<br />59 <br /> <br />within the CRE, it is important not only to monitor the future incidence of parasitism and <br /> <br />disease, but to document a baseline condition before initiation ofTCD. <br /> <br />. <br /> <br />Summary Project Description: A survey of the parasites of fish of the Colorado River and <br />selected tributaries will be conducted over an 18-20 day period in June-July 2006. Fish will be <br />collected by AZGD fish biologists using a combination of electroshocking (boat and backpack), <br />seining, minnow trapping, trarnnlel netting and hoop netting. Fish will be collected by AZGD <br />fish biologists and nccropsied by parasitologists from the National Wildlife Health Center <br />(NWHC), Madison WI on site. Approximately 10-15 fish of each species will be necropsied at <br />each collection point. Parasite samples collected will be preserved and transported back to the <br />NWHC for identification and enumeration. Aquatic invertebrate samples at each sample site will <br />be collected to assess the ability of intermediate hosts to spread into the mainstem as water <br />temperature increases. We will especially monitor the presence/absence of the New Zealand <br />mudsnail Potamopyrgus antipodarum (Gray). After the initial survey, the investigators will <br />design a program to monitor changes in the parasite community over time. It is estimated that a <br />field survey trip of smaller magnitude would be encouraged every 5-7 years. <br /> <br />Ie <br /> <br />MO's and RlN's ADDRESSED: Goal 2: M.O. 2.5 <br /> <br />Status/Schedule: This project will begins in late FY05 and ends in FY07. <br /> <br />Implications of Experimental vs. Non-Experimental Budget: Outside Science/labor: Project <br /> <br />was funded in FY05.
