The method that i use on the cumberland smallies is fill up your livewell and put the fish on the side with the pump nozzle.. make sure the nozzle is ABOVE the water level and when i squirts it makes bubbles in the water.. on the other side i put 2-3 gallon milk jugs with frozen water in them.. dont put all of the jugs in at once but keep adding them throughout the night.. i also us rejuvinate in the water as well.. i always put 2-4 cap fulls of rejunivate in the water.. Knock on wood we havent lost a fish in a couple of years using this method, and the fish are so lively that they try to jump out when you open the livewell up.. And when the temp get in the upper 80's or 90's like it is on cumberland this really helps..
