Problems solved by technology

[0003] One is diseases: especially viral epidemics, which seriously plague the survival and development of my country's shrimp farming industry
[0004] The second is the environment: mainly industrial wastewater and domestic sewage lead to water quality deterioration, which directly threatens the survival and development of the mariculture industry
[0005] The third is bait: Misuse and abuse of various antibiotics and disinfectants in shrimp farming, plus the quality of bait is not high, and its stability in water is poor, resulting in a lot of residual bait and causing organic pollution to the water quality of aquaculture

Embodiment 1

[0019] 1) Pond disinfection treatment: Dilute the gluten ester with water at a ratio of 0.2mg / L, sprinkle the whole pond, remove the beetles and parasites in the pond after 3 hours, and just cover the bottom of the pond with water, Add quicklime, let the pond be exposed to the sun for a week, then sprinkle tea seed cakes, and use Yikanglu disinfectant to disinfect again after three days;

[0020] 2) Cultivation of natural bait: inject water into the pond, let the water depth reach 120cm, mix the fertilizer obtained after 12 hours of fermentation with 2 weight components of Biological Cultured Water King, 0.5 ATP bacteria, and 5 water, according to the interval Add fertilizer once a day, and put fertilizer twice in a row to cultivate water color;

[0021] 3) Mixed breeding: After the water color of the pond is cultivated, prawns are put into the pond according to the breeding density of 80,000 tails / mu, and 300,000 tails / mu of black sea bream and prawns are put into the mixed c...

Embodiment 2

[0026] 1) Pond disinfection treatment: Dilute gluten ester with water at a ratio of 0.4mg / L, sprinkle the whole pond, remove beetles and parasites in the pond after 4 hours, and fill the bottom of the pond with water, Add quicklime, let the pond be exposed to the sun for a week, then sprinkle tea seed cakes, and use Yikanglu disinfectant to disinfect again after three days;

[0027]2) Cultivation of natural bait: inject water into the pond, let the water depth reach 150cm, mix the fertilizer obtained after 15 hours of fermentation with the weight component of 3 bio-cultured water masters, 0.5 ATP bacteria, and 8 water, according to the interval Add fertilizer once a day, and put fertilizer twice in a row to cultivate water color;

[0028] 3) Mixed breeding: After the water color of the pond is cultivated, prawns are put into the pond at a breeding density of 100,000 / mu. After 15 days, 300,000 / mu black sea bream and prawns are put into mixed culture. Certain aggressiveness, mi...

Abstract

The invention discloses a method for preventing and curing prawn virus damage and improving prawn farming yield. The method is characterized by comprising the steps of pond disinfection treatment, natural bait cultivation, mixed cultivation, fertilization and pond water quality management. According to the method, dissolved oxygen is improved ceaselessly and substantially, hazardous substances like ammonia nitrogen, hydrogen sulfide and nitrite in water can be effectively degraded, microorganism ATP bacteria can maintain pond ecological environment, and it can be guaranteed that farming water quality is friendly to environment; immunoglobulin of yolk is fed reasonably to stimulate prawn organisms repeatedly, and the anti-virus and antibacterial ability of hepatopancreas can be improved; thus, the anti-virus and antibacterial ability of the whole organisms can be greatly improved, the development of aquaculture can be promoted, farmers can be driven to get rich, and rural ecological environment can be improved.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for preventing and controlling prawn virus damage and increasing the output of prawn farming. Background technique [0002] Shrimp farming is the pillar industry of marine aquaculture in my country. Since a large-scale outbreak of epidemics occurred in my country's farming shrimp due to white spot syndrome virus (WSSV) in 1993, the shrimp farming industry has suffered a devastating blow. The same situation is almost the same. At the same time, it appears in other shrimp farming countries and regions, and the decline of the shrimp farming industry will directly affect the economic development. Domestically, new ways, new technologies and new models have been provided to curb the occurrence and prevalence of shrimp diseases, but the following problems still exist: [0003] One is diseases: especially viral epidemics, which seriously plague the survival and development of my coun...
