CATDOLL : CATDOLL: What are the methods of disinfection in aquaculture?

1. What are the methods of disinfection in aquaculture?

Generally, quicklime, bleaching powder, flocculants, chlorine-containing and bromine-containing disinfectants and other organic or inorganic compounds are used to improve water quality. However, these methods only treat the symptoms and not the root cause. They can only produce effects in the short term and have adverse effects on aquatic animals. The latest technology developed is a disinfection equipment imported from Denmark. It uses salt and water as raw materials to produce a composite bactericidal solution mainly composed of hypochlorous acid, which can remove biofilm and thus inhibit the proliferation of pathogenic bacteria.

2. Prevention and treatment of jellyfish toxins

When the skin touches the tentacles of jellyfish, there will be a stinging sensation immediately, and linear erythema and papules will gradually appear locally, and the itching will intensify. In severe cases, erythema, wheal, blisters, ecchymosis, epidermal necrosis, etc. may quickly appear locally, and there will be severe pain, chills, diarrhea, nausea and vomiting, chest tightness, irritability, difficulty breathing, coughing, etc. Most jellyfish poisoning is mainly dermatitis or allergic reactions. You can use 5% acetic acid (or vinegar) or 40%~70% isopropyl alcohol wet compresses, and then treat with 1% hydrocortisone. Or use 1% ammonia water to cool the affected area, or use 5% sodium bicarbonate and other weak alkaline solutions or alum water for cold compresses. Use 10 ml of 10% calcium gluconate solution for intravenous injection, or use antihistamines such as phenergan and chlorpheniramine for treatment.

3. How to kill jellyfish in breeding ponds

1. Use a net to catch jellyfish. Since jellyfish are attracted to light like moths, they can be caught at night.

2. Jellyfish cannot adapt to low-salinity water, while shrimp can adapt to slightly lower salt. For example, jellyfish need to eat one pound of salt a day, and they will die if they eat less than nine ounces, while shrimp will not die even if they eat half a pound a day. So you feed eight ounces of salt every day, and the jellyfish will starve to death. In other words, add fresh water to reduce the salinity of the breeding pond and kill the jellyfish. However, you must always observe the performance of the shrimp, and quickly refill the seawater if they feel uncomfortable. In addition, the death of a large number of jellyfish will spoil the water, so change the water in time.

3. Do not let water flow between pools to prevent "infection"

4. What method of sterilization and disinfection is safer in aquaculture?

Aquatic disinfection should be based on the characteristics of aquaculture. When choosing disinfectants, the main considerations are to choose disinfectants that have strong killing power against pathogens, low toxicity and no harm to fish and shrimp, and are easily soluble in water. They are relatively stable and easy to use in the disinfected environment. Commonly used disinfectants include Danish DCW sterilization solution.

5. Can the aquaculture drug Benomyl kill jellyfish?

It depends on the dosage you use. Even if you don't die, it will have an impact.

6. How to use aquatic sterilization

Just dissolve it in water
