Use a float to keep your bait off the bottom and away from the crabs that will otherwise eat it. Some anglers also know that striped bass feed on baby flounder. Flounder have to be 11 inches to keep. A great lure that imitates a baby flounder is the Petri-Fish. The Petri-Fish 'fake flounder' lure really looks like a live flounder in the water.
Striped bass love the lure.
I have landed two good fish with this bait. It comes in three sizes but the Petri-Fish Jr. is my favorite. The inventor, Steve Petri, is currently working on a smaller version of the lure which I am sure will be just as good if not better than the larger lures. I'm told the smaller version will also work on fluke. Chumming also works very well with striped bass.
