Shiner bucket temp

[LEfriend]

Hello all was wondering how cold to keep shiners. I think live ones fish better but last Friday most died by mid morning in live well. Heard some people say to keep them cool. So is colder better than warmer? What do some of you do? Thanks in advance for replying.

I bought a standard "tall size cooler" just for bait. Rectangular, taller than wide. Don't know dimensions...same one as I take drinks and lunches in. About size of a minnow bucket. Drilled a hole on the side towards top the to slide aerator hose and stone through, screwed a small picture frame hanger on side to hang the aerator pump on. Put some ice in and works good. Some guys freeze the ice in bottles. I've never had any problem just throwing in some crushed ice or a chunk. (look at Skipper 9's link and mine is the hillybilly version...)
