Shelfishing License Question

[Rmarsh]

I got a non-resident shellfishing license (Dartmouth MA) and went quahoging for the first time.
Did pretty well but now have some questions that I could not find answers to in the regulations they gave to me.
I could call the town hall and ask for some clarifications, I know, but I would like to hear from others with more experience have to say.
My wife would like to go on her days off, but the license is in my name, do I have to be present, or is it a family or household permit?.
Likewise, can we as a family all gather quohogs working as a team.
I know with a fishing license it is each individual, but what about shellfishing?

Thanks
