Fotoperiodo y ontogenia inicial de peces migratorios en Brasil con énfasis en sábalo (Prochilodus lineatus) ; Photoperiod and initial ontogeny of migratory fish in Brazil with special emphasis on sabalo (Prochilodus lineatus)
The study of reproductive aspects and ontogeny of migratory fish is relevant in pisciculture, especially when it is related to native species, emphasizing the patterns of growth and development of these taxa. The present research aimed to make a compilation of current knowledge on the ontogeny of sabalo, Prochilodus lineatus, in embryonic and larval stages, under varying photic environments and the adaptive capacity of the phenotype. Besides, the cases of other species currently cultivated or potentially productive in this stages were reviewed. Thus, the manipulation of light and darkness regi... Mehr ...

The study of reproductive aspects and ontogeny of migratory fish is relevant in pisciculture, especially when it is related to native species, emphasizing the patterns of growth and development of these taxa. The present research aimed to make a compilation of current knowledge on the ontogeny of sabalo, Prochilodus lineatus, in embryonic and larval stages, under varying photic environments and the adaptive capacity of the phenotype. Besides, the cases of other species currently cultivated or potentially productive in this stages were reviewed. Thus, the manipulation of light and darkness regimes has allowed to move forward or backwards the onset of reproduction and improve growth rates, as well as the embryonic and larval development in fish. Nevertheless, data is dispersed and in some cases there are information gaps, especially on migratory fish species in Brazil, including the sabalo. In this compilation, the modulating action of some environmental factors such as photoperiod, which can be manipulated to improve the production of sabalo in the early stages of its life cycle is highlighted. By the nature of these factors, efforts should be addressed from the perspective of adaptation or phenotypic plasticity of the studied biological model. ; El estudio de los aspectos reproductivos y de la ontogenia de los peces migradores es de gran importancia en piscicultura, especialmente cuando se trata de especies nativas, resaltándose los patrones de crecimiento y desarrollo. El objetivo delpresentetrabajofuehacer unacompilación delconocimientoactualdelaontogenia de sábalo, Prochilodus lineatus, en las fases de embrión y larva, bajo ambientes fóticos variables y desde la perspectiva de la capacidad adaptativa del fenotipo. Además, se revisaron casos de otras especies bajo cultivo o con potencial productivo. De este modo, la utilización de los cambios en los regímenes de luz y oscuridad han permitidoacelerar oretrasar lareproducción ylastasas decrecimiento,asícomo el desarrollo embrionario y larval en peces.
