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.

Famous quotes containing the words marine and/or ecology:
“People run away from the name subsidy. It is a subsidy. I am not afraid to call it so. It is paid for the purpose of giving a merchant marine to the whole country so that the trade of the whole country will be benefitted thereby, and the men running the ships will of course make a reasonable profit.... Unless we have a merchant marine, our navy if called upon for offensive or defensive work is going to be most defective.”
—William Howard Taft (1857–1930)
“... the fundamental principles of ecology govern our lives wherever we live, and ... we must wake up to this fact or be lost.”
—Karin Sheldon (b. c. 1945)
