Treatment and Prevention of Koi Congestion

The causes of congestive disease are currently three common conditions; the last three are rare

"one" radical in Chinese characters (Kangxi radical 1). Stress-induced

1) When there is too big a temperature difference during a water change, causing a sudden change in temperature. (As you know, a sudden change in temperature of more than two degrees can have a great effect on koi, and more than five degrees can cause koi fish to die);

2) of newly imported fish to local water qualityPHvalues, softness and hardness are not adapted;

3) Congestion caused by a violent reaction due to the stress of the koi fish when they are caught.

stupid (Beijing dialect). Congestion due to bacterial infection

1) What tends to happen is cross-contamination that occurs when there are old fish in the main tank and new fish come in;

2) unclean water, caused by trauma, not kept in bare tanks or with hard objects in the tank, fish bumps and injuries.Scratches cause infections

Prevention:

1) Newly imported fish should be treated with insecticide and sterilization according to the procedure, and kept in isolation for at least one week without any disease before the tanks can be combined;

2) Regular water changes, maintain good water quality, fish in a good water environment has a very good self-healing ability of.

surname San. Caused by an ectoparasite

They cause koi congestion by mechanically irritating and damaging the skin and tissues, which from time to time can be infected with bacteria.

1) mechanical irritation and damage, a characteristic shared by parasites such as the parasitism of Lepidoptera, which use their mouthparts and barbs on the dorsal armor covering to puncture and tear the skin of the host (the organism on which they are parasitized); and the parasitism of Lernaea major, which can cause inflammatory oedema and cellular hyperplasia in the gill tissues of the host, resulting in gill lesions.

2) Squeezing and blocking Some parasites in koi may cause compression of host tissues and organs, resulting in atrophy, necrosis and loss of physiological functions.

3) Robbing the host of nutrients Parasites derive their nutrients from the host, which can cause malnutrition, slow growth and development of koi fish for a long period of time, and in severe cases, the death of koi fish.

4(Toxin damage) The excretions produced by the metabolism of the parasites during parasitism will remain in the host, and some parasites also secrete toxic substances in varying degrees, which can also affect the health of koi over a long period of time.

The conditions that are likely to cause parasites are mainly the feed given to the koi, especially animal feed, which is not treated cleanly after the koi have devoured it, the parasites will be used as a host and survive, and then reproduction will bring great harm to the koi.

Prevention:

1) The cause of parasites is also the relationship between water quality, we have to do a good job of water quality maintenance, regular, diligent water change, water change to trap water, just hit the water to do the treatment, in addition to removing chlorine in the water but also to remove microbial organisms in the water, the density of koi fish should be raised reasonably, and there is a strong filtration system.

2) Regular worming, new fish must be sterilized and wormed;
