  <dc:description>&lt;p&gt;&lt;span&gt;Groups of sea lamprey (&lt;/span&gt;&lt;i&gt;Petromyzon marinus&lt;/i&gt;&lt;span&gt;) eggs fertilized by males previously immersed in an aqueous solution of&amp;nbsp;&lt;/span&gt;&lt;i&gt;p&lt;/i&gt;&lt;span&gt;,&lt;/span&gt;&lt;i&gt;p&lt;/i&gt;&lt;span&gt;-bis(1-aziridinyl)-&lt;/span&gt;&lt;i&gt;N&lt;/i&gt;&lt;span&gt;-methylphosphinothioic amide (bisazir) at concentrations of 10&amp;ndash;100&amp;ensp;mg/L produced fewer normal, live prolarvae after 15&amp;ndash;17&amp;ensp;d of incubation than did groups of eggs fertilized by normal males. Mortality of embryos or prolarvae was nearly 100% in groups of eggs fertilized by males that had been immersed in a 50&amp;ensp;mg/L solution of bisazir for 4&amp;ensp;h or in a 100&amp;ensp;mg/L solution for 2&amp;ensp;h. The immersion technique appears to be an efficient method of sterilizing large numbers of male sea lampreys for use in a proposed sterile-male-release program.&lt;/span&gt;&lt;i&gt;Key words&lt;/i&gt;&lt;span&gt;: sea lamprey,&amp;nbsp;&lt;/span&gt;&lt;i&gt;Petromyzon marinus&lt;/i&gt;&lt;span&gt;; pest control, fish control, sterile-male technique, sterilization, chemosterilants, bisazir, Great Lakes&lt;/span&gt;&lt;/p&gt;</dc:description>
