A slide of a map showing sites of the quahog spawner sanctuaries. The quahog
spawner sanctuaries were established to compensate for injuries to shellfish
after oil spilled in Narragansett Bay when the World Prodigy ship grounded in
1989. Quahogs were taken from polluted areas of Narragansett Bay and allowed to
depurate and then moved into clean areas where they were protected from harvest.
