  <dc:description>&lt;p&gt;&lt;span&gt;A series of species introductions, overexploitation, and habitat modification preceded the extirpation of Lahontan cutthroat trout (&lt;/span&gt;&lt;i&gt;Oncorhynchus clarkii&lt;/i&gt;&lt;span&gt;&amp;nbsp;henshawi; LCT), historically the apex predator, from Lake Tahoe, California-Nevada, USA. Studies evaluating limiting factors for LCT emphasise the need to elucidate food web interactions, yet important knowledge gaps regarding trophic interactions among nonnative pelagic fishes and invertebrates remain. We quantified the abundance and consumption demand of planktivores with an emphasis on kokanee (&lt;/span&gt;&lt;i&gt;Oncorhynchus nerka&lt;/i&gt;&lt;span&gt;) and&amp;nbsp;&lt;/span&gt;&lt;i&gt;Mysis diluviana&lt;/i&gt;&lt;span&gt;. We synthesised this new information with existing information for lake trout (&lt;/span&gt;&lt;i&gt;Salvelinus namaycush&lt;/i&gt;&lt;span&gt;). The seasonal supply of copepods satisfied the consumption demand of kokanee, but only supported low feeding and growth rates. Kokanee relied heavily on&amp;nbsp;&lt;/span&gt;&lt;i&gt;Mysis&lt;/i&gt;&lt;span&gt;&amp;nbsp;as prey, an unusual result.&amp;nbsp;&lt;/span&gt;&lt;i&gt;Mysis&lt;/i&gt;&lt;span&gt;&amp;nbsp;exhibited a high degree of herbivory initially followed by heavier consumption on copepods by larger individuals. Consumption demand for&amp;nbsp;&lt;/span&gt;&lt;i&gt;Mysis&lt;/i&gt;&lt;span&gt;&amp;nbsp;on copepods exceeded that of kokanee during all seasons.&amp;nbsp;&lt;/span&gt;&lt;i&gt;Mysis&lt;/i&gt;&lt;span&gt;&amp;nbsp;contributed to over 50% of the annual energy budget for lake trout up to 625 mm. Consumption of&amp;nbsp;&lt;/span&gt;&lt;i&gt;Mysis&lt;/i&gt;&lt;span&gt;&amp;nbsp;by lake trout and kokanee represented a significant source of mortality when compared to the production of&amp;nbsp;&lt;/span&gt;&lt;i&gt;Mysis&lt;/i&gt;&lt;span&gt;. Predation on kokanee was sustainable, only involved lake trout &amp;gt;625 mm, and was focused on prespawning aggregations. Despite the presence of&amp;nbsp;&lt;/span&gt;&lt;i&gt;Mysis&lt;/i&gt;&lt;span&gt;-fueled lake trout, kokanee have persisted; a noteworthy pattern when considering the negative responses of kokanee to nonnative lake trout and&amp;nbsp;&lt;/span&gt;&lt;i&gt;Mysis&lt;/i&gt;&lt;span&gt;&amp;nbsp;observed elsewhere. This pattern suggests that there may still be an effective niche for LCT in the invaded Lake Tahoe ecosystem.&lt;/span&gt;&lt;/p&gt;</dc:description>
