Downstream migration of telemetry-tagged adult common galaxias (Galaxias maculatus) in a coastal river system

Marine and Freshwater Research, 2023
Many migratory species are under threat globally. Management actions to conserve these species require a quantitative understanding of their life-history requirements, such as cues for migration. Migrations to spawn are a critical component of the life-cycle of diadromous fishes but are often poorly understood.

Aspects of the biology of Galaxias maculatus

Journal of Fish Biology, 2012
The biology of three landlocked and a riverine population of Galaxias maculatus were examined in western Victoria, Australia. All systems supported reproducing populations of these fish, including Lake Corangamite which had salinities that on occasion reached 82.

A novel oxyconforming response in the freshwater fish Galaxias maculatus

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2012
How 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).

Mechanisms of zinc toxicity in the galaxiid fish, Galaxias maculatus

Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2016
Zinc (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 ...

Phenotypic and genetic differentiation between diadromous and landlocked puyen Galaxias maculatus

Journal of Fish Biology, 2020
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.

Galaxias maculatus : An explanation of its biogeography

Marine and Freshwater Research, 1996
Galaxias 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

Metazoan Parasites of Galaxias maculatus (Osmeriformes: Galaxiidae) from Argentinean Patagonia

Comparative Parasitology, 2009
A 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 ...

Salinity-dependent mechanisms of copper toxicity in the galaxiid fish, Galaxias maculatus

Aquatic Toxicology, 2016
The 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.
