What is the disease of white spots in fish? What to do if there are white spots on the fish?

We have to deal with the white spot disease of this ornamental fish, in fact, prevention is better than cure. Because this white spot disease is like our human cold, most of the cases are caused by excessive temperature changes. Therefore, in this alternating season of winter and spring, the temperature changes greatly, and the water temperature naturally changes greatly.

Therefore, at this time, we must not remove the heating rod in the fish tank in advance, or put the heating rod for a period of time, until the overall temperature on our side is relatively stable, and then remove the heating rod, which will be better.

Another precautionary measure is that when we change the water in the fish tank, try to make the water temperature of the water ready to be changed the same as the water temperature in the original fish tank, that is, it is best to put it in the same space, if there is a fluctuation, it should not exceed three degrees. Otherwise, if the difference in water temperature between the two is too large, and the water is more drastic when changing the water, it is easy to cause the ornamental fish to be washed by the water, due to the instability of the local water temperature in the water, resulting in some ornamental fish with weak physique are susceptible to white spot disease.

Once a certain ornamental fish is found in the fish tank and is infected with white spot disease, it must be quickly isolated. Because this white spot disease is contagious like a cold, and in a confined space in a fish tank, it spreads relatively quickly. Therefore, it is necessary to isolate as soon as possible, and then carry out the corresponding **.

**There are two commonly used methods for white spot disease, one is to use the characteristics of this small melon insect not to withstand high temperatures, and heat the water temperature to 30 degrees, so that these small melon insects will die automatically and fall off automatically. One thing that needs to be reminded here is that sometimes the display thermometer on our heating rod is not accurate, so we need to match another thermometer to measure whether the water temperature is really increased to 30 degrees. Finally, we adjust our heating method through several measurements.

Another ** method of white spot disease is to directly use a medicine called white spot net. Because white spot disease is a common disease in ornamental fish, there are many white spot net drugs on the market, which can generally be cured. However, we should also pay attention to one point when using medicine, if there are some fish without scales in the fish tank, such as scavenger fish, bearded fish, elf fish, mouse fish, these ornamental fish are not resistant to drugs.

So, if these fish are sick, the first way to use them is to raise the temperature to **.

This is the prevention of white spot disease, and there are ** suggestions, I hope it can effectively help everyone to avoid the aquarium fish at home from getting sick. Again, no matter what ornamental fish disease is more prevention than cure, so we must do it in the previous details, so as not to get sick when you get sick and come again, the effect is much worse.

Melon worm disease is a parasite that parasitizes on the surface of the fish's body and looks dotted. It is usually caused by fish trauma or low water temperature and emaciation.

It is white spot disease, which is a common disease of fish and is usually susceptible to disease when the temperature is relatively low. The water quality should be replaced in time and the temperature should be raised appropriately.

There are two types of white spots on a fish:

One is melon worm disease, which is a parasite that parasitizes the surface of the fish's body and looks dotted. It is usually caused by fish trauma or low water temperature and emaciation.

The other is powdering, which is caused by eosinophilic ocudinoflagellates. One of the main reasons is that there is too much green algae in the fish tank, which leads to its outbreak. The other is that the water quality in the fish tank is too poor, resulting in acidic water quality.

I like to raise fish, I raise fish with my heart, and my life is both fulfilling and happy.

There are small melon worms in the water, which is caused by the entry of germs and the low temperature of the water, so it is better to feed pellet feed instead.

Solutions to the problem of white spots and white hairs on the body of fish:

1. Put the fish tank indoors, or heat it properly, slowly, not too suddenly, otherwise the fish will not be able to stand it.

2. Put some mercurous nitrate in the water, which is sold in the fish market, about 2-3 yuan a bottle, and use it according to the instructions on the bottle. At the same time, you can put some yellow powder (fummicillin), the water will be a little yellow, it doesn't matter, use the medicine for three days, and then change one-fifth of the water every day until the water is not yellow. Frammicillin and mercurous nitrate can be mixed, nothing ***.

