hook the crabs thru the edge of the shell or the butt or tie it in with a rubber band...brined squid or octopus is easier to deal with and lasts longer on the hook if you can get it,cut strips or use the legs ...if you can see the fish then you can cast to 'em...get polarized glasses if you don't already...plunkin' works too...if you're gonna plunk you might want to make some chum too...
