For shrimp farmers, releasing shrimp seedlings is a big test. How to manage before and after release?

1. After you get the trial seedlings, you can't rush to promote them. It is definitely not possible to blindly integrate the newly shipped shrimp seedlings into new areas. You'd better try the seedlings first. Seedling trial is to select some shrimp seedlings first, and then change the water in the fish tank to see the living conditions, so that we can choose water for the fish pond. If the shrimps are normal, they can go up and down the pool in one day. If they are not normal, they are not good enough. If such anomalies are resolved, they can be tested again until the shrimps are normal. Shrimp seedlings are not big, and they will be drained if they don't try. If something goes wrong, it will be difficult for you to take them home again, and it will be much more inconvenient to solve the difficulties.

2. The vulnerability of shrimp larvae to water is very high. If water is not suitable for their survival, shrimp larvae will soon have problems and eventually die. Its regulations on water mainly include PH value, dissolved oxygen state and clarity, while in more detail, there are nitrate, permanganate index and other factors that are very easy to cause problems due to concentration values. These are generally professional testing tools, so you can prepare them in advance. The water body is basically up to standard, and prawns will encounter fewer problems in the water.

3. If the preconditions for seedling release are met, seedlings can be prepared in advance. The key in the process of seedling release is the temperature level. If the temperature is not suitable for shrimp seedlings, it is not suitable. Generally, the temperature of continuous high temperature cannot be selected. If the temperature is too high, you can choose the morning, which is not good for everyone to observe the state of shrimp seedlings at night. The temperature should not be lower than 12℃, otherwise it will freeze. Put the container for shrimp fry in the pool for one hour, so that it gradually approaches the temperature of the reservoir, so that the shrimp fry will not notice the change of water temperature when they are released, which is beneficial to their physical and mental health.

4. After checking the seedlings, it doesn't mean that things are over, but it still needs to be checked. This lasts for a long time, usually about 3 days, and shrimp seedlings are most likely to have problems about 3 days before entering the pool. The problems that followed were almost all due to feeding. During the inspection, it is necessary to inspect the pond to see if there are any abnormalities in shrimp seedlings in various areas, such as whether there are shrimp seedlings dead or whether there are shrimp seedlings floating on the river for a long time, so that problems can be dealt with in time. If there are problems, then the promotion of shrimp seedlings is basically very successful.
