The invention discloses a sea fish ichthyophthiriasis prevention and treatment method. Fishes are susceptible to ichthyophthiriasis, and ichthyophthiriasis means white spots and mucus appearing on the gills, fins and skin of fishes, and can cause surface inflammation, necrosis, scale shedding and other symptoms on the bodies of fishes. By arranging net cages and choosing a fry release period, in combination with the feeding of multivitamin and immune polysaccharide for enhancing the resistance in the bodies of fishes and the treatment measures of feeding amoxicillin at the beginning of the disease infecting the fishes and hanging trichlorphon and sprinkling abamectin into the net cages in the outbreak period of ichthyophthiriasis, the sea fish ichthyophthiriasis prevention and treatment method prevents and controls ichthyophthiriasis. On one hand, the ichthyophthiriasis resistance of the sea fishes is enhanced, so the sea fishes cannot be easily diseased; moreover, since the fries are released early, at the beginning of ichthyophthiriasis outbreak, the fishes already grow up, the body resistance is enhanced, and therefore the fishes are less susceptible to ichthyophthiriasis; after the fishes are infected with ichthyophthiriasis, at the beginning of infection, the measures are adopted for treatment; consequently, prevention and treatment are combined, and the incidence rate of sea fish ichthyophthiriasis is greatly decreased and even almost eliminated by integrated control.
