CATDOLL : CATDOLL: What are the symptoms of Ichthyophthirius vulgaris in fish?

1. What are the symptoms of Ichthyophthirius coli in fish?

Fish with Ichthyophthirius will have small white spots on their bodies in the early stage, and the white spots will be connected in the later stage. Fish with this disease will often be listless and have poor appetite. Public platform: Qiu Shui Yu Yue Ornamental fish medication (generally speaking, the method of increasing temperature and adding salt can be used, or ornamental fish can use mercuric nitrate, and there are also finished drugs on the market: White Spot Clear). The number of white spots may increase the day after the first medication. This is the precipitation of Ichthyophthirius in the fish's body. After the second day, if the Ichthyophthirius gradually falls off the fish's body, the white spots on the fish's body can be seen to gradually decrease with the naked eye, which means that the medication has taken effect and the situation has improved.

2. How to prevent and control Ichthyophthirius in fish according to common knowledge in fish farming?

Ichthyophthirius is commonly known as white spot disease. The treatment is to change one-third of the water and heat it to 31 degrees to kill the insects and eggs. No need to disinfect again. The cause of this disease is a large deviation in water temperature when changing water, or a sudden drop in water temperature.

3. How to prevent Ichthyophthirius multifiliis disease?

Ichthyophthirius treatment:

(1) Spray 2 grams of methylene blue per cubic meter of water, all over the pond, several times in a row. (2) Spray 15-25 grams of formaldehyde solution per cubic meter of water, all over the pond, once every other day, for a total of 2-3 times.

Treatment

1. From the perspective of the most stable goldfish, do not use those drugs to treat Ichthyophthirius. After all, all drugs are poisonous. Materials needed are salt, yellow powder, filter, and heating rod. According to the characteristics of Ichthyophthirius that will stop developing when the temperature exceeds 25 degrees and die when the temperature exceeds 30 degrees, when the goldfish is found to have white spot disease, stop feeding it on the same day and start heating it step by step with a heating rod. In the first stage, raise the temperature to about 25 degrees. After about half a day for the fish to adapt, raise the temperature to 28 degrees and add appropriate amount of salt and yellow powder to fight bacteria and inflammation, thereby preventing cross-infection of insect diseases. In the second stage, raise the water temperature to 30 degrees, clean and filter every two days, and then add yellow powder. After three or four days when the white spots completely disappear, slowly restore the water temperature. If the situation is not too serious, it will heal automatically.

2. Soak in 3%-5% saline for 30 minutes, then apply commercially available white spot medicine according to the indicated amount.

3. Apply formalin at a concentration of 30-40 mg/L, and continue to apply the medicine every three or four days until the disease is cured.

4. Add 20 mg/L potassium permanganate, bathe for 10 minutes, return to the tank and wait for recovery.

5. What is the treatment for freshwater Ichthyophthirius disease?

Taking advantage of the weakness of the Ichthyophthirius punctatus that it cannot tolerate high temperatures, raising the water temperature and then providing drug treatment, the cure rate can usually reach more than 90%. If the treatment is timely, the cure rate can reach 100%. Using a mixture of 25 parts per million (25PPm) formaldehyde solution and 0.05 parts per million (0.05PPm) malachite green for treatment has a very good effect; or soaking in 2 parts per million (2PPm) mercurous nitrate solution for 30 minutes; or soaking in 1% salt water for several days, or soaking in 2 parts per million (2PPm) quinine hydrochloride solution at 28~30℃ for 3~5 days; or soaking in 2 parts per million (2ppm) methyl blue solution for 6 hours a day; or spraying with 0.1 to 0.2 parts per million (0.1~0.2PPm) mercuric nitrate solution, all can achieve good results.

