I cant say ive caught 3 bass on one bait but i have shot 3 shad in one shot bowfishing one night. It was all luck bc i was actually shooting at a gar and after i shot my arrow took off and the gar was still there. When I real it in there was 3 shad on the arrow. We took a pic on my phone but i lost it when the phone died last year.
No skill just luck.
So i guess if thats possible it should be possible to hook three bass on one bait.
