Louse Point is a nifty spot where the young bluefish (“snappers”) come in to feast upon minnows.
You can chase them with really simple tackle: light monofilament line (4 to 8 pounds) and a lightweight rod. My kids used the classic Zebco 33 with great success. Harvey at the Tackle Shop in Amagansett can sell you popper rigs, which consists of heavy monofilament line, a cone bobber, and a long shank narrow hook with either a flashy skirt around it or a rubber fake eel cover on it. Both word great, and a popper rig costs maybe $8 or $9 and will last forever. If you really want the snappers to go berserk, add a dead minnow to the hook. (Harvey also sells those, and other bait.) Its is simple fishing—cast and reel. And look for surface disturbances—the big busy patches that happen when a school of snappers encounter a school of minnows.
Fishing tends to be best when the tide is coming in. So check the tides online.
Fly fishermen can bag snappers with ease. Use floating line and chuck a Clouser Minnow or other streamer. Harvey also sells flies with stainless steel leads, as snappers have vicious teeth that will shred line. If you chuck one of your own flies, best include tippet that is thick enough to take the abuse. And strip as fast as you can—bluefish are blazingly fast and love rocketing baits.
