While biologists have been aware of theexistence of native Mexican trouts for over acentury, they have received little study. Thefew early studies that did much more thanmention their existence began in the 1930s andcontinued into the early 1960s, focusingprimarily on distributional surveys andtaxonomic analyses. Starting in the 1980s theBaja California rainbow trout became thesubject of more detailed studies, but verylittle remains known of mainland trouts of theSierra Madre Occidental. We… 
First steps towards the identification of evolutionarily significant units in Mexican native trout: An assessment of microsatellite variation
The results reject the old hypothesis that many of the trout in Mexico are introduced or translocated hatchery-reared rainbow trout and strongly support the new hypothesis of distinct genetic populations and lineages in the northwest of Mexico.
Genetic Structure of Pacific Trout at the Extreme Southern End of Their Native Range
Salmonid fishes are cold water piscivores with a native distribution spanning nearly the entire temperate and subarctic northern hemisphere. Trout in the genus Oncorhynchus are the most widespread

Potential distribution of endangered Mexican golden trout (Oncorhynchus chrysogaster) in the Rio Sinaloa and Rio Culiacan basins (Sierra Madre Occidental) based on landscape characterization and species distribution models
The Mexican Golden Trout (Oncorhynchus chrysogaster) is a threatened native species inhabiting three river basins in the Sierra Madre Occidental. Despite some efforts from science groups to obtain
Conservation of Native Pacific Trout Diversity in Western North America
This work focuses on Pacific trout in the genus Oncorhynchus, because they share a common evolutionary history, and many taxa in western North America have not been formally described, particularly in the southern extent of their ranges.
Rainbow Trout in Europe: Introduction, Naturalization, and Impacts
There is no consensus on the reasons for the absence of self-sustaining populations of rainbow trout across much of Europe, but knowledge of the mechanisms involved is limited, while the data collected here shed new light on the invasion biology of the species.
Greenback cutthroat trout (Oncorhynchus clarkii stomias): A technical conservation assessment
Greenback cutthroat trout (Oncorhynchus clarkii stomias) was once presumably distributed throughout the colder waters of the South Platte and Arkansas River basins in Colorado and southeastern
Riverscape genetics in the endangered Mexican golden trout (Oncorhynchus chrysogaster) in Sierra Madre Occidental, Mexico
Assessment of the possible relationships between microevolutionary processes of the Mexican golden trout, as well as the spatial structure of their habitat defining extinction risks derived by global change, revealed a significant influence of riverscape factors on the neutral and adaptive genetic structure of the species.
Effects of nonnative Rainbow Trout on two species of endemic Mexican amphibians
The authors' results provide strong circumstantial evidence that the introduction of Rainbow Trout in streams in the Sierra de Las Cruces has a negative effect on the distribution of native Mexican amphibians.
Morphometric variation of wild trout populations from northwestern Mexico (Pisces: Salmonidae)
Morphometric variation of 17 wild troutpopulations of the genus Oncorhynchusfrom northwestern Mexico was analyzed.We used 25 standardized morphometric characters following a box truss protocol. In


Classification of the Native Trouts of Arizona with the Description of a New Species, Salmo apache
It is suggested that the California golden trout was derived from an ancestor that entered the Sacramento-San Joaquin Valley from the north, where it is perhaps represented today by the redband trout of McCloud River basin, California.
Microsatellite analyses of the trout of northwest Mexico)
Microsatellite analyses show significant allelic frequency differences between Rio Yaqui trout and O. chrysogaster in Sinaloa and Durango Mexico, adding further support for a unique evolutionary status for this group of northwestern Mexican trout.
Impact of Hybridization on a Threatened Trout of the Southwestern United States
This case demonstrates that extreme care must be exercised when considering elimination of any contaminated population lest the unique genetic identity of the native taxon be lost forever.

Comparison of the 1979 and 1989 list of rare North American fishes indicates that recovery efforts have been locally effective for some species, but are cleverer than was earlier believed.
Notes on the Introduction of Salmo Nelsoni Evermann into California from Mexico
A distinct hump on the back, directly above the preopercle at the base of the head, hitherto not described, is suggested as a character by which S. nelsoni may be distinguished from other members of the rainbow series found in the coastal waters of California.

Biochemical Genetic Studies of Native Arizona and New Mexico Trout
Populations of Gila trout, Salmo gilae, and Apache trout, S. apache, as well as a trout from the Rio Mayo, Mexico, were analyzed for protein polymorphisms at 36 presumptive genetic loci using starch gel electrophoresis to evaluate purported hybridization between the native populations and introduced rainbow trout.
