Galaxias maculatus (Jenyns, 1842) es un pez gourmet de importancia comercial cuyas pesquerías están sobre-explotadas, siendo esencial el estudio de su biología para desarrollar su tecnología de cultivo (galaxicultura), que se encuentra en etapa piloto. Los objetivos de éste trabajo son: 1) entreg...

Galaxias maculatus (Jenyns, 1842), is a gourmet fish of great commercial importance with overexploited fisheries. So, studies of its biology are essential in order to develop a technology for its cultivation (galaxiculture), which is at a pilot stage. The goals of this work are: 1) to provide a s...

Galaxias maculatus eggs and larvae obtained from broodfish captured either in an estuarine or a freshwater environment, as well as from cultured broodstock were analysed to compare their lipid and fatty acid profiles. Results showed a lower lipid content in embryos and larvae from estuarine popul...

Este estudio muestra los antecedentes del cultivo larvario del puye, Galaxias maculatus (Jenyns), un pequeño pez de aguas frías del hemisferio sur. Para el cultivo, larvas recién eclosionadas fueron puestas en estanques de 500 litros de volumen útil. Las larvas fueron alimentadas utilizando una s...

This study reports data on the larval culture of the "puye", Galaxies maculatus (Jenyns), a small cold water fish occurring in the Southern Hemisphere. For this culture, recently enclosed larvae were placed into 500 liter tanks and fed first with rotifers, then with Artemia spp., and finally with...

Despite the well known importance of omega-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. The present study aimed to determine the ...

Despite the importance of certain highly unsaturated fatty acids in osmotic regulation, few studies have been addressed to determine the essential fatty acid requirements for a given species cultured under different salinities. As Galaxias maculatus is a diadromic species, the present study aimed...
