  <dc:description>&lt;p&gt;&lt;span&gt;Examination of the branchial cavities of 8347 adult bloaters (&lt;/span&gt;&lt;i&gt;Coregonus hoyi&lt;/i&gt;&lt;span&gt;) collected from seven locations in Lake Huron for parasitic copepods yielded only the lernaeopodid&amp;nbsp;&lt;/span&gt;&lt;i&gt;Salmincola corpulentus&lt;/i&gt;&lt;span&gt;; its distribution was limited to bloaters collected in the southern two-thirds of the lake. The infections were highest off Au Sable Point and on Six Fathom Bank, where 12 and 22%, of the bloaters examined were infected, respectively. All copepods seen were sexually mature females. The dorsal anterior portion of the branchial rim was the preferred site of attachment. The prevalence of&amp;nbsp;&lt;/span&gt;&lt;i&gt;S&lt;/i&gt;&lt;span&gt;.&amp;nbsp;&lt;/span&gt;&lt;i&gt;corpulentus&lt;/i&gt;&lt;span&gt;&amp;nbsp;increased with length of the bloaters, reaching a maximum of 40% in fish longer than 330&amp;ensp;mm; none were seen in bloaters shorter than 182&amp;ensp;mm. The mean intensity of&amp;nbsp;&lt;/span&gt;&lt;i&gt;S&lt;/i&gt;&lt;span&gt;.&amp;nbsp;&lt;/span&gt;&lt;i&gt;corpulentus&lt;/i&gt;&lt;span&gt;&amp;nbsp;was unusually low (1.0&amp;ndash;1.9) for a lernaeopodid copepod and the maximum number of copepods found on a single bloater was five. Prevalences of copepods differed significantly (&lt;/span&gt;&lt;i&gt;P&lt;/i&gt;&lt;span&gt;&amp;ensp;&amp;lt;&amp;ensp;0.05) between bloaters collected at different geographic locations, suggesting that&amp;nbsp;&lt;/span&gt;&lt;i&gt;S&lt;/i&gt;&lt;span&gt;.&amp;nbsp;&lt;/span&gt;&lt;i&gt;corpulentus&lt;/i&gt;&lt;span&gt;&amp;nbsp;may be of value in bloater stock determination.&lt;/span&gt;&lt;/p&gt;</dc:description>
