  <dc:description>&lt;h3 id="tafs10462-sec-1000-title" class="article-section__sub-title section1"&gt;Objective&lt;/h3&gt;&lt;p&gt;Dams and reservoirs can alter juvenile growth and survival of migratory salmonids through several physical and biological mechanisms. Juvenile Chinook Salmon&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Oncorhynchus tshawytscha&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;that are produced upstream of large hydropower dams may have associated passage mortality, but the reservoirs created by these dams can support rapid growth. Characterizing the biotic drivers of growth and mortality in reservoirs may aid in understanding the cumulative effects of river impoundments on migratory salmonid populations. The purpose of this study was to understand how reservoirs facilitate rapid growth in juvenile Chinook Salmon.&lt;/p&gt;&lt;h3 id="tafs10462-sec-2000-title" class="article-section__sub-title section1"&gt;Methods&lt;/h3&gt;&lt;p&gt;We analyzed stomach contents to determine diet composition throughout the summer and fall. We also recorded prevalence of the parasitic nematode&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Philonema&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;sp. in the coeloms of fish.&lt;/p&gt;&lt;h3 id="tafs10462-sec-3000-title" class="article-section__sub-title section1"&gt;Result&lt;/h3&gt;&lt;p&gt;We found that juvenile Chinook Salmon frequently consumed young-of-year centrarchids, which likely contributed to rapid growth. Piscivory was highest from July through October and decreased with surface temperature from November through December. Correspondingly, zooplankton and arthropod consumption increased in November and December. Prevalence of visible&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Philonema&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;sp. infections in the coelom was high (34.6%), negatively associated with time, and nonlinearly associated with fork length.&lt;/p&gt;&lt;h3 id="tafs10462-sec-4000-title" class="article-section__sub-title section1"&gt;Conclusion&lt;/h3&gt;&lt;p&gt;These findings reveal unique diet patterns and suggest potential parasite-associated mortality in reservoir-rearing Chinook Salmon, but more detailed studies across a longer time scale are needed to robustly assess the population-level effects of this parasite.&lt;/p&gt;</dc:description>
