Well this has turned into a good topic
The oxygen tank I have looks like it will last 4 full days of fishing.
Tomorrow will be the full field trial. My plan is to put 9 crappie in with oxygen and change the water with cool water pulled from 10 feet deep every 3 hours.
The test will be can I keep them alive enough to turn loose after 12 hours. Their incentive to cooperate,, well we all know that answer. I will eat them.
I will be connecting a seperate line to my minnows and see if that works also.
Jwhite Thanks because I was getting really close to being grounded from posting.
