he might be able to get a recreational crabbing license that allows him to catch 1 bushel per day(may be 2 not sure about rec, lic.) but technically he is not allowed to sell them, it is for personal use only. Another way is to find someone who wants to sell their license, which could cost some big bucks. Or if you know someone that has a commercial license that they are not using you might be able to get them to sign it over to him for the summer, but them you have to fill out all the reports every month. DNR is not issueing any new commercial crabbing licenses at this present time. My husband is a commercial waterman, got this info from him
