Taken from “Tips & Tricks to catch more fish” by Tony Bishop. Got it from the library:
(I took a photograph of the book, which has a diagram, but I couldn’t upload it. Does anyone know why? It simply says “Could not upload attachment to [document])
“The most efficient method I know for catching crabs is to hold of some stockings or pantyhose. Put some sand or a sinker in the toe of the pantyhose and tie a half-hitch just above the toe, then place a piece of bait in the stocking. Tie this onto the end of a line and drop it to the bottom. Crabs trying to get at the bait get entangled in the stocking.
This method works well when surfcasting. Put a bait and a sinker in the socking foot, tie it off to the end of your line and fire it out. Then slowly reel it in, pausing often”
