The invention discloses phaffia rhodozyma GOY1 for improving the body color of aquatic animals and a preparation method and application of a culture of the phaffia rhodozyma GOY1. The phaffia rhodozyma is classified and named as phaffia rhodozyma, and the preservation number of the phaffia rhodozyma is CGMCC (China General Microbiological Culture Collection Center) No. 22504. The preparation method of the phaffia rhodozyma GOY1 culture comprises the following steps: culture of a phaffia rhodozyma GOY1 seed solution, pre-enzymolysis of a solid culture medium, solid culture, cell wall breaking and drying. The phaffia rhodozyma GOY1 and the culture thereof can be used for preparing an aquaculture animal feed additive, and can improve the weight gain rate and the survival rate of the penaeus vannamei boone, reduce the feed coefficient and improve the body color of the penaeus vannamei boone, so that the non-specific immunity of the penaeus vannamei boone is improved, and the intestinal flora structure is improved
