Can aquaculture five yellow kill sporidium?

The five yellow used in aquaculture is the selection of rhubarb, scutellaria, astragalus, cork, rehmannia and Coptis chinensis in five kinds of crushed things, which have the effect of antiviral, sterilization and physical fitness, but there is no insecticidal effect. So if you buy a product that has the effect of killing sporidium, it is either bragging about the skin, or it is also added with chlorphenidine or praziquantel and the like that kill sporidium.

The yellow catfish is a scaleless fish with a thick layer of mucus on its body surface, and it is a demersal fish that loves to eat snails, so it is also often a host for parasites. Common parasites include wheel worms, oblique tube worms, melon worms, anchor head eels, ciliate worms, and so on. When it is found that the yellow catfish has parasites, many aquaculture farmers use any medicine indiscriminately, especially in the past ten years, disease control measures are more and more emphasized, more and more strengthened, and the cost of pesticide application is getting higher and higher.

But this approach often backfires and leads to increasingly severe and difficult-to-treat diseases, as well as increasing losses of dead fish due to parasitic diseases. A large number of frequent use of insecticides, as everyone knows, parasites are inexhaustible, a long time not only damages the health of the fish, reduces the production efficiency, but also will enhance the resistance of the parasite, insecticides are becoming more and more difficult to make, and the special drugs are more and more able to fool people, and then in order to enhance the effect of insecticides, research and development of more toxic insecticides, but the use of toxic drugs, and will bring the risk of dead fish, countless aquaculture practitioners have fallen into the cycle of insecticide and dead fish. In fact, parasites are part of the aquaculture ecosystem and cannot be killed.

If you kill it today, it will appear again in a few days, which is costly and laborious, and it also brings a huge risk that it may cause the pond to turn over. Moreover, most of the external insecticides have high toxicity and high permeability, and the better the effect, the greater the harm to the fish body. The insecticide is sprinkled throughout the pool, and the insecticide will enter the fish body through osmosis, enter the gills, liver and kidney and other solid organs and tissues and injure these organs and tissues, some of the damage is irreversible, and its respiratory, immune, hematopoietic and excretory functions are damaged with the damage, resulting in the normal physiological function of the fish body is affected, and the immunity and disease resistance of the fish body decrease.

In view of the severe parasite problem faced in the process of yellow catfish breeding, we must understand a truth that parasites are preventable and controllable, and the parasites on the fish will cause disease when they reach a certain number, and there will be a small number of parasites on healthy fish, which will not affect the growth of the fish or cause diseases. Therefore, in the process of breeding, compared with insecticide, breeding friends should master the measures to prevent parasitic diseases and prevent them before they occur. Eucalyptus essential oil can be used regularly every month to replace insecticide with insect repellent and prevent **, which can not only effectively prevent and control a variety of common parasites such as wheel worms, sporozodias, ring worms, etc., so that parasites in aquaculture can not multiply in large quantities, so that parasites do not cause morbidity and death, and can also inhibit Vibrio.

Eucalyptus essential oil has a strong and effective repellent and inhibition effect on a variety of parasites such as yellow catfish, such as wheel worms, oblique tube worms, melon worms, anchor head fleas, ciliates, etc., so it is necessary to insist on using Lechang for prevention, so as to achieve fine management, combined prevention and control inside and outside, and lay a good foundation for a bumper harvest and high yield.

If you want to go to the web or mobile phone, there are no restrictions.

In the actual fish disease examination, there are many times when the individual of the original sporidium is too small and does not form a large sporangia, which is not easy to detect. For example, myxosporidium parasitizes the body of fish, for example, the gill filament tissue is sometimes only a little grayish, when carefully picking off some larger white spots with a fine needle, the sporozoides will be found with a high magnification scope. Because the sporozoide is only nearly one percent of its size compared to the small melon worm, it is only a few tens of microns.

The best diagnostic method is to make a preliminary diagnosis based on epidemiology, symptoms and lesions, and to confirm the diagnosis by microscopic examination of cyst compression and microscopic examination of cysts.

Analysis of the causes of sporidium and prevention measures.

Reasons: 1. When selecting seedlings, there is no careful testing, and the seedlings themselves will carry some sporozoans.

2. The original sick pond is not as thorough as the pond, and there are some eggs at the bottom of the pond or there are sporidium in the organic feces during the breeding process.

Prevention and control measures. Sporozoites parasitize in fish tissues, and mature sporidium has a hard shell, ordinary drugs are not ideal for its effect, once the sporangia are formed, the drug is difficult to penetrate into the cysts to cause insecticidal difficulties, there is no special ideal drug at present. The most intractable thing is"Endospores"。

Therefore, the main idea of the control of sporozoides is to focus on prevention and early detection. Many sporidal drugs on the market are difficult to achieve the purpose of completely killing sporidium, generally after killing sporidium with conventional insecticides, sporozoides may start again after a period of time**. Generally, it takes 3-7 days (that is, at least two or more doses) for sporozoids to be eliminated.

