Length of prey was positively correlated with length of slimy sculpin. At a given depth, mean length of slimy sculpins was greater at Rochester than at Nine Mile Point, and mean length increased with depth at both locations. Frequency of occurrence of&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Mysis&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;in the stomachs of slimy sculpins increased with depth, whereas frequency of&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Diporeia&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;generally decreased with depth.&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Diporeia&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;dominated the slimy sculpin diet at 55 m, whereas&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Mysis&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;dominated the diet at 95 m. Slimy sculpins, some as small as 30 mm long, fed successfully on&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Mysis&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;in Lake Ontario. We suggest that extirpation of the deepwater sculpin (&lt;i&gt;Myoxocephalus thompsoni&lt;/i&gt;) and perhaps the coregonines (&lt;i&gt;Coregonus&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;spp.) in Lake Ontario allowed slimy sculpins to expand into deeper areas where they could exploit&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Mysis&lt;/i&gt;. We also suggest that at depths ≥75 m in Lake Ontario, the current&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Mysis&lt;/i&gt;-benthivore link with slimy sculpins may be similar to the past when deepwater sculpins were present.&lt;/p&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div id="preview-section-introduction"&gt;&lt;br&gt;&lt;/div&gt;</dc:description>
