Why do fish wings rot Is it that the fish are sick?

Rotten fish wings can be caused by a variety of reasons, including poor water quality, changes in water temperature, fish diseases, parasitic diseases, other diseases, and drug factors. All of these factors can cause fin decay.

Poor water quality is one of the common causes of rotten fish wings, and excessive levels of ammonia nitrogen in the water can lead to spotting on the fins. Sudden changes in water temperature, especially in winter, can easily injure the fins of the fish, and bacteria can invade the wound and multiply to produce toxins, resulting in fin rot. Fish diseases, such as fish plague, erythroderma, gill rot, etc., can also cause fin rot.

Parasitic diseases, such as water mildew, melon worm disease, gill rot disease, etc., will grow a lot of small white spots on the fish body, or yellow water, when water mildew or melon worm disease spreads on the fish, the fish will have scales falling off, fin rotting, ** ulceration and other symptoms. Other diseases, such as water mold and enteritis, can also cause fin ulceration. Drug factors are also a cause of rotten fish wings.

If the fish wings rot, it is necessary to take timely measures, such as improving water quality, proper heating, medication**, etc. The specific treatment method should be determined according to the type of fish and the specific situation.

Yes This situation occurs mainly in two cases.

The first, the fin.

The wings you are talking about) were traumatized, and due to the presence of a large number of bacteria and fungi in the natural water bodies, they were easily infected, so they rotted.

Second, there is an outbreak of some kind of infectious disease in the population of fish, like malaria in humans.

Influenza ......The same causes the fish to decay in parts.

Summary. It may be a precursor to illness, or poor water quality. There are many reasons for this. But you can start from two aspects, one is the water quality, the other is feeding, what is the disease of fish wings not opening.

It may be a precursor to illness, or poor water quality. There are many reasons for this. But you can start from two aspects, one is the water quality, the other is feeding, there are many reasons why the fins do not open, but in the final analysis, the fish feel uncomfortable, it may be that the slag is not adapted to the new water, or the temperature is relatively low.

If it is because it is not suitable for the new water, what needs to be done is to rest, and it is forbidden to change the water and feed during the period, which will make the water body slowly deteriorate, and the rest can allow it to recover slowly. If the temperature is relatively low, you need to increase the water temperature, up to 2 per day.

1. What is the disease of fish fin loss?

Fish fin loss can be caused by a variety of reasons, such as bacterial infections, viral infections, fungal infections, water quality problems, nutritional imbalances, and so on. After determining, you can choose to search and flush the rubber suit.

2. Water quality problems cause fins to fall

Water quality problems are a common cause of fin dropping, and if the water quality is too bad, it can have a toxic effect on the fish body, leading to various problems on the fish body, including fin dropping. At this time, the water quality problem can be improved by strengthening water quality testing and water quality adjustment, and for those fish that have already suffered water quality damage, the damaged fins can be repaired by increasing the water temperature, replacing the water with new water, and adding activated carbon.

3. Fin loss caused by bacterial infection

Bacterial infections are also the cause of fin dropping, and when the fish body is infected, there may be redness, swelling, ulceration and other phenomena around the fins, causing the fins to fall off. At this time, biological agents should be added to the breeding environment to cultivate a certain amount of beneficial bacteria, enhance the resistance of the bacterial population, and achieve the effect of reducing or rapidly eliminating harmful bacteria. For serious bacterial infections, special bacterial drugs can be added to the breeding environment to infect.

4. Fin drop caused by unbalanced nutrition

Unbalanced fish nutrition can also lead to fins dropping. Malnutrition or overnutrition can be the cause of fin dropping. In the process of feeding, the amount of meals and the types of food should be appropriately controlled according to the different characteristics of different fish species.

In addition, attention should be paid to the mental state of the fish, and should not be over-fed, over-fed, etc., to ensure the balance of their nutritional needs.

This is a bad tail disease.

**: In the early stage of the disease, the whole pool can be poured disinfectant 1 3 times**. However, when the disease is severe, it is necessary to take medicated feeding while pouring disinfectants outside

Every 100 kg of fish is mixed with 15 grams of Yutai No. 8 medicine every day, and it is fed twice in the morning and afternoon, and it is fed for 5 7 days. However, when the breeding broodstock is seriously ill, it has lost its appetite, and it is necessary to inject streptomycin sulfate intramuscularly at the same time, with 20 ml per kilogram of fish at the same time. One more injection may be given if necessary.

Rotten tail disease is a common disease, whether it is in fish ponds, aquariums, cages, pens, pens, reservoirs cultured grass carp, spotted catfish, tilapia, eel, Oriental pufferfish, carp, crucian carp and other freshwater fish can often occur. As long as the tail of the fish is bruised, or damaged by parasites, the resistance of the fish body is reduced, the water quality is relatively dirty, the breeding density is high, and there are more pathogenic bacteria in the water, it is easy to break out and cause a large number of fish species to die; Adults also suffer from the disease, but the mortality rate is generally low.

Fin rot is more common in environments where water quality conditions are severely deteriorated and bacteria are abundant. The decay of the fins is mostly the tail fin decay, but it is not very harmful and generally does not endanger the life of goldfish. **The method is also very simple, just use potassium permanganate crystals to burn off the rotten tissue.

You can also put an appropriate amount of potassium permanganate crystals in a small container, use the rotten fish fin as a broom, and sweep back and forth on the potassium permanganate crystals. When the decaying tissue has been ablated clean, it can be stopped. Similarly, after the end, it is necessary to rinse the residual medicine with clean water before putting it back into clean water for recuperation.

According to the summary of practical experience, potassium permanganate is the best drug for fin rot. On the other hand, the efficacy of powdery fin rot is quite limited, limited to the deterioration of water quality or bacterial infection, and is not applicable in all cases.

Change the water frequently, as poor water quality leads to bacterial infection.

Clean the filter media in batches. Put rotten meatballs in water + salt according to the amount. |

Hello dear, the cause of crucian carp shark fin rot is: bacterial fin rot. Main symptoms:

The body surface of the diseased fish is inflamed and congested, and the scales are descaled. The fin bars are congested, the fin tips are rotted, and the inter-fin tissues are destroyed. Erythema is common on the operculum and upper and lower jaws, and sometimes the epidermis of the operculum decays, exposing the operculum.

**: Due to the poor water quality, it has been in a turbid state for a long time; Or the fish can't eat enough, and the fish bite each other, resulting in bacterial infection. Prevention and control methods:

Immerse in 3% 4% saline solution for 10-20 min. It is important to maintain the water quality. I hope that Liang Xiao can help you.

1.There are many ulcers, such as those caused by trauma during salvage, transportation or water transfer, and bacterial infection ,..

2.First of all, you need to change all the water in the fish tank.

3.Remove the Arowana and put it in a small vessel, put a small amount of potassium permanganate (the water is pale pink, do not overdose) and soak for 20 minutes, once a day, and at the same time filter and equipment in the original fish tank.

4.Add a little iodized salt to the newly replaced fish tank.

5.The ultraviolet light in the fish tank is turned on and irradiated for several hours a day.
