What are the main drugs used in fish pond farming to prevent parasites and diseases?

Pond cleaning and disinfection drugs: This kind of drugs are sprinkled into the bottom of the pond or pool water, which can eliminate the pathogen and cut off its infection or invasion, which is an indispensable drug for the prevention of fish diseases. Commonly used are quicklime, bleaching powder, tea withering, etc., with quicklime having the best medicinal effect.

Ectoparasitic drugs: These drugs can kill ectoparasitic flagellates, ciliates, straw worms and fish eels. It is better to use it to prevent disease before the fish disease epidemic season, when the pathogen begins to multiply and grow.

Commonly used are copper sulfate, ferrous sulfate, iodine, trichlorfon, mercurous nitrate, etc. Among them, the mixture of copper sulfate and ferrous sulfate is one of the commonly used drugs in the prevention and control of fish diseases.

Drugs for the treatment of intestinal diseases: this kind of drugs have the effect of inhibiting and killing the pathogenic bacteria that cause intestinal infection in fish, and can be used internally for bacterial enteritis of green and grass carp, and can also be used as a body surface fungicide to prevent and treat erythroderma, gill rot, etc. Commonly used are sulfathiazole, sulfadia, nitrofuracillin, furazolidone, garlic, etc.

Fingerling soaking drugs: This kind of drugs mostly disinfect the fish body when the fingerlings are transferred to the pond for rearing to prevent the fish from bringing pathogens into the pond where the fish are raised. Commonly used are table salt, malachite green, potassium permanganate, sodium bicarbonate, etc.

Antimicrobial drugs: This type of drug has the best effect on some fish diseases caused by pathogenic bacteria, such as leukoderma and boils. Commonly used are penicillin, erythromycin, chlortetracycline, qingfengmycin, etc.

Commonly used and large quantities of drugs such as quicklime, copper sulfate, etc., can be prepared more, and other drug storage as long as it can ensure the use of 1 2 times in the fish farming area. It is especially reminded that the stored drugs should be placed in a cool and dry place to prevent deliquescent and invalidation of the drugs, and it is best to use glass bottles and write labels to avoid mistakes and affect the use effect.

In the fish pond, the fish body will have a certain number of parasites before wintering, after the breeding and latent breeding of the wintering period, once the pond water temperature rises after the spring of the next year, these parasites are easy to multiply in large quantities, so that the farmed fish are infected with parasitic diseases. Due to the low water temperature of the pond in winter, the use of external insecticides is relatively poor, so it is generally not recommended to kill insects during the wintering period, but it can be used for prevention and internal deworming.

In the process of breeding, pathogens, physique and environment are the three basic factors that constitute the pathogenesis of the body, therefore, for the parasite prevention and control of fish ponds in the wintering period can be worked on these three factors

1. Enhance physical fitness.

Therefore, it is recommended to choose a better quality compound feed to feed it in a timely manner (sunny weather with higher temperature), and cooperate with immunomodulatory products such as liquid peptide mei, etc., to enhance the physical fitness of fish; It should also be mixed with chivalrous liver and gallbladder to prevent the occurrence of hepatobiliary disease. Through these measures, the physique of fish can be improved, the resistance of fish to parasites and other pathogens will be enhanced, and the outbreak of parasitic diseases will be prevented.

2. Improve the water environment.

During the wintering period, it is necessary to do a good job of aeration and bottom modification, stabilize water quality and water temperature, and reasonably control the water level, so as to avoid the fish from having a stress response and causing freezing to death and frostbite due to floating heads. According to the actual situation of the aquaculture pond, targeted measures should be taken to improve the water environment for fish to survive during the wintering period, and reduce the probability of disease infection and parasitic disease outbreaks. Strengthen the patrol of the pond at ordinary times, pay attention to observation, find abnormalities in time and take countermeasures to deal with them, so as to avoid increasing losses.

