Mechanisms of zinc toxicity in the galaxiid fish, Galaxias maculatus
Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2016Zinc (Zn) is an essential metal, which is ubiquitous in aquatic environments occurring both naturally, and through anthropogenic inputs. This study investigated impacts of sub-lethal Zn exposure in the galaxiid fish Galaxias maculatus. Known as inanga, this amphidromous fish is widespread throughout the Southern hemisphere, but to date almost nothing ...

A novel oxyconforming response in the freshwater fish Galaxias maculatus
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2012How fish oxygen consumption is modulated by external PO(2) has long been a matter of interest, yet is an experimentally complicated question to answer. In this study closed and semi-closed respirometry were used to evaluate the oxygen consumption rate of the scaleless galaxiid fish, inanga (Galaxias maculatus) as a function of decreasing external PO(2).

Galaxias maculatus : An explanation of its biogeography
Marine and Freshwater Research, 1996Galaxias maculatus is a small diadromous fish found in Australia, New Zealand, South America and on some oceanic islands. Two hypotheses have been advanced to explain this widespread, disjunct distribution. McDowall promoted dispersal through the sea of salt-tolerant juveniles but Rosen and others claimed that the distribution reflected the break-up of

Phenotypic and genetic differentiation between diadromous and landlocked puyen
AbstractThis study reports the phenotypic and genetic differences between individuals of puyen Galaxias maculatus from two sites in the same river basin in Tierra del Fuego National Park, southern South America. Individuals from the two sampling sites presented morphometric and genetic differences.

Salinity-dependent mechanisms of copper toxicity in the galaxiid fish, Galaxias maculatus
Aquatic Toxicology, 2016The euryhaline galaxiid fish, inanga (Galaxias maculatus) is widely spread throughout the Southern hemisphere occupying near-coastal streams that may be elevated in trace elements such as copper (Cu). Despite this, nothing is known regarding their sensitivity to Cu contamination.

Metazoan Parasites of Galaxias maculatus (Osmeriformes: Galaxiidae) from Argentinean Patagonia
Comparative Parasitology, 2009A checklist, based on bibliographical records and original data from an extensive survey, is presented for the metazoan parasites of Galaxias maculatus (Jenyns, 1842) in Argentinean Patagonia. The checklist includes 33 metazoan parasite entries: 5 myxozoans, 12 digeneans, 2 monogeneans, 3 cestodes, 2 acanthocephalans, 7 nematodes, 1 copepod, and 1 ...

Laboratory culture of Galaxias maculatus and potential applications
New Zealand Journal of Marine and Freshwater Research, 1989Galaxias maculatus has considerable potential as a laboratory animal. Laboratory techniques used to maintain, artificially spawn, hatch, and rear this New Zealand native freshwater fish are described. Potential research applications for the fish, the eggs, and the larvae are outlined.

Variation of the use of marine resources by Galaxias maculatus in large Chilean rivers
Hydrobiologia, 2015The objective of this study was to assess the frequency of use of marine resources in recruitment of Southern Hemisphere native riverine fish Galaxias maculatus from rivers across a latitudinal gradient. To do this, we analysed the concentrations of δ34S in vertebral column tissues from fish collected in ten Chilean river systems across latitudes 36 ...
