Crabs will lay around 10-15 days, depending on the sires when cultivated. For crabs weighing 150 grams already have eggs in it.
Crab Crabs
With a period of about 5-10 days, the crab can already be fat and contains when maintenance is good. For technical enclosure is the same as other crab cultivation, If the fattening process has been successful for female crabs then it can be used for the cultivation of crabs laying eggs. Remove from the male and female keipting fights so that all goes well and the harvest is successful.
