Problems solved by technology

After drug treatment, the density of leeches on the surface of the fish body can be reduced, but the number of leeches increases sharply in about 7 to 10 days. Repeatedly, it increases the risk of infection of the surface of the East Star Spot, which greatly affects the growth and survival rate of the East Star Spot. , leech parasitic disease has become one of the important diseases in the East star spot breeding industry

Embodiment 1

[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.

[0027] (2) Disinfection treatment after the seed...

Abstract

The invention discloses a domestication and operation method for using money fish to prevent and control the parasitic disease of leech orientalis. In the method, the money fish is added to the oriental spotted leech culture pond for mixed culture to prevent and control the parasitic disease of leech orientalis. The present invention utilizes the omnivorous nature of money fish, prefers to eat invertebrates and gnaws on benthic algae, and domesticates the feeding habits of the eastern star spot to ingest compound feed, so as to eliminate the problem of the eastern star spot attacking the polycultured and smaller money fish; The prevention and control of leech parasitic disease is realized in the field of grouper aquaculture by the method of polyculture, which solves the problem of leech parasitic disease in the process of aquaculture of eastern star grouper.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a domestication and operation method for preventing and controlling the parasitic disease of the eastern star spotted leech by using the money fish. Background technique [0002] Plectropomus leopardus, scientific name Plectropomus leopardus, belongs to the order Perciformes, the family Pectidae, and the genus Pleopardus. It is native to the Dongsha Islands in eastern China. With the characteristics of good economic benefits, it has become the main species of land-based industrial farming in Hainan Province. The breeding output has reached 6,000 tons, and the output value has exceeded 1.5 billion yuan (Xu Chengxu, Chinese scientists deciphered the genome of East star spot, Aquatic Science and Technology Information, 2020, 47(1) :57). Money fish, the scientific name is Scatophagus argus, and the commercial name is golden drum fish. It is an omnivorous and bottom-feeding fish....
