A new study from Cornell University provides the first genetic evidence that farmed eastern oysters are mixing with and potentially boosting wild oyster populations in New York's Long Island Sound. - Researchers analyzed genomes of wild oysters from the Hudson River, East River, and Long Island Sound, finding genetic markers of farmed oysters in the latter two areas.
- Oyster farms may provide a demographic supplement to wild populations, as larvae can travel kilometers before settling. - Oysters filter water, remove pollutants, and support aquatic life, making their revival beneficial for estuary health.
The study suggests that oyster aquaculture, unlike some other forms of fish farming, can offer ecosystem services without harming the environment.
