| La boutargue est constituée par les ovaires salés et séchés des mulets à grosse tête (Mugil cephalus) et de la courbine (Argyrosomus regius) représente une ressource importante pour la région de Nouakchott et pour la Mauritanie. Pour déterminer la valeur énergétique dans les boutargues, nous avons effectué des dosages des protéines, des glucides, des lipides et des études analytiques des acides gras et des lipides. Les analyses ont révélé que la boutargue contient, par rapport aux autres éléments d’énergie, très peu de glucide : 3,29% dans la boutargue du mulet et 1,95% dans celle de la courbine. Alors que les teneurs en protéines et lipides sont importantes et sont respectivement de 44,44% et 31,68% dans la boutargue du mulet et de 55,11% et 15,86% dans... |

| The species, like other members of the Family Sparidae, has a hermaphroditic phase in its sexual development, affecting the population partially during the first period of life. The sexual differentiation mechanisms have been inferred by the way of macroscopic characterization and proportionality of the different stages observed during the first five year classes. The highest proportion of specimens with bisexual gonads is observed during the third year of life: from the macroscopical point of view, both sexes are equally developed or with predominance of the masculine crest; microscopically, both are functional and synchronous. The masculine portion demostrate a normal expulsion of germ cells and in the ovaric part post-ovulatory and atretic follicles... |

| Batch fecundity and spawning frequency of Argentine hake inhabiting Patagonian waters south of 41° S were estimated using monthly samples collected during the December 2000-March 2001 reproductive season and at the end of the March 2002 spawning period. Batch fecundity was fitted to a power function of total length and a linear function of ovary-free female weight with values ranging between 100,000 (32 cm total length) and 2,300,000 (87 cm total length) hydrated oocytes. Batch and relative fecundity showed variations during the spawning season with a marked decrease towards the end of the reproductive period (March). The spawning frequency, which ranged between 0.10 and 0.15, was estimated from the proportion of females with day-1 postovulatory follicles... |
