Recently, the "rice flower fish" in Anning City, Yunnan Province ushered in a bumper harvest. The fish feeds on aquatic insects and rice flowers in the field, and does not need extra feed. In addition to reducing pest and grass damage, the fish manure produced can also be used as fertilizer to achieve the maximum utilization of rice field resources.
