Fish movement research

Fishtracking app screen shotThe research on fish movement (golden perch and silver perch) was one component of the Long Term Intervention Monitoring (LTIM) program in the Edward/Kolety-Wakool system that evaluated ecosystem outcomes of Commonwealth environmental watering from 2014 to 2019. After five years of on-going monitoring, our researchers now have a much better understanding of where, when and why large river fish such as Murray cod, golden perch and silver perch move throughout the Edward/Kolety-Wakool river system.  Data from this project was used to create animations showing how fish move around during flow events, The tracking data shows the increase in activity in summer and the flood in late 2016. Generally golden perch and Murray cod stayed close to home, although all three species moved larger distances during the unregulated floods in late 2016. Golden perch and silver perch generally moved downstream on the rising floodwaters, and those fast enough to escape the hypoxic blackwater during the unregulated flood in 2016 moved into the Murray River via the Wakool River.

Video of Tuppal Creek

DPIE EES is working with landholders to restore the health of the Tuppal Creek in southern NSW. Through investment in infrastructure and the delivery of water for the environment, we are achieving economic, social and environmental outcomes. Community collaboration is an important and valued part of the environmental water program.

Making more fish

Strong native fish populations are a sign of good river health. DPIE EES is working with recreational fishers and fish scientists to deliver flows that support positive outcomes for native fish and recreational fishers. Local knowledge combined with technical expertise supports the management of water for the environment and provides social, economic, cultural and environmental benefits.

Dr Nicole McCasker of the ILWS research team explains the scientific context for the ideas and actions for water for the environment flows.

Monitoring fish larvae

A story “Working together on fish project” was in the Deniliquin Pastoral Times and the Kyabram Free Press about collaborative research being done with the Edward Wakool Angling Association as part of the Monitoring, Evaluation and Research-Edward/Kolety-Wakool program, March 5, 2020. https://www.kyfreepress.com.au/deniliquin-news/2020/03/05/1066446/working-together-on-fish-project
