Oxygen interruption in the middle of hatching harvest shrimp will lead to hatching failure, because harvest shrimp need high oxygen during the incubation process, and oxygen interruption in the middle will lead to death and cannot hatch.
To avoid this from happening, there are the following workarounds:
1.Ensure oxygen**: During incubation, make sure that the oxygen content in the water is sufficient. This can be achieved through the use of an oxygen pump or inflator.
2.Adjust incubation conditions: If there is not enough oxygen in the water, try adjusting incubation conditions, such as lowering the incubation temperature or increasing the water flow velocity, to reduce oxygen consumption.
3.Regularly check the hatching condition: During the incubation process, regularly check the harvest shrimp in the hatching container to observe their growth and hatching progress. If it is found that the hatching failure of the harvest shrimp, find out the cause in time and deal with it accordingly.
Overall, maintaining adequate oxygen** and keeping a close eye on hatching are key to ensuring successful hatching of harvest shrimp.

There is no need to alleviate it, and the unhatched shrimp eggs cannot be taken out and need to be frozen. Shrimp eggs are frozen under 0, the colder the better. Leave a small portion at room temperature and use it up again.
Shrimp eggs that have just been removed from the refrigerator should be left at room temperature for 24 hours before hatching. If stored in this way, it can be stored for more than 1 year.
It is recommended to freeze shrimp eggs in good years, and if this food is refrigerated, it is easy to spoil. Shrimp eggs should be frozen for a week at -18, and then stored at room temperature for a week.
The dormant eggs produced by the shrimp are very nutritious, and are excellent bait for larvae and adults such as fish, shrimp and crabs.
Harvest shrimp are generally cleaned in conical barrels, first rinsed with fresh water, and then rinsed with seawater. The main purpose of rinsing is to remove debris, egg shells and contamination from surfaces.
In the process of drying, it is necessary to prevent the temperature from being too high, and to pay attention to drying in the sun, not to expose to the sun.
In addition, the storage of this shrimp is also very particular and cannot be placed in the refrigerated layer.

Summary. When hatching harvest shrimp, if there is a lack of oxygen, it is easy to cause diseases such as shrimp seedling oxygenation disease and shrimp seedling dissolution disease, resulting in an increase in the mortality rate of shrimp seedlings. It is necessary to strengthen the aeration of shrimp pond water, replace fresh water in time, appropriately increase oxygen equipment, control the number of shrimp seedlings, and avoid excessive intensive culture.
At the same time, it is necessary to do a good job in the feeding and management of shrimp seedlings to ensure the healthy growth of shrimp seedlings and avoid the occurrence of diseases.
I'm still a little confused, can you be more detailed?
When hatching harvest shrimp, if there is a lack of oxygen, it is easy to cause diseases such as shrimp seedling oxygen holding disease and shrimp seedling dissolution delay disturbance disease, resulting in an increase in the mortality rate of shrimp seedlings. It is necessary to strengthen the aeration of shrimp pond water, replace fresh water in time, appropriately increase oxygen equipment, control the number of shrimp seedlings, and avoid excessive intensive culture. At the same time, it is necessary to do the feeding and bridge management of good shrimp seedlings to ensure the healthy growth of shrimp seedlings and avoid the occurrence of diseases.
Normally, time is not enough, and the shrimp eggs have to hatch 30 in the next year. >>>More
The hatching of crayfish does not need to be heated, and it should be noted that the water temperature of crayfish breeding should be around 24 to 26 degrees, which is conducive to the hatching of fertilized eggs. >>>More
The medical insurance has been interrupted for two years, and the only thing that can be renewed is that during these two years, you can't let the medical insurance reimbursement, and you can be reimbursed after the focus.
The first method: because the color of the 8 wires of the network cable is different, first peel off the rubber skin of the network cable at the broken place, then peel off the skin of the 8 wires in turn, and then screw the copper wire of the corresponding color together, such as green butt green, green and white butt greenish-white. After each wire is connected, it is wrapped with rubber tape. >>>More
