摘要: The aim of this study was to assess the effect two rearing conditions: outdoor environment with great volume tanks (500 m3) and low stocking density (~0.4 kg m−3); indoor smaller (10 m3) higher (~5 kg m−3), on muscle, liver ovary lipid composition Seriola dumerili broodstock born in captivity. conditions tested seem affect pattern body deposition fish S. dumerili, increasing muscle triacylglycerides (TG) accumulation kept under conditions, probably due reduced energy expenditure swimming, some variations fatty acid profile that may respond differences culture tested. No significant were found for Gonadosomatic Index (GSI) or between groups study, which suggest do not have a major development. However, one season later females released eggs spontaneously, whereas those did spawn, suggesting actually an the broodstock's reproductive fitness. More studies are needed order evaluate whether any influence
