Shell changing time of hairy crabs

The interval of crab shelling is not fixed. Shell once every two weeks if it is short, and once every two months if it is long.

The interval between two shellings of crabs is related to their development and the suitability of the external environment. If crabs grow well and the external environment is suitable, the interval of shelling will be shorter. If their growth state is not good, or the external environment is too bad, the time interval for them to shell will be longer.

Shelling symptom

(1) If the crab's shell turns yellow and shiny, it means that the crab will shed its skin in 2-3 days.

(2) If the outer shell of the crab is yellow and the inner shell has been formed, it means that the crab is about to shed its skin.

(3) If the temperature is normal, the crab's food intake suddenly drops, indicating that the crab is going to shed its skin.

(4) If the crab moves on the grass or near the water at night and looks for a shelter, it means that the crab is going to shed its shell.
