<p><span>We examined the role that predation of infected conspecific fish and postcyclic transmission might play in the life cycle of the Asian fish tapeworm, </span><i>Bothriocephalus acheilognathi</i><span><span> </span>(Cestoda: Pseudophyllidea) Yamaguti, 1934. Young-of-the-year (YOY) bonytail chub (</span><i>Gila elegans</i><span>) were exposed to copepods infected with<span> </span></span><i>B. acheilognathi</i><span><span> </span>and subsequently fed to subadult bonytail chub. Within 1 wk after consumption of the YOY chub, subadults were necropsied and found infected with gravid and nongravid tapeworms. This study provides evidence that postcyclic transfer of<span> </span></span><i>B. acheilognathi</i><span><span> </span>can occur. Postcyclic transmission may be an important life history trait of<span> </span></span><i>B. acheilognathi</i><span><span> </span>that merits consideration when studying the impact and distribution of this invasive and potentially pathogenic tapeworm.</span></p>
