What aspects should be paid attention to in fish farming? In order to ensure a hygienic breeding env

1 Disinfection of ponds. After dredging in the dry pond of the fish pond, 100 kg of quicklime slurry per 667 square meters can be splashed on the whole pond to clean the pond and expose it to the sun to completely remove all harmful substances and kill germs.

2 Disinfection of fish carcasses. Insist on soaking and disinfecting the stocked fish fry, fingerlings and fry and fingerlings in the pond, generally soaking in 3% 5% salt water for about 10 minutes or soaking with one of 10ppm bleach solution, 8ppm copper sulfate solution and 20ppm potassium permanganate solution for 20 minutes.

3. Disinfection of bait, fertilizer and food floors. Insist on disinfection of feed, fertilizer and food farms.

Disinfection of bait. It is strictly forbidden to use expired, rotten, spoiled or bacterial, unclean bait. Animal bait, such as snails, can be washed with water, and fresh ones can be selected for direct feeding; Plant-based bait, such as aquatic plants, is soaked in a 6ppm bleach solution for 2030 minutes before feeding, while terrestrial plants do not need to be sterilized.

Manure should be fermented and disinfected. Fertilizer, such as manure, add 120 grams of bleaching powder to 500 kg of manure, stir evenly and feed. However, in the hot season, manure should be avoided or used sparingly.

The food farm is a place where fish eat, and it should be regularly disinfected to prevent fish diseases during the epidemic season.

4. Disinfection of fish farming utensils. Fish farming utensils that are often used can be soaked in water for half an hour after each use, or they can be placed in the sun and disinfected by ultraviolet light.

Then there is that you have not disinfected the fish tank and fish should pay attention to: the water quality should be fine, the temperature and light should be appropriate, if you can ensure that you are not exposed to direct sunlight and can ensure enough light every day, you can not use it (recommended).

1) Choose the right disinfectant.

The ideal disinfectant should have the following characteristics:

It has a strong disinfection ability.

The disinfectant selected should have strong bactericidal and virucidal capabilities, and be able to kill invading pathogens in a short time.

It has a broad-spectrum sterilization ability.

Broad-spectrum disinfectants have a control and killing effect on a variety of pathogens, which can control the occurrence of a variety of epidemic diseases on the one hand, and save manpower and material resources on the other hand.

It will not damage the items to be sterilized, and will not remain in the livestock and poultry and their products.

**Inexpensive and easy to use.

Economic efficiency is the most important concern of the farm, and disinfectants are one of the fixed expenses of each farm, so the selected disinfectants should be cheap and easy to obtain.

It is relatively stable in the disinfection environment and is not easy to lose its effect.

It is also necessary to select according to the epidemic characteristics of the epidemic, the breed of livestock and poultry, and the age of the day.

When choosing, check the active ingredient, because some disinfectants have different brand names, but the active ingredient is the same.

Commonly used disinfectants include sodium hydroxide, iodophor, potassium permanganate, formaldehyde, peracetic acid, sodium hypochlorite, bleaching powder, lime milk, phenol, Edivo, Xinjieer, Lysur, etc.

2) Prepare disinfectants as required.

Special attention should be paid to the compatibility of disinfectants, and bleaching powder should not be compatible with boric acid and hydrochloric acid; Xinjieerfen cannot be compatible with iodine, potassium iodide, peroxide, etc.; The preparation of disinfectants should be made of deep well water or tap water with less impurities; The stability of general disinfectants will deteriorate after dilution with water, so they should be used and dispensed now; The higher the concentration, the better, and the correct preparation should be made according to the instructions for different sterilization spectrums.

3) Pay attention to the following:

Disinfectants should be stored in a cool, dry and dark environment, otherwise it will cause moisture absorption, decomposition and failure of disinfectants.

Farms should have several disinfectants on hand and use them regularly to avoid resistance.

When purchasing and using disinfectants, pay attention to the production date and shelf life on the outer packaging, which must be used within the expiration date.

Disinfectants cannot be mixed at will to prevent the reaction of the two components of the two components of the phase, weakening or even canceling the disinfection effect.

Clean up the environment or items that need to be disinfected, remove dust and coverings, and help the disinfectant to work.

The disinfectant in the disinfection tank should be changed regularly to ensure an effective disinfection effect.

Do not spray disinfectant on the 1st and day before and after immunization, and do not drink water containing disinfectant on 2 or 3 days before and after and on the day, otherwise, it will affect the effect of immunization.

Select and replace the best new disinfection products in time to achieve the best disinfection effect.

The correct method of disinfection of the farm should be to clean the farm.

The best disinfection method of the farm is the overall disinfection of the system, we have installed a DCW hypochlorous acid generator, using this equipment electrolytic salt and water to generate a high-concentration hypochlorous acid solution for livestock drinking water disinfection, breeding shed disinfection, space environment disinfection, and disinfection of personnel and vehicles, hypochlorous acid oxidation is good, can quickly and broad-spectrum kill all kinds of bacteria, viruses, fungi and other microorganisms, only a full range of sanitize work, in order to effectively prevent the outbreak of the epidemic. Hypochlorous acid produced by the electrolysis of salt and water is non-toxic and harmless to humans and animals.

Environmental sanitation and control of <> farms is a very important part of the aquaculture industry, among which disinfection is one of the important measures to prevent and control diseases and protect animal health. There are several ways to disinfect:

1.Physical disinfection: Physical disinfection is to kill pathogenic Tanze body by physical means such as temperature, pressure, and radiation.

Such as high temperature disinfection, ultraviolet disinfection, steam disinfection, etc. The physical disinfection method is simple to operate and does not produce harmful substances, but it requires disinfection equipment, and the disinfection effect is also affected by environmental factors.