Therefore, each stage of breeding should be controlled.

1. Be cautious when selecting seedlings, and strictly implement the quarantine system to prevent the fry from carrying spores.

2. When cleaning the pond, dig out too much silt, use trichlorfon or chlorine preparations to thoroughly clean and disinfect the pond to kill the sporangia in the pond. Try to dry the pond before water injection.

3. Do a good job in water quality management, regularly change the bottom disinfection to enhance water quality, improve the water environment, keep the water quality clean, and maintain good bacterial and algal phases in the pond. Inhibits the growth of bacteria and eggs at the bottom.

4. Regularly use Chinese herbal medicines or plant insect repellents to prevent them, especially in the epidemic months of sporozoides, and appropriately increase the frequency.

5. In the early stage of the disease, an appropriate amount of trichlorfon can be used with levo-mimida hydrochloride and Lechang whole pool splashing, and at the same time, betel nut powder, Chinese herbal medicine, and Lechang can be taken internally to inhibit the proliferation of parasites.

6. For secondary bacterial diseases that may be caused by sporozoides infection. The practical effect shows that the effect of Western medicine is usually more direct and significant, but the toxicity to the fish itself is also obvious, so it is recommended to add florfenicol + Sanhuangsan to the internal regimen to inhibit the reproduction of bacteria in the body.

Don't ask anyone about this kind of thing on the Internet. Don't be so reluctant to pay money, you should go to a technician and let him help you, not just a hammer in the east and a stick in the west, and ask others if this can kill that bug? Can that kill a bug?

For the problem of bleeding and body surface decay caused by parasites, my personal suggestion is that if you don't use Western medicine to deal with it, you should first raise the water in the pond, and the water quality can play a certain role in inhibiting the parasites after the water quality is good. This class of drugs can kill wheel worms, ring worms, etc. Sporozoides, the water temperature is higher, and the water temperature can only be killed when the water temperature reaches 20, and trichlorfon can be killed.

<> Bacterium Rick detoxification is mainly used for the prevention and control of fish bacterial and viral diseases. This product is a compound preparation using plant extract essence, strong permeability, can pass through the blood-brain barrier and reproductive barrier, strong antibacterial, and is a special breeding product. Reservoir aquaculture:

Reservoirs are used as places for local residents to use their domestic water, and it is now forbidden to breed in reservoirs, because feeding and water transfer operations will pollute the water quality during the breeding process.

In recent years, eucalyptus essential oil has been used for prevention and control, and the pure natural extract of eucalyptus essential oil can penetrate the biofilm structure of bacteria and parasites, destroy the integrity of cells, and make bacteria and insects dysfunction play a role in repelling insects and inhibiting bacteria. Strengthen water quality management, so that the water quality is stable, for fish fry it is best to use tender green water to raise, because this water body has a greater buffer force on the environment, and the water quality changes less, which is conducive to the growth of fish and has a certain inhibitory effect on the wheel worm.

For fish farming water bodies, if the oxygen in the water is insufficient, the fish in the pond may not always have floating heads, but it will affect the growth and water quality of the fish, which will be more dangerous in this case. Use the method of hanging the bag to prevent, this method has a certain prevention and control effect for the early symptoms and fish disease season, the drug used in the bag can be used crystal trichlorfon, which is hung around the food table, in short, we must do a good job in the early prevention, strangle all the pests in the cradle, do not do the firefighters who fight the fire everywhere, and do not forget to enhance the immunity of the fish body while sterilizing and deworming.

Taking eucalyptus essential oil 2-3 times a month can effectively prevent and control common aquatic parasites such as sporozodia, wheel worm, ring worm, etc., and reduce the death, injury and loss caused by parasitic diseases. Moreover, eucalyptus essential oil does not harm the fish body, does not affect feeding and growth; Eucalyptus essential oil does not pollute water bodies and does not require detoxification; Eucalyptus essential oil has no drug residues and no safety concerns.

For the prevention and control of parasites, it is mainly to cut off the source of infection, keep the water quality and bottom quality good, improve the fish's own immunity and resistance, and it is best to disinfect at all stages. Fish parasite control has the following aspects: 1. Improve self-immunity.

Appropriate addition of premix addition ratio, eucommia ulmoides leaf extract can be added to the feed to speed up the recovery of physical fitness, enhance the resistance to external parasites.

Lechang eucalyptus essential oil is a safe and non-toxic natural insect repellent, rich in eucalyptus, terpenes and other natural plant ingredients that resist insects and insects. Regular administration of Eucalyptus essential oil in grass carp farming can effectively prevent and control a variety of common parasites such as melon worms, sporozodia, wheel worms, ring worms, anchor head eels, etc. Moreover, eucalyptus essential oil is completely plant-based, without any toxicity, will not damage the fish body, does not pollute the water body, and can be used safely and safely for a long time.

There are many kinds of products on the market that target the wheel worm and the oblique tube worm, such as trichlorfon.

