The project will directly assess and address current and future threats
faced by south-western Australian endemic freshwater fishes such as climate
change and feral fish within the target area. The project will use the Balston’s Pygmy
Perch (BPP) fish species as a flagship species for conservation (listed as Vulnerable EPBC Act) and elevate its
status to enhance public awareness of aquatic ecosystem issues.
·To provide an updated
distribution of BPP in the target area and determine the degree of population
decline in wetlands and river sites from previously known existence (past 20
years) within the project area. To identify
dry-season refuge pools and all potential instream barriers to seasonal breeding
migrations across key catchments to guide future management of current and
future threats to BPP and other species.
·To prioritise barrier
mitigation and the protection of key refuge habitats of the BPP (and other
freshwater fish species) with the SWCC region.
·To enhance aquatic
ecosystem health and reduce threats to BPP and other native aquatic fauna by undertaking
targeted feral fish control at four strategic sites.
·Use Balston’s Pygmy
Perch as a flagship species to promote the conservation of freshwater
ecosystems across the SW region.
This collaborative project (with the Murdoch Estuarine
Research Group, the Department of Fisheries, GeoCatch, Department of
Water, City of Busselton) aims to determine the movement patterns and spatial
and temporal distribution of the Black Bream and Sea Mullet within the Vasse
Wonnerup system which has been the subject of regular fish kill events.
Using an acoustic tracking approach that the FFGFHU has recently used to
successfully track the movement patterns of large feral goldfish in the...
The FFG is undertaking a new study that is examining the
conservation status of the unique aestivating freshwater fishes of
south-western Australia; the Gondwana relic known as the Salamanderfish (Lepidogalaxiidae
salamandroides; the sole member of the Lepidogalaxiidae) and the
Black-Stripe Minnow (Galaxiella nigrostriata; one of only three members
of Galaxiella). These represent Western Australia's only two aestivating (survive
in seasonally inundated systems by burrowing into mud) freshwate...
