When did the crab shell? What are the signs?

Actually, this date is still uncertain. Crabs are crustaceans, so their shells are peeled according to their physical development. In other words, some crabs are very nutritious, and they should be peeled once every two weeks, and some may take two months ~ and they will not be peeled if they hibernate.

Three or four hours before the shell of shrimp and crab is shelled, the color of the shell will become dim, and the eyes will become foggy, as if covered with a film. This is a sign before shells are shelled. Generally, shrimps and crabs will look for sheltered areas to hide in the process of hatching, such as cracks in stones and aquatic plants. Shrimp and crab will have a strong smell when they shell, which will attract other shrimp and crab to attack for food.
