sabiki rigs can be used (they are pe-tied multi hook rigs with glow-beads, flashing and feathers) or you can just use mister twisters on a short shank hook. to either rig use about a 1 oz. bank sinker, heave it out, let it sinkl a bit (but not to the bottom) and reel it in, with an occasional yank. You will fond that depending onthe tide and current the herring will hold in a certain part of the inlet. They are fun to catch.
I don't know about BI, I only catch them consistently at manasquan have not had much luck with sea herring at SRI.
