This weekend my daughter and I caught one channel cat each. We were fishing at the Lake Lewisville barge and dropping straight down then coming up off the bottom about 6 inches. She was fishing for crappie and wasnt doing well so asked me to put some liver on for her. She was using an ultra lite rod and reel, a few minutes later she asked me to look at her pole and see if I thought she was getting a bite, the tip was barely moving up and down but I told her yes it is a bite, about a min later she reeled in about a 1.5 lb channel cat. Later I got a bite with my medium/heavy action rod and the tip was barely moving again, so slight that at first I thought the rod was just moving from the movement of the barge. I caught about a 1.5 pounder also. Seemed like very light bites to me. Is this common?
