We had a number of dead fish this past weekend - too many. As you know, I handle each bag (as little as possible). It was quite clear that some teams cooled their fish very well while others had not. It is critical that each team bring sufficient ice to each tournament once water temperature have reached 75F. As a guide a one 8-pound block (or two frozen half-gallon milk jugs) of ice cools a 30-gallon livewell 10 degrees F for about three hours. That means you need 6 half-gallon bottles minimum for one of our tournaments (I use 8 and juice bottles because they fit in my coolers - have have some lunchbox style coolers that hold 2 or 3 depending on style [walmart]). You will need more if you are going to change over water during the day, suffer some melting prior to adding to the livewell or have a larger livewell.
