| Fish passage
Due to the complexity of existing weirs and flow management systems, finding a one-size-fits-all solution for fish passage in the Menindee Lakes region is challenging. This trial serves as an experimental approach to gauge the feasibility of temporary passage methods while DPIRD Fisheries and partner agencies work toward long-term solutions. “Unfortunately, there is no one-size-fits-all solution to
restore fish passage in this system,” Sloan noted. “This exciting trial is about finding a cost-effective temporary solution while DPIRD Fisheries develops a Business Case with partner agencies to find effective and permanent fish passage solutions.” A significant benefit of the Fishheart system is its
potential scalability. If successful, this technology could be deployed across multiple river systems in Australia, addressing fish migration barriers on a larger scale. The adaptability of the design allows for modifications to suit different river conditions, making it a versatile solution for fish passage restoration nationwide.
The future of fish passage technology The trial at Menindee is expected to offer invaluable
insights into the viability of Fishheart’s technology in an Australian context. With successful implementations in Europe and the United States, Fishheart Ltd. has proven experience in developing solutions for large-scale migratory fish passage. However, testing this system in Australia’s unique river conditions will provide essential data to determine its suitability for widespread adoption. Beyond its immediate ecological benefits, this initiative highlights the importance of international collaboration in tackling environmental challenges. By working closely with local communities, government agencies, and scientific experts, the project aims to set a precedent for future conservation efforts.
Community and environmental impact Local engagement plays a crucial role in the success
of this initiative. Since August 2024, NSW Government representatives have been consulting with the Menindee community to discuss the trial and gather feedback. Understanding local perspectives and concerns ensures that the project remains transparent and aligns with broader conservation goals. The anticipated impact of the trial extends beyond fish passage restoration. By improving connectivity between the Northern and Southern Basin, the project aims to revitalize fish populations, enhance biodiversity, and contribute to the overall health of the Lower Darling-Baaka ecosystem. This, in turn, supports commercial and recreational fishing, cultural heritage preservation, and long-term waterway sustainability. As native fish populations continue to face threats
from human-made barriers, climate change, and habitat degradation, the need for effective fish passage solutions has never been greater. The Menindee Tube Fishway Trial is a promising step toward restoring the natural balance of Australia’s river systems, ensuring that native fish can once again move freely through their historic migration routes. With this ambitious trial set to commence soon, all
eyes will be on Menindee to see how this innovative technology can contribute to the future of waterway restoration in Australia.
