Are we talking about golden shiners here? Those things are pricey and they die if you look at them wrong.
Biggest myth in live bait fishing.
Everyone claims they die so easily but I’ve never noticed any difference than any other minnow.
Keep them cool and oxygenated and buy them from a good bait shop. If they’re dying before getting to use them you’re doing something terribly wrong or the bait shop is doing something wrong and the minnows were unhealthy when you bought them.
I’d guess a limited number of goldens will be available in most areas , the late ice out has me thinking the opener might come before the spotails move shallow and become available though.
