CATDOLL : CATDOLL: How to use erythromycin to control diseases in ornamental fish?

1. How to use erythromycin to prevent and treat ornamental fish diseases?

How to use erythromycin to prevent and treat diseases in ornamental fish? The antibacterial spectrum of erythromycin is similar to that of penicillin G, but slightly broader than that of penicillin G. Gram-positive bacteria and some Gram-negative bacteria are more sensitive to it. Bacteria are prone to develop resistance to erythromycin, but the resistance is not lasting and sensitivity can be restored after 3-6 months of discontinuation of the drug. The drug concentration in each organ reaches the maximum value 1-3 hours after oral administration. It has a synergistic effect when used in combination with streptomycin and sodium bicarbonate. (1) Oral administration: Prepare bait at a concentration of 100 mg/kg body weight and use it for 21 consecutive days to prevent and treat bacterial fish diseases. (2) Spray the entire pond: ① Spray the entire pond with a concentration of 0.2 mg/L and bathe the diseased fish in 2% saline for 15 minutes every day for 3-4 consecutive days to treat vertical scale disease in goldfish. ② Spray the entire pond with a concentration of 0.4-1 mg/L to prevent and treat fin borer disease and tail rot in goldfish.

2. How to prevent and control coccidiosis in fish?

Coccidia are divided into intestinal coccidia, cecal coccidia and chronic coccidia. Intestinal coccidia birds are emaciated, with white manes and feathers. They pass brown bloody stools. Cecal coccidia are characterized by fluffy feathers, drooping wings, white manes and feathers. They pass bright red bloody stools. If not treated in time, the mortality rate is over 50%.

Chronic coccidia such as giant Eimeria produce orange soft stools containing foam and a small amount of blood. Prevention and control measures;

1》Strengthen feeding management and carry out regular prevention.

2》Isolate sick poultry when found 3》Administer damiprol, metronidazole and metronidazole to drinking water.

3. Disease prevention and treatment of angelfish?

Conventional methods can be used for daily prevention. The main way is to maintain good water quality and do not feed fish worms from the river casually to prevent parasites from mixing in. At the same time, you can add coarse salt and fish medicine for prevention (a small amount is OK).

4. How to prevent and treat fish curvature?

Fish will struggle before they die, so most of the time their bodies are bent. If you want to know the cause of death, you need to look at other characteristics; another type of fish is that its body is already bent before it dies. The S-shaped body is a very difficult disease to cure. Long-bodied fish will bend, and short-bodied fish will somersault. The more species of fish you raise, the more experience you will have.

Fish farming needs attention:

1. General household tap water is fine, but tap water contains chlorine. We need to use a fish tank or other water basin to fill it with tap water and leave it for at least 24 hours to wait for the chlorine in our hands to evaporate. This is healthy;

2. Put the fish you bought into clean water and sprinkle a little fish sterilization salt to sterilize the water;

3. Pay attention to the feeding of fish. Fish are not afraid of hunger but they cannot stand fullness. If you keep feeding fish, they will keep eating until they are full to death. Normally, you only need to feed fish once every 2-3 days.

4. Don’t raise too many fish at one time. If your fish tank is small, raising too many fish will cause oxygen in the water. It would be best if you buy a small air pump for fish farming.

5. When you first buy fish, please note that you should not change the water or feed them for 2-3 days;

6. Change the water for fish once every 5-7 days, and feed them once every 3-4 days. Fish are not afraid of starvation, but they cannot stand being full.

7. It is best to use soda water to clean the fish tank. If you don’t have soda water, just use clean water or tap water. Never use soap or detergent to clean it.

8. If you find abnormalities on the fish's body or head, or white or yellow spots, it may be due to excessive bacteria in the water. You should sprinkle some bactericidal salt on the abnormal parts and change to clear water in time.

5. How to prevent and treat fish colds and frostbite?

[Reason] Fish are cold-blooded animals, and their body temperature changes with the water temperature. When the water temperature changes drastically, either a decrease or an increase will stimulate the nerve endings in the skin, causing a disorder in the activity of the internal organs and causing a cold.

When the temperature is low for a long time, the fish will be frostbitten and the muscle tissue will be dehydrated. [Symptoms] The skin of the sick fish loses its original luster and secretes a large amount of mucus.

When the water temperature suddenly changes by 12 to 15 degrees Celsius, carp will go into a state of shock, lying on their side on the water surface and losing the ability to swim.

Bream, crucian carp and carp will die within 3 hours if they are moved from water at 21℃ to water at 1-2℃.

When the temperature is below 4℃, carp will suffer from paralysis, stiffness and imbalance. Under the influence of long-term low temperature (below 1℃), the ends of the gill filaments of carp will swell, which is very similar to frostbite in warm-blooded animals.

