How is fish disease prevented? What are the prevention and control methods of fish diseases? How can

As long as the water quality is stable and clear, the fish will be healthy and less sick, and the treatment of the disease is the matter of experts, ordinary people are not good, it is difficult to judge what the fish is sick, not to mention what medicine to use, how much to use. If the fish is sick, if the medicine is not appropriate, the fish disease will be more serious. Fish diseases are mainly caused by long-term poor water quality, just like people, if they live in an environment with bad air for a long time, they are also easy to get sick.

Keeping the water stable and clear is a key issue if you want your fish to be healthy and disease-free. Nowadays, most of the fish are raised in bare tanks, and the advantage of bare tanks is that they are easy to clean, and dirt is not easy to accumulate at the bottom of the tank. However, due to the lack of nitrifying bacteria epiphytic area in the tank, nitrifying bacteria rarely have limited self-cleaning ability, if the density of the fish is large and the feeding is more, and the fish feces can not be absorbed in time, the water body is easy to be turbid in many cases.

Because the BB of the fish cannot be decomposed and transformed by nitrifying bacteria in time, the ammonia nitrogen in the tank exceeds the standard, and the fish is easy to get sick or even die. The Yongqing filtration system removes the ammonia of fish feces by cultivating a large number of nitrifying bacteria in the biochemical mesh plate and bottom sand in the tank. Under the net plate, a directional flow of water is generated to guide the dirty things to the water inlet to be pumped out and filtered out, so as to keep the water stable and clear, so that the fish are healthy and less sick, and the fish tank can grow moss and green algae.

Yongqing filter to find out.

There are many types of fish and different diseases, so you want to introduce you to what kind of fish you have. In order to give you an accurate answer, you can also enter Henan Yifei Animal Pharmaceutical Co., Ltd. in the click Technical Services for a more detailed prevention plan, you can also call an expert**.

Raise fish first raise water, the water is good, the fish will be good, and I don't know if you are raising.

The quality of water quality directly affects the health and growth of fish and the utilization rate of feed, so it is necessary to fully understand the characteristics of the pond water environment and strengthen scientific management, and do a good job in water quality regulation around the core issues of aeration and ammonia reduction. The main measures are as follows:

First, remove excess silt from the bottom of the pond

The second is to sprinkle quicklime regularly (when the pH is low).

Thirdly, start the aerator at noon on a sunny day in the high temperature season to improve the dissolved oxygen condition of the pool water.

Fourth, when the water quality is too fertilized, use copper sulfate and other drugs to properly kill some algae, and add new water.

Fifth, in the high temperature season and high-yield ponds, substrate improvers should be applied regularly to improve water quality.

Sixth, use photosynthesis to improve water quality.

First, according to the pond conditions and technical level, a reasonable stocking density should be formulated;

Second, according to the weather, water quality and the growth and activity of the fish, feed regularly and quantitatively to ensure that the fish are well fed;

Third, it is necessary to choose high-quality full-price pellet feed with balanced nutrition to avoid nutritional diseases in the fish;

Fourth, we must strengthen daily management and careful operation, and patrol the pond diligently; Find problems and solve them in time, and do a good job of pond diary;

Fifth, it is necessary to choose excellent varieties with strong disease resistance for breeding.

<>1) Seed quarantine The purchased seedlings should be quarantined.

2) Clear the pond The fish pond should be thoroughly cleaned and disinfected when the fish are released.

3) Fish body disinfection Spring fillet fingerlings are soaked in liquid medicine before entering the pool, which can effectively kill the parasites and bacteria on the body surface and gills of the fish.

4) Manure disinfection; Organic fertilizer should be disinfected before application. Quicklime, bleaching powder, fish kang and other drugs can be used for disinfection.

5) Regular prevention in the high temperature season.

Hanging bags on the feeding table or regularly spraying fungicides during the high temperature season can effectively prevent bacterial fish diseases. The following problems should be paid attention to when using this method: First, the concentration of the drug around the food farm should reach the effective concentration, and it should not affect the feeding of fish.

Second, the effective concentration of medicinal pickpockets around the food market should be maintained for more than 1 hour. the third is that it must be hung continuously or poured for 3 5 days;

In the high temperature season and the peak season of fish growth, regular feeding of bactericidal bait can effectively prevent various bacterial fish diseases;

Change the water quality environment, strengthen scientific management, and do a good job in water quality regulation around the core issue of oxygen enhancement and ammonia reduction.

Do not plant too many plants in the pond, which will cause hypoxia and eutrophication of the water body, establish the fish pond in a shady area, and timely oxygen.

There are many different diseases in the process of fish farming, and the most important thing is to manage the water source, disinfect it regularly, and change the feed.

What are the common diseases of monk fish**.

My newly bought little red fish doesn't eat.

The fish is covered with black spots.

What did my little red fish die of?
