| El presente estudio tiene como objetivo evaluar el stock de merluza de tres aletas (Micromesistius australis) a través del método hidroacústico, entre las latitudes 47º y 51º S. Como parte del proyecto se realizó entre el 13 y el 22 de agosto de 2005 a bordo del B/F Unzen un crucero de prospección orientado a evaluar mediante un método de evaluación directa (evaluación acústica) su biomasa, abundancia y distribución, estimar la importancia relativa de la fauna acompañante, condiciones reproductivas y tróficas del stock y realizar un análisis de las agregaciones detectadas durante el crucero. Durante el estudio se realizaron 41 lances de pesca de reconocimiento (23 positivos) y 49 transectas acústicas. |

| We examined the effects of diet composition and fasting on lipolysis of freshly isolated adipocytes from gilthead seabream (Sparus aurata). We also analyzed the effects of insulin, glucagon, and growth hormone (GH) in adipocytes isolated from fish fed with different diets. Basal lipolysis, measured as glycerol release, increased proportionally with cell concentration and time of incubation, which validates the suitability of these cell preparations for the study of hormonal regulation of this metabolic process. Gilthead seabream were fed two different diets, FM (100% of fish meal) and PP (100% of plant protein supplied by plant sources) for 6 wk. After this period, each diet group was divided into two groups: fed and fasted (for 11 days). Lipolysis was... |
