Influencia de factores bióticos y abióticos sobre las comunidades de parásitos metazoos de un pez presa nativo: estudio en 28 lagos andino patagónicos

Ecología Austral, 2015
Galaxias maculatus (puyen chico) es una especie de pez presa que tiene un rol importante en las redes tróficas de los lagos de la Patagonia. Estudios previos, a escala local, muestran que la riqueza y la composición de las comunidades componentes de ...

Egg cannibalism by inanga ( Galaxias maculatus ) [PDF]

New Zealand Journal of Marine and Freshwater Research, 2003
Abstract Egg cannibalism by inanga ( Galaxias maculatus ) was found to occur immediately after spawning. Spent and immature inanga from a school of 335 fish consumed between 0 and 51 eggs each.

Infections by Helminth Parasites in "Puyenes", Galaxias maculatus (Galaxiidae, Salmoniformes), from Southern Argentina with special reference to Tylodelphys barilochensis (Digenea, Platyhelminthes)

Memorias do Instituto Oswaldo Cruz, 1999
The occurrence of Tylodelphys barilochensis, Acanthostomoides apophalliformis, Contracaecum sp. and Camallanus corderoi infecting Galaxias maculatus ("puyenes") was quantified for the first time in Lake Nahuel Huapi, southern Argentina. T.

Distribution of the spotted minnow (Galaxias maculatus (Jenyns, 1842)) (Teleostei: Galaxiidae) in Western Australia including range extensions and sympatric species

, 2006
Galaxias maculatus was captured from a number of rivers outside its previously known range. In Western Australia, it was formerly only known from rivers and lakes between the Goodga River (Two People's Bay, 30 km east of Albany) and the Dailey River (50 ...

Assessment of Heavy Metal Contamination in Two Edible Fish Species and Water from North Patagonia Estuary

Applied Sciences, 2021
Estuaries worldwide have been severely degraded and become reservoirs for many types of pollutants, such as heavy metals. This study investigated the levels of Cd, Cu, Mn, Ni, Pb, and Zn in water and whole fish.

Attraction of migratory inanga (galaxias maculatus) and koaro (galaxias brevipinnis) juveniles to adult galaxiid odours

, 2003
The response of migratory galaxiid juveniles, inanga (Galaxias maculatus) and koaro (G. brevipinnis), to the odours of adult galaxiids was tested in a two-choice chamber apparatus. Both conspecific and heterospecific odours were tested. Inanga juveniles

A Global Assessment of Parasite Diversity in Galaxiid Fishes

Diversity, 2021
Free-living species often receive greater conservation attention than the parasites they support, with parasite conservation often being hindered by a lack of parasite biodiversity knowledge.

Assessment of histological changes caused by the trematode Tylodelphys sp. in the central nervous system of Galaxias maculatus [PDF]

Neotropical Ichthyology
A recent experimental study has reported significant changes in the behaviour of the fish Galaxias maculatus due to the presence of the parasite trematode Tylodelphys sp. in its cranial cavity.

Latitudinal variation of migratory life histories of riverine Galaxias maculatus in Chile (36°- 47°S)

Frontiers in Marine Science, 2015
A relationship between life histories and increasing latitude has been described for Northern Hemisphere riverine fish, whereby life cycles that complete most of the growth in the ocean are favoured at higher latitudes.

Deposition of Galaxias fasciatus eggs with Galaxias maculatus eggs at a tidal site [PDF]

New Zealand Journal of Marine and Freshwater Research, 1991
While measuring egg distribution of the intertidally spawning galaxiid fish, Galaxias maculatus , some noticeably larger eggs (1.86–2.2 mm diam.) were seen. In common with the smaller G. maculatus eggs (1.18–1.5 mm diam.), these eggs peaked in abundance
