Just wondering if anybody has ever encountered this?I have an urban pond that I fish in and have only ever caught blue gill and warmouth..I've seen a few big catfish in there and plenty of tiny minnows but have never caught a bass no matter how hard I've tried..I've used spinner baits, plastic worms, a crank bait and even real worms with no luck.I haven't seen bass in this pond although I have seen a fish or two strike on things at the surface but I'm thinking those strikes were probably from blue gill..just trying to figure out why the neighbourhood when it was being built would have stocked the pond with everything but bass.there are other natural ponds and lakes in this neighborhood that have bass in them but this one I'm not sure..any recommendations on a bait I can use that only bass eat and not the others in the pond? Thanks
