I don't know that area too well we were tourists ourselves. but the Maine State Aquarium idea is good. another idea I thought came from camping near French Canadians as a child. they knew everything about what to eat on the coast, like mussels, snails , sea urchins etc. and did, and invited us gor dinner. they ate all this before it was trendy. call an aquarium in nova Scotia.
You can ask people at the aquarium but marine resources can send you materials that can help you
