Fish farmers work to restore the San Francisco Bay
The loss of oyster reefs in the bay has affected its entire ecosystem. Oysters are natural filter feeders, filtering out small sediments and contaminants in the water. The unclean water has made it difficult for underwater grass to grow, reducing habitats for fish. The California Shellfish Initiative … works to advance local restoration plans for the bay, partnering with the California Coastal Conservancy to rebuild its native oyster reefs and wetlands.
