  1. MUNICIPAL SHELLFISH RESTORATION: FORTY YEARS OF EXPERIMENTATION AND PRODUCTION ON CAPE COD, MA. Sandy Macfarlane Coastal Resource Specialists ICSR 2008

  2. CAPE COD, MA • 15 Individual municipalities • Varying shellfish regulations • Each town responsible for • propagation and management within its borders • Tourist-based economy regionally • Most towns have commercial wild, commercial aquaculture and recreational shellfish interests

  3. Towns bought quahaug spawning stock from Cape Cod Bay or contaminated relays from the New Bedford area

  4. Early soft shell clam transplants using a single harrow

  5. Mechanized plowing for clam transplants

  6. Using plowing and netting to try to catch a set of seed clams

  7. A Boston-bound barge entering the Cape Cod Canal ran aground on rocks, spilling 175,000 gallons (700,000 liters) of diesel fuel into the bay (in September 1969).Evidence … suggests theeffects of oil spills could be indefinite. Thirty years after the Massachusetts catastrophe, significant oil residues remain in local salt marsh sediments,according to researchers at the Woods Hole Oceanographic Institution.
