Embodiment 1

[0049] A method for biologically regulating and cultivating large-scale prawns, comprising the following steps:

[0050] Step 1. Establish a standard high-level breeding pond:

[0051] 1) Set the central sewage outlet of the high-level culture pool to be 1.5m higher than the sewage outlet, and set the sewage outlet above the high tide level of the spring tide, raise water for culture, and increase oxygen at the same time on the surface and bottom of the high-level culture pool, and set the area of ​​the high-level culture pool to be 2 ~4 mu, water depth is 1.7~1.8m;

[0052]2) Use dibromohydantoin solution with a concentration of 200ppm and bleach solution with a concentration of 250ppm to disinfect the high-level culture ponds respectively.

[0053] Step 2. Comprehensive treatment of water source water quality:

[0054] 1) The seawater is pumped to the special reservoir after being filtered through the coarse sand, fine sand, activated carbon and screen of the sea water sou...

Embodiment 2

[0091] Embodiment 2: Take the No. 10 high-level culture pond as an example.

[0092] 1. On March 15, 2012, No. 10 high-level culture ponds were selected, and 2 kilograms of dibromohydantoin (concentration was 200 ppm) and 5 kilograms of bleaching powder were dissolved in water (concentration was 250 ppm) to disinfect the high-level culture ponds respectively. And clean it for later use.

[0093] 2. On March 16, 2012, the seawater was filtered through the coarse sand, fine sand, activated carbon, and screen of the sea water source filtration device in sequence, and then pumped to the special reservoir, and then added with strong chlorine essence 40ppm for disinfection for 12 hours to kill free viruses and The host organism of the virus, Vibrio; then treated with sodium thiosulfate 4ppm, fluorspar powder 20ppm and high-speed flowing water for 3 hours to neutralize the disinfection residues of chemicals, heavy metals and solid organic matter; after 24 hours of precipitation, pu...

Embodiment 3

[0116] Example 3: Take the No. 8 high-level breeding pond as an example.

[0117] 1. On August 10, 2012, No. 8 high-level culture ponds were selected, and 2 kilograms of dibromohydantoin (concentration was 200 ppm) and 5 kilograms of bleaching powder were dissolved in water (concentration was 250 ppm) to disinfect the high-level culture ponds respectively. And clean it for later use.

[0118] 2. On August 11, 2012, the seawater was filtered through the coarse sand, fine sand, activated carbon, and screen of the sea water source filtration device in sequence, and then pumped into a special storage tank, and then 40ppm of strong chlorine was added for disinfection for 12 hours to kill free viruses and The host organism of the virus, Vibrio; then treated with sodium thiosulfate 4ppm, fluorspar powder 20ppm and high-speed flowing water for 3 hours to neutralize the disinfection residues of chemicals, heavy metals and solid organic matter; after 24 hours of precipitation, pump to...

Abstract

The invention relates to the technical field of prawn culture, in particular to a biological regulation culture method for large prawns. The method includes: building a standard high-place culture pond, comprehensive treatment of water source quality, culturing basic baits, putting in prawns, biological regulation of water quality and diseases of the high-place culture pond and the like. The method has the advantages that an efficiency and environment-friendly large prawn culture mode is provided, biological regulation using beneficial bacterium and algae is adopted, the prawns cultured by the method are large, high in quality and yield and good in culture effect, the problem of residual chemicals is eliminated, a novel development approach is provided for prawn culture industry, and the method is promising in market prospect.

Description

technical field [0001] The invention relates to the technical field of prawn cultivation, in particular to a method for biological regulation and cultivation of large-scale prawns. Background technique [0002] At present, there are three main modes of shrimp farming in my country, namely, high-density intensive culture in high-level ponds, intensive or semi-intensive extensive culture in low-density earthen ponds, and low-density extensive culture in dams. The first type of high-density intensive culture in high-level ponds (more than 100,000 seedlings per mu), which adopts high-level water extraction, central control of sewage discharge, separation of drainage and irrigation, and simultaneous oxygenation of the surface and bottom. Water purifiers and ecological preparations regulate water quality, and antibiotics are used to prevent and control diseases, which will lead to drug residues, which will pollute the environment and make it difficult to guarantee the quality and ...
