- Abstract
The native trout of New Mexico and Arizona have been managed for conservation for almost 80 years and are currently listed under the US Endangered Species Act. Management of these populations has improved the outlook for these species. However, because of a history of non-native salmonids being stocked in the region, genetic analysis of the remaining populations is necessary to ensure that each population is as representative as possible of ancestral populations of Gila (Oncorhynchus gilae) and Apache (Oncorhynchus gilae apache) trout. Here we provide a multi locus genotypic assessment of 19 populations of native southwestern trout that strongly indicates that management has maintained the genetic integrity of these species, while restoring each species to a number of historically occupied streams.
