Chesapeake Bay: Oyster gardening helps improve quality of local waterways

Lifestyle and LeisureHealthGardeningPetsScienceChesapeake Bay FoundationSaluda

Did you know these stats about oysters and oyster gardening?

  • Adult oysters filter up to 50 gallons of water a day, removing algae and sediment that negatively affect waterways.
  • Oyster reefs provide habitats for more than 300 different plants and animals in the Chesapeake Bay.
  • Volunteers in the Chesapeake Bay Foundation's oyster gardening program grow approximately 300,000 oysters per year for restoration.
  • The three-dimensional nature of oyster reefs vastly increases the surface area available to not only oysters but other plants and animals that depend on hard substrate for all or part of their life cycle.
  • Oyster gardening accelerates the growth rate of oysters better than raising the marine mollusks in their natural environment. This is important because the larger the oysters, the more eggs they produce -- a 3-inch female can produce 30 million eggs; a 3.5-inch oyster can produce twice as many.
  • Oyster gardening heps restore oyster populations in the waterways in which they are grown because they spawn before the foundation collects and transplants them onto a sanctuary reef.

Learn where you can drop off oyster shells for reef restoration at http://www.cbf.org/page.aspx?pid=1456.

Your shells are used as homes for baby oysters; recycled shells are placed in tanks of water with oyster larvae swimming and attaching to the shells; after a few days, the spat-on-shell is used to build a new oyster bar, according to the Chesapeake Bay Foudation's website.
