Recently watched the bilge podcast with the BASS director of conservation and he had several great points about fish health, two of those really stuck with me. ~One, he cant support any products for fish care because they are not FDA approved. In fact one of the best that is no longer on the market caused cancer, something to think about when we release these fish back into the wild, they have the potential to be consumed by another human.
~Two, and I think is the best information for any tournament angler is keeping the live well water roughly 8-10 degrees cooler then the lake dramatically increases the chances of long term fish survival.
