If there are docks, stick ups, or overhanging trees, fish the shady side. Fish all the structure, anywhere something casts a shadow on the water. Ponds have more lily pads for shade and concealment so the Rock Bass will be hiding in the lily pads. Late April is a prime time to target Rock Bass. The most effective baits are nightcrawler and perch minnows.
Most anglers start with two poles.
On one pole add snap swivel to your line. The bobber should be only big enough to support your offering. Add a nightcrawler as bait and cast out about 30 feet from shore. On the second pole have the same set up except the bobber is four feet from the hook and the bait is a perch minnow. Cast this offering about twenty feet from shore.
