keeping mousies alive

[Chrisper4694]

i buy a bulk of mousies at the beginning of the ice season cause they're so expensive and the bait shops run out a lot of times by me.

last year i had many dead ones by the second half of the ice fishing season. I tried to only take what i was going to use with me in a puck and left the rest in a original packing in the fridge then put what i didn't use back in and so on and so forth.

any one have any tricks to keeping these things alive longer?
