The invention discloses an application of litsea cubeba essential oil in preparation of a product for preventing and treating streptococcus agalactiae disease of tilapia and/or improving weight gain rate of tilapia. The fish feed containing the litsea cubeba essential oil not only can improve the survival rate of tilapia infected with streptococcus agalactiae, but also can relieve pathological injury caused by streptococcus agalactiae; in addition, growth of fish can be promoted, and the feed conversion rate is increased. The litsea cubeba essential oil is easy to metabolize, does not easily generate drug resistance in organisms, does not cause environmental pollution, and meets the requirements of pollution-free sustainable development of modern aquaculture while preventing and treating streptococcus agalactiae diseases. 本发明公开了山苍子精油在制备用于防治罗非鱼无乳链球菌病和/或提高罗非鱼增重率的产品中的应用。含有山苍子精油的鱼饲料，不仅能够提高罗非鱼感染无乳链球菌后的存活率，还能够减轻无乳链球菌引起的病理损伤；另外还可以促进鱼的生长，提高饲料转化率。山苍子精油易代谢，在生物体内不易产生耐药性，也不会产生环境污染，在防治无乳链球菌病的同时，符合现代水产养殖无公害可持续发展的要求。
