Waterwatch case studies

Macquarie Perch Love Waterbugs

Waterwatch coordinators have used their skills in collection and identification of waterbugs to inform habitat improvement for Macquarie Perch in Hughes Creek.

The endangered Macquarie perch (Macquaria australasica) lives in slow rivers with deep holes and its diet consists of aquatic insects. Waterway managers are re-establishing depth and shelter in the creek and re-introducing large wood (snags) to improve habitat quality. Surveys of waterbugs have been done before and after work to evaluate the success of the works.  Efforts to improve habitat for the fish is expected to result in improved waterbug populations as a food source not only for Macquarie perch but for other fish and birds.

Waterbug diversity and abundance have also been used to assess the water quality of rivers in the Goulburn Broken region including Rubicon River at Tumbling Waters, King Parrot Creek at Flowerdale, Acheron River at Tom Park and Yea River at Devlin’s Bridge.  These sites are part of the priority stream assessment program delivered by the Goulburn Broken Catchment Management Authority.

Continual learning and training opportunities are provided through Waterwatch. For further information on Goulburn Broken Waterwatch monitoring program, visit http://www.gbwaterwatch.org.au/contact.php
