Interesting question and I don't know but have my doubts as to effectiveness. I've night fished for bass and crappie but not bluegills. On bass I've used lures that made some sound and vibrations in the water. On crappie, I've used floating lights that drew minnows and hence crappie.

But my bluegills are sight feeding on floating feed. I haven't tried sinking feed in over 20 years. I expect that they hit sinking feed as it is sinking or picking it off the bottom probably from smell. The downside of sinking feed is that we don't know how much is actually eaten. Interesting question and I think it night be worth an experiment. Good chance that some will come to the sound of the pellets hitting the water. This will probably make my Wife roll her eyes again.

It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.
