Efecto de la temperatura en la sobrevivencia embrionaria del puye Galaxias maculatus (Jenyns, 1842)

Latin American Journal of Aquatic Research, 2013
Se evaluó el efecto de seis temperaturas constantes en la sobrevivencia embrionaria, periodo embrionario y periodo de eclosión de Galaxias maculatus de 7 a 22°C, en condiciones de laboratorio. Los resultados de la sobrevivencia embrionaria fueron: 90,6 ±

Feeding ω-3 PUFA enriched rotifers to Galaxias maculatus (Jenyns, 1842) larvae reared at different salinity conditions: effects on growth parameters, survival and fatty acids profile

Latin American Journal of Aquatic Research, 2013
Despite the well known importance of ω-3 polyunsaturated fatty acids (PUFA) in marine and freshwater fish larvae, there are few studies on how essential fatty acid requirements and composition on whole body can be altered by changes in water salinity ...

Using biotracer techniques to uncover consumer diets: A comparison of stable isotopes, fatty acids, and amino acids

Ecosphere
Biotracers are commonly used in food‐web studies to estimate consumer diets. Increasingly, multiple biotracer types are combined to provide more nuanced pictures of consumer resource use, unravel more complex diet mixtures, and improve the discriminatory

Efecto combinado de la temperatura y salinidad sobre la supervivencia embrionaria de Galaxias maculatus [PDF]

, 2015
This study aims to evaluate the effect of temperature and salinity on Galaxias maculatus embryo survival. Embryos were incubated at 5, 10 and 15°C and 0, 10 and 30 psu. At 5°C all salinities induced 100% mortality. Furthermore, salinity of 30, regardless

Embryonic survival of Galaxias maculatus (Jenyns, 1842), under different prophylactic immersion bath

, 2021
The use of antifungals was assessed to improve embryo survival of Galaxias maculatus. Three treatments using formalin dose of 250 ppm, iodine dose of 100 ppm, and sea salt in doses of 30 ups were designed, and a control treatment under 10 of salinity ...

The helminth communities structure of Galaxias maculatus (Osmeriformes: Galaxiidae) in different sites of an Argentinean Patagonian lake. [PDF]

, 2015
La variación espacial de las comunidades de helmintos en un sistema acuático puede atribuirse a diferentes factores bióticos y abióticos. En América del Sur, este tipo de estudios no se han realizado en ambientes de agua dulce. El lago Nahuel Huapi es el

Data from: Genetic and phenotypic differentiation among Galaxias maculatus populations in a Patagonian postglacial lake system

, 2012
Understanding the influence of landscape features on population differentiation is fundamental to evolutionary biology studies. We examined spatial patterns of genetic and phenotypic variability among Galaxias maculatus populations in a complex of four ...
