A feeding demonstration was conducted in 2010 by the American Soybean Association International Marketing (ASA-IM) program in cooperation with the Wujiang Aquaculture Co. Ltd., Jiangsu Province to demonstrate the feasibility of replacing fishmeal with soy protein concentrate (SPC) in the ASA-IM 36/71 fingerling feed for grass carp. The demonstration was conducted to demonstrate to fish farmers and feed millers in the Yangtze River Delta that an all-plant protein fingerling feed would yield the equivalent tilapia production and performance as a high fishmeal inclusion feed. The ability to use all-plant protein feeds at the fingerling stage provides feed millers with an option to formulate without fishmeal, which is limited in availability with increasing price, as well as a means to improve industry sustainability by providing a fingerling feed in which the majority of protein is supplied from renewable plant sources.
