Summary: 

A three-year series of feeding trials was conducted to demonstrate the production, economic, and environmental advantages of the ASA-IM 80:20 pond technology and soy-based feed in comparison to a Chinese polyculture technology. Comparison trials conducted in 2006, 2007 and 2008 were conducted in a complex of six, 0.8-ha ponds in Jiangsu Province, China. Grass carp and silver carp were the fed and service species in the 80:20 system, with grass carp fed the extruded ASA-IM 32/3 feed, formulated on average with 45% soybean meal and 11% soy hulls. Grass, crucian, bighead and silver carps, plus wuchang bream, were stocked in the polyculture ponds, and were fed a 28% crude protein, local sinking feed together with fresh grass.
