It’s happened again – yet another independent biomonitoring report into the Russell River confirms the river is in good health. Our Lonnavale freshwater hatchery is located near the Russell River and the report indicated there was “no evidence of impacts of the hatchery on the composition and health of the macroinvertebrate fauna downstream of the hatchery”. All three assessment sites (one upstream and two downstream (at 50m and 200m) of our hatchery) (once again) received an A rating (against the AUSRIVAS assessment protocol). You can read the report below:
You can read past reports here:
Key findings of the Autumn 2020 report included macroinvertebrate fauna of all three sites were assessed as holding characteristics of relatively clean-water environments while algae levels were “very low at all three sites”.
Key findings of the Spring 2019 report included “minimal evidence for impacts (of the hatchery) on the health of the macro-invertebrate fauna and algae growth downstream”.
