Perhaps one of the world\&$\#$39;s most important groups of fish are the species within the Pacific trout complex, due to their harvest in fisheries and use in aquaculture. This dissertation consists of an in-depth evaluation of this group at different scales, from the assessment of biological traits throughout the reconstruction of pedigrees in two populations to a phylogeographic examination of multiple largely undescribed species. Here, a combination of novel molecular techniques allowed me to address critical ecological questions for the management and conservation of this group.In chapter one, I describe the discovery, characterization and development of single nucleotide polymorphisms for O. mykiss for the study of ecological interactions, phylogeography, and conservation status. These tools have great power for population genetic analysis, and for individual identification and pedigree reconstruction. The last allows the tracking of families, and an unprecedented level of evaluation of natural and hatchery populations.Chapter two expands the scope of these molecular tools to provide a powerful means of understanding of biological traits for steelhead hatchery programs in the Russian River, California. Reconstruction of cohort age distributions revealed a strong component of fish that spawn at age two, in contrast to program goals and distinct from naturally spawning steelhead. Correlations between family members in the day of spawning revealed a strongly heritable component to this life history trait and demonstrated the potential for selection to alter life history traits. These results demonstrate the promise of SNP-based pedigree reconstruction for providing biological inference in high-fecundity organisms.Chapter three describes how the molecular tools developed were applied to population genetics of trout inhabiting northwestern Mexico, to elucidate biodiversity, and evolutionary history, and measure introgression from hatchery rainbow trout. Here, I confirmed the vast genetic diversity present in northwestern Mexican trout and provided evidence that trout inhabiting the Sierra Madre Occidental correspond to independent lineages separated from O. mykiss. Introgression from non-native trout was detected, but the genetic integrity of native trout is still maintained. All the information presented in this document will help to guide effective conservation strategies for this globally important group of fishes.

A pesar de que Baja California Sur (BCS) es tipificada como una regi\ón\árida y con pocas corrientes epicontinentales en sus vertientes Pac\ífico y Golfo de California (Tamayo, 1962), existen numerosos cuerpos de agua perennes conocidos como \“oasis\” que representan eocosistemas mes\ófilos relictos de afinidad subtropical (Axelrod, 1948, 1979; Grismer y McGuire, 1993). Estos oasis son habitados por peces con diferentes historias biogeogr\áficas y evolutivas, siendo escenarios de endemismos aut\óctonos (Fundulus lima y Gobiesox juniperoserrai) o de colonizaci\ón v\ía fluvial por especies eurihalinas de estirpe marina (Follett, 1960; Espinosa P\érez y Castro-Aguirre, 1996; Ruiz-Campos et al., 2003). En t\érminos ecogeogr\áficos, no hay peces dulceacu\ícolas de origen primario o secundario en BCS (Follett, 1960) y varios factores causales han sido propuestos para explicar tal situaci\ón: (1) discontinuidad paleohidrol\ógica entre los arroyos del sur de California y de la pen\ínsula de Baja California durante la disminuci\ón del nivel del mar en el Pleistoceno tard\ío; (2) la prolongada aridez prevaleciente desde el inicio del Holoceno ha frenado la dispersi\ón de peces por v\ía estuarina a trav\és de la costa peninsular; (3) lo abrupto de gran parte de la costa oriental ha evitado la formaci\ón de lagunas y complicado la dispersi\ón; y (4) el Golfo de California act\úa como una barrera para la entrada de peces dulceacu\ícolas desde Mesoam\érica. ● Peces dulceacu\ícolas de Baja California Sur Follett (1960) report\ó 21 especies dulceacu\ícolas nativas para BCS, sin ning\ún caso de introducci\ón de especies ex\óticas. Posteriormente, Ruiz-Campos y Contreras-Balderas (1987) incrementaron este n\úmero a 28, aportando primeros registros de tres especies perif\éricas espor\ádicas (Harengula thrissina, Hypsopsetta guttulata y Achirus mazatlanus) y tres ex\óticas (Gambusia affinis, Poecilia reticulata y Xiphophorus maculatus). Muchos de los registros referidos por ambos estudios fueron procedentes de las partes bajas de los r\íos Mueleg\é y San Jos\é del Cabo, pero sin evidencia
