Fish swimming speed variability at constant flow:Galaxias maculatus
New Zealand Journal of Marine and Freshwater Research, 2007Abstract Digital videography was used to study the swimming performance of the adult fish Galaxias maculatus in a flume at fixed flows. Instantaneous fish swimming velocities varied about the mean flume velocity and these variations in swimming speed were found to increase as velocity in the flume increased.

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

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.

Laboratory culture ofGalaxias maculatusand potential applications
New Zealand Journal of Marine and Freshwater Research, 1989Abstract Galaxias 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. The development of the larvae is described.

SummaryThe salinity tolerance and osmoregulatory ability of Galaxias maculatus were investigated. In the field this species has been recorded from salinities of less than 1‰ to 49‰. In the laboratory, upper L.D.50 salinity values of 62‰ after gradual acclimation and 45‰ after direct transfer were established.

Morphology and Ultrastructure of Puye (Galaxias maculatus) Spermatozoa
Acta ZoologicaABSTRACTThis study characterises basic seminal and sperm parameters of puye (Galaxias maculatus maculatus), including sperm concentration, seminal plasma osmolality and cell viability. In addition, it provides a detailed description of sperm ultrastructure. Wild males (n = 21) were captured in southern Chile.

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.

AbstractTen polymorphic microsatellite markers (five tetra‐, one compound tetra‐, one octa‐ and three dinucleotides) were isolated and characterized for Galaxias maculatus, a fish species widely distributed in the Southern Hemisphere. Markers were tested in 89 individual samples from a single location and the number of alleles ranged between 2 and 28 ...
