Livewells are tanks found on many fishing boats, deck boats and pontoons that are used to keep bait and caught fish alive. They work by pumping fresh water from the lake into the tank and then back out. This flow of water keeps the water fresh and oxygenated, allowing fish to breathe properly.

Livewells are tanks found on fishing boats, deck boats, and pontoons
A constant flow of raw water keeps the temperature in the well relatively stable. Raw water means fresh oxygen and the removal of waste like ammonia that builds up from excretion. A constant flow of raw water also keeps the temperature in the well stable at approximately the same temperature as the surrounding surface water.
There are a few different approaches to keeping the water in a livewell moving and aerated. You can pump raw water from outside the boat into the well and then drain it back overboard, circulate the water already in the well through a closed system, or pump air into the water. Pumping raw water from outside the boat through your well is the best way to keep the fish happy.
Livewells are carefully regulated to keep fish alive with the correct oxygen and water pressure. They also give you a hidden space to keep your fish, so your boat won't stink up or become crowded. Some argue that livewells are the most ethical way to store caught fish, as they can remain in regulated water on your boat.

They keep bait and caught fish alive
Livewells are tanks found on many fishing boats, deck boats and pontoons. They are used to keep bait and caught fish alive by pumping fresh water from the lake into the tank and then back out. This flow of water keeps the water fresh and oxygenated, allowing fish to breathe properly.
There are a few different approaches to keeping the water in a live well moving and aerated. The best way to keep the water fresh is to pump raw water from outside the boat into the well and then drain it back overboard. This provides fresh oxygen and removes waste like ammonia that builds up from excretion. It also keeps the temperature in the well relatively stable.
Another approach is to circulate the water already in the well through a closed system. This can be done with a pump that mounts on the outside of your transom below the waterline and pumps water through a hose to your well.
A third option is to pump air into the water. This can be done with an aerator that agitates the water to stimulate the oxygen in the water.

The constant flow of raw water also keeps the temperature in the well relatively stable.
There are a few ways to collect raw water. The simplest is with a pump that mounts on the outside of your transom below the waterline and pumps water over the transom through a hose to your well. Raw water means fresh oxygen and the removal of waste like ammonia that builds up from excretion.
A pump pulls water in through the hull and into the livewell. A drain allows the water to escape and be replaced. The aerator agitates the water to stimulate the oxygen in the water.

Livewells are tanks found on many fishing boats, deck boats, and pontoons that are used to keep bait and caught fish alive. They work by pumping fresh water from the lake into the tank and then back out. This flow of water keeps the water fresh and oxygenated, allowing fish to breathe.
There are a few different approaches to keeping the water in a live well moving and aerated. One way is to pump raw water from outside the boat into the well and then drain it back overboard. This is the best way to keep the water fresh and oxygenated as it provides a constant supply of fresh oxygen and removes waste like ammonia that builds up from excretion. It also keeps the temperature in the well relatively stable.
Another approach is to circulate the water already in the well through a closed system. This can be done with a pump that mounts on the outside of the transom below the waterline and pumps water through a hose to the well. This method may not provide as much oxygenation as the first method, but it still helps to keep the water moving and prevents stagnation.
A third option is to pump air into the water. This can be done with an aerator that agitates the water to stimulate the oxygen in it. This method may not provide as much fresh water as the first two methods, but it can help to keep the water oxygenated and fresh enough for fish to breathe.
