Resumen o descripción

"The trout species of Mexico‘s Sierra Madre Occidental (SMO) range have been essentially ignored in science except for the efforts of Needham and Gard (1959) in the mid-20th century. Even after their work documenting the existence of the Mexican Golden Trout Oncorhynchus chrysogaster no focused efforts to study the diversity in the SMO south of the USA were initiated until 1997. Sampling in the Sierra Madre Occidental is extremely difficult, but our efforts since that year have revealed that all of Mexico‘s SMO trout are native (except for hatchery-reared) to the Río Yaqui system southward to the Río Acaponeta, and in the Río Conchos drainage. Morphological and genetic studies of the populations from these rivers support the hypothesis of multiple divergent lineages that we argue are distinct evolutionary species. Conservation and protection of these lineages are critical and should constitute a coordinated effort involving governmental agencies, private organizations, nonprofit groups, and individuals. More inventory work is warranted to better understand the distributions of the native trout and efforts should be made to eliminate the introduction of ―hatchery rainbow trout‖ Oncorhynchus mykiss into grow-out facilities in these mountains, instead replaced with propagation efforts on the different native species within their respective drainages. The diversity of wildlife and natural features across the SMO could, with proper planning and maintenance, serve as a fundamental, environmentally sound, sustainable resource for the region via ecotourism."
