1. Water disinfection, insecticide, cleaning:
Benzalkonium bromide: stripping and cleaning gills - disinfecting and killing insects - improving water permeability;
(1) First use 45% times of benzalkonium bromide solution 60 ml / mu / 1 meter deep, use once every 2 days, continuous use 3 to 5 times; dilute 300 to 500 times and then evenly sprinkle;
Note: Benzalkonium bromide is a surfactant disinfectant, which improves water permeability and can peel off dirt adhering to the parotid gland, and plays a role in disinfecting and killing ciliate nematodes;
2. If the PH value is high (for example, when Ph is higher than 8.2):
Reduce the PH value with "fermented corn liquid", compress ammonia nitrogen, while desulfurizing hydrogen and inhibit Vibrio, four-in-one operation;
Methods: "Fermented corn liquid" 25~50 kg/mu + "strong microbial desulfurizer" 100~200 g/mu; principle: carbon source + lactic acid bacteria + sulfide hydroxide bacteria + absorption of assimilated ammonia nitrogen;
3. If the PH value is low, for example, when the PH is lower than 7.2):
Carry out pH value appreciation + disinfection + insecticide;
(1) When the PH of the water body is lower than PH7.2, use quicklime powder 10 to 15 kg + povidone iodine 300 ml/mu per mu until the PH rises to 8.0, the quicklime powder is directly sprinkled along the edge of the pond for about 1 meter, and the povidone iodine is diluted 100 times and evenly sprinkled;
Precautions: If the ammonia nitrogen in the water body exceeds the standard, it is not possible to increase the PH value of quicklime, because the toxicity of ammonia nitrogen increases at a high PH value;
4. If the nitrite in the pond exceeds the standard, it is treated with carbon source + denitrifying bacteria;
(1) Use "fermented corn liquid" 10 kg/mu + "strong micro-denitrifying bacteria" 30 g/mu; after mixing and stirring the two, directly sprinkle; use once every 3 days, and use at least 3 times continuously;
Note: If there is no "fermented corn liquid", replace it with 2 kg of brown sugar, and add 30 kg of water to soak for 1 to 6 hours and then sprinkle;
5. If the shrimp have enteritis and white stool at the same time, the silt in the pond is very dirty and smelly, and the vibrio silt exceeds the standard;
(1) Sprinkle 100 g/mu of "arc cleaning mud pellets" every 3 to 5 days, a total of about 2 to 3 times, "arc cleaning mud pellets" can be stored in the silt for 7 days to slowly release the live bacteria in the coating, especially Clostridium butyrate colonization in the silt, thereby controlling the harmful germs in the silt;
(2) Mix in the feed "lactic acid butyric acid mixture treasure" 10 g / kg feed, add a small amount of water to dissolve and sprinkle in the feed feeding, meal mixture, continuous use for about 5 days;
6. If the pond algae is too concentrated, there are even thick green algae, cyanobacteria, naked algae, etc.:
Use: deepening water color to reduce photosynthesis + super large amount to improve the carbon-nitrogen ratio of water bodies + decomposition of concentrated algae; three-in-one treatment;
(1) Sodium humate used during the day 1~3 kg/mu + "fermented corn liquid" 25~50 kg/mu;
(2) Activate "strong microbial cyanobacteria net" 1 pack of 2 mu + brown sugar 2 to 4 kg/ mu + water 50 kg during the day; after soaking and activating for 1 to 12 hours, leave it until the evening to sprinkle;
(3) Freshwater aquaculture can conditionally sprinkle 2 to 4 kg/mu of sea salt to relieve stress.
Notes:
(1) Regardless of the AMOUNT of PH, it is necessary to use "fermented corn liquid", the higher the PH, the greater the amount of "fermented corn liquid", and vice versa, the smaller the amount;
(2) Principle: sodium humate deepens the water color, a large amount of "fermented corn liquid" improves the carbon-nitrogen ratio of the water body, and "strong microbial cyanobacteria net" decomposes the concentrated algae;
7. Operation in emergency state: inhibit vibrio and other harmful bacteria
If the detection of Vibrio in water exceeds the standard, the situation is urgent, you can first use the "seedling rescue lactic acid bacteria phase" 1 pack of 2 acres, add 5 kg of brown sugar, 100 kg of water, soaked within 6 to 12 hours, evenly sprinkled;
Note the problem
1. Do not use zeolite powder to splash the pool water, which will stimulate the gills, aggravate the disease, and even cause a large number of deaths.
2. Farmers with water source conditions can change more water, use more "fermented carbon fertilizer" and strong microbial agents to promote the material circulation of water bodies.
3. During the treatment period, appropriately reduce the amount of feeding.