6. Sporozoan disease in fish?

First, we need to distinguish the type of disease and the type of fish we are raising. Sporozoa are a large class of pathogenic protozoa, and there are many types. There are many fish disease sporozoa, which can parasitize the mesentery, gills, brain, spinal cord, and internal organs. Iodine bubble worms are the main pathogenic organisms of carp. Generally, prevention and treatment are the main measures. It is too late to infect the fish. Prevention and control methods:

1. Thoroughly clean the pond with quicklime, etc. to inhibit the massive reproduction of spores and reduce the occurrence of this disease;

2. Before stocking the fish, add 500g of potassium permanganate to 1 cubic meter of water, stir to fully dissolve it, and make a solution with a concentration of 500mg/L. Soak the fish for 30 minutes, or add 500g of lime nitrogen to 1 cubic meter of water, stir to make a suspension, and soak the fish for 30 minutes. Treatment of myxosporean disease This disease is caused by myxosporeans parasitizing the skin, gills, intestines and nervous system of fish. The parts of the fish disease have cysts, which are grayish white dots and tumors. Common myxosporeans include pancake-shaped iodine spores, wild carp sulfonium spores, crucian carp iodine spores, silver carp iodine spores, etc. Symptoms: The sick fish are emaciated, the body color is black, they swim alone or restlessly and wildly, and they are extremely harmful to the fish from October to February of the following year. Treatment methods: 1. Sprinkle 1 jin of 90% crystal trichlorfon per mu of water in the whole pond, and sprinkle it again after 3 to 4 days. 2. For every 10,000 fish or 100 jin of fish, mix 75 grams of edible sulfur powder with feed and feed it for one week. 3. Add 10 grams of 90% crystal trichlorfon to each jin of feed to feed fish, which can cure intestinal parasitic myxosporeans. This method is also effective for ringworm disease. Compare the following information, and it is best to consult an expert for specific practices. Other classifications 1. Madness disease is also known as silver carp madness disease, crazy knife, and silver carp iodine bubble disease. It is caused by silver carp iodine bubble parasitism in various organs and tissues of silver carp, especially the nervous system and sensory organs, such as the brain, spinal cord, parasitic lymph fluid in the cranial cavity, nerves, olfactory system, balance, and auditory systems. Silver carp fry can be infected as soon as they emerge from the membrane. At present, in production, it mainly harms silver carp of full age. When the disease is serious, it can cause a large number of sick fish to die; the meat of sick fish is not fresh and has a strong fishy smell, and it is very thin, so the commercial value of the fish that have not died is also seriously affected. This disease occurs in rivers, lakes, reservoirs, and ponds across the country, especially in Hangzhou, Zhejiang. When seriously infected, the sick fish are extremely emaciated, with a large head and a small tail, with an upturned tail. The weight is only about half of that of a healthy fish. The length of the head is 2.95 times the height of the tail stalk (2.2-2.3 times for healthy fish), and the body color is dull and lusterless. The sick fish swim alone in the water, often jumping out of the water and diving back into the water, repeating this many times and dying. When dying, the head often burrows into the mud. Some swim sideways and die due to loss of balance and feeding ability, so it is called crazy disease. When the fish body is cut open, white cysts of varying sizes visible to the naked eye can be seen at the place where the silver carp iodine vesicles parasitize; the liver and spleen are atrophied, there is ascites in the abdominal cavity, and the vagus lobe of the cerebellum is significantly congested; the sick fish are severely anemic. 2. Pancake iodine vesicle disease is a serious fish disease during the grass carp seedling breeding period. It is caused by the parasitism of the pancake-shaped iodine bubble worm, which mainly parasitizes the intestinal wall of grass carp, especially the lamina propria and submucosa of the foregut. It occurs in all fish farming areas across the country, with Fujian, Guangdong, Guangxi, Hunan, Hubei and other places being the most serious. The mortality rate can be as high as over 90%. The fry are infected 12 days after being put into the pond, causing a large number of deaths. When the water temperature is 27-30℃, it takes 12-15 days for the worm to develop a generation in the body of grass carp. When the spores aged for 6-8 months are used to artificially infect grass carp fry, 100% of them will become ill. It mainly harms grass carp with a total length of less than 5 cm, and bighead carp, silver carp and black carp mixed in the same pond are not affected. The disease is prevalent from May to July, especially from May to June. Many small white cysts are formed at the parasitic sites of the pancake-shaped iodine bubble worm, and the cysts are surrounded by connective tissue membranes formed by the host. The body color of the sick fish is black; the fish is emaciated, with a slightly swollen abdomen, light red gills, anemia, no food in the intestines, thickened foregut, and degeneration and necrosis of the intestinal wall tissue; when a large number of pancake-shaped iodine bubble worms parasitize on the spine, the fish body may bend. According to reports from Sichuan Province, pancake-shaped iodine bubble worms parasitize in the muscles of carp fry, forming white cysts. The body surface of the sick fish is uneven, and the fish grows slowly. In severe cases, the disease causes a large number of deaths. 3. Wild carp iodine bubble worm disease Wild carp iodine bubble worms parasitize on the skin and gills of dace fry and summer carp, forming many gray-white tumor-like or dot-like cysts, especially on the body surface. In severe cases, it affects the breathing and swimming of the sick fish.

