Midyeler, or mussels, are bivalve mollusks found in both saltwater and freshwater environments. They have a two-part shell that is usually dark blue or black and can be found attached to rocks, piers, or other surfaces. Midyeler are filter feeders, meaning they obtain their food by filtering plankton and other small particles from the water. In many cultures, midyeler are considered a delicacy and are often prepared in various dishes, such as mussel stew or served with pasta. They are rich in protein, vitamins, and minerals, making them a nutritious seafood option. Sustainable harvesting practices are important to ensure their populations remain healthy.
