 99.9% and 100%, respectively. Wuchang bream FCR with the all-plant protein, soymeal-based feed averaged 1.10:1. Average net economic return was RMB 488 per mu at market prices of RMB 6/kg for wuchang bream and RMB 2/kg for silver carp. Return on investment (ROI) for the three demonstration ponds averaged 19.3%. Wuchang bream exhibited rapid growth, aggressive feeding behavior and efficient FCR with the ASA soymeal- based feed and 80:20 production technology.