Splashing is very effective against wheel worms. But once used incorrectly or frequently, it will not only cause parasites.

The development of resistance can also cause damage to the fish and the water. Now it is basically a re-use of pure Chinese medicine insect repellent products, Baicao deworming net and Chejing. It is natural, low toxicity and non-drug resistance.

No harmful residues, no pollution, but also can repel internal and external parasites and parasites free in the water body.

1. Trichlorfon: Scaleless fish should be used with caution or prohibited.

Trichlorfon, also known as Masoto. It is white and crystalline, with an aromatic aroma. The commonly used in the market is 90% crystals and 20% and 30% refined trichlorfon powder, which is generally diluted with anhydrous sodium sulfate as a carrier.

Properties: high efficiency, low toxicity, white crystals. Hydrolysis occurs in a neutral or alkaline solution to form dichlorvos, which continues further after hydrolysis and finally decomposes into a substance with no insecticidal activity.

The insect repellent fish drugs used in aquatic products are: trichlorfon, avermectin, pyrethroid insecticides, copper sulfate, and mebendazole.

Then you go to those institutions that raise aquatic animals to consult their ** medicine is for this bug.

"Wuhuang San" is a combination of five medicines, which together form a powerful prescription for fire detoxification. The main ingredients of "Wuhuangsan" are Coptis chinensis, Astragalus poria, Phellodendron chinensis, Gardenia and Astragalus. Among them, Coptis chinensis is berberine, berberine, methylberberine, palmitine and other alkaloids; Huang Ling is a variety of flavonoids such as Huang Ling glycosides, Huang Lingxin, and Hypo Huang Ling; Phellodendron is berberine, cork, palmitine, etc.; Gardenia is gardenia, saffron acid, gardeniaside, gardeniaside, etc.; Astragalus is polysaccharide, choline, betaine, folic acid, amino acids, etc.

Once the ringworm of the fish breaks out in a large area, it is very difficult, and the risk of insecticides is very large, not only will cause damage to the liver of the fish, but also produce drug resistance, there are also drug residues, which is why the fish have not died so much, once the insecticide is used, the fish will die more than before, it is recommended to take eucalyptus essential oil regularly every month to prevent and control the ringworm, a pure plant insect repellent extracted from the leaves of the Australian multi-bud eucalyptus, to drive away the killing, to prevent the treatment, and there is no harm to the fish and water. And it can fight a variety of parasites, fish melon worms, wheel worms, three generations of worms, oblique tube worms, anchor head eels and other parasites.

Summary. Hello, yes!

Copper naphthenate solution has good permeability and has a certain killing effect on cysts formed by sporozoa.

Copper naphthenate aqueous agent is harmful in freshwater shrimp and crabs, can it kill throat sporidium.

Hello, yes! Copper naphthenate solution has good permeability and has a certain killing effect on cysts formed by sporozoa.

What is the harm to shrimp and crabs.

The commonly used drugs to kill small melon worms cannot penetrate into the fish** and reach the "white spots" on the fish body, and cannot kill the small melon worms parasitic on the fish. A variety of drugs are administered by hypertonic, air infiltration or surfactant immersion, and there are few drugs that can kill melon worms in both the schizont stage and the trophozoite stage at the same time.

1.Green water high temperature exposure method.

This is a kind of local method**. Put the diseased fish in a small container with green water, expose it to the sun, and it can be ** after a few days. Because the melon insect is more sensitive to temperature, the suitable water temperature is 16 22.

Green water absorbs heat quickly, and the water temperature gradually rises after sun exposure, and when it reaches more than 26, the insect body falls off by itself. This method is mostly seen in small water bodies when small melon worm disease occurs in ornamental goldfish cultured in tanks.

2.Chili ginger method.

For the chili pepper ginger method, the reputation is mixed, some people report that the effect is very good, and some reflect the effect very poorly. According to the author's observation, chili ginger is properly chosen, and the effect is obvious when used once a year before June 20, the key is that ginger needs to choose sand ginger, and chili pepper needs to be selected Chaotian pepper with high spiciness, and not vegetable pepper, splashed after boiling with water, the effect is obvious. The chili pepper ginger method had a certain effect on the schizont stage of small melon insects, but had no obvious killing effect on the trophozoite stage.

3.Ultraviolet method.

The melon worm is very sensitive to ultraviolet light, and the minimum lethal dose of ultraviolet light to cysts is about 100,000 microwatt-second cm2. The selection of suitable ultraviolet lamps to irradiate the breeding water can kill the small melon insects carried by foreign water sources.

4.Raise the water temperature method.

The elevated water temperature method is suitable for small water bodies. Slowly raise the water temperature to about 30 (the water temperature adapted to the melon insect is 15 20), the melon insect will fall off or die in a poor heat environment. 30 The water temperature is maintained for 48 hours, and then the water is changed generously (change to 30 water), and then slowly cool down to room temperature.

This method is particularly suitable for aquarium farming of ornamental fish in home aquariums.
