RESUMEN: Se provee una descripción morfológica y morfométrica del desarrollo larval de Prochilodus magdalenae, del río Magdalena, Colombia. Los especímenes fueron obtenidos por desove inducido. Esta especie presenta huevos libres y muy hidratados. El período de incubación es corto y duró aproximadamente 14 h después de la fertilización a 24 oC. La larva no está bien desarrollada al momento de la eclosión, con período larval relativamente rápido y metamorfosis acentuada. El análisis de los datos morfométricos mostró que algunas de las partes corporales de P. magdalenae no crecen proporcionalmente.
ABSTRACT: Morphological and morphometric descriptions of the larval development of Prochilodus magdalenae, from the Magdalena river, Colombia are provided. Specimens were obtained by induced spawning. This species produces very hydrated free eggs. The incubation period was short; it lasted 14 hours at 24 oC after fertilization. Larvae are slightly developed at hatching, with relatively rapid larval development and an accentuated metamorphosis. Analysis of the morphometric data showed that some parts of the body of P. magdalenae do not grow proportionally.
