There were plenty of clams shelled out on Saturday afternoon at Nancy’s Snack Bar in Oak Bluffs, and all for a good cause. It was the fifth annual quahaug and oyster shucking contest, and this year the cause was the Animal Shelter of Martha’s Vineyard, which collected a lot of clams — $1,000 to be exact.
