Method, System & Apparatus for Asymmetric Flow Guidance of Fish
An apparatus for guiding fish through a body of water having a water flow includes one or more hydrofoil element oriented in the body of water to produce an asymmetric flow field that has a fast, low turbulent flow on one side of the element and a slow, high turbulent flow on the other side of the element. Positively rheotactic fish have a preference for one side versus the other and so are guided in a desired direction. Systems and method that utilize the apparatus can be used to guide fish away from infrastructure such as dams, locks, levees, flood weirs, and other diversion points.
