Marine Ecology
The river is home to several species of fish. In the lower reaches of the Yarra mainly Southern black bream and jellyfish and in the upper reachers smaller quantities of European perch (redfin), Macquarie Perch, Brown Trout, Murray Cod and Freshwater Catfish. However almost all of the fish are contaminated with heavy metals including arsenic and not fit for human consumption. Dolphins have been known to venture upstream as far as South Yarra, and serve as an example of the increased salinity of the river's lower reaches.
