Pond Production of Common Carp in Shenyang with Soy-Based Feed
Region: Northeast AsiaDownload
A feeding trial was conducted in Shenyang, Liaoning Province, to demonstrate fingerling to market growth performance of common carp using the ASA 80:20 pond production model and the ASA all-plant protein, soymeal-based growout feed. Fish were stocked in three, 2.4-mu ponds at a density of 700 common carp and 100 silver carp per mu. Common carp grew from 80 g to an average weight of 668 g per fish in 99 days of feeding. Gross production averaged 466 kg/mu for common carp and 79 kg/mu for silver carp. Average survival rates for common carp and silver carp were 99.6% and 100%, respectively. Common carp FCR with the soymeal-based feeds averaged 1.46:1. Average net economic return was RMB 371 per mu, for an average return on investment (ROI) of 15.4%. Results of the feeding demonstration showed that common carp exhibited good growth performance and FCR with the ASA soymeal-based feed and 80:20 production technology. Common carp reached the target market size in just 99 days and had good quality and market acceptance. The use of extruded, floating feed significantly reduced labor costs, lowered fish FCR, improved water quality, and allowed production of healthy and disease-free fish without the use of drugs or chemicals.
