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...

Artificial diets have been reported to produce suboptimal pH values in the stomach of salmonid species. Therefore, it is interesting to investigate the gastric function of different species fed commercial diets. In the present work, two groups of Atlantic salmon juveniles were either fasted or fe...

Whole lupin seed meal was evaluated as partial replacement for fishmeal in extruded diets for rainbow trout, with particular emphasis on the effect on growth performance and apparent digestibility coefficient (ADC) of protein, lipids, carbohydrates, and energy. Effect on muscle fatty acid composi...
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...

En este trabajo se evalúa el efecto de una dieta pelletizada y una extruída en el crecimiento, ganancia en peso, índice de
conversión (considerando el peso total, el peso eviscerado y el peso eviscerado sin cabeza) y deposición de lípidos (carcasa,
músculo y visceras) de la trucha arcoiris. Los p...
In this paper is evaluated the effect of a pelleted diet and a extruded diet, on the growth rate, weight gain, food conversion
(considering the total weight, the eviscerated weight and the without head and viscera weight) and lipids deposition in
carcass, muscle and vicera in rainbow trout. Fish ...

This study evaluated the effects of sparteine, a lupin alkaloid, on growth and organ histology in rainbow trout. Eight diets with increasing concentrations of sparteine (0, 50, 100, 250, 500, 1000, 2500 and 5000mgkg-1) were fed to triplicate groups of 61-g fish for 62days. Survival was not affect...

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...

The effect of autoclaving on the nutrients’ apparent digestibility coefficient (ADC), digestible protein and energy of pea seed meal (P. sativum) fed to Rainbow trout (O. mykiss) was examined. Two samples of the pea meal were autoclaved at 121ºC and 1.1 atm for 5 min (5’APM) or 15 min (15’APM), r...
