To provide various compositions for solving problems such that conventionally, various diseases of fishes are treated with antibiotics, vaccines and various immuno-augmenting agent, etc., but for the antibiotics, there are many problems in food hygiene such as the appearance of drug resistant bacteria, etc., on the other hand, for the vaccine and various immuno augmenting agent, many of them lack practicality in points of economic property, effectiveness, safety, labor or availability, etc., and also in the present fishery breeding, it is difficult to grow cultured fishes in a good efficiency caused by a hyper over-congested breeding.
This immuno-activating composition contains a tea tree essential oil. By feeding it to fishes, the immuno-activating effect, antibacterial effect, vaccine effect-augmenting effect and/or body-increasing effect of the composition are cumulatively or sinergistically exhibited, and it is possible to control various diseases of fishes and/or improve the breeding results of the fishes.
