What are the administration methods for preventing and treating prawn breeding diseases?

The administration methods for preventing and treating prawn breeding diseases include splashing, hanging, bathing and oral administration. According to the condition of shrimp disease, breeding varieties, feeding methods and application purposes, different medication methods are selected.

(1) splash method

The whole pond spraying method is the most commonly used method to control shrimp diseases. It takes the water body of the whole pond as the application object, selects the appropriate pesticide concentration to calculate the dosage on the premise of correctly calculating the water quantity, and then dilutes the weighed drugs with water and evenly scatters them on the water body of the whole pond, thus achieving the purpose of preventing and treating shrimp diseases. (2) Hanging method

Also known as hanging basket (bag) method. That is, the medicine is put in a container or cloth bag with micropores, hung around food or where shrimps often appear, and the purpose of administration is achieved by using the feeding habits of shrimps in the food field. At present, the commonly used suspension drugs are chlorine-containing disinfectants, and the dosage of the drugs depends on the specific drugs. (3) Immersion bath method

An important way of administration in aquaculture. According to the size of immersion bath water, it can be divided into full shower method and immersion bath method; According to the different concentration and time of drug immersion bath, it can be divided into instant immersion bath, short immersion bath, long immersion bath and running water immersion bath. (4) Oral administration

Also known as oral administration, it is a commonly used medication method in intensive shrimp ponds. When in use, the dosage of the medicine is added into the powder according to a certain proportion of the feed, and the medicine bait is made for feeding. Dose calculation: oral dose (g) = shrimp quantity in shrimp pond (kg) × shrimp dose (g/kg body weight); Bait concentration (%) = dosage/(shrimp load × daily feeding rate) × 100%.
