A Detailed Guide to Key Management Points for Whiteleg Shrimp During the Seedling Stage

Whiteleg shrimp, also known as Pacific white 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 management points for whiteleg shrimp during the seedling stage? Let's find out together!

1. Pond bottom

Generally, after the shrimp seedlings are released, they will gather at the pond bottom. The pond bottom is where the shrimp seedlings are most active and also where they rest. When farming whiteleg shrimp, you should do a good job of maintaining the pond bottom before releasing the seedlings, creating a good growing environment for them. Remove the sludge at the pond bottom thoroughly, and also remove harmful substances such as garbage in a timely manner. Then drain the water and expose the pond to the sun. Spread quicklime over the entire pond for disinfection, eliminating parasites and pathogens. The early growth of shrimp seedlings is very important. If the living environment is not managed well, the mortality rate of the shrimp seedlings will increase significantly, causing unnecessary losses.

2. Feeding

Shrimp seedlings are at a very fragile stage and also have the greatest demand for nutrients. When farming whiteleg shrimp, the feed should be changed according to different environments. Try to avoid feeding opening feed right from the start. First observe the body, activity and other conditions of the shrimp seedlings. Once the shrimp seedlings have fully adapted to the farming environment, start feeding them. When the shrimp seedlings grow to one month old, they will reach a growth critical point. According to the growth condition, body size and other aspects of the shrimp seedlings, appropriately change the feeding method and type of feed.

3. Water quality

Water quality is the most basic and also the most important condition for the growth of shrimp seedlings. Before releasing the shrimp seedlings, not only should the farming pond be disinfected, but the farming water body should also be disinfected to prevent parasites and pathogens from breeding due to poor water quality and lowering the survival rate of the shrimp seedlings. After the water body is disinfected and the pond bottom is cleared of sludge, the shrimp seedlings gradually adapt to the farming environment, their food intake begins to increase, and their growth speed accelerates. This increases the microorganisms in the water, leading to a decrease in dissolved oxygen in the water and causing water quality to deteriorate. Therefore, during the farming process, close attention should be paid to changes in water quality, water disinfection should be done well, and water should be changed at the appropriate time to ensure the water body is always in a clean and fresh state and that the shrimp seedlings can grow normally.

4. Water conditioning

Water conditioning is also a very important task when cultivating shrimp seedlings. Many people do not have a correct method for water conditioning and usually just adjust it randomly, which means that when problems appear in the water body, they cannot identify the source of the problem in time or take corresponding measures. Whiteleg shrimp is a shrimp species tolerant of low salinity, and it can effectively regulate the osmotic pressure of the water body itself. After disinfecting the water body, add a small amount of beneficial bacteria to the water to make fine adjustments to the water environment, which can effectively improve the survival rate of the shrimp seedlings. However, if the salinity in the water is too low, it is also unfavorable for the growth of the shrimp seedlings, will increase the mortality rate of the shrimp seedlings, and make the shells of live shrimp seedlings soft. At this time, a small amount of salt should be added to neutralize it.

The above are the key management points for whiteleg shrimp during the seedling stage. I hope they can help you!
