Interpretation
Key Result: Nine Australian grayling were detected in 2017 and five in 2018. While no Australian grayling were detected in 2019 during sampling for the Native Fish Report Card Program, individuals were recorded by the Victorian Environmental Flows Monitoring and Assessment Program (VEFMAP) in 2019. Australian grayling sampled during VEFMAP ranged 8 – 22cm, including six young-of-year fish. Please note VEFMAP used different gears to the Native Fish Report Card so results are not directly comparable.
Stocking: No stocking has occurred.
