  4. 4. An Estuary is a semi-enclosed body of water that has a free connection with the sea
  5. 5. The bay is shallowAverage depth is 21 ft. The deepestspot is near Annapolis MD: 174 feet
  6. 6. The Bay Provides: Habitats (homes) FoodNursery (juvenile species)
  7. 7. Bay OrganismsThe Bay is home to over 3600 living organisms!
  8. 8. The Bay area is home to over 15,000,000 people!About 50,000 commercial vessels enter the Bay each year
  9. 9. What about the Oysters?
  10. 10. Oysters Clean–ed the Bay Oyster REEFS provided a natural filtering system and protected many juvenile species85% of the reefs are gone
  11. 11. Think about it!1 adult oyster filters about 50 gallons of water in 24 hours19 trillion gallons of water in one week use to be filtered
  12. 12. What Happened? By the 2nd half of the By the 1920s, 20th century, the dredging removed remaining reefs ¾ of our oyster were destroyed reefs by disease, overharvesting and pollution
  13. 13. So Why Collect Shells? SPATS (Babies) Baby oysters grow on existing oyster shells! Existing oyster shells are not easy to get and are not free
  14. 14. Oyster Growth in a ‘Shell’ Spats are grown in  Now they grow into adult various research labs oysters and if lucky, (VIMS) or by non- reproduce with other profits existing adult oysters Vilegers (swimming stage of the oyster) ‘sense’ a protein that allows them to recognize an existing shell Once they receive a signal, they begin their voyage towards it and attach for life
  15. 15. It all Begins with AND Supporters
  16. 16. Oyster RestorationStudents participate inOyster Restoration bymonitoring the growthof SPATSCBF helps programsfind transfer spots forthe adult oystersStudents end theirproject by transferringthe oysters to aprotected reef
  17. 17. Without Shells Without shells, programs to grow  Without shells, our oysters will not Bay will not survive continue  Without shells Without shells, oyster millions of other reefs will continue to species that rely on disappear oysters will die
