Problems solved by technology

[0003] The existing method is to use chemical disinfectant to spray in the water body of cultivating Masuha haematopoietic organ necrosis to the prevention and treatment of Masohaha infectious hematopoietic organ necrosis. Secondary injury, the prevention and control efficiency is very low
It is reported that the control method for rainbow trout species is to inject infectious hematopoietic organ necrosis immune inactivated vaccine, which has a certain effect on rainbow trout, but has not been applied to masu salmon, and the injection method is performed in each fish. On the body of the fish, the fry are small and precise injection is required. The operation is difficult, labor-intensive and cumbersome, and it is not easy to apply and promote.

Embodiment 1

[0023] 1. Nanotubes 1 are arranged at the bottom of the pond, laid in a U shape, and the diameter of the nanotubes is 15mm. A 1.5kw oil-free lubricated air compressor 2 is provided outside the pond to connect with the nanotubes at the bottom of the pond. The pond is provided with a water inlet 4 and a water outlet 3 . According to the amount of dissolved oxygen in the water, switch on the oil-free lubricated air compressor, and the air flow in the nanotube is 0.1m 3 / hm, keep the dissolved oxygen in water greater than 7mg / L.

[0024] 2. Methionine iodine immersion bath: drain the pond water to a depth of 0.2m, and soak the masu salmon with methionine iodine at a dosage of 1g / m 3 , The immersion time is 15min, after immersion, inject water into the pond to the water level of 1.0m, if any sick and dead fish are found, remove them in time and bury them deeply to prevent the spread of pathogens.

Embodiment 2

[0030] 1. Nanotubes 1 are arranged at the bottom of the pond, laid in a U shape, the diameter of the nanotubes is 20mm, and a 3.0kw oil-free lubricated air compressor 2 is arranged outside the pond to connect with the nanotubes at the bottom of the pond. The pond is provided with a water inlet 4 and a water outlet 3 . According to the amount of dissolved oxygen in the water, switch on the oil-free lubricated air compressor, and the air flow in the nanotube is 0.3m 3 / hm, keep the dissolved oxygen in water greater than 7mg / L.

[0031] 2. Methionine iodine immersion bath: drain the pond water to a depth of 0.4m, and soak the masu salmon with methionine iodine at a dosage of 1.5g / m 3 , The immersion time is 30min. After immersion, pour water into the pond to the water level of 1.3m. If sick and dead fish are found, they should be fished out in time and buried deep to prevent the spread of pathogens.

Abstract

The invention relates to a compound medicine and method for preventing and treating infectious hematopoietic organ necrosis of Masu salmon, belonging to the technical field of aquaculture; 15%~25%, wild chrysanthemum 12%~18%, neem leaves 14%~16%, Atractylodes macrocephala 7%~13%, dried ginger 5%~15%, Houttuynia cordata 3%~7%, licorice 2%~ 8%; specific control methods include aeration of breeding water, methionine iodine bath and disinfection of breeding water, and vitamin C, vitamin E and compound drugs need to be added to the diet. The invention has simple operation, does not affect the quality of aquatic products, and is widely applicable to the prevention and treatment of infectious hematopoietic necrosis of masu salmon.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a compound medicine for cultivating Masu salmon and a method thereof. Background technique [0002] Masu salmon (Oncorhynchus masou), Salmoniformes, salmon feed, salmon genus, is an important economic fish. It is only distributed in Suifen River and Tumen River in China, and it is currently endangered. Artificial breeding of fish fry is used for multiplication and release. In the breeding process of masu salmon fry, infectious hematopoietic necrosis disease is more harmful. The pathogen is a rhabdovirus (Rhabdovirus). This disease is an acute infectious disease with a mortality rate as high as 90% to 100%. Harm Masu salmon juveniles and juveniles. In recent years, the breeding scale of masu salmon fry has gradually increased, and the incidence rate has also increased. [0003] The existing method is to use chemical disinfectant to spray in the water body of cul...
