CATDOLL : CATDOLL: How to treat Saprolegniasis in fish? How to prevent and treat Saprolegniasis in fish?

1. How to treat Saprolegniasis in fish?

1 Saprolegniasis is a common fish disease that requires timely treatment.

2 The occurrence of Saprolegniasis is related to the fish breeding environment, water quality, feed, etc., and attention should be paid to improving these factors during treatment.

3 The methods for treating Saprolegniasis mainly include drug treatment and environmental treatment.

Drug treatment includes chloramphenicol, tetracycline, ofloxacin and other drugs, while environmental treatment requires cleaning and disinfection of aquaculture waters.

Extension: It is also very important to prevent the occurrence of Saprolegniasis. The incidence of the disease can be reduced by strengthening feeding management, regularly checking the health of fish, and keeping the water clean.

At the same time, choosing high-quality feed and fish fry can also help improve fish immunity and reduce the occurrence of diseases.

2. If fish get Saprolegniasis, how to prevent and treat it?

Main function of Wang Iodine: Povidone iodine is the best for killing fungi.

1. Improper feeding and management will prolong the course of the disease or make it worse.

2. The disease will be infected under suitable water environment conditions. Once an outbreak occurs, it is easy to recur if it is not completely cured.

3. Some farmers do not know enough about Saprolegniasis. Once the disease occurs, many will buy some medicines from local dealers (trying all kinds of medicines in a hurry). Whether it can be cured depends on luck. They do not know how to prevent it and have no ability to resist risks.

3. How to prevent and treat Saprolegniasis?

1. Sprinkle a mixture of 250 grams of table salt and 250 grams of baking soda into a 100 cm × 55 cm × 45 cm fish tank. Do this several times and you will see significant results.

2. Dissolve 0.3g of malachite green or methylene blue in 100kg of water, soak the fish for 10-20 minutes, and the mycelium will fall off after a few days. Soak the fish in 1.2%-3% salt water once a day for 5-10 minutes each time.

3. Soak in a malachite green solution of one to two parts per million (1-2ppm) for 20-30 minutes every day.

4. Mix 2 parts per million (2ppm) potassium permanganate with 1% salt water and soak the diseased fish for 20-30 minutes.

Saprolegniasis of ornamental fish

5. Raise the water temperature to inhibit the growth of water mold. A 15-watt ultraviolet lamp can be used for several hours a day to effectively inhibit and eliminate water mold.

This disease generally occurs in low water temperature environments below 20℃ and is most likely to spread in early spring and late winter. Saprolegniasis has no strict selectivity for hosts, and all kinds of farmed fish, from fish eggs to adult fish, are easily infected. Fish in densely-stocked wintering ponds, fish in thin water bodies in spring, or fish in a hungry state are most susceptible to Saprolegniasis. When stocking fish in spring, improper operation can also cause an outbreak of Saprolegniasis.

Disinfection is the main method for preventing and controlling Saprolegniasis. You can choose some milder disinfectants to disinfect the water body, put in some submerged granular bottom modifiers, and then use some drugs to kill Saprolegniasis. The specific method is: Be as careful as possible when the fish enter the pond, and do not injure the fish. Soak the fish in a 3% to 5% salt water solution for 8 to 10 minutes before entering the pond. Avoid handling farmed fish at water temperatures below 15°C to avoid frostbite or abrasions on the fish. If the fish is found to be infected with Saprolegniasis, mix salt and baking soda in a ratio of 3:1 and spray the entire pond at a concentration of 1 mg/L; if the situation is more serious, increase the dosage appropriately. Injured broodstock can be smeared on the affected area with 4% sulfonic wine; fish eggs can be soaked in 4% formalin for 2 to 3 minutes.

Saprolegniasis is a common disease of ornamental fish, which usually occurs in spring, so we must pay special attention to it in this season. No matter what disease the ornamental fish is infected with, it is closely related to water quality and hygiene. Therefore, while we are treating Saprolegniasis of ornamental fish, we must not neglect the daily care of ornamental fish.

