Pool noodles are placed in live wells to protect fish from injury. The soft and buoyant noodles provide a cushioned barrier, preventing fish from hitting the hard surfaces of the live well. This helps minimize stress and reduces the risk of fish becoming injured or even dying. Additionally, the pool noodles also help keep fish in an upright position, ensuring proper oxygen flow and preventing them from getting trapped or wedged in corners. By creating a safe and comfortable environment, pool noodles help maintain the health and well-being of the fish during transportation or storage in live wells. It is a simple and cost-effective solution that fishermen use to prioritize the care and safety of their catch.
