The invention relates to a Chinese 
herb medicinal additive for preventing 
tilapia fatty liver disease. The Chinese 
herb medicinal additive is characterized by comprising the following components in part by weight: 8 to 10 parts of 
mung bean, 1 to 3 parts of liquoric root, 1 to 3 parts of gentian, 1 to 3 parts of raw