6. How to prevent and treat fish mullet disease?

Summer is the best period for fish growth and development, and it is also the peak period for fish diseases. Common fish diseases include infectious fish diseases, parasitic fish diseases and pond flooding. 1. Common fish diseases in adult fish farming 1. Infectious fish diseases: Infectious fish diseases include hemorrhagic diseases caused by viruses and enteritis, red skin and gill rot caused by bacteria. These three diseases are also called the "old three diseases". Preventive measures are: ① Spray the entire pond with 1ppm bleaching powder or a mixture of copper sulfate and ferrous sulfate (5:2) at a concentration of 0.7ppm 1-2 times every 10-15 days; ② The use of drug hanging bags for flow-through farming is more effective, and a course of treatment is hung every 10-15 days. You can use a mixture of copper sulfate and ferrous sulfate (5:2) of 150 grams per bag, or bleaching powder of 250 grams per bag into the water, and hang it for three consecutive days. You can also use 5-10 kg of quicklime to spray the whole pond. ③ For hemorrhagic disease, you can use "Kebaoling" produced by Wuhan Keyang to spray the whole pond. Calculated at a water depth of 1 meter, each bottle is 10 mu, or copper sulfate 0.7ppm is sprayed on the whole pond for two consecutive days, once a day. ④ Enteritis, red skin, and gill rot often manifest as complications. You can use Antechlorhydantoin produced by Beijing Zhongda Ant, spraying the whole pond with 4 mu per bottle, or use 1ppm bleaching powder to spray the whole pond. 2. Parasitic fish diseases: Parasitic fish diseases include Chinese mullet, ringworm, anchor mullet and fish mullet diseases. You can use "Kechongwang B" produced by Wuhan Keyang, spraying the whole pond with 5 mu per bottle, or fish dichlorvos produced by Beijing Zhongda Ant, 4 mu per bag. 2. Common fish diseases of fish species 1. Infectious fish diseases of fish species: Common diseases include enteritis, red skin, gill rot, white head and white mouth, tail rot, etc. The treatment measures are as follows: ① The treatment of enteritis, red skin, and gill rot is the same as that of adult fish farming; ② White head and white mouth, calculated based on an average water depth of 1 meter, use 15 kg of quicklime to spray the entire pond; ③ Tail rot is also called tail stalk disease, calculated based on an average water depth of 1 meter, use Antechlorhydrin to spray the entire pond with each bottle of 4 mu. 2. Parasitic fish diseases: The treatment of parasitic fish diseases such as Chinese mullet, ringworm, anchor mullet, and fish mullet is the same as that of adult fish farming. In addition, there are parasitic diseases caused by protozoa, such as wheelworm, oblique tube worm, and small claw worm disease. Wheelworm and oblique tube worm can be treated with a bottle of cyproconidia B, 5 mu per bottle, or 0.7ppm copper sulfate and ferrous sulfate mixture (5:2) sprayed throughout the pond. The treatment of microcarposis can be treated by spraying 1-2 g/m (water depth) of methylene blue throughout the pond. 3. Flooding: Flooding is very easy to occur in ponds in summer. It is a phenomenon of fish death caused by insufficient dissolved oxygen in the pond water, which often occurs from May to September. Under normal circumstances, when the weather is hot and humid, the pressure drops on cloudy days, and after heavy rains, foam will appear in the pond with fishy smell, and fish and shrimps often float on the water surface and gather at the edge of the pond. The preventive measures are as follows: 1. The transparency of the pond water should be maintained at 20-25 cm, and the water should be changed every 10-15 days. If the water concentration is too high, new water should be added in time. If the water source conditions are poor, a water storage pool can be set up. Turn on the machine for about 2 hours at noon on sunny days. 2. Pay attention to the pond inspection. If flooding is found, turn on the aerator immediately, inject new water at the same time, and reduce or stop feeding. 3. Spraying the whole pond with alum or gypsum powder also has a certain effect.

7. Disease prevention and treatment for meat dogs?

Disease prevention and control mainly includes the prevention of common diseases, frequently occurring diseases and infectious diseases. Although some diseases cannot directly cause the death of animals, they can reduce the use value of animals and their products to varying degrees. For example, skin diseases caused by surface parasites can cause damage and reduce benefits. In particular, some major diseases will directly endanger the health and reproduction of animals, and even endanger their lives, causing breeders to suffer huge economic losses.

8. How to prevent and treat common hedgehog diseases?

Wild hedgehogs may carry infectious pathogens such as tetanus bacillus, plague bacillus, brucella, anthrax bacillus, hemorrhagic fever virus, etc., but domesticated hedgehogs should not have such pathogens. However, to ensure safety, in addition to keeping a safe distance from hedgehogs and avoiding punctures (bites), you can regularly spray the hedgehog's home with 84 disinfectant. When spraying, the hedgehog should be moved away.

9. Common diseases of domestic pigeons and their prevention and treatment?

The common diseases of pigeons are as follows: 1. Indigestion. This is caused by overfeeding, insufficient water or eating unclean feed and water.

10. What are the methods to prevent and treat fish white skin disease?

Treatment methods: (1) Thoroughly clean and disinfect the pond; regularly spray 50ml/mu of mold net or 50ml/mu of dithiocyanate methane; (2) Orally take Lifuyukang + high-efficiency immune polysaccharide + high-energy immune VC mixed with bait for feeding, and use it for 5-7 days; 1. Pathogen: White-skinned Pseudomonas aeruginosa 2. Symptoms: When the disease begins, the disease develops at the end of the tail fin and quickly spreads to the back half of the fish's trunk. The spread part appears white, so it is also called white tail disease. In severe cases, the tail fin of the diseased fish rots or is incomplete. Soon, the head of the diseased fish is facing down and the tail is facing up. It struggles and flows in the water and soon dies. 3. Epidemic situation: The epidemic season of this disease is from June to August 4. Prevention methods: (1) Thoroughly clean and disinfect the pond; regularly spray 25ml/mu of mold net or 25ml/mu of dithiocyanate methane. (2) Orally take Lifuyukang + high-efficiency immune polysaccharide + high-energy immune VC mixed bait and feed it for 5-7 days.
