ABSTRACT
Organogenesis of the digestive system of the fish Pterophylum scalare (Perciformes Cichlidae). There is little knowledge on the development of the angelfish Pterophyllum scalare (Liechtenstein 1823), a species of economical and biological value for inland water ecosystems. We recorded net development time of each organogenetic stage, cumulative time and characteristic structure differentiation for each stage. We found eight organogenetic stages for the digestive system, between the gastrula and the total re-adsorption of the vitelin sack. The total time for the organogenetic development of the digestive system was 119 hours and 44 minutes. Rev. Biol. Trop. 56 (4) 1857-1870. Epub 2008 December 12.
RESUMEN
Debido a la poca información sobre el desarrollo de sistemas orgánicos en el pez Pterophylum scalare (Liechtenstein 1823) estudiamos yiempo neto de desarrollo de cada estadio de la organogénesis, tiempo acumulado y diferenciación de estructuras características de cada estadio. Se obtuvo un total de 8 estadios en la organogénesis del sistema digestivo, comprendidos entre la gástrula y la reabsorción total del saco vitelino. La duración de la organogénesis del sistema digestivo fue de 119 horas 44 minutos.
