Prevention and treatment of crab molting disorder

Symptoms of crab molting disorder

Crabs suffer from molting disorders when they are sick or lack of certain trace elements. Crabs are unable to shed their shells or can only shed part of their shells. There are cracks in the head, chest and abdomen, blackening all over the body, and finally death.

Prevention and treatment of crab molting disorder

Check whether the crab is sick, and if it is already sick, it should be treated according to the case; or crush the crab shell (poultry eggshell can also be) and mix it into the feed; or sprinkle the whole pool with lime water (the concentration of lime in the pond water is 15~20mg/kg), once every 5 days, 3 times 4 times in a row.
