Embodiment 1

[0025] From March 11 to July 1, 2013, it was carried out in a farm in Zhoushan City, Zhejiang Province. Five breeding ponds were selected, each with an area of ​​2 mu and an average water depth of 2m. The pool numbers were 1, 2, 3, No. 4, 5. Each culture pond is covered with plastic film. After the previous breeding cycle, the pond was rinsed with a high-pressure water gun, and the pond was dried for 1 week. The disinfection tank uses 80-mesh sieve silk to filter the natural sea water and water, and the whole pool is sprinkled with bleaching powder to a final concentration of 40-50ppm. After 2 days of sedimentation and aeration, it is extracted to each breeding pool. The water level is 1m. After standing for 3 days, each pool Sprinkle 1000g of Bacillus preparation activated with brown sugar, and 6000mL of EM bacteria cultured by seawater fermentation (calculated on the basis of 2 mu for each pond, without special instructions, the same below). Three days later, seedlings wer...

Embodiment 2

[0033] From August to November 2013, it was carried out in a farm in Zhoushan City, Zhejiang Province. Five greenhouse breeding ponds were selected, each with an area of ​​2 mu and an average water depth of 2m. The pond numbers were numbered 1, 2, 3, 4, and 5. After the previous breeding cycle, the pond was rinsed with a high-pressure water gun, and the pond was dried for 1 week. The disinfection pool uses 80-mesh sieve silk to filter the natural sea water and water, and the whole pool is sprinkled with bleaching powder to a final concentration of 40-50ppm. After 2 days of sedimentation and aeration, it is extracted to each breeding pool. The water level is 0.8m. After standing for 3 days, each Splash 1000g of bacillus preparation activated with brown sugar in the pool, and 5000mL of EM bacteria cultured by seawater fermentation. Three days later, the seedlings were put out on August 1, and the water temperature for the seedlings was 32°C. The vannamei seedlings are the first-...

Abstract

The invention provides a disease comprehensive prevention and control method for greenhouse-cultured penaeus vannamei. The disease comprehensive prevention and control method for the greenhouse-cultured penaeus vannamei is characterized by comprising the following steps: 1, water body regulation and control: (1), matching one culture pond with one disinfection tank, and disinfecting culture water by a bleaching powder, wherein the disinfected culture water can be used after three days; (2), properly irrigating the culture water to the culture pond before putting young shrimps, splashing bacillus preparations and effective microorganisms (EMs) over the whole culture pond, and putting the young shrimps into the culture pond after three days, wherein the bacillus preparations are activated by brown sugar, and the EMs are subjected to fermentation culture by utilizing aerated water of the disinfection tank; (3), no needing of discharging wastewater within 20-40 days before culturing, only adding water once at every three days, and adding the bacillus preparations and the seawater-cultured EMs at every six days; (4) starting discharging a small amount of wastewater once at the morning and the afternoon of every day after culturing for 20-40 days, changing the water once at every three days, and the like; 2, feed management: (1), ensuring the fact that the feeding frequency is different according to different culture time; (2), adding shrimp and crab nutrients, immune polysaccharides and rice vinegar to the fed feed after culturing for 30 days; (3), controlling the feeding amount after the total feeding amount per mu at every day is stable; 3, emergency processing and the like. According to the disease comprehensive prevention and control method for the greenhouse-cultured penaeus vannamei, the explosion of shrimp diseases can be prevented, and the survival rate and the growth rate of penaeus in the culture procedure can also be remarkably increased.

Description

technical field [0001] The invention belongs to the field of aquatic pond culture, and specifically designs a method for comprehensive disease prevention and control of greenhouse cultured prawns. Background technique [0002] Penaeus vannamei is an important marine and freshwater aquaculture species in my country. It has formed an industry with an output value of tens of billions, and has made great contributions to economic growth and fishermen's conversion of production and income. However, similar to other aquaculture species in my country, the excessive investment and blind expansion of Penaeus vannamei aquaculture products have shown great negative effects in recent years. The main manifestations are: 1. The water quality of aquaculture water and pathogenic organisms exceed the standard; 2. The outbreak of diseases represented by the early stealing syndrome of Penaeus vannamei is increasing; 3. Excessive bait feeding and excessive water exchange cause excessive dischar...
