I've got two stories that are similar to this. Last year, early in the spring, I stopped at city lake that was on the way to an appointment. I decided to try my luck and was throwing GULP turtle back worms along the bank. I began to notice the blue gill were cruising around the area and took an interest in the GULP. They weren't big enough to swallow it but they would bit the tail and pull on it. I was tempting this one and he was an aggressive little ***. He kept going after the GULP. But this one time, as I was dragging him along, there was an explosion out of the weeds and this bass came shooting out and the blue gill was gone!
Several weeks later, I was pre-fishing from the bank before a club tournament. I noticed that the blue gill were bedding along the bank and knew that we had an early blast off the next morning. Figuring that bass might move into the area to feed on some of the blue gill, I decided I would start there. But a storm came through just before blast off and we had to delay for about 45 minutes. When I got there the water was milk chocolate, but I decided to throw a few anyway. I was using a 7" turtle back worm to try and keep the blue gill off of it, but they kept nipping at the tail until it was down to about 3". I laughed and decided to make a long cast to clear some of the mush on my reel before re-rigging and a 17" bass hit the remainder.