4. Can raising alligator turtles in salt water prevent Saprolegniasis?

You can't always use salt water to raise turtles. Generally, salt water is used to disinfect turtles. The salinity and time must be controlled well, otherwise it will be harmful to the turtles.

5. How to treat Saprolegniasis?

This should be a water quality problem. According to my experience, water mold first attacks the dorsal fin and tail fin. I have encountered white head twice, both of which happened when I did not change the water for a long time. My way of dealing with it is not to rush to use medicine. Change a quarter of the water every day for a week, buy some medicinal bath salts and blend them into the tank, and add salt according to the slightly lower proportion in the manual. After a week, check the condition of the fish to see if it has improved. Do not feed during this period. If it has not improved, please use wild yellow powder and add oxygen.

This is the most effective fish medicine I have ever used. It is a bit expensive, but the effect is excellent. There are fakes on the Internet, so be careful to distinguish the authenticity.

Finally, placing the fish tank in a place where it can be exposed to indirect sunlight can effectively prevent the occurrence of water mold disease. However, it will cause algae bloom.

If there is still no improvement, the lesion is clear, and it is confirmed to be water mold, use a diluted solution of povidone iodine or potassium permanganate for a short period of time, and change the water in the entire tank for disinfection. Check the concentration online.

This will cause great harm to the fish body. Usually the fish disease is very serious and I will use drastic measures like this when there is no alternative but to try.

Generally speaking, if you keep the water quality good and keep goldfish in a quiet place for a period of time, they can resist some diseases through their own immunity. All people have to do is to help them create a good environment and use as little medicine as possible.

6. What are the symptoms of Saprolegniasis in turtles?

Cause: Turtles live in water or dark and humid places for a long time, and are not adapted to the water quality. Fungi infect the skin of the turtles. Symptoms: There is no abnormality in the early stage of infection, followed by loss of appetite, physical weakness, or death in hibernation. As the disease progresses, gray-white spots appear on the body surface, head, limbs, and tail, commonly known as "hair growth", and then the epidermis swells, ulcers, necrosis or shedding occurs, and death soon occurs. Saprolegniasis often occurs on the head, neck, limbs and tail of turtles. The hyphae are white, soft, and cotton-like. At first, the sick turtles lose their appetite and become restless. In severe cases, the turtles become thin and weak, do not move or eat, and even die. Chinese flower turtles, Brazilian painted turtles, Nat's painted turtles, and painted turtles are susceptible to this disease. Prevention and control: In the daily feeding and management of turtles, turtles should be exposed to the sun frequently to inhibit the growth of Saprolegniasis and achieve a preventive effect. For sick turtles, you can prepare 4% salt water to soak the sick turtle for 10 minutes, and use potassium permanganate solution to soak and disinfect the breeding container. At the same time, mix an appropriate amount of antibiotics into the food to improve the resistance of the turtle. You can also feed the turtle in 1% spectinomycin solution for a period of time, which also has a good therapeutic effect.

7. How to remedy Saprolegniasis in fish ponds?

Change the water several times, dispose of seriously sick fish harmlessly, and use medication for less serious cases. Boil povidone iodine, sulfofloxacin, salt, baking soda, and gallnut in water and sprinkle it on the pond for disinfection. Because the water temperature in spring is suitable for the reproduction of water mold, which can easily cause fish to become ill, prevention is the key. First, try to continue feeding the fish in winter to give them good resistance.

Second, change and adjust the water appropriately.

3. Do not raise injured fish fry.

Fourth, disinfect with salt water or disinfectant before releasing the fry, and then release them after disinfection. Finally, Saprolegniasis is a disease that is more harmful to fish. Be sure to clean the pond thoroughly to remove the poison and release the fry without any damage.

