In 1998, the author took the opposite approach and rented ten mu of land to introduce a new forage hybrid of Guangxi Forage Breeding Institute - corn for hybrid forages; fish ponds were fed with sufficient forage to reduce 80% of the concentrate investment, due to greatly reduce the cost of farming, fish prices in the situation still achieved considerable economic benefits.
