Zusammenfassung:	The invention belongs to the technical field of microorganisms, and particularly relates to schizochytrium limacinum with high yield of EPA and application of the schizochytrium limacinum. According to the invention, the schizochytrium limacinum for preparing the EPA through fermentation is obtained through ultraviolet mutagenesis and selective culture screening, and the strain name is Schizochytrium sp.ALS01. The invention also discloses a preparation method of the schizochytrium limacinum for preparing the EPA through fermentation. The schizochytrium limacinum ALS01 can produce high-yield EPA through fermentation of a common culture medium, the EPA content reaches up to 10.11%, meanwhile, high-yield DHA can be achieved, the DHA content can reach 46.02%, and the schizochytrium limacinum ALS01 is an ideal microbial resource for producing various omega-3 fatty acids. Meanwhile, the schizochytrium limacinum ALS01 with high yield of EPA and DHA not only can reduce the production cost of EPA and DHA, but also can
