Australian fish species have limited swimming abilities compared to some species overseas. To protect them, we need water velocities under 0.1 metres per second at the point of water diversion.
Fisheries scientist Tom Rayner explains what’s happening at the interface between fish and screens, including how modern screens achieve these low velocities whilst delivering required water flow. He also describes the research looking at how fish exclusion screens help fish adults, juveniles, larvae and eggs.
He also outlines how this research is being collated to create guidelines for a new best practice around screen design, manufacturing and operations.
