Diadromy is an unusual but widely distributed form of migration in fishes, and thus understanding these fishes requires a full knowledge of their behavior in both marine and freshwater environments. Freshwater ecology is easier to study and so our understanding is more advanced compared to our understanding of their marine ecology. This dissertation was focused on anadromous salmonids that were hypothesized to express a range of marine migration patterns from estuarine resident to ocean-bound migrants, in a suite of species native to Puget Sound: steelhead trout (Oncorhynchus mykiss), coastal cutthroat trout (O. clarkii clarkii), bull trout ( Salvelinus confluentus), and Chinook salmon (O. tshawytscha ). The study results will help inform a general model of the marine migrations of these salmonids within the Puget Sound. The study is organized into chapters by species. Abstracts for each chapter are described below.

520 $a Diadromy is an unusual but widely distributed form of migration in fishes, and thus understanding these fishes requires a full knowledge of their behavior in both marine and freshwater environments. Freshwater ecology is easier to study and so our understanding is more advanced compared to our understanding of their marine ecology. This dissertation was focused on anadromous salmonids that were hypothesized to express a range of marine migration patterns from estuarine resident to ocean-bound migrants, in a suite of species native to Puget Sound: steelhead trout (Oncorhynchus mykiss), coastal cutthroat trout (O. clarkii clarkii), bull trout ( Salvelinus confluentus), and Chinook salmon (O. tshawytscha ). The study results will help inform a general model of the marine migrations of these salmonids within the Puget Sound. The study is organized into chapters by species. Abstracts for each chapter are described below.
520 $a This dissertation describes the movements of individual anadromous salmonids of four species to determine the extent to which migration patterns vary among the species, populations and marine sub-basins within Puget Sound. The study took a comparative approach between species and was part of a larger suite of studies that investigated 1) marine migrations of ocean-bound stream-type fish (steelhead); 2) marine distribution, residency, and movement of resident and semi-resident pelagic species (Chinook and coho salmon, conducted by other researchers and reported in other publications); 3) movement and habitat use of two different estuarine and nearshore resident species (cutthroat and bull trout); and 4) movement and habitat use in estuarine and freshwater areas by maturing pelagic species (Chinook and sockeye salmon).
520 $a Enhanced understanding of marine migrations and habitat use by anadromous salmonids is necessary for their conservation. The Puget Sound's estuaries and shorelines have been affected in many ways by human actions including industrial and agricultural development of estuaries, construction of docks and marinas, and armoring of beaches. The tendency for salmonids to use these estuarine and marine habitats may cause their populations to decline if preferred habitats are degraded or lost. Information on movements and habitat use patterns is an essential component of conservation plans for these species and provides important links to species that prey on salmon, notably killer whales and other marine mammals.
520 $a Three species considered in this study are listed as threatened under the Endangered Species Act; information on their life history and habitat use will provide essential information to sustain and recover Puget Sound populations. The study resulted in collaborative relationships between tribes, agencies and sporting groups acting as a nexus for organizations interested in research needed to manage Puget Sound salmonids. The results fostered research in other areas that will be useful for generating an understanding of marine life histories elsewhere. (Abstract shortened by ProQuest.).
