12035: Conserving freshwater fish in south-west WA
This project will fill knowledge gaps relating to the ecology of three of south-western Australia's most threatened freshwater fishes:
- Trout minnow
- Balston's pygmy perch
- Little pygmy perch
The distribution of each species, as well as their migration patterns and the areas critical to their survival, such as spawning habitats, larval nursery areas and summer refuges will be determined. Population estimates will be assessed using telemetry and photo-identification (for the Trout minnow).
A full risk analysis will be completed for each species including: water quality, salinity, changed extraction practices, impacts of feral fish, in-stream barriers and climate change.
Data collected in this project will enable plans for on-ground works to riparian zones and in-stream barriers to be prepared. The information will also aid in assessing and implementing appropriate management arrangements to protect these rare species and their habitat.
