The present invention relates to a hybrid produced through the hybridization of two strains belonging to the genus Bacillus subtilis, and a method for producing the hybrid, wherein the longtooth grouper, Epinephelusbruneus ) Female and giant grouper, Epinepheluslanceolatus ) male hybrids and hybrids between male and female bariatrix. The present invention can provide hybrids with high growth rate and excellent traits through hybridization of highly marketable probiotic with high-growth and marketable bivalves. Since the hybrid of the present invention has a rapid growth of the early ear, it is possible to solve the problem of the food creature, which is a big problem in the production of barley and fish, thereby contributing to revitalization of the domestic aquaculture industry.
