Ostiones

Ostiones is a Spanish word that commonly refers to oysters. It can be used broadly to encompass various species of bivalve mollusks within the family Ostreidae. These marine or brackish water mollusks are characterized by their rough, irregular shells, which are typically asymmetrical and composed of calcium carbonate. Oysters are filter feeders, drawing water into their shells and extracting plankton and other small particles for sustenance.

Commercially, oysters are harvested for both their meat and their shells. Oyster meat is a popular delicacy in many cultures, often consumed raw, steamed, fried, or incorporated into various dishes. The flavor and texture of oyster meat can vary depending on the species, its habitat, and the season. In addition to their culinary uses, oysters play a significant ecological role by filtering large volumes of water, which can improve water quality and clarity.

The cultivation of oysters, known as oyster farming or ostreiculture, is a widespread practice aimed at sustainable harvesting and to meet the global demand. Oyster farming can occur in various environments, from intertidal zones to deeper offshore waters, utilizing different methods such as suspended culture or bottom culture. The pearl industry also involves certain oyster species, though these are typically distinct from those primarily harvested for food. The term "ostiones" in a culinary context almost invariably refers to edible oysters.
