Muscle myogens in the New Zealand Galaxiidae

New Zealand Journal of Marine and Freshwater Research, 1979
The muscle myogen proteins of 10 species of the family Galaxiidae exhibited a high degree of species specificity when separated by starch gel electrophoresis. Non‐diadromous, non‐lacustrine species had some variation in the proteins present, while diadromous and lacustrine species, except for Galaxias maculatus

Provenance and status of Galaxias smithii Regan (1905) (Teleostei: Galaxiidae)

Journal of Natural History, 2002
Galaxias smithii (Regan, 1905) (a junior synonym of G. platei Steindachner) is known only from the holotype, ostensibly collected from the Falkland Islands by Sir A. Smith. No further specimens of this fish have been reported from the islands, despite a recent intensive collection trip (146 sites in November, 1999).

Adaptative Radiation of the Retina in Galaxiidae (Salmoniformes)

Australian Journal of Zoology, 1990
The retinas of seven galaxiid species collected from different habitats in Tasmania were investigated by light microscopy. There are remarkable differences between Galaxias and Paragalaxias species. The retinas of Galaxias species are characterised by a less dense retinal epithelial pigment (REP), large numbers of short and long rods, the presence of a

A revision of the family Galaxiidae (Pisces) in Tasmania

Marine and Freshwater Research, 1976
Nine species of the genus Galaxias and one species of the genus Paragalaxias are found to be represented in Tasmania. The taxonomy, meristic and morphometric variation of each species is examined and data on the distribution, life history and ecology are presented together with references and synonymy.

Cytotaxonomy of seven species of Galaxias (Pisces: Galaxiidae) in Tasmania

Genetica, 1981
Karyotypes of 7 species of the genus Galaxias in Tasmania are compared and a phylogenetic interpretation of these data offered. Species fall into 3 distinct groups, viz. those with 2n=44 (G. brevipinnis, G. johnstoni and G. fontanus), those with 2n=32 (G. truttaceus, G. tanycephalus and G. auratus), and G. maculatus with 2n=22.

Molecular phylogeny and biogeography of the Tasmanian and New Zealand mudfishes (Salmoniformes : Galaxiidae)

Australian Journal of Zoology, 1997
The phylogenetic affinities of the diadromous Tasmanian mudfish, Galaxias cleaveri , have long been problematic. Some systematists have suggested that this species is closely related to the morphologically similar but non-diadromous New Zealand mudfish genus, Neochanna , while others argued that the similarities represent convergent evolution.

Spawning of Galaxias fasciatus Gray (Salmoniformes: Galaxiidae)

New Zealand Journal of Marine and Freshwater Research, 1982
Abstract For the first time Galaxias fasciatus Gray were observed spawning. The spawning sites were among flooded terrestrial vegetation along the margins of a stream during the peak of a flood. Spawning appeared to be a communal event and the fish were vulnerable to eel

A revision of the Genus Galaxias : (Pisces: Galaxiidae) in Tasmania

1973
Eight species of the genus Galaxias are found to be represented in Tasmania. The taxonomy, meristic and morphometric variation of each species is examined and data on the distribution, life history and ecology of each species are presented together with references and synonomy. Excluding the two genera Paragalaxias and Brachygalaxias, which are outside
