| Definition |
A tool, pipe, cable, rod, packer, or other piece of equipment that has fallen to the bottom of the well or is stuck in the well. Lost roller cones followed by failed tool joints and drill pipe are the most common fish. The fish must be removed out of the well before drilling can resume. A fishing string with fishing tools is used to remove the fish.

| Context |
On a simple fishing job, the string is lowered to about two or three feet from the fish, and then fluid is circulated to clean around the overshot. The string is then rotated to the right, and the overshot is lowered over the fish. When a weight reduction is noted on the string, rotation is stopped and some weight is set down on the fish. When the fish is tagged, the grapple sets. If when the string is pulled up the weight on the string is equal to the original weight, the fish is caught.
