A fish trap is a device designed to catch fish in a specific area, often used in both commercial and recreational fishing. These traps can be made from various materials, such as wood, metal, or plastic, and come in different shapes and sizes. They work by luring fish into a confined space where they cannot escape, making it easier for fishermen to collect them. Fish traps can be found in many cultures around the world, with some traditional designs still in use today. They are often placed in rivers, lakes, or coastal waters, and can be used to target specific species of fish, such as salmon or catfish.
