Australian Bass grow to 60cm and can weigh up to 4kg, although more frequently caught at around the 35cm or 1kg mark. Australian bass in their natural river habitats are not to be underestimated; they head straight for the nearest snags (sunken timber) when hooked and light but powerful tackle and stiff drag settings are needed to stop them. Do more with Bing Maps. [4], Australian bass (Macquaria novemaculeata) are closely related and very similar in appearance to estuary perch (Macquaria colonorum). [15] Australian bass sperm have no viability at or below 6 ppt, but are most viable at 12 ppt, the latter probably being the most relevant fact. The Australian bass (Macquaria novemaculeata) is a small to medium-sized, primarily freshwater (but estuarine spawning) species of fish found in coastal rivers and streams along the east coast of Australia. If Australian bass are prevented from migrating to estuaries for breeding by an impassable dam or weir, then they will die out above that dam or weir.

Surveys caught most Australian Results from recent research using genetic MtDNA analysis indicate Australian bass and estuary perch do belong in a separate genus to golden perch and Macquarie perch, and has resulted some in researchers resurrecting the genus Percalates and referring to Australian bass and estuary perch as Percalates novemaculeata and Percalates colonorum respectively. Body colour may change with sexual maturity. Such cover does not need to be in deep water to be used; Australian bass are happy to use cover in water as shallow as 1 metre in depth. Australian bass have also been stocked into several large impoundments in recent years such as Lake Bullen Merri in the south west and Blue Rock Dam and Lakes Narracan and Glenmaggie in Gippsland. Genetic population structure of the catadromous perciform. A rather surprising and unexpected finding of this research is that the putative genus Percalates (i.e. Morphological and biochemical systematics of Australian freshwater and estuarine percichthyid fishes. Responsible fishermen now avoid fishing for wild Australian bass in estuaries in winter, so that this increasingly pressured native fish can spawn in peace. The species is readily caught with hook and line or by lures but the resource is probably under-utilized at present. Jerry DR and Cairns SC (1998).

(The generic name Percalates is a compound of the generic names Perca and Lates, and arose from an early, erroneous taxonomic belief that Australian bass were an old world perch related to barramundi (Lates calcarifer)). It may be a Latin rendering of "in an unusual manner" (nove) and "spotted" (maculeata) and refer to the specimens he examined being "spotted": The most likely explanation however is a Latin rendering of "nine" (novem) and "spines/needles" (aculeata) and refer to the spiny dorsal fin, which is relatively high and sharp and which Steindachner indicates is usually (but not always) composed of nine dorsal spines: Australian bass have a moderately deep, elongated body that is laterally compressed.
