[0025] A domestication and operation method for preventing and controlling the parasitic disease of the eastern star spotted leech by using money fish, comprising the following steps:
[0026] (1) Cultivation of seedlings of East Star Spot: According to the conventional method of cultivating grouper seedlings, grow East Star Spot in an outdoor soil pond to 2.5-4.0 cm. After the metamorphosis of East Star Spot is complete and the fin rays are completely shrunk, East Star Spot can be caught according to conventional methods. Seedlings are transferred to indoor cement ponds for subsequent cultivation; the aquaculture water bodies in the soil ponds and cement ponds are both seawater, and the seawater used needs to be filtered through sand. After filtration, the water body is clear and free of impurities; the specifications of the cement pond are: 1.2 meters high, The area is 5-15 square meters, and the breeding water is 5-15 tons.
