How Does a Livewell Work on a Fishing Boat?

Last Updated on October 16, 2022

A livewell is a holding tank on a fishing boat that keeps fish alive and fresh. The livewell circulates water and oxygen to the fish, and also filters out waste products. Most livewells are aerated, meaning they have an air pump that runs constantly to keep the water well-oxygenated.

If you’ve ever been fishing, you know that keeping your catch fresh is key to a successful day out on the water. But how does a livewell work? A livewell is simply a tank of freshwater that is circulated constantly to keep the fish inside alive and healthy.

Most livewells are aerated, meaning they have an air bubbler to oxygenate the water and prevent the fish from suffocating. The size of your livewell will depend on the size of your boat – larger boats can accommodate bigger tanks. Some livewells even have features like recirculating pumps and filters to keep the water clean and circulating properly.

If you’re planning on spending a lot of time fishing, it’s worth investing in a good livewell system for your boat. Your fish will thank you!

How Does a Fishing Boat Livewell Work?

Most fishing boats have a livewell on board, which is used to keep fish alive and fresh until they are ready to be cleaned or sold. The livewell is typically a large tank of water that is aerated and kept at a cool temperature, often with an ice pack or other cooling system. Some livewells also have a filtration system to remove waste and keep the water clean.

Fish need oxygen to survive, so the livewell must be aerated in order to keep them alive for any length of time. This is usually done with an air pump that runs constantly while the fish are in the livewell. The pump adds oxygen to the water and also helps circulate it throughout the tank so that all of the fish get an equal amount of oxygenated water.

The temperature of the livewell is also important for keeping fish alive. Most species of fish do best in cool water, so thelivewell is typically kept between 50-60 degrees Fahrenheit. An ice pack or other cooling system may be used to help maintain this temperature.

If you’re planning on keeping your catch alive for a while before cleaning or selling it, it’s important to have a good qualitylivewell on board your fishing boat. By following these simple tips, you can ensure that your fish will stay healthy and happy until you’re ready to deal with them!

How Does a Boat Livewell Drain?

A boat’s livewell is a tank of water used to keep fish alive after they have been caught. The livewell must be aerated to ensure the fish have enough oxygen to breathe, and it must be drained periodically to remove waste and keep the water clean. The drain system for a livewell typically consists of two parts: an overflow and a drain plug.

The overflow allows water to escape if the livewell becomes full, while the drain plug provides a way to manually empty the tank when necessary. To drains a livewell, simply remove the drain plug and allow the water to flow out. Be sure to replace the plug afterwards so that no unwanted creatures or debris can enter the livewell.

Do You Leave Livewell Pump On?

Most bass anglers will leave their livewell pumps on when they’re fishing. There are a few reasons for this. First, it helps keep the water oxygenated and circulated, which is good for the fish.

Second, it prevents the water from getting too hot or too cold. And third, if you do happen to catch a big fish, the livewell pump will help keep it alive longer.

What is the Point of a Livewell?

A livewell is a device that is used to keep fish alive and in good condition after they have been caught. The livewell circulates water and provides oxygen to the fish, keeping them healthy until they can be released back into the wild or taken to a local fish hatchery. There are many different designs of livewells, but they all serve the same purpose – to keep the fish alive and as healthy as possible.

Some livewells are small enough to fit inside a boat, while others are much larger and require their own dedicated space. No matter what size or design you choose, a livewell is an essential piece of equipment for any serious fisherman.

How to Fill Livewell on Boat

If you have a boat, chances are you also have a livewell. A livewell is a tank of water that is used to keep fish alive after they have been caught. In order to keep the fish alive and healthy, it is important to properly maintain the livewell.

This includes keeping the water clean and aerated. One of the most important things to do when filling your livewell is to use fresh, clean water. If possible, use water from a hose that is designated for drinking water.

If you must use lake or river water, be sure to treat it with an approved chemical before adding it to the livewell. It is also important to add an aerator to the livewell in order to keep the oxygen levels high. The aerator will help circulate the water and prevent stagnation.

Without adequate oxygen, the fish will quickly die. To fill your livewell, simply attach a hose to the inlet and turn on the pump. The pump will automatically fill the tank with fresh water.

Once the tank is full, turn off the pump and add any chemicals that may be necessary (such as chlorine). Be sure not to overfill the tank as this can cause problems with circulation and oxygenation.

How Does a Recirculating Livewell Work

Any avid fisherman knows that the key to a successful fishing trip is keeping your catch alive and fresh. That’s where a recirculating livewell comes in handy. But how does this clever device work?

Let’s take a closer look. A recirculating livewell is basically a small tank that circulating water to keep your fish alive and healthy. The way it works is pretty simple.

Water is pumped into the livewell from either an external source like a lake or river, or from onboard pumps. A aerator then adds oxygen to the water, which is essential for thefish  to breathe. The beauty of a recirculating livewell is that it can be used in both fresh and salt water environments without any problems.

This makes them perfect for use on boats that are used in both types of waters. Another advantage of using a recirculating livewell is that you can control the temperature of the water, which is important for keeping your fish alive and healthy.

How to Use Livewell on Bass Boat

Using a livewell on a bass boat is a great way to keep your catch fresh and increase your chances of success when fishing. Here are some tips on how to use a livewell: – Fill the livewell with water before heading out onto the lake.

This will help ensure that the water temperature remains consistent and that your fish stay healthy. – If possible, add an aerator to the livewell. This will provide oxygen to the water and keep your fish alive for longer periods of time.

– When you catch a fish, carefully place it into the livewell. Avoid putting too many fish in at once as this can overcrowd the space and lead to stress on the fish. – Monitor the water temperature regularly.

You may need to adjust it throughout the day depending on outside conditions.


A livewell is a tank on a fishing boat that keeps fish alive and fresh. There are two types of livewells: recirculating and non-recirculating. Recirculating livewells have pumps that circulate the water, keeping it oxygenated and fresh.

Non-recirculating livewells rely on ambient water to keep the fish alive, so they must be replenished frequently.
