A recirculating system designed for marine environments to keep captured aquatic life healthy until needed. These systems consist of a pump, plumbing, aeration devices, and often temperature control mechanisms, all integrated to maintain a suitable habitat within a contained tank. A common application is among anglers who use it to preserve caught fish for later consumption or live bait for ongoing fishing activities.
Maintaining the viability of organisms held within a marine tank presents significant advantages. It allows for the practice of catch-and-release fishing while minimizing harm to the fish. Furthermore, it ensures a readily available supply of fresh bait, increasing the chances of a successful fishing excursion. Historically, simpler versions involved buckets or open tanks, but advancements have led to sophisticated, electronically controlled environments that optimize oxygen levels, temperature, and water quality.
