Key Words: Common carp, soy-based feed, LVHD cage technology, LVHD Cage Culture of Grass Carp with Soy-Based Feed in the Xintian Reservoir, Results of ASA-IM/China 2010 Feeding Demo 35-10-513 Zhou Zhang Jian and , American Soybean Association-InternationalMarketing 1016, Room 1 100004, P.R. China Introduction A feeding demonstration was jointly conducted by the American Soybean Association International Marketing (ASA-IM) program and the Wanzhou District Fishery Association, , to demonstrate the production performance of grass carp in Low Volume High Density (LVHD) cages with the ASA-IM 32/31 soymeal-based growout feed. The objective of the LVHD grass carp feeding demonstration was to demonstrate the production performance of grass carp with the ASA-IM formulated 32/3 extruded soybased feed without any supplementary grass in the Xintian Reservoir, Wanzhou District, Chongqing. PROTOCOLS Three, 4-m3 LVHD cages, 2-m square x 1-m deep, were constructed and deployed in Wanzhou Xintian Reservoir, , for the feeding demonstration. The cages were constructed of nylon netting and outfitted with opaque covers to reduce light and external motion stress. A feed enclosure approximately 1-m square in size was installed inside each cage. The feed enclosure extended sufficiently above and below the water line to contain extruded, floating feed pellets. Cage placement was in a single row, with 2-m spacing between cages to ensure adequate water exchange to each cage. 1The numerical component of the feed description refers to the percentage of protein and fat, respectively, in the ration, i.e. 32/3 indicates 32% crude protein and 3% crude fat.
