Problems solved by technology

[0003] The traditional culture method of Penaeus vannamei is to directly raise shrimp seedlings in a large pond at a water temperature above 20°C. This farming method has poor protection against poisoning, the survival rate of shrimp seedlings is low, and the finished shrimps are small in size and have large individual differences. , resulting in poor economic benefits due to poor quality and low output

Abstract

The invention provides a toxin-proof culture method of penaeus vannamei boone. The toxin-proof culture method comprises: A, removing pond bottom sludge of a culture pond and scattering quick lime; solarizing for 2 to 3 days; B, laying mixed soil, which is obtained by uniformly mixing kaolin and fine aggregate at the mass ratio of 1 to 1, with the thickness of 10cm at the pond bottom of the culture pond, and solarizing for 2 to 3 days; C, injecting water into the culture pond until the water depth is 50cm to 60cm; scattering plant ash, fowl manure and calcium magnesium phosphate fertilizer; after standing for 10 to 15 days, injecting the water into the culture pond until the water depth is 1.5cm to 1.8m; D, putting young shrimps into the culture pond and introducing ozone into the culture pond; E, after the young shrimps are put for 1 to 2 months, spraying a chlorine dioxide water solution into the culture pond every 7 to 10 days to enable the concentration of the chlorine dioxide in the culture pond to be 0.5mg / L to 1.5mg / L; continuously spraying for 3 to 5 times. By adopting the toxin-proof culture method of the penaeus vannamei boone, the incidence rate of diseases in a culture process is effectively reduced and the culture survival rate and the culture quality are improved.

Description

technical field [0001] The invention relates to the technical field of aquatic product cultivation, in particular to a poison-proof cultivation method for Penaeus vannamei. Background technique [0002] China is a big aquaculture country in the world, and its aquaculture volume accounts for more than 65% of the world's total. Seawater and freshwater shrimp farming has been developed in my country for many years, and has considerable economic benefits. Penaeus vannamei is the highest aquaculture output in the world today. One of the three major shrimps, most of the regions in my country have gradually promoted farming. The meat of Penaeus vannamei is delicious, and the processed meat rate can be as high as 67%. It has a wide temperature range and can grow at 18-32 ° C. It also has a wide salt range and can grow at a salinity of 1-40 ‰. It is an excellent desalinated cultured species. Penaeus vannamei grows fast and has strong disease resistance. It has gradually become the m...
