Small-bodied native fish project

Australia’s small-bodied native freshwater fish populations have dramatically decreased in recent years, with many populations and some species facing extinction. Small-bodied native fish are threatened by habitat loss, particularly loss of aquatic vegetation and changes in hydrology, as well as predation by introduced species such as Redfin Perch and Eastern Gambusia.

In response to priorities identified under the Murray Catchment Action Plan, interest in small native fish from the community, and alignment with investor preferences (Australian Government and Catchment Action NSW), Murray Local Land Services have developed the Small-Bodied Native Fish project.

The project aims to protect, maintain and improve Small-Bodied Native Fish habitat by funding rehabilitation works in key habitat areas within the Murray region.

The current focus of the project is the Southern Pygmy Perch. This species grows up to 8 cm in length, and prefers slow-flowing habitat with vegetation such as streams, lakes, billabongs and other types of wetlands.

Southern Pygmy Perch were once common throughout southern New South Wales but are now found in only two populations; Spring Creek near Holbrook and Coppabella Creek in the Upper Murray.

These two locations are the focus of works being funded by Murray Local Land Services.

1. Coppabella Creek - Following catastrophic flooding in 2010 and subsequent years, the Southern Pygmy Perch in Coppabella Creek has declined due to changes to the geomorphology and habitat of the stream. To date, works have included weed control, revegetation, and weir repair works. Regular fish monitoring has shown that the Southern Pygmy Perch have increased in numbers and are successfully breeding in Coppabella Creek.

2. Spring Creek, Holbrook – Murray Local Land Services is working with Holbrook Landcare Network to undertake works in Spring Creek to improve Southern Pygmy Perch habitat. A local area management plan is being developed for the species, and works done to date include weed management, erosion management and habitat mapping.
