Galaxiid is a genus of freshwater fish. Representatives occur throughout the southern hemisphere, including South Africa, South America, New Zealand, Australia, Lord Howe Island, New Caledonia and the Falkland Islands. Atlantic herring, Clupea harengus, the most abundant fish species in the world. ... South America South America is a continent crossed by the equator, with most of its area in the Southern Hemisphere. ... Lord Howe Island showing Mts Lidgbird and Gower. ...


Some Galaxiids live in freshwater all their lives but many involve a marine cycle for the formation of their juveniles whereby larvae are hatched in a river but are washed downstream to the ocean where they develop and return to rivers as juveniles and further develop and remain as adults.

Fishing

The juveniles of those galaxiid that develop in the ocean and then move into rivers for their adult life are caught as whitebait while moving upstream and are much valued as a delicacy. Whitebait are young fish; in Europe the term applies to young herring, but in other parts of the world it is used for similar fish of other species. ...


Adult galaxiids may be caught for food but they are generally not large and their exploitation is usually controlled (Australia) or banned (New Zealand) unless available to indigenous tribes. The word indigenous is derived from the latin word indigena, meaning nativ, indigenous, aboriginal, and has several, related meanings: The native people of a place; see the article indigenous people. ...


Australian Galaxiid

Galaxiid are found around the south eastern seaboard of Australia and in some parts of south western Australia. Species that are common to all areas are:

  • Galaxias maculatus (Jollytail galaxias) (Common galaxias) (see also Inanga)
  • Galaxias truttaceus (mountain trout) (spotted minnow)
  • Galaxias olidus (Mountain Galaxias) (Victoria)

Threatened species are: Inanga is a musical instrument in Africa akin to a zither Inanga is a member of the galaxiid genus of fish which occurs in the Southern Hemisphere Inanga is a place in Nyanga province, Gabon ...

  • Galaxias fuscus (Barred Galaxias) (Victoria)

Tasmanian Galaxiid

15 species of Galaxiid have been found in Tasmania. The most common species are:

  • Galaxias parvus (Swamp galaxias)
  • Galaxias auratus (Golden galaxias)
  • Galaxiella pusilla (Dwarf galaxias)
  • Galaxias johnstoni (Clarence galaxias)
  • Paragalaxias julianus (Western paragalaxias)
  • Paragalaxias eleotroides (Great Lake paragalaxias)
  • Paragalaxias mesotes (Arthurs paragalaxias)
  • Paragalaxias dissimilis (Shannon paragalaxias)

New Zealand Galaxiid

19 species of galaxiid have been discovered in New Zealand. Most of these live in freshwater all their lives. However, the larvae of some species develop in the ocean where they form part of the plankton and return to rivers as juveniles where they develop and remain as adults.


Galaxiids in New Zealand are:

  • Galaxias alepidotus (Giant Kokopu)
  • Galaxias argenteus (Giant Kokopu)
  • Galaxias attenuatus (Inanga)
  • Galaxias brevipinnis (Climbing galaxias) (also known as Koaro)
  • Galaxias depressiceps (Flathead galaxias)
  • Galaxias fasciatus (Banded Kokopu )
  • Galaxias graciliis (Dwarf Inanga)
  • Galaxias maculatus (Inanga) (Jollytail, also known as Common Jollytail)
  • Galaxias paucispondylus (Alpine galaxias)
  • Galaxias postvectis (Short-jawed Kokopu)
  • Galaxias vulgaris (Canterbury galaxias),
  • Neochanna apoda (mudfish)
  • Neochanna diversus (mudfish)
  • Neochanna burrowsius (mudfish)

MERG Research- Whitebait (924 words)
Diadromous galaxiids are ideal models for these techniques because the individual rivers in which they originate have distinctive chemical composition, due to historical land use practices such as mining and agriculture, which is encoded within the elemental fingerprints of otoliths.
Galaxiid larvae are also relatively large (7 - 9 mm) when they enter the marine environment, and they too should be capable of maintaining a nearshore distribution.
The Galaxiids are the southern hemisphere's equivalent of salmon.
