Native oysters are bivalve mollusks found in coastal waters, particularly in estuaries and bays. They play a crucial role in marine ecosystems by filtering water, which helps maintain water quality. The most common species in the United States is the Eastern oyster (Crassostrea virginica), known for its distinctive, irregular shell. These oysters are not only important ecologically but also economically. They are harvested for food and are a popular delicacy in many regions. Sustainable farming practices are being promoted to ensure the health of native oyster populations and their habitats, benefiting both the environment and local communities.