2.Chemical disinfection: Chemical disinfection is the use of chemical agents to kill pathogens.

Such as chloride, hydrogen peroxide, formaldehyde, acetaldehyde, etc. The chemical disinfection method is simple to operate and has a good disinfection effect, but it is necessary to pay attention to the selection and concentration of the agent, as well as the impact of the residue of the agent on the animal.

3.Biological disinfection: Biological disinfection is disinfection by using the inhibition or killing effect of certain microorganisms on pathogens.

Such as the use of probiotics, lactic acid bacteria, etc. Biological disinfection methods are environmentally friendly and do not produce harmful substances, but it is necessary to pay attention to the selection and cultivation conditions of microorganisms, as well as their adaptability to the environment.

4.Gaseous disinfection: Gaseous disinfection is achieved by making the disinfectant into a gaseous state and diffusing it in the air.

Such as ozone disinfection, chlorine dioxide disinfection, chlorine disinfection, etc. The gaseous disinfection method is simple to operate and has a good disinfection effect, but it is necessary to pay attention to the concentration of disinfectant and the ventilation of the use environment.

In general, the choice of disinfection method needs to be considered on a case-by-case basis, including the object of disinfection, the nature of the disinfectant and the conditions of use. At the same time, it is necessary to pay attention to the selection and concentration of disinfectants, as well as measures such as cleaning and ventilation after disinfection to ensure the disinfection effect and environmental safety.

There are 3 types of disinfection methods commonly used:

1) Physical disinfection.

It refers to the method of killing or eliminating pathogenic microorganisms and other harmful microorganisms with physical factors. It is characterized by rapid action, and no harmful substances are left behind in the disinfection items. Commonly used physical disinfection methods include: natural purification, mechanical sterilization, thermal sterilization and ultraviolet radiation.

2) Chemical disinfection.

It refers to the method of disinfection with chemicals. Chemical disinfection method is easy to use and does not require complex equipment, but some disinfectants have certain toxicity and corrosiveness, in order to ensure the disinfection effect and reduce toxicity, the required conditions and instructions for use must be strictly implemented.

3) Biological disinfection.

It is a method of using certain organisms to destroy disease-causing microorganisms. It is characterized by slow action and limited effect, but the cost is low. It is mostly used for the sanitary treatment of large-scale waste and excrement, and the commonly used methods are biological thermal disinfection technology and biological oxidation disinfection technology.

In the specific operation, the appropriate disinfection method is selected according to the different disinfection environment, disinfection objects, and types of disinfectants in the field to achieve the best effect.

The original method of disinfection in the aquaculture industry is generally to disinfect with lime quicklime.

Water is the carrier on which fish depend, and water can not only raise fish, but also bacteria. Therefore, the correct concept of fish farming is to cultivate beneficial bacteria in water quality at the same time, resist harmful bacteria, and achieve ecological balance. If the fish pond is disinfected, the balance will be upset and will not be beneficial to the survival of the fish.

No, it's a three-point poison, and if the fish tank is handled well, it will be poisoned once a year, and I will eliminate it once in two years.

You don't need to clean it for a month or half a month.

Let's talk about the type of fish

No, you don't! Don't add new fish, filter well!

The development of the aquaculture industry is the main body of rural economic development, and farmers have always attached great importance to the management of aquaculture, and the farm is inseparable from the aquaculture industry, so the management of the farm is the key to ensure the development of the aquaculture industry. Among them, the disinfection management of farms is an important part of disease prevention, and the disinfection management measures of safe farms can significantly reduce the incidence of farms, which is of great significance for the development of the aquaculture industry. Let's take a look at some of the commonly used disinfection methods in farms.

%-30% plant ash

Take 10-15 kg of sieved plant ash, add 35-40 kg of water, stir evenly, continue to boil for 1 hour, and replenish the evaporated water. It is mainly used for disinfection of enclosures, sports fields, walls and troughs.

2. Lime powder (calcium oxide).

Take 5 kg of quicklime block, add kg of water, and make it into powder. It is mainly used for the disinfection of the ground and sports field in the house, and has the effect of absorbing moisture, which is ineffective for a long time.

3. Bleaching powder (chlorine-containing lime).

Take a kilogram of bleaching powder, add a kilogram of water, and stir well, that is, 5%-20% bleaching powder suspension. It is used for the disinfection of pens, feeding troughs and excrement. It is easy to decompose with moisture and should be used now.

%-20% lime milk (calcium hydroxide).

Take 5 kg of quicklime and add 5 kg of water, wait for it to be turned into paste, and then add 40-45 kg of water. It is used for the disinfection of enclosures and venues, ready to use, and stirred evenly.

%-75% alcohol (ethanol).

Take 1000 ml of 95% concentration alcohol and add 295-391 ml of water to form 75%-70% concentration of alcohol, which is used for disinfection, needles, thermometers, etc.

% to Suer

Take a kilogram of Suer liquid and add a kilogram of water, mix well. It is used for disinfection of enclosures, utensils and venues, but it is not effective against tuberculosis bacteria.

% caustic soda (sodium hydroxide).

Take 1 kg of caustic soda, add 49 kg of water, and fully dissolve it to become 2% caustic soda water. If a little salt is added, it can enhance the bactericidal power. It is often used for the disinfection of viral diseases, such as swine fever, foot-and-mouth disease and the disinfection of the environment and utensils when the bacteria are infected.

The above is an introduction to some commonly used disinfection methods in farms, I hope it will be helpful to you. In addition, it should be noted that in the process of disinfection, we must pay attention to the correct dosage and method, so as to maximize disinfection.
