Hangtai Aquarium: try the following methods if you don't prevent fish from getting sick

The ecological prevention of ornamental fish disease is a "permanent cure", while the active, correct and scientific use of drugs to treat fish disease is a "temporary cure". In line with the principle of "curing both the symptoms and the root causes", it is necessary to effectively treat ornamental fish diseases or delay the spread of fish diseases and reduce losses.

I. General principles for the treatment of ornamental fish diseases

"Detection at any time, early detection, scientific diagnosis, correct medication, active treatment, treatment of both symptoms and root causes" is the general principle for the treatment of ornamental fish disease.

Specific principles for the treatment of ornamental fish disease

Water before fish

"treat the Gill first, treat the Gill first and treat the water first". Various Gill diseases are one of the most important diseases that cause the death of ornamental fish. For ornamental fish, Gill is more important than heart, because Gill is not only an important place for oxygen and carbon dioxide gas exchange, but also a place for calcium ion, potassium ion, sodium ion, ammonia and urea to exchange excreta. Therefore, only by treating Gill disease as soon as possible and improving its respiratory and metabolic function can it be beneficial to the prevention and treatment of Gill disease. The changes of ammonia, nitrite and excessive acid or alkali in water environment directly affect Gill tissue, respiration and metabolism. Therefore, we must first control the ecological environment and accelerate the metabolism of the water body.

First outside and then inside.

First control the external environment, that is, including water, bottom sand, and fish body surface, and then treat internal, that is, visceral diseases, that is, first treat various body surface diseases, which is also relatively easy to treat fish diseases, and then treat visceral organ diseases through bait and injection.

The Beginning of Summer Sanhou

Mole song: the Beginning of Summer's day "mole song". According to Zheng Xuan's explanation in the Eastern Han Dynasty, "mole cricket" is a frog, not a mole cricket (l ó u galley). Li Xia Ming is said to be a kind of brown and black frog. Earthworm birth: five days after the Beginning of Summer, "earthworm birth". Earthworms, also known as qu qu, long sing in the ground, feeling Yin Qi and qu, taking advantage of Yang Qi and see. Wang Guasheng: five more days, Wang Guasheng. This king melon, also known as "soil melon", "melon is like hail, ripe is red, crows like to eat it, so it is called 'old crow melon'", not cucumber.

Worms before bacteria

Parasites, especially large parasites, have a strong ability to destroy the body surface of ornamental fish, and the wound is the way of bacterial invasion and infection, resulting in a variety of complications, so the prevention and treatment of parasites has become the first step in the prevention and treatment of fish disease.

Third, common administration methods for ornamental fish disease.

Among the diseases of ornamental fish, infectious diseases and parasitic diseases caused by pathogens account for the vast majority. Therefore, killing these pathogens with drugs is the most important measure to control the diseases of ornamental fish. The method of medication is very important for the prevention and treatment of the disease of ornamental fish. we should choose different methods according to the type of disease, the condition, the species of fish, the way of feeding and the purpose of application (whether to treat or prevent the disease). The commonly used methods are as follows:

1. The whole pool sprinkling method

In this method, the water body of the whole fish pond is taken as the application object, and on the premise of correctly calculating the amount of water, the appropriate application concentration is selected to calculate the dosage, and then the weighing medicine is diluted with water and sprinkled evenly into the water body of the whole fish pond. Ornamental fish are raised in water containing drugs and bathed by drugs, which can make the pathogens in the body surface, gills and water of diseased fish come into direct contact with the medicine solution, so as to treat fish disease. This method has a remarkable effect on killing bacteria and parasites in water and on the body surface and Gill of diseased fish, and it is easy to operate, so it is the most commonly used method to prevent and treat ornamental fish disease, but the drug cost is high, and the drug concentration should be avoided. Serious consequences leading to the death of ornamental fish, but also to avoid the concentration is too low, can not achieve the control effect.

