and another tip (off topic)
if you have a small cooler like I do, enough for 4 or 5 cans and that's about it, stick the cooler itself in the freezer a day or two ahead of time. I leave mine in the freezer full time unless I'm at the lake. That little cooler makes a dandy minner bucket. It fits inside the bigger cooler, with some ice AROUND the small cooler, minners inside and an aerator inside the bigger cooler as to pump cool air into the small bucket. Keeps minners alive for 12-14 hours out in the sun in 100 degree air like today. Crappie season for me is in the middle of summer so I gotta keep minners alive the best I can.
don't use ice directly in the minner bucket. It'll shock them and most ice is tapwater, meaning it's got clorine and other stuff in it which kills the lil fish. So I sometimes use a 1 gal freezer bag that is full of water but frozen, and use that to keep em cool if needed. With the way I keep my minners in a cooler, it's not needed most of the time but I've done it in the past. Drop of H2O2 works too but just one drop is all that's needed.
