Trap fishing is a method of catching fish using a structure designed to entrap them. These traps can be made from various materials, such as wood, metal, or plastic, and are often placed in water bodies like rivers, lakes, or oceans. The traps are designed to allow fish to enter but make it difficult for them to escape, ensuring a successful catch. This fishing technique is commonly used for species like crabs, lobsters, and fish. Trap fishing is considered a sustainable practice when managed properly, as it can minimize bycatch and reduce the impact on marine ecosystems compared to other fishing methods.
