The optimum propagation temperature is 22-33 ℃, and the optimum water temperature is 28-30 ℃. Mature female shrimps must be unshelled before mating once to mate. Generally, female shrimps ovulate within 24 hours after mating, and then combine with sperm to be fertilized, so that fertilized eggs are orange. After spawning and fertilization, the eggs are hatched with the mother eggs, and the hatching period is 30-31 days when the water temperature is 28-29 ℃. The red swamp crayfish can lay eggs for 2-3 times a year. The survival rate is affected because the eggs and the shrimps can infect bacteria, viruses, parasites and the like on the parent bodies. Therefore, there is a need for ex vivo hatching of the eggs of red crayfish.