But please remember: frammicillin and high acid nails must not be mixed, there will be chemical reactions, and the water will be very turbid, so the yellow powder must not be put or brought in in the tank. Flocillin focuses on white disease, mercurous nitrate focuses on white spot disease, and high monocillic acid is used for disinfection.

If you use a high acid nail, you can only fish it out for a single use, and after use, you must use the water scooped out of the tank to pass it first (soak it) before you can fish it back into the original tank. The time of the turtle must be short, not more than two minutes, and the power of the drug is very great.

1) When changing the water, it should be noted that the temperature difference is too large, which will cause the fish body to "catch a cold" and let the pests and diseases take advantage of the weakness to invade the fish body.

2) Make full use of the weakness that the melon worm can die on its own after 24 hours if it cannot find a host, and the water for raising goldfish should be exposed to the sun or left to stand for 2-3 days before use. This is one of the best ways to prevent melonworm disease.

3) according to the proportion of grams of mercury nitrate per cubic meter of water for the whole pool (tank) or when the water temperature is below 15, you can put grams of mercurous nitrate in 50 kg of water, bathe the sick fish for about l hours, and then wash with isothermal new water, and then put back into the sterilized new pool (tank), and rest after adding a little green water. However, it should be noted that mercurous nitrate is highly toxic and should be used with caution. In particular, the resistance of small fish to the liquid medicine is weaker than that of large goldfish, so the concentration of the liquid medicine should be appropriately reduced, and the immersion time should be appropriately shortened.

4) Put 10 kg of red mercury (i.e. medical red syrup) ml, bathe the sick fish for 5-15 minutes. If it is color, it can be directly rubbed with red mercury on the part or around the body. After washing with fresh water, and then put it into clean new water to raise, you can also splash 3-5 (g) ml of red mercury according to l cubic meters of water (i.e. l000 kg) to make the pool (tank) water concentration of 3-5 mg liters.

After 2-3 days, depending on the condition of the condition, you can change to the above bathing method** once, and then change to clean new water (tender green water) to feed, and at the same time extend the sunshine time, appropriately increase the water temperature, stop eating, and increase oxygen, and you can obtain satisfactory results.

5) According to the characteristics of small melon insects that are not resistant to high temperatures, put them in the sun, raise the water temperature to 30 hours, rub red mercury around the body of the fish, and then wash them with new water and then clean them in warm and tender green water to raise, stop eating, and change to new water after 1 week in the sun.

6) In the range of water temperature 20-26, each cubic meter of water (1000 kg) baths the diseased fish with grams or grams of malachite green solution for 2 hours, which can kill small melon worms and is relatively safe for goldfish.

1. The causative agent of fish white spot disease

Fish white spot disease is a common aquatic animal disease caused by a protozoan called white spot monas. This single-celled organism is ubiquitous in water and can enter the interior of the fish through different pathways, causing diseases.

Leukomonas is highly infectious, usually in large numbers in water, and is prone to infect fish, resulting in the occurrence of fish white spot disease. In addition, low immunity and poor water quality in fish are also important factors that cause white spot disease in fish.

2. Feeding management is not the source of holes

The occurrence of fish white spot disease is closely related to the feeding and management of fish. If the fish feed is not nutritious or contains harmful substances, the immunity of the fish will be reduced and it will be susceptible to pathogen infection. In addition, poor water quality is also an important cause of fish white spot disease, too high or too low water temperature and overly clean water quality will destroy the ecological balance of the water body, and then cause diseases.

3. Lack of knowledge of fish disease prevention

Lack of knowledge about fish disease prevention is also one of the reasons for the occurrence of fish white spot disease. Some fish breeders lack scientific understanding of the feeding environment and feed, and only pursue the number and speed of fish reproduction, while ignoring the health problems of fish. Once a fish disease occurs, due to the lack of relevant ** and prevention knowledge, it is often misdiagnosed and mistreated, delaying the disease, and eventually leading to a large number of fish deaths.

