I have recently started fishing for crappie at an old wooden dock along the sandusky bay in sandusky, ohio. Me and some friends went there after not having much luck for perch on the lake and met a guy who had about 13 crappie from this dock. I have been there three times now for a few hours and havent gotten a single bite. What am I doing wrong??? I have tried using 1/16 ounce jigs with different colored artificials worms with tails on them. I have tried using these jigs with the artificial worms with a bobber. I have tried using a vibrax lure(similar to a rooster tail). Nothing seems to be biting. Please reply with suggestions! Thanks!
