Abstract: Construction of mills, dams and other structures in rivers and streams, and the withdrawal of water for irrigation or cooling industrial facilities vital to social and economic progress, have impacted the survival of marine life. Barriers and guidance or collection nets can protect fish and aquatic species while allowing water to flow unimpeded for commercial and industrial use. However, nets can attract aquatic growth, fill with debris, degrade with environmental stress, and be expensive to operate and maintain. A closer look at the technical developments of materials and net designs in diverse settings can offer guidance that will be of use to engineers and community stakeholders in varied environments who are striving to meet similar challenges. With careful consideration of bathymetry, topography, pool fluctuation, water flow, debris, weather, deployment, the principles and materials outlined can be adapted to environments around the world. Successful implementation will allow humans to continue to harness our most valuable resource with respect for the wider social and economic health of the planet.
