What are the causes of Koi disease in detail?

Many koi keepers have trouble finding someone to answer every question due to a lack of basic knowledge, in which case it is easy to put aside the explanation of the cause of the illness and focus only on the treatment as soon as a fish disease occurs.

In fact, there needs to be an accurate statement about the cause of koi illness. As"If you know the reason why, you must know why (idiom)."If the causes of disease are well understood, it will be more conducive to preventing the disease and treating the symptoms to minimize unnecessary losses.

The causes of koi disease can be broadly categorized as"pathogen initiator"together with"Feed Initiator"Two kinds. Others are"drug damage"Or there are cases where the koi's body is bent out of shape caused by electrocution due to leakage of electricity. However, these are not diseases and are classified as accidents.

I. Pathogen triggers

There are three types of pathogens: parasites, bacteria and viruses. Of these, the insights into bacteria are not yet conclusive, and there has been no progress in the study of viruses.

"(med.) pathogen"Existing outside the fish body refers to the pool. Pathogens are inextricably linked to the environment, the pool water environment in which all pathogens spread. That is, koi and pathogens coexist in the pool. If the fish are healthy, there is less chance of being attacked by pathogens; however, if the health of the fish is impaired or the water environment deteriorates, the pathogens will soon exert a strong force towards the koi.

II. Feed triggers

If you feed your pond with improper feed that has been stored for a long time, spoiled, or is nutritionally unbalanced, it can lead to internal damage and weakened fish, allowing pathogenic bacteria to take advantage of the situation. This is the case, for example, with watermilfoil disease caused by water mold infestation.

        I. Excessive nutrition. Continuous feeding of high-protein, high-calorie feeds will increase the fat in the fish's body, leading to pressure on the heart and causing various diseases of the internal organs. Although koi may look better if they are fatter, it is absolutely forbidden to give them too much feed at one time, resulting in over-nutrition;

     Second, lack of unnecessary nutrients. For example, a lack of vitamins can cause loss of appetite, nervousness, loss of balance, or easy bleeding leading to anemia. In addition cause a slight bulging of the eyeballs or behave abnormally on top of the scales, presenting standing scales;

        Third, do not feed the old feed that has expired. For example, if you feed oxidized silkworm pupae, you will surely get back-thinning disease; small pills available on the market will also be dangerous if they deteriorate, so don't buy too much feed at a time to stock up. It is common sense to keep small pills at a low temperature, and it is strictly forbidden to use anything after the summer in the following year.

        Koi disease those things is the same thing, understand these for the prevention of diagnosis and treatment of koi disease, everyone's heart will have a plan.
