Eight of the burden, which may cause disease Koi

Unlike most other fish is vulnerable due to the process of selective breeding, which has undergone centuries of koi is the immune system. Keepers were more concerned about strengthening its aesthetic attributes (for example, colors, designs and models) instead of strengthening its ability to fight against the disease.

The number one disease causing agent for most of the fish koi is stress. Stress renders koi immune system vulnerable to infections, its ability to produce the antibodies is compromised during these periods of tense.

Your priority is to control or eliminate stress on your koi. Keep in mind that the extreme changes in their environment and the existence of a burden and cause damage to the fish. Common koi burden are the following:

1. High ammonia in pond water. Check the integrity of your biological and mechanical filtration systems, as well as the clarity and purity of your pond. Ammonia causes tissue damage and slows their growth.

2. poor water Quality. Buy a test kit and check the pH, kh, gh, nitrite, ammonia, and salinity levels in the pond water.

3. Low dissolved oxygen level. You have provzdušnovacu installed to oxygenate the water? The water should be strongly moving and flowing so the oxygen will be evenly pond.

4. handling and movement of fish. Mucous membrane layer which covers the whole body of your koi should be treated with moistened hands, for example. It is the first line of defense against water-borne parasites, irrelevant and fungal, viral and bacterial infections in fish. Fish processing incorrectly will damage this protective covering, which contains antibodies and lyzosome, the enzyme that destroys the cell wall of bacteria.

5. the Crowding. Take care that the equivalent stocking level in your pond is proportional to its soundness. Too many kois and will be tougher competition for food, space and oxygen, among others.

6. the Parasites, such as the tail, costia, trichodina, chilodinella, and "ich". Koi are usually obtain parasites from other fish; often, when a new fish introduced into the pond without quarantine.

7. sharp edges, in or around the pool, fish skin, can impoverished finally expose the parasites and infections. In particular, the spawning tank to ensure that the edges are rounded to the male and the female may bruise injuries during mating time.

8. lack of or inappropriate food. Although kois love worms, he thinks that you don't feed the larvae, which feed on rotten meat and therefore are potential carriers of diseases.

Detection of stress. But how will you know if your kois stress?

Always follow your koi behavioral or physical changes. Pay attention to the apathy, lethargy, lack of appetite and aloneness. If such behaviour persists for several days and the number of kois, you should be concerned.

Check the fish for any bruising, abrasions, ulcers and lesions, which have shaped or there have been days or weeks. Your check in time when they come to the surface to feed. Scanning the gills, fins and skin, where most of the parasites and infection initially raised. If you suspect a more serious illness, peeling for sample and dispatch to the laboratory.
