<br />Principal Investigators: Coggins, and technician, U.S. Geological Survey, (GCMRC), U.S. <br />Fish and Wildlife Service, Arizona Game and fish Department, and SWCA, Inc. <br /> <br />Statement of Problem: The downstream fish community is an assemblage of native and non- <br />native fish that occur in the Colorado River ecosystem. This assemblage is exclusive of the trout <br />fishery that is managed in Glen Canyon by the Arizona Game and fish Department. The <br />constituents include four native fish and introduced competitors/predators like rainbow trout, <br />brown trout, channel catfish, carp, and other non-native forms. The status and trends of the <br />fishery are regulated by biotic and abiotic mechanisms that may in tum be affected by the <br />operations of Glen Canyon Dam. Monitoring basic population statistics including recruitment, <br />abundance, and distribution of native and non-native fishes provide the fundamental information <br />necessary to assess the status of these resources and the attainment of program goals and <br />objectives. <br /> <br />Summary Project Description: Since 2000, GCMRC and cooperators have been developing a <br />long-term monitoring program for fishes in the CRE. To date, significant progress has been <br />made toward this end such that it is now appropriate for GCMRC to formalize a long-term <br />monitoring program for key non-native fishes (i.e. rainbow trout, brown trout, and common <br />carp). The FY 06 funding recommendation is sufficient to maintain downstream monitoring in <br />the Little Colorado River and in the mainstem for salmonids. Remaining funds will be used to <br />continue development and implementation of the long-term monitoring program. <br /> <br />MO's and CMIN's ADDRESSED: Goal 2 and 4, MO's 2.1,2.2,2.3,2.4, and 4.2; CMIN's <br />1.1.1,2.1.1,2.4.1,2.6.1, EIN 2.1.1,2.1.2,2.1.3. <br /> <br />Status/Schedule: This is on-going work associated with monitoring development and <br /> <br />evaluation. The LCR component will undergo review in FY06. <br /> <br />Implications of Experimental vs. Non-Experimental Budget: Outside Science/labor: <br /> <br />Allocation is unchanged, but still remains below FY04 funding levels. Logistics: logistics is <br /> <br />reduced by $5,000. In the non-experimental budget scenario, logistics is restored to 130,000 <br /> <br />levels. Training/travel related costs: not changed. Operations/supplies: remains unchanged for <br /> <br />GCMRC FY2006 Annual Work Plan (Draft, June to, 2005) <br /> <br />47 <br /> <br />. <br /> <br />- <br /> <br />. <br />
