Did you know that oysters, simply by eating, filter the water they live in? An adult oyster can filter up to 225 L of water every day! In addition, oyster reefs play the important role of sheltering many fish and crab species. Today, the Chesapeake Bay’s oyster population is dangerously low—down to only a few percent of its historic level. To improve the overall health of the bay, we need to restore the water-purifying, habitat-providing, marine animals. As an Oyster Restoration and Fisheries Scientist with the Chesapeake Bay Foundation (CBF), Stephanie Reynolds supports this important ecological resource.