7. What causes Ichthyophthirius multifiliis disease?

Ichthyophthirius is caused by the invasion of worms. The epithelial cells of fish gills and skin often thicken due to the invasion of worms, which results in the gill filaments being hampered from taking in oxygen. The deformation of gill filaments and gill plates also restricts the circulation of oxygen. The space occupied by parasitic worms also hinders the passage of oxygen through the gill filaments, all of which hinder the breathing of fish.

The detachment of the gill epithelium can also lead to the loss of electrolytes, nutrients and body fluids in the fish, causing nutritional imbalance and damage to the osmotic system of the fish. Furthermore, bacteria and fungi are also prone to secondary infection.

The first is heating treatment: according to the characteristics of Ichthyophthirius spp. that it cannot tolerate high temperature, the water temperature is raised to 28 degrees (Ichthyophthirius spp. cannot reproduce easily when the water temperature is above 25 degrees, and it starts to die at 28 degrees) to prevent and treat it. After a few days, the cysts of Ichthyophthirius spp. will gradually break and fall off. At this time, replace the water with new water and keep the water temperature constant, and the sick fish will basically recover. If supplemented with drug treatment, the cure rate can reach more than 90%.

The second is Chinese medicine treatment: A. Use 29% of schizonepeta, 43% of neem leaves, 14% of wild taro leaves, and 14% of datura purpurogena, mix and boil the juice to twice the original amount, and soak the sick carp to kill the Ichthyophthirius trichosanthis. B. Use 1.5 grams of rhubarb and 1.5 grams of dried wild chrysanthemum per cubic meter of water, and pour the decoction over the whole pond for 3 consecutive days to kill the Ichthyophthirius trichosanthis.

Third, soak the sick carp in 200-250 grams/cubic meter of glacial acetic acid for 15 minutes to kill the Ichthyophthirius multifiliis on the fish body.

Fourth, put furazolidone powder the size of a soybean into an aquarium with 50 kg of dissolved water, dilute it and sprinkle it into the water to bathe the sick fish.

The fifth method is to soak the new bricks in urine for 24 hours, take them out and dry them (called urine bricks in ancient times), and put them in the tank of the sick fish. It will be effective after a few days.

8. What are the patterns of the occurrence of Ichthyophthirius multifiliis disease?

It is a scale insect, and it occurs in large numbers. It is best to use pesticides to control it. Treatment method: The dead leaves should be cut off and destroyed in a centralized manner. Do not throw them away randomly, otherwise it will easily infect other plants. For leaves that are not seriously infested by insects, you can go to the flower shop to buy some 75% acephate soluble powder and use it according to the instructions. It is best to spray the pesticide outdoors and take personal protection measures, especially if there are children at home. Do not let the pesticides be touched by children.

9. How to treat fish infected with Ichthyophthirius?

There are generally two methods: (1) Adjust the heating rod to 32°C, and the actual water temperature will slowly rise to 30~32°C; (2) Use medication. There are many drugs on the market to treat white spot disease, and most common aquarium drugs can cure it. A common type of drug with methylene blue as the main ingredient, such as various universal fish medicines, is relatively mild. After the drug is applied, the water turns blue and it takes more than 10 days to cure. Another type of drug with potassium permanganate as the main ingredient turns the water light red in a short period of time after the drug is applied. It is more effective, but of course the risk of using it is slightly greater.

10. How to treat Ichthyophthirius scoparia disease in koi?

I personally suggest not to raise the temperature too high. The fish will not be able to bear it. Don't raise the temperature too much. Put the sick fish in a container first. Because the white spots are very contagious.

There are only two fish left in my fish tank.

It is basic to pay attention to prevention. Since there are sick fish, there must be bacteria in the water. Remember to disinfect.

I haven't tried the grave you mentioned. I used to buy medicine for this disease and put it in a separate container. But a few fish still died. You must not add edible salt. You must buy special salt. All fish are afraid of salt. Add less salt. One third is enough. I hope my answer is helpful to you?
