The invention provides a crassostrea gigas breeding method capable of increasing meat percentage, which comprises the following steps: S1, selection of parent crassostrea gigas: screening crassostrea gigas with golden yellow left shell color from a crassostrea gigas wild population as a basic population, and taking the golden yellow shell color and growth speed as breeding targets; S2, secondary optimization: reselecting 30-35 male and female crassostrea gigas with golden left shell and high meat percentage from offspring propagated by the parentcrassostrea gigas population selected in the S2, and selecting 30-35 male and female crassostrea gigas with golden left shell and high meat percentage from the offspring propagated by the parent crassostrea gigas population selected in the S2; S3, porpulation mating: performing mutual mating on the male and female crassostrea gigas selected in the S1; and S4, second breeding: performing male and female single-pair single mating propagation on the crassostrea gigas with offspring whaving golden yellow shell color and high growth speedin the S2. According to the crassostrea gigas breeding method capable of increasing meat percentage, the crassostrea gigas is formed through continuous breeding of at least four generations by adopting a mixed breeding technology combining family breeding and group breeding, and in the same breeding environment, compared with unbred crassostrea gigas, the average shell height, the average weight and the meat percentage of 15-month-old crassostrea gigas are improved respectively.