In recent years, there have been frequent outbreaks and high incidence of fishpond parasitic diseases. Fish parasitic diseases are at their peak in October and are prevalent for a long time and cause serious damage. Several prevention and control methods are introduced.

Symptoms Chinese eel disease: dyspnea, restlessness, increased mucus on the gill and whitish ends of the gill filaments. The female insect of the Chinese eel hooks the gills of the fish with a large hook, and when a large number of parasitism, there are many small white maggots on the upper edge of the gills, so it is also called gill maggot disease.

The Great Chinese eel is parasitic only on grass carp, duke and red-eyed trout, and the silver carp is only parasitic on silver carp.

Diseased fish swirl or swim wildly on the surface of the water, and the tail fin is exposed to the ice, and the body of the diseased fish is emaciated, and its growth is stunted or even killed.

Ring worm disease: the gill filaments of diseased fish are increased, all or part of them are pale, it is difficult to breathe, the gills are significantly floating, and the insect body is not easy to see with the naked eye.

type of movement. The insect body destroys the gill tissue of the fish, causing the fish to die.

Anchorhead eel disease: the worm can parasitize the whole body of the fish, the front half of the worm body burrows into the host tissue, the second half is exposed, when seriously infected, the fish body seems to be dressed in a coat, so it is called "coat disease". Flower silver carp.

When infected with this disease, it causes swelling and inflammation of the tissues, forming pomegranate-like red jue, grass carp, carp, etc.

Prevention and treatment The above three diseases can be prevented and treated by the following methods:

Improve the environment with quicklime after winter harvesting or before the arrival of the spring rainy season.

Disinfection, the dosage of 25 40 grams of cubic meters, at this time the use of less medicine, can save investment.

After disinfection, insecticides are used to kill 90% crystal trichlorfon once.

grams of cubic meters or new insecticides, the dosage is as indicated.

Before putting the fish, disinfect the medicated bath with 20 grams of cubic meters of potassium permanganate.

Soak for 15 to 20 minutes or 500 grams of crystal trichlorfon cubic meters for 15 minutes.

Reasonable stocking density is too large or unreasonable combination will make the fish activity space relatively reduced, and the fish secrete too much adrenaline hormones.

Physical strength decreases, which increases the chances of dyeing and spreading.

Strengthen management to avoid stress reactions.

Improves the fish's own resistance.

Feed 100 grams of trichlorfon into 30 kg of bran or compound feed for 4 days.

Although I am a pharmacist, fish medicine is really deep water, white tablets seem to be metronidazole, yellow powder seems to be nitrofuracillin, most fish drugs such as furazolidone do not write generic names, do not write ingredients, and dare to sell ** if you take a trade name of insecticide**. Because this circle is a person who is stupid and has a lot of money, if you want to say that he is stupid, he will scare you, a poor ghost, and he is also worthy of playing in the water tribe, he can't afford to buy it too expensive, get out.

1. Disinfection of fish fry before entering the pond.

1. Cleaning pond disinfection. It is to be sprinkled in the fish and shrimp breeding pond after dredging and trimming, and then dissolved with quicklime and water. The water in the pool is 6 10 cm deep, 85 110 grams of quicklime per square meter of water surface, 80 400 grams of quicklime per square meter of water surface when the water depth is 1 meter, and the pH value of the pool water is about 11 after 24 hours, which can quickly remove wild trash fish and shrimp, large aquatic organisms, parasites and bacteria.

This disinfection method is more thorough, generally carried out before the fry are planted, focusing on removing pests in the fish pond to avoid the death and damage of the fry.

2. Disinfection of fish fingerlings. Fingerlings should be disinfected before stocking, and the fish body can be soaked in a certain concentration of salt water or medicinal solution to kill the bacteria and parasites parasitic on the fish body, and the specific soaking time depends on the water temperature, drug concentration, and fish physique.

