Resumen:
The pejerrey fish (Odontesthes bonariensis), a large atherinid native from the inland waters of Buenos Aires Province, is considered one of the most emblematic fresh water fish  species of Argentina (López et al., 2001). Although it is an important commercial and game fish, its culture has not been well developed in Argentina. Besides, some reports have demonstrated the existence of problems in intensive pejerrey aquaculture: early sexual maturation, the presence of spawning asynchrony between females and low growth rates (Strüssmann, 1989; Strüssmann et al., 1993). During the last years the interest of the laboratory has been focussed on the study of the reproductive physiology and the mechanisms involved during sexual determination/differentiation in pejerrey, not only from a basic point of view but also keeping attention to the potential application of the knowledge on the development of pejerrey aquaculture. In this context, the goal of the present work was to summarize the findings on the characterization of the brain-pituitary-gonadal axis in Odontesthes bonariensis.
