osztrigák

Osztrigák, commonly known as oysters, are saltwater mollusks belonging to the family Ostreidae. These bivalve shellfish are found in coastal waters worldwide, typically in brackish environments where rivers meet the sea. Oysters are filter feeders, drawing water into their shells and straining out plankton and organic matter for nourishment. This filtering process plays a significant role in maintaining water quality in their ecosystems.

Commercially, oysters are harvested for both their meat and their shells. Oyster meat is a delicacy in many cultures, prized for its unique flavor and texture. They are often consumed raw, steamed, or incorporated into various culinary dishes. Beyond their gastronomic appeal, oysters are also cultivated for their potential to produce pearls, although not all oyster species are capable of this. The iridescent nacre, or mother-of-pearl, that lines their shells is also utilized in decorative items and jewelry. Oyster farming, or ostreiculture, is an important industry in many coastal regions, contributing to local economies and providing a sustainable source of food and materials. The life cycle of an oyster involves a free-swimming larval stage before settling on a hard surface, such as rocks, other shells, or artificial substrates, to grow.
