Generally, the black shell shrimp can breed in 2-3 months. Some precocious individuals may be bred for more than one month. They can only reproduce when they grow to more than 1.5 cm. However, in actual culture, it is more recommended to use individuals with body length of more than 2 cm as parent shrimps for reproduction. Because it can produce better quality shrimp larvae.
After the black shell shrimp incubates the eggs, after about 15-20 days, the shrimp eggs can hatch out of the shrimp. The specific time of incubation is closely related to the water temperature. If the water temperature is about 26 C, the incubation time is about 13-14 days. If the water temperature is between 22-24 C, the incubation time is about 15-16 days. If the water temperature is low, the shrimp eggs will take about 20 days to hatch.
The black shell shrimp kicked eggs refers to the behavior that the mother shrimp kicks off the eggs in the abdomen and stops hatching when it is in spawning. There are two main reasons for this phenomenon, one is that the mother shrimp was frightened, and the other is that the water quality suddenly changed greatly. Therefore, when the mother shrimp holds eggs, attention should be paid to maintaining water quality, and attention should be paid not to suddenly change the light conditions, in order to avoid the mother shrimp kicking eggs.
