Crayfish cage

Crayfish cages are fishing items used to catch crayfish, which, when cooked, heal 200 life points. Cages can be bought for a few coins at the Grand Exchange, at Gerrant's Fishy Business in Port Sarim, or at Hank's Fishing Shop in Lumbridge. Players can also get a crayfish cage for free once from Hank. They do not require bait, and may also be stored in the tool belt.

Crayfish cages can be used in Dragon Slayer when trying to get the map piece in the Dwarven Mines, as it is a small crustacean cage.

Where to use
Crayfish cages can be used wherever there is a fishing spot with the "Cage" spot available. There are quite a few of these in the free-to-play world.
