Can anyone answer this?

Brian -
Who is driving around in a medium sized jon boat at night, with lights all over it aiming into the water, and a couple of guys with what looks like large butterfly nets dipping into the water?

This boat came by my dock last night about 9:00 pm, about 5 feet from the end of my pier and kept moving along down the shoreline.
