Pond feeding trials conducted cooperatively by the American Soybean Association International Marketing (ASA-IM) program and the Shenyang Municipal Fishery Research Institute demonstrated the economic value of a soy-based, low fat and high fiber diet for producing two and three-year old grass carp. Feeding trials were conducted in 2004 and 2005 to demonstrate fish performance on the soy-based feed and the resulting economic value to fish farmers in the northeastern region of China.
