When your fishing with live bait, you’ll have a tough time keeping your bait alive for long without some type of bait well. Bait tanks and wells create a healthy environment that can keep baitfish alive for hours or even days – ensuring you’ll have a steady supply of lively bait at your fingertips!

No matter what sized bait well you’re talking about, the key to keeping bait alive and well is the aerator. This component circulates and oxygenates the water – providing a steady supply of clean, cool, and oxygen-rich water which helps keep bait fish alive and lively.  

Bait wells and tanks come in many shapes and sizes, depending on their intended use case. I’ll break down some of the best bait wells for different boats, as well as how to pick the right one for your needs.

Bait wells (often called live wells) differ significantly in terms of design and functionality.

Larger fishing boats that fish live bait frequently often use fixed bait tanks mounted to the deck. Smaller vessels that only fish with live bait occasionally can use smaller portable tanks about the size of a medium cooler.

Portable Bait Coolers

Portable bait wells are great for smaller craft like canoes, kayaks, and Jon boats. They also work well for larger craft that aren’t used for live bait fishing frequently.

Many of these units utilize a simple and straightforward cooler based design. They’re basically watertight coolers with integrated aerators hooked up to them. The aerators typically run on small batteries or power adapters.

These wells are highly portable, so you can easily swap one out between different boats. Many also double as fishing coolers for general use when you’re not storing live bait inside them.

Fixed Bait Wells

Fixed bait and live wells are larger tanks permanently mounted to the deck of larger boats. They’re normally made from durable rotomolded plastic and typically feature circle or oval-shaped tanks to prevent fish from bumping into the corners.

These wells provide a higher degree of water purification than simple aerator tanks. Integrated 12-volt circulators provide a steady supply of freshwater, which reduces ammonia and waste buildup which can cause fish to act sluggish.

Tournament anglers often use these wells in conjunction with culling systems for keeping fish alive during a competition.

A generous 26 litre capacity ensures you’ll have enough room for plenty of bait, while a spring-loaded lid with rubber latches makes accessing the interior easy from any position. A compact 15 amp lithium-ion battery powers the entire unit, and two power settings let you toggle from continuous to intermittent mode.

Weighing just 13 pounds, the baitwell won’t weight down your kayak excessively. Three rod holders are built into the side of the baitwell, while a convenient integrated net makes accessing bait effortless.

How to pick the right bait well

2 2022 08 best bait wells tanks and coolers how to pick

With a wide variety of bait well sizes, designs, and price points, picking the right one for your vessel can seem like a challenge. Let’s take a look at some of the features to consider when choosing a bait tank.

Permanent vs Portable

The first thing you’ll need to decide is whether you want a permanent deck mounted live well or a compact portable model.

Permanent bait wells can be installed with thru-hull pumps to supply fresh water, or alternatively with outboard pumps. Either way they will circulate the water, providing a steady supply of clean water to the tank – while eliminating ammonia and waste buildup.

Portable models usually don’t feature fully circulating pumps, rather they simply aerate the water contained in the well. However, there are exceptions to this (see the Wilderness Systems Thrive above). These models can keep bait like blue runner, pinfish and ballyhoo alive for several days if used correctly, so don’t think you need a permanent well to get the job done.


The available size on your vessel will largely dictate what size bait well you can hold.

Also consider the size and quantity of bait fish you plan on taking with you. If you plan to use the tank as a livewell for larger fish like bass or walleye, then you’ll need to make sure it has enough volume to keep them alive and vital.
