What s wrong with my carp... How to save the carp when it is dying

Fish can only be healthy and less sick if they live in a good water environment. The living environment is very important for all living things, and everyone knows that a newly renovated house needs to be vacant for a period of time before it is suitable for habitation. People who work in chemical plants can retire at the age of 45, which fully demonstrates the importance of the living environment to people's health.

Some harms do not manifest themselves all at once, but have a process of accumulation. If one day you find that the fish that used to be active have become listless, anorexic, or sick, it usually means that there is something wrong with the water in the tank, which usually starts with the fish with a weak constitution.

The quality of the water in the fish tank is really important to the fish, and the relationship between the fish and the water is like the relationship between people and the air. Imagine what it would be like for a person to eat and pull in a room without an exhaust fan or flush toilet. If you are in a room with an exhaust fan and a flush toilet, the situation will certainly be satisfying.

So what is the "exhaust fan" of the fish tank, that is, to change the water. Even if an intact ecosystem is established in the fish tank, it is necessary to replace the water in the tank frequently and as necessary, and to increase the activity of the water by replenishing it with new water. As for the "flush toilet", there are two kinds: manual and automatic, manual is to use a straw or sand washer to clean up the solid waste at the bottom of the tank by hand, and the automatic is the automatic extraction function provided by Yongqing filtration.

On the one hand, the Yongqing filtration system provides a large area for cultivating nitrifying bacteria in the tank, which can decompose and transform fish feces in a timely manner and maintain the stability and clarity of water quality. On the other hand, it is actually the automatic "flush toilet" of the fish tank. So that you can enjoy the fun of fish farming more easily.

Cylinder strike? Add large salt or yellow powder.

<> if you find that the carp is dying, you should increase the oxygen content of the water in time. And put the carp into the cold water, and then put the oxygen pump into the oxygen tomb to call the qi, if there is no oxygen chain number gas pump, you can scoop up the water with a scoop, and then pour it down, so that you can also increase the oxygen content of the water.

First 1 4 change the water, put down 4 tablespoons of large grains of salt, after 2 days, then 1 2 change the water, after 4 days, change 1 2 change the water, and then put down 1 tablespoon of large grains of salt... It's good to repeat it a few times, and pay attention to changing the water at ordinary times.

I don't know if it's cottonmouth disease. Whitehead and white mouth.

The pathogen is a species of myxococcus that is morphologically similar to that of the gill rot pathogen Coccus. This bacterium is a good gas growth, the most suitable temperature is 25, the most suitable pH is about about that, and the pH can grow in between.

Symptoms] At the onset of the disease, the cells around the forehead and mouth of the diseased fish are necrotic, the pigment disappears and appears white, and the lesion site is ulcerated, sometimes with gray-white villi, so it presents the symptoms of "white head and white mouth". Symptoms are particularly pronounced in sick fish swimming on the surface of the water. When the sick fish are out of the water, the symptoms are not significant.

In severe diseased fish, the lesion site is ulcerated, and the head of individual diseased fish is congested, and sometimes there are lesion reactions such as white skin, white tail, rotten tail, rotten gills or mucus all over the body. Sick fish are generally thin and black, breathing faster, losing appetite, swimming slowly, constantly surfacing and dying soon after. The disease is an explosive disease with a very rapid onset and rapid contagion, which can kill all people in a single day.

The epidemic is seasonal, generally from late May to early July, with the peak incidence in June.

Prevention and control methods] During the prevention and control, one part per million (1ppm) of bleaching powder can be sprinkled into the fish box for disinfection, or 0.5 to 0.7 parts per million (cilison (containing ethyl chloride) sprinkled in, the effect is very good.

There is also a ** method: choose one gram of furazolidone, dissolve it in ten kilograms of water, and soak the diseased fish for 20-30 minutes. Diluted iodine can also be applied to the wound.

oxytetracyclinum:

Function: Broad-spectrum antibiotic, effective against rickettsia, several gram-positive bacteria and gram-negative bacteria, protozoa, spirochetes and mycoplasma. Low concentration is bacteriostatic and high concentration is sterilization.

Not effective against viruses, fungi and Bacillus aeruginosa. **Bacterial diseases such as gill rot, enteritis and red skin and their fish streptococcal disease, etc.

Usage and dosage: oral: 5 75mg kg per day, for ten days, often used for bacterial diseases such as enteritis and red skin.

Splashing: 2 5g cubic meters of water, once a day, 3 times in a row, can treat bacterial gill rot and so on.

Medicated bath: 25g of a square rice water body medicated bath for half an hour can prevent whitehead and white mouth disease, leukoderma, etc.

Precautions: Same as tetracycline. Store away from light.

