Production of Red Tilapia in Ponds in Beijing with Soy-Maximized, Extruded Feed
Region: Northeast AsiaDownload
A feeding trial was conducted to demonstrate advanced fingerling to market growth performance of red tilapia in the Beijing, China region using a soy-maximized, all-plant protein feed. Fish were stocked in three, 2-mu (0.13-ha) ponds at a density of 1,000 red tilapia and 50 silver carp per mu (15,000 tilapia and 750 silver per ha). Red tilapia grew from approximately 150 g to an average weight of 495 g per fish in 75 days of feeding. Gross production averaged 484 kg/mu (7,260 kg/ha) for red tilapia and 52 kg/mu (788kg/ha) for silver carp. Average survival rates for red tilapia and silver carp were 97.8% and 98.7%, respectively. The soy-maximized feed, formulated to have 32% crude protein and 6% crude fat with soybean meal as the primary protein source, yielded an average estimated FCR with red tilapia of 1.51:1. Average net economic return was RMB 1,239 per mu ($2,249/ha). Average return on investment was 33%.
