Book excerpt: In the western U.S., the Pacific salmonids (Oncorhynchus spp.) are of significant cultural, socioeconomic and ecological importance. However, despite decades of conservation efforts, their continued decline remains a great concern. Two critical factors impacting the sustainability of salmon and steelhead populations in the Pacific Northwest include genetic introgression of captive-reared hatchery fish and climate warming. Although salmonid hatcheries have been recognized as having a valuable role in restoring wild stocks, gene flow from domesticated hatchery fish into wild populations presents obstacles for conservation. Additionally, climate change is predicted to continue to increase stream temperatures in the Pacific Northwest, which is particularly hazardous for cold-water dependent Oncorhynchus spp., as their physiology, behavior, and distribution are crucially linked to temperature. Here these factors were investigated using clonal lines of rainbow trout (Oncorhynchus mykiss) by evaluating phenotypic responses to these two factors in the context of developing management protocols to facilitate their sustained existence.

This book was released on 2021 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultimate phenotype for a given trait results from the combined influences of underlying genetics and environmental factors; predicting how organisms respond to changing environments thus depends on understanding the relative impacts of genes and environmental variables on phenotypes. Here, I explore how changes in one of the most fundamental environmental variables, temperature, impact phenotypes with strong survival implications for rainbow trout (Oncorhynchus mykiss), and explore the underlying genetic architecture associated with phenotypic change in response to temperature. In this dissertation, I begin by comparing responses of growth, size, body shape, and sprint swimming speed phenotypes to rearing at 10° C and 18° C in two geographically disparate, semi-wild clonal strains of O. mykiss (Whale Rock clonal line, from California, and Swanson clonal line, from Alaska), compared to two clonal strains with hatchery origins (Arlee and Hot Creek clonal lines). I find that Whale Rock and Swanson overall show the greatest between-line differences in these phenotypes, and vary notably in the nature and magnitude of their plastic response to temperature. I then explore the influence of 10° C and 18° C rearing temperature on the location of body fins that potentially influence sprint swimming speeds (dorsal fin, anal fin, and pelvic fins) at 32 and 35 weeks of age in Whale Rock and Swanson clonal lines, with Hot Creek as a hatchery-origin clonal line for comparison. I find complex patterns of variation in fin location at both ages, both within clonal line at different temperatures and between clonal lines within the same temperature. Of the fin locations measured, only one was found to significantly influence sprint swimming speed, which was the distance between the operculum and the most anterior margin of the anal fin. Whale Rock and Swanson showed distinctly disparate differences in fin metrics, again suggesting their suitability for exploring genetic architecture of these phenotypes. Finally, I use a quantitative genetic approach to identify quantitative trait loci (QTL), finding evidence for significant and suggestive QTL influencing the measured phenotypes, as well as evidence for temperature-specific QTL.

Book excerpt: Prediction equations correlating density of fingerling rainbow trout with growth, yield, and food use efficiency indicated that ammonia nitrogen resulting from high fish densities wes responsible for reductions in all three factors. These predictable density-dependent responses present fish-culturists with alternatives of density selection for evaluation and attainment of specific goals. In examples, fish-culturists, by manipulating density, could achieve rapid growth, produce the maximum weight possible, balance yield with cost, optimize fish quality, or combine two or more of these goals.
