What to do if there are water lice in the fish tank?

Water lice are most afraid of salt water, and immediately leave the surface of the fish when they encounter salt water.

Treatment: Use 1% salt water, water lice are most afraid of salt water, and leave the body surface of the fish immediately when they encounter salt water. Then the diseased fish is removed and examined. For fish ponds where a large number of fish lice occur, all the diseased fish are fished out and put into the crystal trichlorfon.

Soak the fish body in the liquid for 2-5 minutes. Both the fish body and the fish lice are anesthetized.

phenomenon, the fish lice quickly fall off, and then put the fish in clean water, and soon return to normal.

Clean the tank completely, and then change the water regularly, normally once a week. When changing the water, try to absorb the garbage from the bottom as much as possible. Also, don't feed too much when feeding the fish, if you can't eat too much bait, it is easy to breed insects.

How big is a fish tank??? Need to change two or three basins with so much water???

It is recommended to change the water completely.

Do a good job of disinfection before changing the water.

Clean up the aquatic weeds carefully.

The sand and gravel are disinfected with boiling water.

Take care to protect the fish when changing the water.

Prevent death due to drastic temperature changes.

If you don't change the water.

Clean the screws manually.

Pick out all the snails.

When the snail sees it, he fishes it.

Put some ratfish.

Enhanced filtration. Change the filter frequently.

Suspend feeding. I don't know what the larvae of water lice are.

If the water is too fat, it may be a protein worm.

Stop feeding. Fish may go to eat bugs.

Shrimp pond water lice generally use quicklime to purify water quality, with a dosage of 12-15 kg per mu per meter of water depth. It can also be used with bleaching powder, EM bacteria, nitrifying bacteria, fishery special water purification agent, etc.

Let's take a look at the shrimp farming method:

Aquaculture water source requirements (1) seawater for aquaculture. The seawater is precipitated and purified to meet the NY5052 standard. (2) Shallow underground water for aquaculture.

Because groundwater resources are different in different places, they are treated differently. A shallow well is dug along the coast to match the corresponding area of cultivation. The data standard for water is salinity 1%, water temperature 17, pH value, in line with NY5051 standard.

3) Aquaculture water ratio and disinfection. Seawater and fresh water are mixed in proportion, the salinity is about 20, bleach powder or chlorine dioxide can be put into disinfection, and a week later, the composite beneficial bacteria culture water can be added.

Selection of shrimp seed and stocking method (1) Shrimp seed. Shrimp seedlings from regular manufacturers should be purchased to ensure that they are disease-free shrimp seedlings. The samples cultivated by the manufacturer, the water and temperature indicators are normal, and the body length of the shrimp is about 1cm or more, and the seedlings can be put into cultivation.

2) Seed density. The first seedling release period in the north is in early April, the water temperature is 22, and the number of shrimp seedlings is controlled at 300 m2. The second seedling release period is generally in August, and the temperature is generally higher in August, so the density is slightly reduced, and it is controlled below 225 m2.

Aquaculture water quality (1) stocking management. The water depth of shrimp seedlings stocking is about 1m, and the pond water is slowly adjusted after one week of stocking, mainly by adding. The method is to flush and add 5 to 10cm of water per day.

When the water level reaches its peak, the sewage should be discharged and recharged, and the exchange of sewage accounts for about 10% of the pool water. 2) Water quality indicators. The number of water quality indicators such as temperature, salinity, pH, nitrite and dissolved oxygen is strictly controlled every day.

Because of the breeding process will encounter a variety of problems, the pool should pay attention to whether there is a high content of organic matter in the pool or weather problems, if the former should pay attention to the amount of water exchange, the daily water change is not less than 30% of the pool water, and control the amount of feed.

Summary. If you find that there are fish lice on the body of a very small number of fish, you can directly remove them with metal tweezers, and you can apply purple potion if there is a wound or bleeding. If the fish is infected in large quantities, the diseased fish should be fished out, soaked in an insecticide for about 10 minutes, and then put back into the fish tank after it has been removed.

Pay attention to the details and let the water change after not infecting other fish.

In the fish pond, all the fish are there, how can the bottom be removed.

Fishpond. Is it a lot.

If it is determined that it is a fish.

In the case of bai lice, a medicated bath with 3% salt water will do. It turns out that the water in the zhiyudao tank must be thorough.

Bottom exchanged. Fish lice.

As soon as it encounters salt water, it will fall off the fish, soak it in salt water for about 20 minutes, and then remove the fish and put it in new water to raise. This fresh water must be exposed to the sun for at least 2 days to kill bacteria and parasites. If the fish lice injure the fish, apply the wound with red tribute or purple potion.

The last and most important thing is to find the parasites**. If you keep it outdoors, it is difficult to avoid parasite infection.

Feeding live food is also easy to bring in parasites, as well as aquatic plants, fish feeding water**, etc., depending on how you raise it. Special attention is paid to the problem of water, because water is generally exposed to the sun outside, which may be polluted by outdoor animals and plants. For example, bird droppings containing parasites, rain and rain that wash parasites off leaves into exposed water, etc.

If the procedure is reasonable, the fish lice will soon be gone.

You can shake and feed some traditional Chinese medicine when feeding, such as herbal deworming net, which can kill parasites in 3-5 days.