2. Bait method

Also known as internal medicine. The specific method is that according to the condition of the fish, the corresponding medicine is mixed into the powder according to the fixed proportion to make the pellet bait or the drug is mixed into the pellet bait, and the drug enters the fish body with the intake of the feed, thus plays a role in the body. This method has a good effect on parasitic diseases, bacterial diseases, vitamin deficiency and other nutritional diseases in the body, with the advantages of more thorough effect, less drug waste and cost savings, while the disadvantage is that it has no effect on fish that are seriously ill and have stopped feeding.

3. Immersion method

Also known as washing method or medicine bath method, ornamental fish are concentrated in smaller containers and higher concentrations of medicine solution for a short-term forced bath to kill bacteria, viruses and parasites on the fish body surface. The specific method is to fill the prepared container with water, calculate the volume, put the drug at one time, stir it up and measure the water temperature after the drug is fully dissolved, and then put the fish into the liquid and remember the time. The activity of the fish should be observed during the whole washing process. if you find it difficult to breathe or there are signs of floating head, the fish can be fished out in advance and put directly back into the pond or into the prepared water. The advantage of this method is that the dosage is small and accurate, and does not affect the growth of bait organisms in the pond, but the disadvantage is that it can not kill the pathogens in the water, and it is troublesome to transfer diseased fish, and it is easy to damage the fish and aggravate the disease. In the fish ponds and aquariums where the running water or changing water is convenient, the water level can be lowered, the running water can be stopped or the flow rate can be slowed down, and the water level and flow rate can be restored after bathing for a certain period of time, and the effect is more obvious. Parasitic diseases are generally washed for 1 or 2 times, and it is best to sprinkle infectious diseases again after soaking.

4. Injection method

It is found that after the ornamental fish is sick, a certain amount of medicine is injected directly into the fish through the syringe, so that it can be absorbed directly in the body, so as to achieve the therapeutic effect. This method is mainly used for the treatment of parent fish and valuable fish, immunization of famous and high-quality fish and seriously sick fish that can not be eaten. Injection methods can be divided into three types: intraperitoneal injection, intramuscular injection and thoracic injection. Most of the intraperitoneal injection is to enter the needle oblique to the pectoral fin along the medial base of the ventral fin. The injection depth varies according to the size of the fish, generally 0.2 to 0.5 cm, and is injected from the upper middle of the ventral fin and the lateral line. After all the drugs in the needle tube are released, slowly pulling the needle can reduce stress and prevent the liquid from leaking out with the needle eye. The intramuscular injection is generally in the scale-free area at the base of the dorsal fin at an angle of 30 °~ 40 °with the fish body, and the needle is injected into the head. The injection depth is not up to the vertebrae according to the size of the fish. It is better to choose drugs that have no stimulation or effect on muscle tissue.

5. Smear method

Also known as smearing method, that is, in the body surface of ornamental fish smear thicker liquid or ointment, in order to kill pathogens, so as to achieve the therapeutic effect, mostly used for the treatment of parent fish, precious fish and individual trauma and local inflammation. The specific operation is to catch the sick ornamental fish and smear the medicine directly on the wound. This method has the advantages of low dosage, convenience, safety and small side effects, but the disadvantage is that it can not be used in large quantities, and attention should be paid to lifting the head slightly when applying the drug, so as to avoid the harm caused by the drug flowing into the oral cavity and Gill.

6. Hanging medicine bag (basket) method

Put a permeable bag (or bamboo basket) filled with a certain amount of medicine into the water to slowly release the drug, creating a drug area with a certain concentration in the pool water, so that the ornamental fish can come out of the area freely within the drug concentration range that can be tolerated, so as to achieve the purpose of killing pathogens on the body surface and Gill. The utility model has the advantages of saving drug cost, convenient operation and little pollution to the water body, but it does not kill pathogens thoroughly, so it is only suitable for the early treatment of pre-and disease.

7. Immersion retting method

Chinese herbal medicine is bundled into bundles and soaked in the upwind or inlet of the fish pond to spread the effective ingredients to the pond so as to kill or inhibit the pathogens in the body surface and water of ornamental fish. This method of drugs play a slow role, generally only applicable to prevention.

Any method should be operated with reference to the actual situation. Well, I hope this article can help you.
