Central Billabong
It was a perfect December day for releasing fish on the Billabong and Yanco Creeks. Under a bright, sunny sky, Yanco Creek and Tributaries Advisory Council Inc (YACTAC), supported by Refreshing Rivers and DPI Fisheries grants, released 25,714 golden perch fingerlings.
The fingerlings, sourced from Tara Native Fisheries, Corowa, were part of a broader effort with Edward River Council and Jerilderie Fishing Club that saw over 50,000 fish—including Murray Cod—released into key sites across the region. Wanganella, Conargo, Jerilderie, and Morundah all played host to this regional initiative.
Golden perch, also known as yellow belly, are a native species of the Murray Darling Basin. These medium-to-large fish typically measure less than 40 cm and weigh around 4 kg, though some can grow much larger. Once abundant, golden perch populations have suffered declines due to habitat degradation, invasive species such as carp, and river regulation.
Golden perch fingerlings thrive on a diet of plankton, invertebrates, small shrimp, and worms. To give them the best chance at survival, healthy habitats are crucial. Vegetation like water plants, rushes, and sedges provide vital cover for young fish, offering protection from predators and enhancing water quality.
The long-term goal is to see golden perch populations in the Yanco Creek System become self-sustaining. The current fish population in these creeks is dominated by carp, which make up an estimated 70–80%. This imbalance disrupts waterways, making efforts to boost native fish populations like golden perch even more essential.
Golden perch are known for their ability to travel. Adult fish can journey up to 1,000 kilometres through river systems, seeking suitable conditions for spawning and survival. However, their migration and reproduction are often hindered by obstacles such as weirs and dams. These barriers disrupt natural river flows and the cues that trigger spawning.
"Releasing fish is just one piece of the puzzle,” said Andrea Mitchell, YACTAC.
“It’s part of a bigger effort to improve waterway health and address challenges like invasive species. We’re working towards a future where golden perch can thrive and reproduce naturally. "
The golden perch release marks the continuation of YACTAC’s commitment to restoring local waterways. In early 2025, YACTAC plans to release eel-tailed catfish fingerlings as part of these broader efforts. These initiatives align with the Refreshing Rivers Program and YACTAC's Strategic Plan 2020–2030.
A shared community commitment to the health of Yanco Creek System made this a day to celebrate. With golden perch now swimming in the creeks, the hope is for a better future for the waterways and the communities they sustain.
Coleambally Central School students embraced muddy boots and big smiles as they joined YACTAC on November 27th to plant native wetland species at the Leeds property, “Broome”, on the Yanco Creek. The students planted jointed twig rush, spike rush, and sedges to restore a backwater habitat.
You know you've hit on something big when farmers stop what they are doing, in one of the busiest months of the year, to keenly participate in a workshop. Interest in the African Boxthorn biocontrol pilot program demonstrated just how much of a problem Boxthorn is.
Over the course of several events in late 2022 and early 2023, significant work has been undertaken to restore fish habitat on the Colombo Creek. Schoolkids helped plant trees, while a separate event was held to reduce carp numbers through electro-fishing.
What's not to love about being outdoors amongst the redgums, planting and restoring wetlands on a sunny day, with kids having fun in the mud and a bbq? Plus, a great result for habitat and vegetation at this property on the Yanco Creek.
Central Billabong landholders celebrate the incredible success of willlow removal projects over the past 15 years, which have turned clogged creeks into broad, navigable waterways, flanked by redgums and revegetation plantings, and home to native fish and birds.
