Example Embodiment

[0048] Example 1

[0049] A method for biological regulation and breeding of large-scale prawns, which includes the following steps:

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

[0051] 1) The central sewage outlet of the high-level breeding pond is 1.5m higher than the sewage outlet, and the sewage outlet is set above the high tide level of the spring tide. The water is raised and the surface and bottom layers of the high-level breeding pond are simultaneously aerated. The area of ​​the high-level breeding pond is 2 ~4 mu, the water depth is 1.7~1.8m;

[0052] 2) Use a 200ppm dibromohydantoin solution and a 250ppm bleach solution to disinfect the high-level aquaculture ponds.

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

[0054] 1) The sea water is filtered through the coarse sand, fine sand, activated carbon, and screen of the water source filtering device in the sea area and then pumped to the special reservoir;

[0055] 2) Disinfection ...

Example Embodiment

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

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

[0093] 2. On March 16, 2012, the sea water was filtered through the coarse sand, fine sand, activated carbon, and screens of the water source filtering device in the sea area, and then pumped to a special reservoir, and then added strong chlorine 40ppm to disinfect for 12 hours to kill free viruses and Virus host organisms, Vibrio; then treated with sodium thiosulfate 4ppm, fluorspar powder 20ppm and treated with high-speed running water for 3 hours to neutralize chemical drug disinfection residues, heavy metals and solid organic matter, etc.; then settled for 24 hours, and then pumped to high cultivation Pool spare.

Example Embodiment

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

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

[0118] 2. On August 11, 2012, the sea water was filtered through the coarse sand, fine sand, activated carbon, and screens of the water source filtering device in the sea area, and then pumped to a special reservoir, and then added strong chlorine 40ppm to disinfect for 12 hours to kill free viruses and Virus host organisms, Vibrio; then treated with sodium thiosulfate 4ppm, fluorspar powder 20ppm and treated with high-speed running water for 3 hours to neutralize chemical drug disinfection residues, heavy metals and solid organic matter, etc.; then settled for 24 hours, and then pumped to high cultivation Pool spare.

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 ...
