- 2. Facts about the Chesapeake Bay
- 3. It is the largest Estuary in the US Once known as the “Great shellfish Bay”
- 4. An Estuary is a semi-enclosed body of water that has a free connection with the sea
- 5. The bay is shallow Average depth is 21 ft. The deepest spot is near Annapolis MD: 174 feet
- 6. The Bay Provides: Habitats (homes) Food Nursery (juvenile species)
- 7. Bay Organisms The Bay is home to over 3600 living organisms!
- 8. The Bay area is home to over 15,000,000 people! About 50,000 commercial vessels enter the Bay each year
- 9. What about the Oysters?
- 10. Oysters Clean–ed the Bay Oyster REEFS provided a natural filtering system and protected many juvenile species 85% of the reefs are gone
- 11. Think about it! 1 adult oyster filters about 50 gallons of water in 24 hours 19 trillion gallons of water in one week use to be filtered
- 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. 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. 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. It all Begins with AND Supporters
- 16. Oyster Restoration Students participate in Oyster Restoration by monitoring the growth of SPATS CBF helps programs find transfer spots for the adult oysters Students end their project by transferring the oysters to a protected reef
- 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
