Embodiment 1

[0011] Embodiment 1, using the acid-base titration method, it is 80mg CaCO2 to determine the total alkalinity of the shrimp breeding disease pond 3 / L, the first step, every 667m 3 Add 20kg sodium bicarbonate and 20kg dolomite powder to the water body to increase the alkalinity to 100-110mg CaCO 3 / L, the second step, application: continuously apply the mixture of ochre powder and vitamin C for 5 days, wherein the amount of ochre powder is 10kg / 667m 3 , the amount of vitamin C is 0.2kg / 667m 3 , Sprinkle once a day, and sprinkle the whole pond; the third step is to increase oxygen, and turn on the aerator throughout the day during the treatment; the fourth step is to feed, and to feed normally according to the feeding situation of the prawns during the treatment.

Embodiment 2

[0012] Embodiment 2, use the acid-base titration method to measure the total alkalinity of the prawn breeding morbidity pond to be 90mg CaCO 3 / L, the first step, every 667m 3 Add 10kg sodium bicarbonate and 10kg dolomite powder to the water body to increase the alkalinity to 100-110mg CaCO 3 / L, the second step, application: continuously apply the mixture of ochre powder and vitamin C for 7 days, wherein the amount of ochre powder is 12kg / 667m 3 , the dosage of vitamin C is 0.4kg / 667m 3 , Sprinkle once a day, and sprinkle the whole pond; the third step is to increase oxygen, and turn on the aerator throughout the day during the treatment; the fourth step is to feed, and to feed normally according to the feeding situation of the prawns during the treatment.

Embodiment 3

[0013] Embodiment 3, use commercially available total alkalinity detection kit, measure the total alkalinity of prawn breeding disease pond to be 70mg CaCO2 3 / L, the first step, every 667m 3 Add 30kg sodium bicarbonate and 30kg dolomite powder to the water body to increase the alkalinity to 100-110mg CaCO 3 / L, the second step, application: continuous application of the mixture of ochre powder and vitamin C for 6 days, wherein the amount of ochre powder is 10kg / 667m 3 , the amount of vitamin C is 0.3kg / 667m 3 , Sprinkle once a day, and sprinkle the whole pond; the third step is to increase oxygen, and turn on the aerator throughout the day during the treatment; the fourth step is to feed, and to feed normally according to the feeding situation of the prawns during the treatment.

Abstract

The invention relates to a prawn Early Mortality Syndrome (EMS) treatment method, and relates to the prawn culture technical field; the method comprises the following steps: 1, adjusting pond total alkalinity, firstly measuring the culture pond total alkalinity, if the pond total alkalinity is lower than 100mg CaCo3 / L, a sodium bicarbonate and dolomite dust mixture is inputted so as to adjust the alkalinity up to 100mg CaCO3 / L; 2, applying drugs: contentiously using an ochre powder and vitamin C mixture for 5-8 days, wherein the ochre powder dosage is 10-12kg / 667 cubic meter water body, the vitamin amount is 0.2-0.4 kg / 667 cubic meter water body, and spraying the drugs every day; 3, oxygenation, opening an aerator all day in an treatment process, and on other microbe preparation and base changing and water changing drugs are used; 4, feeding, normally feeding the prawns in treatment according to the prawn feeding conditions. The benefit effects are that the method can inhibit prawn diseases, so basically no dead prawn can be found; certain infected prawns can survive for more than 30-40 days until being delivered to the market.

Description

technical field [0001] The invention belongs to the technical field of prawn cultivation, and in particular relates to a method for treating prawn stealing disease. Background technique [0002] The phenomenon of "stealing dead" prawns mainly occurs in high-density cultured shrimp ponds. Because diseased prawns rarely swim to the water surface or shallow water areas, most of the dead prawns appear at the bottom of the pond, which is difficult to detect in time, so it is called "death" by farmers. "Stealing death disease". Academically, EMS is called "Early Death Syndrome" or "Acute Hepatopancreas Necrosis". The texture is soft, the color is light white or light yellow, and the stomach and jejunum are empty. The disease mostly occurs in higher water temperature, above 28°C, after 30 to 60 days of cultivation, the cumulative mortality rate is about 60% to 80%. At present, the stealing phenomenon of prawns in the main prawn farming areas in my country is still very serious, ...
