When a fish gets caught, it makes a commotion. The other fish get spooked because they see this one fish splashing around and then disappear. Think about three targets all in one line. Targets are at 10', 20', and 30' away from you (you are stationary through this). All three targets hold fish. If you cast to the 30' target, you're pulling the fish through the other two target areas and spooking those fish. The correct way to do this is to pull the fish off the 10' target first, then go to 20', pull the fish off it, and then hit the 30' target. Of course, there are times when you can run a motor through a mudpuddle and the fish won't even be fazed by it.
