How might restaurants begin to help raise baby oysters?

Under a new bill before Maryland lawmakers, restaurants would get a dollar-per-bushel tax credit for recycling oyster shells — a shift that could help restore the region’s oyster beds. Young oysters raised in hatcheries prefer to attach to adult oyster shells, which are in short supply. Each adult shell can host up to 10 young oysters, known as spat, according to the Oyster Recovery Partnership.
