== Reproduction ==
Although their reproduction is poorly studied, Australian salmon are all known to be "pelagic spawners"; that is, they [[spawn (biology)|spawn]] in open water during the austral spring, releasing a large number of tiny (1&nbsp;mm in diameter), smooth spherical [[egg (biology)|eggs]] made buoyant by [[lipid]] droplets. The eggs (and later the [[larva]]e), which possess an unsegmented [[yolk]], become part of the [[zooplankton]], drifting at the mercy of the currents until the larvae develop and settle. The young Australian salmon then spend the first two to five years in sheltered coastal bays, inlets, and estuaries until they become sexually mature and begin to move into more open waters. Relatively long-lived fishes, Australian salmon may attain an age of 26 yr in ''Arripis trutta'' and 7–9 yr in other species.

All species are oceanic spawners. Reports of ''A. trutta'' being [[anadromous]] and spawning in freshwater are not correct; this may be due to confusion with sea-run specimens of exotic [[brown trout]], (''Salmo trutta''), or anadromous populations of native [[spotted galaxias]], (''Galaxias truttaceus'').

''A. georgianus'' is thought – due to females retaining both ripe and unripe eggs – to be "partial spawners"; that is, they may spawn over a long period with no real peaks. In contrast, ''A. trutta'' and ''A. truttaceus'' are thought to be "serial batch spawners", completing their spawning season after a series of small "burst" spawnings.
