  <dc:description>&lt;div id="Abs1-section" class="c-article-section"&gt;&lt;div id="Abs1-content" class="c-article-section__content"&gt;&lt;p&gt;Research on Lake Pend Oreille, Idaho, has focused on the influence of two potential limiting factors for kokanee&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Oncorhynchus nerka&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;(Walbaum, 1792): competition for food with&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Mysis diluviana&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;(Loven, 1862, hereafter&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Mysis&lt;/i&gt;) and predation by lake trout&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Salvelinus namaycush&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;(Walbaum, 1792). Population fluctuations of&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Mysis&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;and lake trout have resulted in substantial heterogeneity in food web conditions, apparently altering both bottom-up and top-down dynamics. Therefore, relative importance of predation and competition were evaluated as drivers of kokanee abundance, biomass, and production. A series of general linear models was used to evaluate relative influences of&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Mysis&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;and lake trout on kokanee. Kokanee production was a density-dependent process and the collapse of&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Mysis&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;corresponded to an increase in the modeled maximum annual production of kokanee from 224 tonnes to 408 tonnes. Lake trout also negatively influenced kokanee biomass. A&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Mysis&lt;/i&gt;-mediated, predator-induced kokanee biomass collapse occurred when lake trout and&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Mysis&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;abundances were both high. Sustainable management of this fishery requires recognition that competition with&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Mysis&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;will define the scope of kokanee production and therefore the scope of sustainable predation.&lt;/p&gt;&lt;/div&gt;&lt;/div&gt;&lt;div id="cobranding-and-download-availability-text" class="note test-pdf-link"&gt;&lt;br&gt;&lt;/div&gt;</dc:description>
