technical field [0001] The invention belongs to the technical field of feed, in particular to a feed for improving the immunity of aquatic animals and a preparation method thereof. Background technique [0002] Aquaculture is an advantageous industry in our country with broad prospects for development. In recent years, the aquaculture industry has grown rapidly. However, every time a major aquatic epidemic occurs, such as the recent epidemic of stealing death disease, gill rot disease, enteritis disease and other bacteria and viruses that cause high infection, high pathogenicity, and high death. The disease is a serious blow to my country's aquaculture industry. According to estimates, the direct loss caused by the disease and death of aquatic animals in my country is equivalent to about 60% of the increase in the total output value of the aquaculture industry.