4. Improvement of pathogen resistance

With the epidemic of fish white spot disease and the gradual increase of drug-resistant strains in fish, the generation of anti-drug has gradually become one of the important causes of fish white spot disease. In order to increase the disease resistance of fish, some fish manufacturers will use a large number of antibiotic drugs in the process of feeding, which will not only make fish dependent on drugs, but also reduce the immunity of fish body, and then become an important target of pathogens.

White spots on the fish are melon worm disease.

White spot disease is caused by a parasite called melon worm. The cause of this disease is mainly caused by the large temperature difference, and there will be a small number of sporadic white spots on the body of the diseased fish at the beginning, which generally do not break out in pieces, and the white spots are larger than those of powdering. The most important point is that the end of the fin of the diseased fish does not show redness and ulceration, and only in the later stage when it is severe will a large number of white spots erupt.

Melon insects are afraid of high temperatures, so heating up** is the best and easiest way to do it.

In the early stage, if there are not many fish suffering from white spots, we can also use a small soft brush to gently brush off the white spots of the diseased fish, and then cooperate with drugs such as heating, adding salt or adding white spots**.

Other susceptible diseases of fish:

Powdering is one of the most difficult diseases to distinguish from white spot disease, and its cause is mainly due to acidification of water and a large number of algae bursts, which are caused by an eosinophilic oodinoflagellates. In the early stages of the diseased fish, the mucus on the body will gradually increase, and some small white spots will appear at the end of each fin, and the white spots will increase very quickly, as if it is snowing.

This is followed by ulceration and redness at the ends of each fin, and these small white dots will increase in pieces on the body of the fish, as if a layer of powder is applied to the body of the fish, so it is called powdering disease.

Eosinophilic ocuflagellates like acidic water quality, which can be adjusted to a weak alkaline water quality by changing the water in large quantities, or using baking soda and pH test paper, and then combined with an appropriate amount of anti-inflammatory drugs to recuperate the disease.

1. Water quality problems

One of the causes of white spots in fish is water quality problems. When the water quality is abnormal, white spots will appear when the fish body is invaded by pathogenic microorganisms, and it will be accompanied by certain symptoms, such as loss of appetite and slow swimming. Water quality problems include poor water quality, high or low pH, and high ammonia nitrogen levels.

In order to reduce the impact of water quality problems, it is essential to clean the aquarium regularly, replace the water quality equipment regularly, not overfeed it, and regularly test the water quality.

2. Pathogen micro-isolation and biological infection

Another cause of white spots in fish is infection with pathogenic microorganisms. White spot disease is a worm disease caused by filarial parasites. When a fish is infected with a pathogenic microorganism, the immune system responds to changes in cell structure and metabolism that cause the fish to emit powdery and round foreign bodies in the body, which are called white spots.

Common fish pathogenic microorganisms mainly include bacteria, parasites, fungi, etc., when the fish body is found to be abnormal, it needs to be carried out in time to avoid further deterioration of the condition.

3. Malnutrition

Malnutrition is another cause of white spots in fish. In a fish tank, the food that fish eat is their main nutrition. But if they are malnourished, their immune system is affected and they are easily attacked by pathogenic microorganisms, resulting in white spots.

In addition, if the fish body lacks nutrients such as vitamin C, protein, amino acids and trace elements, it will not only reduce the immunity of the fish, but also affect the metabolic function of the fish. Therefore, nutritional supplementation has become an important measure to maintain the health of fish.

4. Other factors

In addition to the above-mentioned factors, white spots in fish can also be caused by other factors. For example, overfishing, too low temperatures, drinking water pollution, high levels of heavy metals in water, water pollution, etc. Therefore, we also need to start from many aspects, comprehensively consider the causes of white spots, and carry out corresponding measures to avoid this situation.
