What are the key points for disease prevention in Pacific white shrimp

The Pacific white shrimp, also known as the whiteleg shrimp, has an average lifespan of more than 32 months and a high yield per unit, making it very popular among farmers. So, what are the key points for disease prevention in Pacific white shrimp farming? Let's find out together!

1. Choosing the environment

Choosing a good farming environment is the primary factor in preventing disease. The farming area should be chosen in a place with abundant water sources, clean water quality, shelter from the wind and facing the sun, quiet and free from noise, far from urban areas, and far from traffic routes. Determine the area of the farming pond according to the farming quantity, or the reverse is also possible, but the surroundings need to be equipped with a reservoir and a disinfection pond equal in area to the farming pond. The shrimp pond must also have a good drainage system to facilitate later water changes and disinfection, and oxygen supply equipment must be prepared to prevent insufficient dissolved oxygen in the water.

2. Clearing silt and cleaning the pond

First, the silt in the shrimp pond should be cleared according to the characteristics of the four seasons, because after a period of rearing, a large amount of silt accumulates at the bottom of the pond. Silt is the favorite environment for bacteria, and if this silt and these bacteria are not dealt with in time, the water quality in the shrimp pond will deteriorate. Water quality is the basic condition for the survival of white shrimp, and when water quality deteriorates, the growth environment of white shrimp is greatly affected, making them prone to disease. Therefore, choose a reasonable time according to the changes of the four seasons to carry out a thorough pond-cleaning of the shrimp pond, clearing all the silt and bacteria at the bottom of the pond, and improving the living environment of the shrimp.

3. Stocking density

In many cases, large-scale disease outbreaks in white shrimp are caused by overstocking. Reasonably control the stocking density. In order to better control the stocking density, avoid excessive concentration of farming, and reduce contact among white shrimp and the spread of pathogens, the white shrimp population should be reared in batches. The common farming method now is to place a certain number of mesh grids in the shrimp pond and put the white shrimp population into the grids in batches for separate rearing. This not only allows timely discovery and handling of diseased shrimp, avoiding disease caused by infectious diseases, but also allows better control and management.

4. Grasping the growth situation

During the farming process, a schedule for inspection and examination should be drawn up, with regular inspections every day to check for abnormal conditions. During each inspection, examine some of the white shrimp and analyze their condition. If diseased shrimp are found, roughly determine the disease based on their growth state and symptoms, and promptly apply the right treatment according to the disease. Examine all the white shrimp, isolate all the diseased shrimp, dissect the dead and diseased shrimp to find the cause of the disease, and then take corresponding prevention and control measures for the remaining white shrimp, improving the prevention and control capacity for white shrimp and reducing the mortality rate caused by disease.

The above are the key points for disease prevention in Pacific white shrimp farming. Have you learned them all?
