if you have a live well it needs an ice block dropped in when you hit the water , if not right into an ice chest with an ice block , remember to rotate the fish after you have a few so the ones not on the actual ice get to chill on it , sometimes the fish on the pile dont get chilled if you don't rotate them and not sure about you but I hate to see a washed out pale crappie in my ice chest .
but to be sure it is way way WAY easier to just toss them back where they originated from .....
