A lobster trap (British English: lobster pot) is an effective way for fishermen to catch many lobsters at once when lobster fishing. The trap usually consists of a wooden frame surrounded by a rope mesh. A piece of bait, often fish, is placed inside the trap. The entrances to the traps are designed to be one-way entrances only. The traps are checked every other day by the fisherman and rebaited if necessary. One study indicated that lobster traps are very inefficient and that most all lobsters walk right out of them.
