Interpretation
Key Result: Similar abundances and size classes of River blackfish were detected in all three years. All young-of-year River blackfish were found in the tributaries to the Gellibrand River; a sign that conditions are not supporting recruitment within the main-stem of the river.
Stocking: No stocking has occurred.
