Little fish under threat in a big state: south-western Western Australia’s endemic freshwater fishes

Beatty, S.J. and Morgan, D.L. (2008) Little fish under threat in a big state: south-western Western Australia’s endemic freshwater fishes. In: Australian Society for Fish Biology Conference and Workshop, 15-18 Sept 2008, Sydney, Australia.

Abstract

Widespread habitat alterations and impacts of feral species have led to range reductions and population declines of south‐western Australia’s highly endemic freshwater fishes. Some species have been lost from systems and/or are restricted to specific habitats within catchments. Habitat alterations primarily due to salinisation, water extraction and river regulation have compromised many populations. Recent studies on distributions, habitat associations, salinity tolerances, migratory patterns and fishway utilisation has greatly increased our understanding of these key threats and has enabled us to identify populations at greatest risk and to begin to predict future viabilities. This research is currently being used to prioritise populations and develop strategies to help ensure their ongoing sustainability.
