Background technique [0002] Grass carp is one of the most popular freshwater fish. It is a typical herbivorous fish that inhabits rivers and lakes in plain areas. It generally likes to live in the middle and lower layers of water and areas with abundant aquatic grass near the shore. Because of its rapid growth and high nutritional value, it is one of the four major domestic fish in freshwater farming in China. Traditional grass carp farming is mainly based on green feed, which has a single nutrient component and cannot provide all the nutrients needed for the growth of grass carp, resulting in slow growth and low survival rate of grass carp, resulting in long breeding time and high breeding costs. Common diseases cannot be prevented and cured. Contents of the invention [0003] The invention provides a ...
