You just need to cool it down a little, The main reason for the cool water is that is holds o2 better. If you have a good recirc system and add some ice yoy will not lose many fish. There are some tourneys guys out there that DO NOT CARE for their fish, I have seen this too many times, they also do not take time to bleed the air bladder, this is something all should know, if you catch fish from deep water, I saw several floating at Barkley the weekend before last from a USA bassin tourney that were still moving there fins but were upside down, if these fish had had their air bladders bled that might have survived, I see this at out tourneys too, as there are some that do not care or know how to care. GEO not all of us tourney guys are arrogent, as us that are very serious know that in order to enjoy this sport and to do this sport we have to have fish, and we strive, esp in the KBFN to keep our fish alive. A good tip I learned from another very good tourney angler is that he puts ice in livewell first thing in the Am and while waiting to blast off, run a little water into well, and then when you get to fishing spot fill up live weel and add additives. like Rejuvinade,etc and then run recurt the rest of the day, the additives help keep amonia levels down from fish waste as it is not good to readde water from the lake as it is warmer than than the livewell water. He does not lose many fish in these hot weather tourneys.
