Before when fishing I've seen people using dapping rods off of rocks and with the use of polaroids hang a shrimp over fish until it takes,jerking it up and down tantalisingly until it takes.Worm can also be used.A lot of other fishermen though frown upon it as it can be successful when all else fails.They thought it wasnt giving the fish a fair chance and was bullying it into take.I've never tried it myself and am undecided.What do other fishermen think??
