For more than 20 years, large timber structures
have been installed across East Gippsland’s waterways to create complex habitats that improve the availability, density and connectivity of shelter
for native fish species.
These enhancements have helped build healthier fish communities throughout East Gippsland’s major river systems, the estuarine reaches and
the Gippsland Lakes.
This long running program is a collaborative effort between the East Gippsland Catchment Management Authority (EGCMA), the Victorian Fisheries Authority (VFA), angling clubs, community groups, and partner agencies, all sharing a commitment to improving waterways for native fish and recreational fishing. Much of the funding has been made possible through the VFA’s recreational fishing licence fees.
“Timber in rivers is natural and plays a vital role in creating diversity and structure within the river system. It provides shelter and food sources for fish and aquatic invertebrates, which in turn support other species, including platypus,” Bec Hemming, EGCMA’s chief executive officer, said.
While the practice decades ago was to remove
wood from rivers, believing it caused flooding, navigation issues and erosion, it is now
recognised as an essential component of river restoration and fish habitat improvement, as well
as supporting bank stability.
“Recreational fishing is extremely popular in
East Gippsland, and improving fish habitat not
only benefits the environment but also supports thriving fish populations for fishing enthusiasts
to enjoy,” Bec said.
“Recently, some of the older structures installed 15 to 20 years ago been replenished, with logs and stumps added to ensure their continued effectiveness.”
Over the years, many different types of structures have been installed using natural materials, including recycled logs with root balls. Some are constructed on the banks and installed using excavators, cranes and barges, while others are strategically placed close to riverbanks.
Many logs have been donated by landholders
who had timber lying around their property.
Rather than disposing of it, they’ve allowed the EGCMA to repurpose it as fish habitat. All timber and root balls are soaked prior to placement to prevent floating and are secured to mimic underwater havens for fish, creating shelter and resting spots for key recreational species such as Australian bass, bream, luderick, and estuary perch.
Other initiatives include bank stabilisation work such as rock armouring and revegetating riverbanks. In addition, fish stocking programs have introduced many species of native fish into East Gippsland’s waterways, improving and maintaining the diversity and abundance of native fish populations.
“Together, these efforts ensure East Gippsland’s waterways remain healthy, resilient, and a haven for both native species and recreational fishers,” Bec said.
