Listapinnallailmausta
Listapinnallailmausta is a Finnish term that translates literally to "list surface aeration." In practical terms, it refers to a method of aerating a body of water by creating a thin film of water that is exposed to the air. This is often achieved by pumping water to a higher elevation and allowing it to cascade down over a surface, such as a series of steps or a rough incline. The increased surface area contact with the atmosphere facilitates the exchange of gases, primarily oxygen entering the water and carbon dioxide leaving.
This technique is commonly employed in aquaculture, particularly in fish farms, to increase dissolved oxygen levels
