How Do Shrimp Egg Works

The abundant artemia eggs are also known as brine shrimp. They are widely regarded as an important biological food. It has strong adaptability to bad environment and has good reproductive ability. The insect larvae of the year are highly nourishment, so the abundant eggs are excellent food feeds for fish, shrimp and crabs. After hatching, the collection of prawns can be collected using the plankton net (more than 60 mesh). If the plankton net is not available, it can be used to buy the screen for the silk screen to collect the prawns.

1. The artemia egg can be preserved in the dry condition for a long time. When the salt is 20~30, the temperature is 25~27 degrees centigrade, and the amount of oxygen needed for the incubation is satisfied. After 24~48 hours, the larvae are hatched. The grasp of time is the most critical. We must pay attention to these conditions: time, temperature and salinity.

2.When the artemia egg is hatched, the impurities and sediment on the egg can be washed away with glycerin, and the clean eggs are obtained. The egg can also be frozen from -3 C to -15 C, and then be incubated after 1~3 months of cold storage, and the hatching rate of 60% to 90% can be obtained. This ensures the survival rate and productivity of hatching.

3.The winter eggs (or after being sterilized and shelled) are put into the sea water directly. The water temperature is kept at 28-29 degrees C and can be developed into a naupli after 24 - 30 hours of direct ooootion. A small bulb can be placed on the side of the incubator to attract the aggregation of the larvae so as to achieve a better separation effect. The longer the time is, the better the separation effect is, the better the separation effect is, but it will lead to the death of the newly hatched prawns because of the hypoxia. Generally speaking, it is appropriate to be between half an hour and an hour, but it will change with the degree of hatching of the shrimp eggs.

Shrimp egg incubator

The improved method: the shrimp eggs were put into the bag made of sifted silk after being sterilized and fully soaked. They were placed in the oochemical chamber at 25 degrees C, avoiding strong light irradiation and ensuring adequate oxygen supply. After 8-9 hours, the larvae became the larvae of lanterns (the eggs were not separated from the young and lantern shaped), and then they were put into the sea water at 28-29 degrees centigrade to become a nauplite.
