Why do crabs go into cages?

These openings are constructed so that when the crabs enter to eat the bait, they cannot escape, and instead become immediately trapped. Once the crab becomes trapped and cannot leave the same way they entered, they float upward and go through the openings of the inner wire portion, which permanently traps the crab.

How do crab pots catch crab?

This is achieved by careful positioning of the bait and “leads,” which are the sides of the entrance to the pot.

Fishermen use a box-shaped trap called a pot, which consists of a steel frame covered with a nylon mesh. Each pot weighs 600–800 lb (270–360 kg) and a ship may carry 150 to 300 pots. Fish, usually herring or codfish, are placed inside as bait, and then the pot is sunk to the sea floor where the king crabs reside.