The reason for the floating head:

1。It is possible that other fish have also been infected with this bacteria, so be careful not to allow it to spread quickly.

2。Too much ammonia can also float your head. The water quality of your fish is definitely not good, so it is recommended to change a small amount of water. The water should be kept warm and dried for more than two days.

l Landlord! Your carp may have ringworm disease. Ring worms parasitize the body surface and gill filaments of fish, and the inner gill flaps are swollen and grayish-white.

**Method: You can use 0 2--0 4 mg concentration of crystal trichlorfon solution to splash the whole pool. The fish can also be soaked in a solution of 0 2 milligrams of potassium permanganate for 10-30 minutes.

You can't change the water completely, just change a third, and the new water should be cooled, and then the potassium permanganate is mixed into a paste, and it is rubbed on the cyst, and then the potassium permanganate is soaked in it for a while, and it will be pulled

Koi do not have high requirements for water quality, it should be enteritis, buy some Qingda and put it in for 3 consecutive days, and return 1 3 water before adding medicine every day.

There is usually nothing hail in the fish pond. It is omnivorous and has strong disease resistance.

It's just that if the pond is raised by Jian Yu, there are no other fish to match, and there may be raw fish scale disease Tanyan.

It is very likely to be parasitic mump rot, with a mixture of trichlorfon and gills (copper sulfate)**.

Jialufenacillin powder Try.

Your fish has erect scale disease, which has a mortality rate of up to 85%, and in severe cases, the body is sluggish, it has difficulty breathing, the abdomen is up, and it dies after 2 to 3 days. (Be sure to die immediately**, otherwise you will die in a few days, and you have to be separated from other fish, because the infection rate is extremely high).

**Method. 1.Wash the fish body with a concentration of 20 mg kg of furacillin or furazolidone. When the water temperature is below 20 degrees, soak for 20-30 minutes; At 21-32 degrees, soak for 10-15 minutes as a preventive and early **.

2.Sprinkle the whole pool with furacilin or furazolidone concentration, and the concentration can be increased in severe cases, which can be used for prevention and early **.

3.Wash the fish body with erythromycin beam mold kg concentration, the water temperature is below 34 degrees, soak for 30-50 minutes, once a day, for 3 5 consecutive days, until the condition improves.

4.Injection of streptomycin or kanamycin, 120,000-150,000 IU per kilogram of fish, usually only once, and a second injection on the fifth day when the disease is severe.

5.Oral administration with haloperic acid (norfloxacin), powder per 10kg of fish body weight per day, once a day, for six consecutive days.

6.Immersion with rifanol 20mg kg concentration, when the water temperature is 5-20 degrees, immerse for 15-30 minutes; Soak at 21-32 degrees for 10-15 minutes. As an early ** effect is significant.

7.Sprinkle with rivanol concentration all over for special effects.

Using the above treatment methods at the same time as a saline bath, the effect is remarkable.

Topicals. Choose any one of the following kinds of sharp old medicine, and splash it once every other day, a total of 1-3 times;

1) The whole pool is sprinkled with trichloroisocyanuric acid containing 85% of available chlorine, and grams of medicine are discharged per cubic meter of water;

2) The whole pool is sprinkled with chlorine dioxide, and 1 gram of medicine per cubic meter of water should be activated with citric acid or acetic acid before splashing;

3) After the whole pool is sprinkled with gallnut and ground, soak it in boiling water, and put 2-4 grams of medicine per cubic meter of water;

4) The whole pool is sprinkled with bleaching powder containing 60% of available chlorine, and the medicine is discharged per cubic meter of water;

5) The whole pool is sprinkled with sodium dichloroisocyanurate containing 60% of available chlorine, and the water is released per cubic meter;

6) Soak the fish body in 3% salt water for 10-15 minutes;

7) Put 5 grams of copper sulfate, 2 grams of ferrous sulfate, and 10 grams of bleaching powder in 1 cubic meter of water to soak the diseased fish for about 10 minutes.

Take the medicine internally. At the same time as pouring disinfectants, it is necessary to feed granular medicine with good stability in water. You can choose one of the following;

1) Add 2-3 grams of compound oxazole mixed feed per kilogram of feed for 4-6 days, of which the dosage is doubled on the first day, and fed 2 times a day;

2) Add 2-4 grams of sulfonamide-6-methoxypyrimidine to each kilogram of feed and feed for 4-6 days. The dose is doubled on the first day;

3) When the broodstock is seriously ill, it can be injected intraperitoneally or intramuscularly with streptomycin sulfate, per thousand.

20 mg per kilogram of fish injection, or 3 ml per kilogram of fish injection.
