The utilization of the energy of food by red porgy (Pagrus pagrus Linnaeus, 1758) from the Argentine Sea (SW Atlantic) was studied. From the energetic point of view, it is proposed that the strategy of patitioning, utilization and storage of the energy of food, is an indicator of the organism response to the environmental conditions. The main objective was to know the proportion of the energy of food derived to the different components of the bioenergetics budget. In order to estimate the monthly energy investment in reproductive growth, chemical analysis of gonads from fishes caught by the fishery fleet and from laboratory studies were performed. Two indexes were used to calculate the energy investment in female ovaries: the proportion of net daily energy change in the ovaries in relation to the food consumed (effort), and the reproductive cost. During December and January, the spawning time in the broodstock tank was 16:00. Energy storage and stable periods were detected along the ye.....
