Prevention and treatment of common diseases of map fish

Many people raise fish at home, arranged in the glass fish tank in the living room and other places, colorful or chic fish swimming around, do not have a mood, many people like to raise map fish, map fish vitality is relatively strong, but do not pay attention to fish diseases will also occur, let's learn about map fish common diseases and prevention methods.

White spot disease

[symptoms] in the early stages of the disease, diseased fish rub hard objects with their bodies, hoping to get rid of unpleasant pathogens. Many small white spots can be seen on the body surface, fins and gills of diseased fish. Diseased fish are emaciated, float on the surface or cluster in a corner, and rarely move. In the later stage, the body surface is as if covered with a layer of white film, the mucus increases, and the body color is dull.

[control] ① can use the method that the white spot worm is not resistant to high temperature to raise the water temperature to 30 degrees. Promote the rapid maturation of spores produced on the surface of the fish, accelerate its growth rate, and make them lag behind from the surface of the fish. ② red potion treatment, the key to this method is not to add more, the water color has been slightly red can, rather less than more! Soak for 5 minutes, once or twice a day. I hope the above information will be helpful to you. If there are any inaccuracies or omissions, please correct and supplement them.

Rotten fin disease

[symptoms] there are obvious defects in the caudal fin and tail, which may spread to the root of the caudal fin and cause more serious diseases if not treated in time.

[prevention and treatment] dissolving 1 gram of furacilin or furazolidone in 10 kg water for 20 minutes or sprinkling with low concentration of ① can restrain the spread of the disease and gradually restore the growth and development of the fins. ② 0.01% potassium permanganate solution can effectively inhibit the spread of the disease.

Bubble disease

[symptoms] Bubble disease is also one of the diseases that map fish are prone to suffer from, but the incidence of the disease is not high. The typical manifestation is that map fish have a lot of small bubbles, mainly in the pectoral fin, ventral fin and abdomen of map fish.

[prevention] ① flushing air, the water temperature should be controlled and stable, so that the supersaturated oxygen in the water body is emitted into the air. ② changes the water thoroughly and drains the old water.

Blindfold disease

[symptoms] White fog appeared on the eye membrane at the initial stage, mostly monocular, the eyeball was cloudy in the middle stage, the eyes were swollen at the end, and white cotton cotton cones grew. If the waiting period is not properly handled at this time, there will be the fear of death.

[prevention] early stage of ①: the phenomenon of white fog in the fish eye membrane was found in the early stage, so you should immediately change the water and add appropriate crude salt with a concentration of 5/1000, that is, 200L water into one jin of crude salt, and heating to 3032 ℃. Observe whether it is improved in two days. If it does not deteriorate, it is necessary to strengthen the change of water, change water 1/4 every three days, and add the right amount of salt, you can be cured. In the middle stage of ②, medication is needed for drug bath treatment. Use water-soluble chlortetracycline, penicillin, or fish-specific drugs. If you use special drugs for fish, you can use them in accordance with the instructions. Chlortetracycline and penicillin are put into 10,000 to 20,000 units per liter of water. When taking a medicine bath, the temperature should be increased by 2 ℃ ~ 3 ℃, and observed, the medicine should be re-added according to the prescription, and the water should be changed by 1/4.

[note] severe eyeball opacity, slow recovery time, about three to five months will be cured. If the swelling is eliminated, the dosage can be reduced or discontinued. After recovery, the black eye will be smaller than before, but it will be all right.

Prevention and treatment of common diseases of map fish should be avoided

1. It is advisable to prevent disease first and seek medicine after avoiding disease. The initial symptoms of fish are not easy to observe, and when diseased fish are found, they often rarely eat or stop eating, which brings difficulties to the use of drugs.

2. It is advisable to prevent regularly and avoid civil and self-defense. The disease of fish has a certain periodicity. For example, fish are prone to water mildew in early spring and late autumn, grass carp and herring in early summer and mid-autumn, and high water temperature in summer is the high incidence season of fulminant fish disease. According to the regularity of the occurrence of fish disease, it can be prevented in advance.

3. Comprehensive prevention should be recommended and single drug use should be avoided. The incidence of fish is the result of comprehensive factors, so the prevention of fish disease must aim at all kinds of pathogenic factors and take comprehensive measures to restrain pathogens, improve water environment and improve fish disease resistance. Including thorough pond cleaning, fish seed disinfection, regular water injection and application of quicklime, scientific fertilization and bait, regular internal and external treatment, etc.

4. Disinfect at low temperature and avoid high temperature medicine bath. Medicine bath is an important method to prevent and cure fish disease. it is generally carried out in buckets or pots when fish are released in low temperature seasons. this method is used in summer because of high water temperature and enhanced drug effect.

5. it is appropriate to use drugs in rotation, and avoid single use of drugs. If a single drug is used to prevent and treat diseases in water, various pathogenic bacteria and parasites of fish will produce drug resistance and reduce the effect of drug use, so the rotation of mixed drugs should be actively promoted, but acidic drugs and alkaline drugs should not be used together.

6. it is appropriate to take medicine at the right time, and avoid taking medicine at any time. The use effect of fish medicine, especially the effect of sprinkling medicine in the whole pool, is closely related to water mixing, dissolved oxygen and light. High water temperature, rich dissolved oxygen and strong light can accelerate the effective speed and improve the efficacy and reduce the side effects. Therefore, the prevention and treatment should be carried out in the afternoon on a sunny day.

7. Appropriate amount of medicine should be used, and the amount of medicine should not be added indiscriminately. The dosage of all kinds of fish medicine is determined after many experiments, which can effectively prevent and cure fish diseases with little side effects. If overused, it not only increases the cost, but also may cause drug damage.

8. Non-metal containers should be used to store soluble drugs, and metal containers should not be used. Fish medicine is mostly chemical synthetic drugs, the chemical properties are not stable, easy to react with metals, the composition and properties are changed. Therefore, containers made of non-metallic materials such as ceramics, wood and plastics should be selected for storage and melting of fish medicine.
