Crustacean traps are specialized devices used to catch various types of crustaceans, such as crabs, lobsters, and shrimp. These traps are designed to attract crustaceans using bait, often made from fish or other seafood. Once the crustaceans enter the trap, they find it difficult to escape due to the trap's structure, which typically includes one or more entry points that close behind them. These traps come in different shapes and sizes, depending on the type of crustacean being targeted and the fishing environment. Fishermen often use multiple traps at once, strategically placing them in areas where crustaceans are known to gather. This method of fishing is not only effective but also helps manage crustacean populations sustainably.
