Embodiment 1

[0022] 1. Install nanotubes 1 at the bottom of the pond, laying in a U-shape. The diameter of the nanotubes is 15mm. A 1.5kw oil-free air compressor 2 is connected to the bottom of the pond with a 1.5kw oil-free air compressor. The pond has an inlet 4 and a drain 3. According to the amount of dissolved oxygen in the water, switch on and off the oil-free air compressor, and the air flow in the nanotube is 0.1m 3 / hm, keep the dissolved oxygen in the water greater than 7mg / L.

[0023] 2. Methionine iodine immersion bath: drain the pond water to a depth of 0.2m, and soak the Masu salmon with methionine iodine, the dosage is 1g / m 3 The immersion time is 15min. After immersion, water is injected into the pond to a water level of 1.0m. If dead fish are found, they should be removed in time and buried deeply to prevent the spread of pathogens.

[0024] 3. Disinfection of breeding water: Dilute the decyl methyl ammonium bromide iodine solution and sprinkle the whole pond to make the pond w...

Embodiment 2

[0029] 1. Install nanotubes 1 at the bottom of the pond, laying in a U shape, the diameter of the nanotubes is 20mm, and a 3.0kw oil-free air compressor 2 is connected to the bottom of the pond. The pond has an inlet 4 and a drain 3. According to the amount of dissolved oxygen in the water, switch on and off the oil-free air compressor, the air flow in the nanotube is 0.3m 3 / hm, keep the dissolved oxygen in the water greater than 7mg / L.

[0030] 2. Methionine iodine bath: drain the pond water to a depth of 0.4m, and use methionine iodine to soak Masu salmon, the dosage is 1.5g / m 3 The immersion time is 30min. After immersion, water is injected into the pond to a water level of 1.3m. If dead fish are found, they should be removed in time and buried deeply to prevent the spread of pathogens.

[0031] 3. Disinfection of breeding water: Dilute the decyl methyl ammonium bromide iodine solution and sprinkle the whole pond to make the pond water concentration 0.1g / m 3 (Calculated as decy...

Embodiment 3

[0036] 1. Install nanotubes 1 at the bottom of the pond, laying in a U shape. The diameter of the nanotubes is 30mm. A 3.5kw oil-free air compressor 2 is connected to the bottom of the pond. The pond has an inlet 4 and a drain 3. According to the amount of dissolved oxygen in the water, switch on and off the oil-free air compressor, and the air flow in the nanotube is 0.6m 3 / hm, keep the dissolved oxygen in the water greater than 7mg / L.

[0037] 2. Methionine iodine immersion bath: drain the pond water to a depth of 0.5m, and use methionine iodine to soak Masu salmon, the dosage is 2g / m 3 , Soaking time is 40min, after soaking, pour water into the pond to the water level 1.5m. If dead fish are found, they should be fished out in time and buried deeply to prevent the spread of pathogens.

[0038] 3. Disinfection of breeding water: Dilute the decylmethylammonium bromide iodine solution and sprinkle the whole pond to make the pond water concentration 0.12g / m 3 (Calculated by decyl m...

Abstract

The invention discloses a compound medicine and a method for preventing and treating infectious haematopoietic necrosis of masu salmon, and belongs to the technical field of aquaculture. The medicineis prepared from the following raw materials in parts by weight: 17%-23% of honeysuckle, 15%-25% of radix scrophulariae, 12%-18% of wild chrysanthemum flower, 14%-16% of melia azedarach leaf, 7%-13% of bighead atractylodes rhizome, 5%-15% of dried ginger, 3%-7% of houttuynia cordata and 2%-8% of liquorice. The specific prevention and treatment method comprises the following steps: aeration of culture water, immersion bath of iodine methionine and disinfection of the culture water, and vitamin C, vitamin E and compound medicines need to be added into the daily ration feed at the same time. Themethod is simple to operate, does not influence the quality of aquatic products, and is widely applied to prevention and treatment of infectious hemopoietic 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 and a method for preventing and treating infectious hematopoietic organ necrosis of Masu salmon. Background technique [0002] Oncorhynchus masou (Oncorhynchus masou), Salmonidae, Salmon, Salmon, is an important economic fish. It is only distributed in Suifenhe and Tumen River in China and is currently endangered. Artificial breeding of fry is adopted for multiplication and release. During the breeding process of Masu salmon fry, infectious hematopoietic necrosis is more harmful. The pathogen is a rhabdovirus (Rhabdovirus). The disease is an acute infectious disease with a mortality rate of 90% to 100%. Harm to Masu salmon juveniles and juveniles. In recent years, the scale of masu salmon fry breeding has gradually increased, and the incidence rate has also increased. [0003] The existing method to prevent and treat Masu Hemaha infectious hematopo...
