1. How much salt should be used per acre to disinfect fish ponds? Is it okay to use salt to disinfect fish ponds?

Generally no salt is used, usually 100 kg of quicklime or 5-10 kg of bleaching powder

I just saw the question from 2014. Brother, listen to the answer given by that guy. I guess all the fish died that time. To disinfect hairtail, the amount of quicklime used per mu should not exceed 20 kg, and the amount of bleaching powder should not exceed 2 kg. In fact, the amount should be reduced.

How many chlorine dioxide effervescent tablets are needed to disinfect hairtail in a 50-mu fish pond? The water depth is about 2 meters.

Too much. What is the concentration of your chlorine dioxide effervescent tablets? How many grams per tablet? I can help you calculate. It is recommended to use aqueous chlorine dioxide.

This depends on the concentration you need and the water quality.

It is best to test whether the chlorine dioxide residue meets the standard after adding it, and adjust the dosage according to the result.

3. What should I do if the refrigerator needs to be disinfected after the new crown?

Yes. You can take the items in the refrigerator of a confirmed COVID-19 patient. The food in the refrigerator has nothing to do with nucleic acid testing and is acceptable. Cooked food is acceptable. The homes of confirmed COVID-19 patients should be fully disinfected.

4. Are hairtail teeth poisonous?

The teeth of the hairtail fish are slightly poisonous. The hairtail fish has a narrow and long head with a pointed snout. The eyes are large and high, the interocular distance is flat, and the center is slightly convex. The mouth is large and straight, and the rear edge of the mouth reaches below the eyes. The lower jaw of the hairtail fish is longer than the upper jaw and protrudes. The teeth are strong, flat and pointed. There are two pairs of large canine teeth with barbs at the front of each jaw. The upper jaw has 10-13 lateral teeth; the lower jaw has 12-14 lateral teeth. They are used to balance the body.

If you accidentally get pricked while washing fish, the reaction will vary depending on your physical condition. Some people will only get red and swollen, while others will get itchy skin. If it is a skin injury, just wash and disinfect it. If the wound is deep, it is recommended to get a tetanus shot and go to the hospital for treatment in time.

Teeth have a small amount of poison, so how can you wash hairtail without getting hurt by your teeth? If you cook it at home, it is recommended to cut off the head and cook it. If you want the dish to look perfect, it is recommended that you wear gloves and use an unused toothbrush to rinse it slowly.
