Why some minnows die faster on the hook than others. I've had lively crappie minnows die within minutes compared to others lasting 1 hr or more on the hook. The ones dying fast I check for missing scales to see it was hit, with no scales missing it puzzles me why they die so fast.

Yesterday I put on a big healthy 2" chub on a dead line setup hanging over the boat. I checked it 5 minutes later, dead as a doornail. No scales missing so why would it die so fast?

For me they last longer when hook only thru open mouth thru nostrils. When retriving my bobber they come in natural head first thru the water compared to hooked in tail, less stress in nostril than tail I'm thinking.
