Pacific oyster

The Pacific oyster (*Crassostrea gigas*) is a widely cultivated shellfish known for its mild flavor and meaty texture. Originating from Asia, it has been introduced globally for farming and consumption. These oysters are filter feeders, meaning they filter water to extract nutrients, which helps improve water quality but also makes them sensitive to pollution. They are usually grown on racks or beds in coastal waters and are harvested when reaching market size. Rich in protein, vitamins, and minerals, they are appreciated both as a delicacy and for their ecological role in marine environments.
