Spawning does not occur beyond the river estuaries, making this species ‘only marginally catadromous’ Ref. X Close Image credit.
Hatching occurs during subsequent floods.

This information is awaiting authentication by a species expert, and will be updated as soon as possible.
Estuarine geomorphology and low salinity requirement for fertilisation influence spawning site location in the diadromous fish, Galaxias maculatus.
The sexes are separate and fertilisation is external.

Retrieved 30 August Maximum size 19 cm TL; usually to around cm TL. Sounds Ciguatera Speed Swim. Separating natural responses from experimental artefacts: A ‘boom bust’ strategy whereby spawning occurs in one event and is followed by death, semelparityor spawning over multiple events before death iteroparity. No opportunities exist for the exchange of larvae from these sink populations with other populations.
Marine and Freshwater Research 60 9: Marine and Freshwater Research Predation, macultaus and habitat-specific survival of terrestrial eggs of a diadromous fish, Galaxias maculatus Jenyns, Galaxjas species are, in general, threatened by human activities such as intensive agriculture and land change use. Size Maximum size 19 cm TL; usually to around cm TL Colour Body a translucent grey-olive to amber, with irregular greenish-grey blotches or spots on back and upper sides, belly, gill covers and eyes a bright silvery-olive to silvery-white, fins largely unpigmented.
IUCN Red List of Threatened Species
Adult inanga are the smallest of the five whitebait species, rarely exceeding mm in length. Egg mortality occurs from excess exposure to sunlight, predation from mice and spiders, grazing and trampling by livestock, mowing of bankside vegetation in urban areas, and flooding.
Retrieved 8 August Voluntary emersion behaviour and physiological adaptations to aerial exposure in a non-aestivating freshwater fish in response to aquatic hypoxia. Occur in a wide variety of habitat, but mostly in still or slow-flowing waters, mainly in streams, rivers and lakes within a short distance of the sea.
The increased nutrient input into streams from farming can lead to eutrophication.
Common Galaxias, Galaxias maculatus Jenyns More Info Distribution Galaxias maculatu s has one of the world’s largest natural distributions for a freshwater fish. Fishes of the Murray-Darling Basin: Smelt frequent similar habitat to galaxjas and can be confused with them. They tend to be found in lower-elevation streams as unlike other species of Galaxias they cannot climb past waterfalls.
