The greater the volume of water a livewell can hold, the greater number (or pounds) of fish that can be held. With a pressurized oxygen delivery system that will maintain saturated oxygen conditions, anglers should observe a ratio of no more than 1 pound of fish per gallon of water. Be aware that this ratio will tax conventional re-circulating aeration systems and anglers must take even greater care to maintain desirable livewell water temperatures and maximize aeration.
When surface water temperatures increase above 75 degrees F, flow-through aeration alone may not be adequate, and may be lethal. 10 degrees F increase in water temperature will cause an almost 20 percent increase in respiration rate. To make matters worse, not only does the fish's oxygen demand increase, the warmer water may hold 10 percent less oxygen.
Now by these notes I figure a tournament catch of 150 lbs plus would take a 200 plus gallon livewell in the summer months and at least 150 for temps below 75 degrees.
Who can afford or even carry a 200 gallon livewell.??? :crazy:
