Data from: Increased natural reproduction and genetic diversity one generation after cessation of a steelhead trout (Oncorhynchus mykiss) conservation hatchery program

Barry A. Berejikian & Donald M. Van Doornik
Spatial and temporal fluctuations in productivity and abundance confound assessments of captive propagation programs aimed at recovery of Threatened and Endangered populations. We conducted a 17 year before-after-control-impact experiment to determine the effects of a conservation hatchery program for anadromous steelhead trout (Oncorhynchus mykiss) on a key indicator of natural reproduction (naturally produced nests or 'redds'). The supplemented population exhibited a significant (2.6-fold) increase in redd abundance in the generation following supplementation. Four non-supplemented (control)...

Data from: Water, water everywhere: environmental DNA can unlock population structure in elusive marine species

Kim M. Parsons, Meredith Everett, Marilyn Dahlheim & Linda Park
Determining management units for natural populations is critical for effective conservation and management. However, collecting the requisite tissue samples for population genetic analyses remains the primary limiting factor for a number of marine species. The harbor porpoise (Phocoena phocoena), one of the smallest cetaceans in the Northern Hemisphere, is a primary example. These elusive, highly mobile small animals confound traditional approaches of collecting tissue samples for genetic analyses, yet their nearshore habitat makes them highly...

Data from: Genomewide association analyses of fitness traits in captive-reared Chinook salmon: applications in evaluating conservation strategies

Charles D. Waters, Jeffrey J. Hard, Marine S.O. Brieuc, David E. Fast, Kenneth I. Warheit, Curtis M. Knudsen, William J. Bosch, Kerry A. Naish & Marine S. O. Brieuc
A novel application of genome-wide association analyses is to use trait-associated loci to monitor the effects of conservation strategies on potentially adaptive genetic variation. Comparisons of fitness between captive- and wild-origin individuals, for example, do not reveal how captive rearing affects genetic variation underlying fitness traits or which traits are most susceptible to domestication selection. Here, we used data collected across four generations to identify loci associated with six traits in adult Chinook salmon (Oncorhynchus...
