From what I understand you cannot at present
buy a commercial Crabbing license from the state , there is a moratorium on them and has been for many years. You cannot by a commercial from another Crabber either, although there has been talk about that happening. The only way you can get a license is from an immediate family member. Like brother to brother or sister to sister. Dad to son. Not brother inlaw to brother inlaw or sister inlaw to sister inlaw.
I hope this helps
