update

Arthur Rylah Institute researchers have been carrying out surveys on native fish populations along the Seven Creeks in the Strathbogie Ranges over recent weeks. Early results are pleasing with a year-on-year increase in numbers of Trout Cod and Macquarie Perch.

As expected, there was an increase in carp numbers but no juvenile carp were recorded. In another positive finding, there was also an increase in river blackfish. The impacts of last year’s spring floods were evident throughout the creek. Bank erosion, instream-scouring, shifting

Read sediment and sand, fringing vegetation destruction and alteration and diseased fish were all noted.

The parasitic anchor worm Lernaea was observed on some native fish (esp. Macquarie perch) at a higher prevalence than in recent years.
