Oyster sustainability is generally considered favorable due to their ability to filter water and contribute to the health of marine ecosystems. Oysters are filter feeders, which can help improve water quality by removing excess nutrients. However, some oyster populations face challenges due to habitat loss, pollution, and overharvesting. Wild-caught oysters are typically harvested using methods like dredging, tongs, or handpicking, which can have minimal impacts on the environment when properly managed. Oyster farming or aquaculture has become more prevalent as a way to meet demand and relieve pressure on wild populations. Sustainable oyster farming practices focus on responsible hatchery techniques, proper site selection, and careful monitoring to minimize environmental impacts.
