Consult a professional about the diseases of koi crucian carp

The disease is certain, and this disease may be a printing disease.

You can find a print disease in the ** to compare, if so, the following is the ** method.

OVERVIEW: A bacterial infectious disease caused by infection of injured fish by the punctate Aeromonobacter bacterium. Mainly due to improper operation, the fish body is injured and infected with pathogenic bacteria.

Symptoms: The lesions mainly occur in the trunk part behind the dorsal and pelvic fins, followed by the sides of the abdomen, and a few occur in the anterior part of the fish. The affected part first appears with a round red spot, like a red seal on the skin of the fish, and then the epidermis decays, the middle part of the scales fall off, and the decaying epidermis also collapses and falls off, revealing the white dermis, and the scales around the lesion site are buried in the decaying epidermis, and the peripheral scales are loose and congested and inflamed, forming a sharp outline.

In the middle and late stages of the disease, it forms a pot bottom shape, and in severe cases, even the muscles decay, exposing bones and internal organs, and the diseased fish dies immediately.

Prevention and control methods: 1. Strengthen feeding management and do not injure the fish. Frequent water changes in the summer can be effective in preventing the disease.

2. Apply the lesion with furazolidone or rivanol 1% concentration.

3. Wash the fish body with a concentration of 20ppm of furacillin or furazolidone, and soak for 20 30 minutes when the water temperature is below 20; 21 32 hours, immersion for 10 to 15 minutes, used as a prophylaxis and early **.

4. Soak the fish body with erythromycin concentration. The water temperature is below 34, soaked for 30-50 minutes, this medicine is only used as **, soaked once a day, can be continuous for 3 5 days, until the condition improves.

Lessons learned: Furans are available in stores and in Livano pharmacies and hospitals.

Whether you can send **, you will know when you see it!

1. Look at the color of the koi fish:

Koi is known for its unpredictable patterns, and patterns are the most intuitive things we can see. When watching, it is necessary to judge according to the requirements of different koi varieties for different colors and patterns. For example, red and white koi fish should depend on whether the white matter is pure enough, whether the scarlet is thick enough, and whether the distribution of the scarlet is uniform and natural, not stiff.

2. Look at the size of the koi fish:

Compared with body shape and pattern, some people pay more attention to body shape, and some people pay more attention to patterns. Generally speaking, the size of the koi fish should be smooth, and the koi fish is known as the "living jewel in the water", which shows the importance of swimming posture to it. A good body shape is the only way to have a good swimming posture.

So how do you choose a koi fish with a better body shape? I usually look at the head first, then the performance of the tail of the koi, and most importantly, the performance of the koi as a whole.

3. Look at the swimming posture of koi fish:

It is necessary to choose a smooth and natural swimming posture, and there will be no abnormal phenomena such as side swimming, leaning, etc.

4. Look at the integrity and luster of the scales and fins of the koi fish:

These points are also very intuitive, you must be careful when you look at it, I once saw that the pectoral fin can move when I picked it and did not look closely, but when I went home and crossed the water, I found that the main bone of the pectoral fin was broken, and it has not recovered until now.

5. There are obvious diseases that can be seen when watching koi fish:

There are seven common pathologies of koi fish:

1) White spot disease: Koi have small, white, and small white spots on their bodies, also known as small melon worms. Don't pick such koi, if the melon worm gets into the gills, there is almost no chance of saving.

2) Mycosis: white hyphae appear on both sides of the fish belly that are easy to be bruised.

3) White hazy disease: There is hoarfrost on both sides of the belly of the fish.

4) Fish lice: Fish lice, like human lice, are a common external parasite.

5) Vertical scale disease: Fish scales are erected on the fish.

6) Worm disease: Fish that suffer from this disease like to swim on the side.

7) Floating head disease: characterized by outliers, head up, tail down, a slight lack of oxygen in the water, especially dog days difficult to survive. It may also be that there is a problem with the swim bladder, which is more difficult**.

In addition to these fish diseases, which can be seen intuitively with the eyes, there are many koi fish diseases caused by improper daily feeding, which need to be paid attention to by aquarists.

Name of the disease, Season of onset, Symptoms seen, Prevention and control methods.

Gill rot disease can be seen throughout the year, generally in spring and autumn Fish sluggishness, detachment, slow breathing or shortness of breath Chlorine dioxide is sprinkled throughout the pool or other bactericidal drugs are used for 2 consecutive days.

Fulminant hemorrhagic disease 3 May Congestion and sluggishness on the surface of the body or at the base of the intestinal fins of the fish Use the bulky stop (benzalkonium bromide) or splash the whole pool of bacterium.

