There are many pests in aquaculture, how to prevent and control parasites in spring?

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.

Fish parasites can be divided into two categories: internal parasites and ectoparasites according to their parasitic sites. Internal parasites refer to parasites in the internal organs, blood, intestines and other tissues of aquatic objects, such as various tapeworms, nematodes, Emeridiasis, schistosomiasis, etc.; Ectoparasites refer to parasites on the body surface, gills, fins, etc. of aquatic animals, such as ring worms, anchorhead catfish, etc., which are easy to spread and are infectious.

1.The environment for fish farming should be thoroughly disinfected to eliminate pathogens. 2.

Fish should be fed in small quantities and often to avoid large feedings to create conditions for parasites to multiply. 3.The chemical ** drugs commonly used in fish parasitic diseases are:

Copper sulfate, ferrous sulfate, mercurous nitrate, potassium permanganate, iodine, thiobis-dichlorophenol and trichlorfon, etc. 4.Commonly used traditional Chinese medicine for fish parasitic diseases, such as Chejing, herbal anthelmintic net, etc.

We are pleased to serve you that the common parasites in aquaculture include fleas, lice, worms and other types, which often bring huge losses to the aquaculture industry. The following are the prevention and methods for several common aquaculture parasites: White Spot Disease:

White spot disease is an infectious parasitic disease caused by protozoa that causes white patchy lesions on the body of fish. Preventive measures include keeping water clean and hygienic, enhancing feed nutrition, etc., and using drugs such as tea-colored drugs and calomite**. Herring parasitic diseases:

Herring parasitic disease, also known as "black spot disease", is caused by a fluke that forms black dot-like lesions on the surface of the fish. Preventive measures are also to strengthen the management of aquaculture water and improve the nutrient intake of fish, and carbaryl and sodium chloride can be used for diseased fish**. Oxygen worm disease:

Oxygen worm disease is also a relatively common parasitic disease of fish, and it is also a disease caused by a parasite that causes the fish body as a whole to show dull and dull symptoms. Preventive measures include keeping the aquaculture water clean and hygienic and nutrient balance, and the drugs are mainly using malanide, trimethoprim, etc.

The results have been found for you: The common parasites in aquaculture are as follows:1

Fish lice: It is a parasite that parasitizes on the surface of the fish body, which will suck the blood and body fluids of the fish body, resulting in anemia, slow growth, and susceptibility to infection. 2.

Fish flea: It is a parasite that lives on the surface of the fish body, which will suck the blood and body fluids of the fish body, resulting in anemia, slow growth, and susceptibility to germs. 3.

Fish gallbladder fluke: It is a parasite that lives in fish gallbladder and can cause problems such as ichthy gallitis and gallbladder effusion. 4.

Gill fluke: It is a parasite that lives on the gills of fish and can cause problems such as gill inflammation and difficulty breathing. 5.

Fish intestinal clonorta: It is a parasite that lives in the intestines of fish, which can cause problems such as enteritis and indigestion in fish. To prevent the occurrence of parasites, the following measures can be taken:

1.Inspect the fish regularly to detect and treat parasites in a timely manner. 2.

Strengthen water quality management and keep water clean and hygienic. 3.Raise healthy fry and avoid the introduction of pathogens.

4.Control the breeding density and avoid over-intensive farming. 5.

Use safe and effective drugs for prevention and treatment. Hope mine is helpful to you<>

Hello dear <>

Common parasites in aquaculture include the following types:1Dermatocystis:

Dermatocystis is a common aquaculture parasite that lives on the surface and gills of fish, causing white cysts to appear on the surface and gills of fish, hindering the fish's breathing and digestion. 2.Hookworm:

Hookworms are tiny parasites that are invisible to the naked eye and can live in the intestines of fish, causing damage to the fish's digestive system and spreading to other fish. 3.Euglena:

Euglena worms can live inside the eyes of fish, causing vision impairment and, in severe cases, blindness. 4.Daphnia:

Daphnia is a common aquatic arthropod that can parasitize the gills of fish, causing black spots on the surface and gills of the fish, which can affect the fish's breathing and digestion in severe cases. 5.Heartworm:

Heartworms are elongated parasites that live in the blood vessels of fish, causing damage to the circulatory system of the fish and, in severe cases, the death of the fish. In response to these parasites, aquaculture owners can take appropriate control measures, such as regular inspections of fish bodies, enhanced water quality management, and the use of drugs. At the same time, it is also necessary to pay attention to the quality and hygiene of the feed to avoid contamination and infection of the fish body.

Summary. Hello is honored to serve you, the common parasites in aquaculture are:1
