Long term, or just on a single trip?
We use a lot of Emerald Shiners that die real easy.
In my boat I wired in a switched 12v. air pump, with a diffuser on the tip of the air hose going to a 7 gal. bucket.
Keeps them alive for a few days if you change water.

Old Fishermen never die, we just get reel tired.

May you build a ladder to the stars
and climb on every rung.
May you stay......Forever young
