A cage feeding trial was jointly conducted by the American Soybean Association International Marketing (ASA-IM) program and the Nanning Municipal Fishery Extension Center to evaluate the feasibility of culturing grass carp in cages with the ASA-IM soy-based grass carp feed. The feeding trial was conducted at Heng Xian Reservoir in Guangxi Province and compared grass carp growth in 4-m3 LVHD1 cages and 16-m3 traditional cages with feed only and with feed plus grass. The trial was designed to assess the feasibility of intensive grass carp culture in cages for application in reservoirs throughout China.
