	abstract = {La trucha Yaqui pertenece a un grupo de truchas nativas no descritas del g{\'e}nero Oncorhynchus del Noroeste de M{\'e}xico. Estudios morfol{\'o}gicos y moleculares postulan a la trucha Yaqui como una nueva especie exclusiva para las cuencas de los r{\'\i}os Yaqui, Mayo y Casas Grandes y, evolutivamente muy cercana a la trucha arco{\'\i}ris, Oncorhynchus mykiss. El conocimiento de su historia natural es escaso. Se estudi{\'o} la variabilidad gen{\'e}tica poblacional y su estatus de conservaci{\'o}n en su distribuci{\'o}n en Sonora en la regi{\'o}n de Mesa Tres R{\'\i}os. Se muestrearon seis arroyos de aguas fr{\'\i}as (localidades) en la regi{\'o}n de Mesa Tres R{\'\i}os en dos vertientes geogr{\'a}ficas en la b{\'u}squeda de estructura gen{\'e}tica poblacional. Se analizaron 61 secuencias completas de la regi{\'o}n control del ADN mitocondrial. Se obtuvieron nueve haplotipos, tres de ellos se encontraron en ambas vertientes de las localidades del {\'a}rea estudiada. Los resultados mostraron una baja diferenciaci{\'o}n gen{\'e}tica poblacional (Fst = 0.08035) y un moderado n{\'u}mero de migrantes por generaci{\'o}n (Nem = 5.72), que resulta en una falta de estructura poblacional y sustenta la hip{\'o}tesis de una sola poblaci{\'o}n de trucha Yaqui en las vertientes muestreadas de la regi{\'o}n de Mesa Tres R{\'\i}os, Sonora.Yaqui trout belongs to a group of undescribed native trouts of the Oncorhynchus genus in the Northwest Mexico. Morphological  and  molecular  studies  postulate  the  Yaqui  trout as a new species exclusively inhabiting the Yaqui, Mayo and Casas Grandes rivers basins, and with a very close evolu-tionary relationship to the rainbow trout, Oncorhynchus my-kiss. Knowledge of its natural history is scarce. We studied the population genetic variability and its conservation status in its distribution in Sonora in the Mesa Tres R{\'\i}os region. Six cold water streams (localities) were sampled in the Mesa Tres R{\'\i}os region in two geographic slopes in the search for population genetic  structure.  We  analyzed  61  complete  sequences  of  the mitochondrial DNA control region. Nine haplotypes were obtained, three of them found in both slopes of the localities in the studied area. Results showed a low population genetic differentiation  (Fst  =  0.08035),  and  a  moderate  number  of  migrants per generation (Nem = 5.72), which results in a lack of  population  structure,  and  supports  the  hypothesis  of  a  single  population  of  Yaqui  trout  in  the  sampled  watersheds  from the Mesa Tres R{\'\i}os region, Sonora.Keywords:  Control  region,  Genetic  structure,  Yaqui  trout,  Northwest Mexico
