Australian Bass

(Macquaria Novemaculeata)

The Australian bass is a small to medium-sized species of primarily freshwater (but estuarine spawning) fish found in coastal rivers and streams along the east coast of Australia. The species was simply called perch in most coastal rivers where it was caught until the 1960s, when the name Australian bass started to gain popularity.

The Australian Bass is a ferocious fighting fish and while it can grow to a record 3.78Kg (8.3 pounds), most fish range between the one to two pound range with most of them being closer to the one pound range.
Australian Bass can migrate considerable distances upstream and have been historically recorded up to an altitude of 600m (approximately 1980 feet) in the Hawkesbury River drainage, New South Wales.
The pectoral fin appears thicker than most fish, but gives it better control in the water to move quickly while maintaining stability.
