Hairy crabs generally suffer from crab roe, and there are many reasons for suffering, nothing more than the following:

1, hairy crabs are not yet fully mature. If you eat them too early, the crab roe will be too tender and bitter.

2, the problem of practice, because hairy crabs grow up in water, so there may be some dirty things in them that are not cleaned, which will be very bitter to eat.

3, sick crab, crab yellow is bitter, cream will not be strong. Such crabs are easy to die, some are big, but their weight is not enough. There are some taupe spots or patterns on the shell of sick hairy crabs, which is commonly known as "coccidiosis"-a common disease of crabs. Pay attention to identification when buying.
