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 ...

Summary Reproductive aspects of a peripheral population of Galaxias maculatus are described and the relationship with the physiology and handling of energetic reserves under marginal environmental conditions is investigated. The G. maculatus population of Tierra del Fuego has an extended reproductive season, with differences in timing and duration ...

Seventeen novel microsatellite markers for the southern hemisphere fish Galaxias maculatus
Conservation Genetics Resources, 2014Galaxias maculatus is a widely distributed fish with diadromous and resident populations throughout Gondwanan regions. We present 17 novel microsatellite markers that were tested on 44 individuals from one lacustrine population in Patagonia. We found ten poly- morphic markers and seven monomorphic markers in the population under analysis. The number of

Impact of a Caged-Trout Farm on Parasites of Galaxias maculatus in Lake Moreno, Southern Argentina
Journal of Parasitology, 2005The present study was conducted to determine the impact of a caged-trout farm on the helminth parasites of the wild fish puyen chico (Galaxias maculatus) in Lake Moreno, southern Argentina. Samples of water, fish (G. maculatus), and snails (Heleobia hatcheri) were taken at 4 sampling stations in January 2001.

Protected areas (PAs) have become the cornerstone management strategy for terrestrial and increasingly marine biodiversity conservation, yet freshwater protected areas (FPAs or freshwater reserves) remain rare. This is surprising considering that freshwater ecosystems, and the biodiversity they support, are among the most threatened worldwide.

The physiological challenges incurred during the transition from sea to fresh water and the constraints they place on the rate at which the common galaxiid Galaxias maculatus and the climbing galaxiid Galaxias brevipinnis can migrate from marine to freshwater habitats were examined.

Migration of galaxias maculatus (Jenyns) (galaxiidae, pisces) in Valdivia Estuary, Chile
Hydrobiologia, 1973A migratory pattern ofG. maculatus as a diadromic and marginally catadromic, is similar to that in New Zealand and Australia. Their migratory relationship with the sea suggests that their route of dispersal in the tertiary might have been transantartic (western Antartica) and not caused by the “West Wind Drift” as suggested by other authors.

Acute toxicity of ammonia to juvenile inanga (Galaxias maculatus)
New Zealand Journal of Marine and Freshwater Research, 1991The toxic concentration of unionised ammonia (NH 3 ) was assessed for juvenile Galaxias maculatus by running a 96 h LC50 test. The 96 h LC50 concentration at 15°C and pH ≥ 8 was 1.60 mg NH 3 1 −
