Trout Minnow

NODE LEADER: 

Dr Paul Close (UWA)

BACKGROUND:

Listed as CRITICALLY ENDANGERED, the Trout Minnow is one of Australia's rarest fishes. The species is found in south-eastern and south-western Australia. While some east coast populations are diadromous (i.e. they have a marine larval stage), the Western Australian populations are land-locked and spend their entire life in fresh waters. 

Currently we only know it from the Goodga, Angove and Kent Rivers, although our aim is to find out more about its life-cycle and distribution in the Kent River.

DEMONSTRATION SITES: 

Goodga and Kent Rivers.
