dc.description.abstractEnglish - A study was carried out to document the current status of the Devil's River Minnow, Dionda diaboli Hubbs and Brown, 1956, in northern Coahuila, Mexico. Three field trips were carried out with a total of 49 localities sampled, documenting presence of 49 species of the 54 species previously registered in the area, which are from 25 genera and 12 families. Six localities were previously known for this species in Mexico, and those historical records were obtained and entered into a geographic information system. The Devil's River Minnow was found in only one of the historic locations, in the Río San Juan under the bridge on the Múzquiz - Boquillas del Carmen highway, Múzquiz, Coahuila. Habitat condition, water quality, aquatic vegetation of all historic locations, as well as an analysis of the fish community, were evaluated. We observed that temperature oscillates between 23.9 and 27.8 ºC, the salinity between 0.14 and 0.17 ppm, the dissolved oxygen between 64.9 and 90%, the pH between 7.14 and 8.03, the turbidity below 30, with little organic matter, as shown by the results for nitrites, nitrates, sulfates, calcium and magnesium. It was found that the causes of the disappearance of Dionda diaboli, in the other localities, is due to the presence of exotic species, alteration of the habitat, decrease in water level and runoff, siltation by sediments and probably due to changes in the trophic structure of the fish community. Spanish - Se realizó un estudio para conocer el estado actual de la carpa diabla, Dionda diaboli Hubbs y Brown, 1956, de la región Norte del Estado de Coahuila, México. Se efectuaron 3 salidas de campo con un total de 49 localidades visitadas, de las cuales se reportan 49 especies de las 54 registradas en la zona, repartidos en 25 géneros y 12 familias. Seis localidades son registradas de esta especie en México, con los registros obtenidos y los registros históricos se elaboró un sistema de información geográfica. Solo fue posible observar a la carpa diabla en una de las localidades históricas. En Río San Juan bajo puente, carretera Múzquiz – Boquillas del Carmen. Múzquiz, Coahuila. Se evaluó la condición de hábitat, calidad de agua, vegetación acuática de las localidades históricas así como un análisis de la comunidad de peces. Entre los parámetros ambientales observamos que la temperatura oscila entre 23.9 y 27.8 ºC, la salinidad entre 0.14 y 0.17 ppm, el oxigeno disuelto entre 64.9 y 90 %, el pH entre 7.14 a 8.03, la turbidez inferior a 30, con escasa materia orgánica, como lo muestran los resultados de nitritos, nitratos, sulfatos, calcio y magnesio. Se encontró que las causas de desaparición del Dionda diaboli, en las otras localidades se debe a la presencia de especies exóticas, alteración del hábitat, disminución del nivel de agua y escorrentía, asolvamiento por sedimentos y probablemente por los cambios en la estructura trófica de la comunidad íctica.en_US