8. What are the tips for preventing wheat fusarium rust?

Wheat fusarium wilt is a disease caused by fusarium, which is very harmful to wheat. Tips for preventing wheat fusarium wilt are:

1. Plant disease-resistant varieties: Choosing disease-resistant wheat varieties for planting can effectively reduce the occurrence of wheat fusarium wilt.

2. Reasonable fertilization: Wheat needs appropriate amounts of nutrients during its growth period, but fertilization should be moderate. Excessive fertilization can easily lead to poor growth of wheat plants and make them susceptible to diseases.

3. Do a good job in field management: timely weeding, tillage, loosening soil and other measures can effectively reduce the occurrence of wheat fusarium rust. In addition, pay attention to maintaining field ventilation and light, and avoid humid environment.

4. Regular spraying: Chemical or biological pesticides can be used for prevention and control. Regular spraying can reduce the occurrence and spread of diseases.

5. Do a good job of post-harvest processing: After harvest, field residues should be cleaned up in time to avoid the spread of diseases. At the same time, attention should be paid to the storage and preservation of wheat to avoid wheat deterioration and mildew.

The above tips are some basic measures to prevent wheat fusarium rust, which can help farmers better manage wheat fields.

9. What medicine is best for preventing downy mildew?

It is recommended to use benzothiocarb esters to prevent downy mildew. 1. Benzothiol esters are one of the commonly used drugs for preventing downy mildew. Their pharmacological action is to prevent the synthesis of the cell wall of downy mildew fungi, thereby achieving the purpose of preventing downy mildew. 2. Compared with other drugs, benzothiocarb esters have higher efficacy and lower toxicity, can effectively prevent the occurrence of downy mildew, and at the same time ensure the growth and development of plants. 3. When using benzothiocarb esters, the dosage and method of use on the instructions should be strictly followed to avoid problems such as drug residues and drug contamination. At the same time, the use of drugs should be combined with meteorological conditions and the principle of pesticide rotation to achieve the best preventive effect.

10. What are the effective ways to prevent Saprolegniasis in fish tanks?

Measure 1: Maintain good water quality.

Maintaining good water quality is not something that can be solved by simply changing the water. Novices who raise ornamental fish should not be lazy. Remember to clean up the residual bait in the tank in time. If it is not handled in time, a large number of bacteria will breed over time, which is very detrimental to the growth of the fish. Strengthening filtration can ensure that the water quality is in a good state to a certain extent. Fish lovers who have the conditions can grow some water plants, which can also improve the water quality.

Measure 2: Keep the water temperature in the fish tank stable.

The reason is very simple. Sometimes we catch a cold or have a fever. Some people catch a cold or have a fever because of climate change. It is because the external environment is hot and cold, and the body cannot adapt to it and gets sick. In fact, the same is true for fish. If the water temperature is not constant and fluctuates, it will not be able to bear it. Therefore, we should increase the light on weekdays and keep the water temperature not too low. Generally, it is most suitable to control it at 22 to 28 degrees.

Measure three: Disinfect and quarantine the water bodies and filtration systems during the spring and autumn exchanges every year.

When there are no fish in the fish tank, you can directly use potassium permanganate for disinfection. However, in most cases, there are many fish in the fish tank, so I suggest that fish lovers use a basin with a basin of water lightly added with potassium permanganate and pour it into the fish tank. Of course, you can also use some drugs that kill water molds, mix these drugs with salt and baking soda to clean your fish tank. Fish lovers who allow conditions can strengthen the filtration system, and disinfection by heating and oxygen explosion is also feasible.

Measure 4: If sick fish are found, isolate them immediately.

If you find a sick fish, isolate it in time. Do not feed it first, let it rest for a few days. Use coarse salt water to clean the fish during the isolation period, but the hair on its body must be wiped off with a cotton swab. After doing this step, apply medicine to it. Mix potassium permanganate and salt water, and soak the fish for about 20 to 30 minutes for sterilization. Generally, the isolation time is one week, and the medicine treatment must be carried out twice. After it recovers, you don’t have to worry so much, and you can breed it in normal conditions.
