Creek Chubs and Shiners, r two different species, and vary in size.
I like using a combination of both, your average chub will be 4in plus, your shiners average 3.
If targeting pike I like to set 2 rigs with chubs, one with bare circle hook the other with a quick strike rig
the other 2, one a bare octopus hook size 6, and the other whatever jig u like that has a treble hook with 3 minnows attached by tail.
all set at different depths, experiment, find what works for you,
but to answer your question I would get a dozen an a half chubs, and a scoop of minnows, if you use all of that bait, then you had a darn good outing.
good luck on the ice
