I've spent some time chasing creek chubs for bait - but no luck. I use a minnow trap like the one below. I've been using pellet dog food for bait but managed none on my trap the last two times. I've let the trap soak for one night, then two nights - no luck.
Not sure if it's the wrong bait or the wrong trap.
I should add that there are definitely chubs in that creek. Basschaser had much better results in the same creek with a different trap.
