What medicine to use to catch lobsters Shrimp don t die just dizzy?

In this case, you can use those Moutai wine, if you catch lobsters, the shrimp will not die, but will only be dizzy, and the effect is very good.

It is better not to use drugs and pollute water sources.

The pesticide "kills" a small box, diluted to 50 liters with water, and then sprayed on the edge of the pond or river, which can be about seven or eight acres. After about half an hour, you can catch a large number of shrimp floating on the shore. If the shrimp wants to live, put the shrimp immediately into the living water flow place to raise, about eighty percent of them will survive.

1. Shrimp is a kind of arthropod that lives in water, belonging to arthropod crustaceans, and there are many types.

2. By the curvature of the abdomen and tail, it can quickly swim backwards. Eat tiny creatures, some eat carrion.

3. Freshwater shrimp is warm and sweet, slightly warm, and enters the liver and kidney meridians. Shrimp meat has the effects of tonifying the kidney and strengthening yang, clearing milk and anti-toxin, nourishing blood and solidifying essence, dissolving stasis and detoxifying, nourishing qi and nourishing yang, relieving pain, appetizing and dissolving phlegm.

It works well with inulin, depending on whether you are in a small area or a large area. A small range of small bottles are packed in glass bottles, and if you want to use medicine for a certain section of the whole river, you must buy a large bottle. If the water is flowing, it is better to mix the medicine with sand first, and then sprinkle the medicine in the upper reaches of the river and sprinkle it in the middle of the river.

In this way, the medicine can sink to the bottom with the sand, and the effect is obvious. Generally, after half an hour of medication, the shrimp will swim to the bank of the river, which can last for about 3 hours. Find a few more people to arrest.

If you catch it, you can wake up by putting it in clean water immediately.

I've done it a few times before, and the most time I made forty or fifty pounds. Now we have very few shrimp in this river, I don't know where you are?

If there is a boat in the river, the shrimp that swim to the shore will be scattered by the waves, so choose the time when there are few boats.

Don't use it in the fish pond, the fish will die!!

Lobsters can be killed with pesticides that have less effect on other organisms, such as deltamethrin (commonly known as dichloride).

During the experiment, it was found that crayfish are very sensitive to enemy killing, and under laboratory conditions, when the concentration reaches 2 milligrams per liter, all crayfish are killed within 24 hours, while fish such as eels, snails, and loaches do not appear abnormal. When the dosage per mu is 400 milligrams, the crayfish will basically be killed, but for a relatively longer time, but it will not affect other organisms in the terraces. If the concentration reaches 500 mg per mu, although it can kill crayfish for a short time, other organisms will also die in small quantities, and from the safest point of view, the optimal concentration is 400 mg per mu.

Deltamethrin (molecular formula C22H19BR2NO3, the formula is a white oblique guideline crystal, melting point 101 102, boiling point 300. It is almost insoluble in water at room temperature and soluble in a variety of organic solvents. It is more stable to light and air.

It is more stable in acidic media and unstable in alkaline media.

Quickly kill lobsters can use pesticides such as deltamethrin, organophosphorus, cyanofluoxate, oxatrione, etc., such as deltamethrin, this pesticide is a kind of pyrethroid insecticide with high toxicity, with the effect of contact killing, stomach poisoning, rapid contact killing effect, strong knockdown power, effective period of up to 7-12 days, while killing lobsters, the impact on other organisms is small, and it is necessary to pay attention to the use of low temperature when using better. However, there is no guarantee that it will not affect the creatures in the fields or ponds. It is recommended to use the capture method to be better.

Crayfish disease, unexplained death, this is a headache for many farmers, some people use a lot of medicine after the more they die, some people use a little medicine on it. In fact, there is a certain pattern in the onset of lobsters: in early May, large lobsters begin to die, and slowly after the water quality deteriorates, crayfish begin to die again.

After picking up the lobster, it was found that 70% of the dead cephalothorax had formed a layer of soft red shell, and there was a black carapace ulceration on the body, mainly due to nutritional deficiencies and bacterial infection. Treatment method: first use Teli calcium + enzymatic hydrolyzed polysaccharide (1 + 2 with 4 mu) to supplement nutrition to promote hulling, and then use Bioanwei + nano oxygen (2 + 1 with 4 mu, the situation is serious with Baianwei to mu).

On the 3rd day, it basically improved, and after that, we must pay attention to detoxification and cultivation of algae, and at the same time, we must keep up with the internal administration, so as to break the roots.

The new concept of "conservation" is to pay attention to the pond breeding environment and the healthy maintenance of the microecological environment in the breeding object on the basis of the scientific concept of "prevention first, prevention is more important than cure". Its main content is to take stable and healthy dissolved oxygen in the water body as the core, cultivate and maintain good algal phase, good water quality and good substrate; Maintain the healthy liver, intestines, stomach and gills of the breeding object, and promote the healthy circulation of the microecology in the breeding object, so as to achieve the goal of sustainable development of ecology, health and efficient breeding.

You have to go up to the picture, otherwise how will others know.

Summary. Hello, crayfish are flexible and like to hide in stone crevices or aquatic plants, which is especially difficult to catch. However, the pesticide and water are diluted and shaken into milky white, and the crayfish will be stunned because of lack of oxygen after about half an hour, so that the crayfish can be fished up without much effort, and dozens of catties can be caught in one night, with low cost and high efficiency.

The poisoned crayfish are slowly brought back to life in the clear water, flow into the market, and finally be eaten by us crayfish lovers. However, the pesticides that remained in the crayfish tissue and meat were also eaten by us. Food safety incidents occur frequently.

You answer well, crayfish move flexibly, like to hide in stone crevices or aquatic plants, especially difficult to catch. However, the pesticide and water are diluted and shaken into milky white, and the crayfish will be poisoned because of lack of oxygen after about half an hour, so that the crayfish can be fished up without much effort, and dozens of sleepy catties can be caught in one night, with low cost and high efficiency. The poisoned crayfish are slowly brought back to life in the clear water, flow into the market, and finally be eaten by us crayfish lovers.

However, the pesticides that remained in the crayfish tissue and meat were also eaten by us. There are many food safety incidents.

Please refrain from eating such lobsters as this may cause harm to your body.
