  <dc:description>&lt;p&gt;&lt;span&gt;The Asiatic clam,&lt;/span&gt;&lt;i class="EmphasisTypeItalic"&gt;Corbicula fluminea&lt;/i&gt;&lt;span&gt;&amp;nbsp;(M&amp;uuml;ller), has extended its range to include the tidal fresh-water portion of the Potomac River, Maryland. Though patchily distributed, the clams have attained densities of 665 m&lt;/span&gt;&lt;span&gt;&amp;minus;2&lt;/span&gt;&lt;span&gt;. Size-class distributions indicate that the clams first appeared in 1975. About 90% of the population belong to year-class I and were less than 12 mm in length. Elsewhere, this species has created severe water quality problems; it should be closely watched in the Potomac.&lt;/span&gt;&lt;/p&gt;</dc:description>
