These aftermarket systems transform insulated containers into functional environments for keeping live bait or caught fish viable for extended periods. Typically, these kits comprise a pump for circulating water, an aerator to increase oxygen levels, and necessary plumbing connections for inflow and outflow. For example, a standard cooler can be retrofitted with such a system, providing a portable and cost-effective alternative to built-in livewells.
The utilization of these retrofitting components offers multiple advantages, including enhanced portability, affordability compared to installing a dedicated livewell, and the ability to maintain optimal water conditions for aquatic species. Historically, anglers relied on rudimentary methods for preserving their catch or bait, but advancements in portable aeration and circulation technologies have significantly improved the success rate of keeping them alive. This has a beneficial impact on catch and release fishing and maintaining the quality of bait for subsequent use.
