The production time for the average ornamental shrimp to hold eggs and give birth to baby shrimp is between 20 and 30 days. When shrimp holding eggs, you need to isolate the female shrimp to avoid the lower body of the baby shrimp being eaten. Incubation Fertilized eggs are incubated on the body of the female shrimp, so the fertilized green shrimp is also known as egg-holding shrimp. It takes about 20 days for the shrimp larvae to hatch when the water temperature is around 25°C. If the female shrimp dies before the eggs hatch, the shrimp eggs can be removed for artificial incubation. Temperature control at 26-28℃ during the period can increase the speed of hatching.

Embryonic development

The fertilized eggs of the red crayfish are dark yellow, and gradually change to yellow-orange, red-orange, and light gray as the embryo develops. Will hold eggs shrimp divided into four groups for the embryonic development of comparative tests found that: in 19 ℃ under the conditions of the red crayfish eggs embryonic development is extremely slow; in 21 ~ 23 ℃, hatching out of the membrane time of 41 days, 80 days of juvenile shrimp from the mother; 26 ℃ fertilized eggs 30 days hatching out of the membrane, 52 days of juvenile shrimp out of the mother; 29 ~ 30 ℃, 25 days of incubation out of the membrane, 40 days out of the mother.