Wheel worm (horse race) 4 August Fish swim sluggishly or in groups along the perimeter of the pond Use copper sulfate ferrous sulfate mixture (5:2) to splash the whole pond.

Oblique tube insect Common in spring and autumn Fish jumping, with a white membrane, sluggish Use copper sulfate ferrous sulfate (5:2) to splash the whole pool.

Ring worms can be seen all year round Fish jumping, gills broken or rotten gills using mebendazole whole pool splashing.

Streptococcal disease In summer, when the water temperature reaches more than 28, the fish's eyes are prominent, the abdomen is swollen, the fish body is black, the liver becomes yellow, the intestine is congested, and the liver is red and swollen The use of three yellow powder (rhubarb and other traditional Chinese medicine extracts) per kilogram of fish body 2 6g feeding, and the whole pool is splashed with trichloroisocyanuric acid for 3 consecutive days.

Water mildew is common in winter and spring **There are villous hyphae on the surface or gills Use thioetherfloxacin (compound propylene disulfide) to splash the whole pool for 2 3 days.

Ulcer perforation Spring **Surface perforation or**Ulceration Use povidone-iodine Splash the whole pool for 2 consecutive days or after catching the fish, clean the lesion with high concentration of potassium permanganate at the sore site.

Small melon worm disease (white spot disease) Winter and spring **There are white dots on the surface, especially at the base of the fish's pectoral fin, use small melons to kill (Artemisia annua and other traditional Chinese medicine preparations) and splash the whole pool for 3 days.

The above is what I summarized in the 10 years of breeding, please do not **! Thank you!

Disease inflammation of ornamental fish koi:

Koi trauma is caused by many common fish diseases, if there is no timely **, it will be infected and inflamed, forming a more conspicuous koi trauma.

The causes of koi injuries are bruises, water spoilage, parasites, tank wiping, etc., when these injuries are not obvious but no measures are taken in time, then it is easy to become inflamed. Especially in summer, when the temperature continues to rise, bacteria and germs multiply, and in the case of external injuries in koi, bacterial infections are formed, which causes inflammation of very small external injuries.

The common inflammatory congestion disease of koi fish is also a kind of koi carp trauma, and the most common is the orbit, operculum, abdomen, caudal peduncle, etc. Sometimes the base of the fin bar is congested, and in severe cases, the fin bar breaks if it is infected. The intestines, kidneys, and liver organs all have varying degrees of inflammation.

Most of the koi fish that are most susceptible to infection and inflammation and the disease are large koi that are older or older than one year old, which may cause a large number of koi deaths. The water temperature during the most epidemic period is around 20-30.

The most common fish diseases such as koi bruises, scratches and other fish diseases are abnormal behaviors such as hitting the tank when they are healthy or under stress, and if there is a little germ in the fish tank, it will be infected and inflamed, making the simple minor illness worse.

The slow growth of koi is not necessarily the cause of fish food, it may be a problem with the tank and water.

If you want the fish to grow fast, you have to use a big tank, how big a tank to raise a large number of fish! In addition, to ensure water quality, fish farming should first raise water, filtration should be strong, and the temperature should be moderate.

Koi eat without moderation, if purely for the sake of growing fast and feeding more, but half the effort, you can consider taking a small meal method, about 4-5 hours apart, feed once, not too much each time!

Generally, they are fed "germ" feed, which will make the koi grow a little thicker! You can also add some lactic acid bacteria, koi will have a great appetite, and if you eat too much, you will naturally be strong. If you want the koi to grow fast, you can feed a little more in the month, the fastest growth of koi in a year is this period, and it will not grow much if you feed too much in winter, and it may also affect the pattern and white matter.

Common diseases of koi fish include acne, athlete's foot, ** inflammation and congestion, erythroderma, slime rot gill disease, whitehead white beak disease, standing scales, printing disease, perforation disease, rotten tail disease, trichinosis, etc. Koi is an ornamental fish, as early as the Ming Dynasty, it was very popular orange bridge. The old koi has a strong physique, bright colors, different species of koi have different colors, it has a magnificent swimming posture, and it is highly ornamental.

Koi fish are not only beautiful in appearance, but also have a very long lifespan and are extremely valuable for breeding.

Koi fish are very adaptable to the environment and can survive between 2-30 degrees Celsius, but the most suitable temperature for koi to live in is 20-25 degrees Celsius. At this water temperature, koi fish are brightly colored, have a strong appetite, swim aggressively, and have a robust physique. Koi fish are the largest of all fish families, with more than 100 species.

Due to the low requirements for water temperature and water quality, it is easy to breed. Koi fish also means good luck, so it is widely loved.
