A healthier, more resilient and sustainable river reach and corridor that is appreciated and enjoyed by all communities of the national capital region.
Native fish and other aquatic species
Eight native fish species occur in the river, but their community health has declined to the point where they now form only 4% of total fish abundance (Lintermans and Osborne 2002). They are threatened by reduced river flows and change to the natural flow regimes; predation by, and competition and disease from alien fish; barriers limiting fish passage up or down the river; loss of instream and fringing vegetation, causing reduced snag availability; increased sediment resulting in reduced habitat complexity; and poor water quality. Threatened fish in the reach include Murray cod, Trout cod, Macquarie perch, Silver perch and Murray River crayfish (listed threatened in the ACT). Other fish that have been found are Golden perch, Mountain galaxias, Western carp gudgeon and Australian smelt.
