The fishery is closed to new entrants in Virginia, now and likely for the next three years. You can transfer under certain cercumstances, such as when someone is getting out of the business. From time to time you see licenses for sale in the trading post and in the paper. The following link on the VRMC web page that has contact info for individuals who want to sell crab licenses. You can post your info there.
