Feeding trials in outdoor fish production ponds were conducted in 2008 by the American Soybean Association International Marketing (ASA-IM) program in cooperation with the Heilongjiang Provincial Fishery Extension Center and Shenyang Municipal Fishery Research Institute to show the feasibility of replacing fishmeal with soy protein concentrate (SPC) in the ASA-IM 36/7 1 fingerling feed for grass carp. The trials were conducted to demonstrate to fish farmers and feed millers in the northeastern region of China that an all-plant protein fingerling feed could be used to culture grass carp fingerlings. The ability to use all-plant protein feeds at the fingerling stage provides feed millers with an option to reduce feed cost associated with the rising price of fishmeal, 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.
