This process can be achieved through various techniques, including sun drying, air drying, or using dehydrators. Dried fish is commonly used in many cuisines around the world, providing a long-lasting source of protein. In addition to its preservation benefits, dried fish is often rich in nutrients, including omega-3 fatty acids and vitamins. It can be enjoyed as a snack, added to soups, or used in various dishes. Popular varieties of dried fish include cod, herring, and anchovies.
