  <dc:description>&lt;div class="hlFld-Abstract"&gt;&lt;p class="last"&gt;We conducted a relocation study of unionid mussels in Navigation Pool 7 of the upper Mississippi River (river mile 713.2) to evaluate survival after handling and aerial exposure. Two separate studies were conducted to compare seasonal differences in mussel survival; the first was initiated in June and the second in October.&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;u class="uu"&gt;Amblema plicata plicata&lt;/u&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;(subfamily Ambleminae) and&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;u class="uu"&gt;Obliquaria reflexa&lt;/u&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;(subfamily Lampsilinae) were studied. Mussels were marked, held out of water for either 0, 1, 4, or 8 h, and then placed into a 3 × 3 m grid (divided into nine 1-m&lt;sup&gt;2&lt;/sup&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;units). The mussels were re-examined after four-five months to measure mortality in the control and treatment groups. Mussels of both species had &amp;gt;90% survival after aerial exposure up to 4 h in both studies. However, survival (number recaptured live/number recaptured live and dead) of mussels showed a decreasing trend with duration of exposure in the first study, but not in the second study. The overall recovery of marked mussels (number recaptured/number marked) was 91% in the first study and 87% in the second study. However, only 37% of&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;u class="uu"&gt;O. reflexa&lt;/u&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;mussels in the 8-h treatment were recovered in the first study; the adjusted survival (number live recaptured/number marked) of this treatment group was significantly (p &amp;lt; 0.05) lower (35%) than all other treatments.&lt;/p&gt;&lt;/div&gt;</dc:description>
