About a year ago I fished a pier in NC . Caught a bunch of whiting, black drum at night. I was leaving and near the waters edge I saw flounder moving all around in the 6" deep water. There was a strong floodlight shining in the water. Occasionally I would see a flounder turn upside down - white side up - I assume to see the sand fleas. There were lots of baitfish under the light I made a carolina rig with a long leader and a #4 j hook and cut belly strips from the whiting. I hooked the cut strips one time in the larger end so the hook was well exposed. I could see the flounder pick up my bait. I easily caught my limit, with several door mats in the 6 lb range. The next night I returned with the same rig and mud minnows. I took my 4 battery led mag light and lashed it to the pier aimed at a spot 5 yards out from the pier - my results were even better.
The question - Would this work here? What if I built a PVC frame to hold a high intensity LED light and fished under the light at night? Has anyone tried this? Share your thoughts