2. Feeding disinfection.

Feeding disinfection is mainly to disinfect the bait and feeding grounds of fish farming. Insist on mixing 1% salt or 100 kg of feed with 250 grams of "fish blood stop" in concentrate feed, once a month, for 4 5 days. During the fish disease season, each food field is disinfected with bleaching powder or quicklime every 10 15 days, and hanging bags can also be disinfected.

3. Regular disinfection.

Regular disinfection is to regularly disinfect the water body of the fish pond. It is important to disinfect water bodies on a regular basis. Especially in the growing season of fish and shrimp, 10 20 grams of quicklime per square meter of water surface per month is added to the whole pool and sprinkled 1 2 times, which can maintain the pool water is weakly alkaline, sufficient dissolved oxygen, and fresh water quality, which is conducive to promoting the growth of fish and shrimp, so that 80 90 flocculent in the water adsorbs and presides, which is conducive to improving the quality of commercial fish and shrimp.

To achieve early prevention of disease, early treatment of disease, prevention is more important than cure.

Potassium permanganate can kill some parasites, but it is not recommended due to the harsh concentration requirements. Generally, there are two types of parasites that harm fish, one is ectoparasites and the other is internal parasites. The former will cause congestion on the surface of the fish's body, which can be removed with tools such as tweezers, and then disinfect and sterilize the wound.

The latter will cause the fish to be emaciated and weak, requiring the use of drugs such as large white tablets**.

1. Cryptowhipworm: Cryptowhipworm is generally parasitic on the gills of fish, and the parasitic fish often have black bodies, and at the same time, the gill filaments are bright red, and there is gray-white mucus on them. For this parasite, it needs to be soaked with a mixture of copper sulfate and ferrous sulfate, usually for about 10-30 minutes.

2. Wheel worm: Wheel worm will attack the body surface and gills of the fish and absorb nutrients from it, resulting in the fish being thin and weak, and they will also move out of the group and move very slowly. When the infection is found, the fish need to be soaked in 2% salt water, which usually takes about 5-10 minutes.

3. Small melon worm: Small melon worm is a common parasite that harms fish, which can cause fish to suffer from white spot disease. When the disease occurs, white pustules appear on the surface of the fish, which can prevent them from foraging.

It is also very simple to want **, as long as the water temperature is slowly increased, if it exceeds 25, you can limit the growth and reproduction of parasites, and if it exceeds 28, you can eliminate it.

Summary. Adding 1 2 grams of the odorless anthelmintic albendazole tablets per 100 kg of feed can effectively repel the internal parasites of the eel. Feed twice a day at a fixed point, and the daily feeding is 5%-8% of the eel's body weight.

If the amount of medicine is added, 150 grams of the drug and 30 grams of the drug binder can be mixed evenly in a dry state....Adding 1 2 grams of the odorless anthelmintic albendazole tablets per 100 kg of feed can effectively repel the internal parasites of the eel.

Summary. Dear, hello, I'm glad to answer for you, the fish pond fish is sick, I don't know what medicine can be used to solve it? A:

First of all, if you have multiple fish in the same tank, immediately isolate the sick fish and put them in a salt bath in 2-3% salt water for half an hour. If there is only one fish in the tank, you can take a salt bath directly in the main tank. Or soak small fish diluted with malachite green; Generally, the color of the water should be changed, not too much, and it is necessary to observe, if the small fish can't stand it, don't take too long.

Once a day for a week. In addition, pay attention to the water quality, if you have the conditions, you should find a professional person to come and see or take it to the fish shop to ask, and if you don't understand, it is better not to use the medicine indiscriminately.

When the fish is sick, everyone recommends using permanganate to search for potassium, although these drugs need to be used with cavity wax, and may only use this kind of medicine, but you must understand their benefits and disadvantages for your fish farming. Another example is nitrofuracillin (yellow powder), which is a broad-spectrum antibacterial drug that can be used both internally and externally, and can be used for many diseases, but it cannot be used in grass tanks, and the harm is to corrode aquatic weeds.

Just follow the above methods.
