An innovative fishway to restore migration for freshwater fish

Back to search results
Fish are the most threatened of freshwater vertebrates. Internationally, fish populations have declined 76% over the past 40 years. A primary contributor to this loss are dams obstructing migrations critical to many fish life-cycles. UNSW scientists and engineers have developed an innovative fishway to restore migrations over high dams. The project builds on successful fish attraction trials as well as numerical and physical modelling. The study will move to larger scale, optimising fishway design by large-scale experiments with live fish. The objective is a final design to restore fish passage to previously obstructed river systems internationally.

Due to its interdisciplinarity, the project is open for HDR candidates from a range of disciplines within Science and Engineering. While it will be beneficial that the HDR candidate has some understanding and background of either ecology or applied fluid mechanics, the diverse expertise of the project team will ensure that the HDR will receive adequate training in a range of areas relevant to the project.

The project will be mostly experimental and the HDR will be based at the Water Research Laboratory in Manly Vale for experiments to improve the fishway design and for fish tests. The project may also involve some numerical modelling and field tests and required training will be provided.

The HDR candidate would need to be self-driven, motivated and willing to learn new project-related knowledge from both engineering and ecology.
