What are the commonly used medicines for fish farming? What are the common fishery medicines in aqua

I only use nitrifying bacteria liquid and large particles of sea salt to raise fish, and I basically don't need anything else.

Furacillin (yellow powder) or potassium permanganate, the latter is too potent to be recommended, yellow powder can ** most fish diseases.

Common fish drugs in aquaculture include norfloxacin, ofloxacin, naphridic acid, pyridonic acid, oxaquinic acid, etc. This kind of drug has a good antibacterial effect, a wide range of antibacterial, and strong bactericidal ability.

The more common fishery medicines are, disinfectants, environmental improvers, parasite repellents, Chinese herbal medicines, antimicrobial agents, and biological products.

Regular sprinkling of quicklime into the aquaculture water can not only reduce the occurrence of a variety of diseases, but also provide calcium necessary for aquaculture organisms, which is particularly important for crustacean aquaculture.

It is best not to use medicine, there used to be a mess of fish pond net may not be easy to find now, generally with herbicides mixed with sand medicine, two hours effective, but the fish is slightly toxic. It is recommended not to use the best.

Putting medicine in the ruthless is a herbicide, and the dose is enough, and basically all of them are up, or the clan uses pesticides, but this is inedible.

Good don't use medicine, there used to be a fish pond net may not be easy to find now, generally with herbicides mixed with sand medicine, two hours effective, but the fish is slightly toxic. It is recommended not to use the best.

Mild (external) drugs such as canon, salt, formaldehyde, etc., have an effect on general prevention, and regular prevention is recommended.

Mild (internal) drugs include norfloxacin, allicin, oxytetracycline and some other tetracycline drugs, which have good effects and will have an effect on general fish diseases.

Strong (external) drugs include malachite green (available for ornamental fish, which reacts with water to produce a large amount of zinc, which is prone to zinc poisoning), chlorine preparations, etc.

Strong (internal) drugs include sulfonamides (which act quickly but are prone to drug resistance), furans, and quinolones (which maintain the effective blood concentration in the fish for a time field).

That's pretty much what we use on a regular basis.

Sedan. Lavender medicine. The drugs used to protect the grain reserve warehouse can be bought in many places, and the fish that comes out of the medicine are not poisonous when eaten***.

This season is late autumn and early winter, and the weather is cold, so use fishy bait.

Hang earthworms or bloodworms.

First of all, I don't understand whether you steal fish or raise it home-raised to use medicine, if you raise it yourself, you don't need to use medicine, few people will buy it, you can use a net to catch it, or drain the water and catch it.

If it's stealing fish, don't do it, you can't do such a bad thing.

The essential drugs for raising koi fish are potassium permanganate, chlorine dioxide deficiency, oxymycosis flush soy, red potion, iodophor, gentamicin and malachite green. Among them, potassium permenganate is the most widely used drug, which can purify water quality and deodorize fish tanks. It is often used for sterilization and disinfection.

In order to make the fish immortal, fish farmers will put fish medicine in: yellow powder, methyl blue, and salt.

nitrofuracillin (yellow powder), bright yellow crystalline powder; Odorless, the taste is light, the aftertaste is bitter, the color gradually changes to dark yellow under the sun, very slightly soluble in water, slightly soluble in ethanol, dissolved in alkaline solution, the color gradually changes to dark brown, the pH of saturated aqueous solution is, can quickly interfere with the sugar metabolism process of bacteria and oxidase system and play an antibacterial or bactericidal role.

Methyl blue, also known as oil blue, cotton blue, solvent blue 8b, acid blue 93, royal blue, is an aromatic heterocyclic compound, which is used as a biological staining agent for the staining of protozoan living organisms, bacteria and nerve cells in animal histology, soluble in water and insoluble in ethanol.

The large salt is the salt in chemistry, which can be divided into single salt and combined salt, single salt is divided into normal salt, acid salt, basic salt, combined salt is divided into double salt and complex salt, in the salt generated by complete neutralization of acid and alkali, there will be no hydrogen ions in the acid, there will be no hydroxide ions in the base, only metal cations and acid ions, and the neutral salt is the normal salt.

1. Potassium permanganate (potassium permanganate is good at the skin) purple-black prismatic crystal. Antiseptic disinfectant for external use. Gill rot has some effect. It is also a good medicine for the disinfection of bait, tools and fish tanks.

2. Chlorine dioxide spectrum, efficient and fast-acting oxidative sterilization disinfectant. At the same time, sterilization has the effect of disinfecting water bodies and improving water quality.

3. Bromochlorohydantoin.

It is an ideal disinfectant with high efficiency, broad spectrum, fast, safe, non-toxic and no residue, which can be used for the daily disinfection of aquaculture water, with good efficacy and will not damage water quality, and can effectively treat almost all bacterial and viral fish diseases.

4. Povidone-iodine (iodophor).

Trauma disinfectant. Apply directly to disinfect. It has a good curative effect on viral, bacterial and fungal skin surface fish diseases such as skin surface hemorrhage, body surface ulceration, boils, rotten skin and rotten flesh, printing disease, acne, local erection scale disease and water mold disease. In addition to the disinfectant effect, it also has the effect of promoting the healing of damaged **.

Here's how to use powdery fish:

1. Isolate the medicated bath and pure: isolate the sick fish in a separate container, use the trapped water at the same temperature, fully stir the yellow powder until the water is completely dissolved and then put the sick fish in, the amount of yellow powder is usually 100 liters of water with 1 gram, and the time of each medicated bath is about 20 minutes, during which attention should be paid to oxygenation.

2. The whole tank of medicinal bath: yellow powder is directly poured into the fish wheel simple tank to cure the disease, provided that the fish tank is full of diseased fish, and you use very little, otherwise it is not recommended to do this, it will only harm your fish.

Precautions for using yellow powder

1. While using yellow powder medicated bath, it is necessary to ensure the amount of dissolved oxygen in the water, and it is best to assist in oxygenation.

2. During the use of yellow powdery powder to treat diseases, you should stop eating, and you can't supplement nutrition at the same time as we humans treat diseases, so don't feed the yellow powder medicated bath.

3. Pay attention to shading when powdery fish is sick to ensure a quiet environment.

4. It is best to take a yellow powder medicated bath above 20 degrees Celsius to keep the water temperature constant, so that the medicinal effect is better.

5. There is no problem with the use of yellow powder in weakly acidic and weakly alkaline water, but do not mix it with alkaline drugs, so as not to affect the efficacy of the drug.
