Oysters are natural filter feeders. A single oyster filters up to 50 liters of water every day. This means that they feed by pumping water through their gills, trapping food particles, nutrients, suspended sediments and other contaminants. In addition, oysters help keep the water clean and clear for underwater grasses and other aquatic life.
Oysters are multi-talented marine warriors with an impressive bag of tricks behind their calcareous sleeves. Their filter feed improves water quality and nutrient cycling. They provide a safe haven for young fish and small invertebrates, reduce coastal erosion and even absorb carbon.
