<br />reach). In 1996, all available information on the Price River will be <br />located (Objective 4) and the first summer of biological data will be <br />summarized in a report." We will tie this report into the Flaming Gorge <br />synthesis. After the three year study, a completion report will be <br />finished that will include a synthesis of the 3 years of biological data <br />collected in Objectives 1-) and a synthesis of all available historical <br />information (Objective 4). <br /> <br />Objective 1. <br /> <br />Year 1 <br /> <br />The Price River will be sampled from runoff through the estimated <br />spawning season. This will constitute three sampling trips (pre-runoff, <br />runoff, and post-runoff). Each trip will require about 5-7 sampling <br />days. All s~pling trips will begin near Grassy trail Creek and sampling <br />will proceed downstream to the confluence with the Green River <br />(approximately 40-50 miles). Depending on sampling conditions for each <br />trip, a combination of the following sampling gear types will be <br />utilized to catch adult/juvenile fish: boat electrofishing, backpack <br />electrofishing, seining, and trammel nets. During higher flows, boat <br />electrofishing will be utilized for ru~s and riffles (proceeding in a <br />downstream direction), and where possible in backwaters and eddies. <br />When flaws do not permit boat electrofishing, a backpack electrofishing <br />unit will be used to sample the main channel, runs, and riffles <br />(sampling will proceed in an upstream direction), and where possible in <br />backwaters and eddies4 If nece9sary, two backpack electrofishing units <br />will be used in the ~ain channel (side by side with two netters) and in <br />larger backwaters to increase capture efficiency. Seining and tr~nel <br />nets will be conducted in low-velocity habitats (e.g. backwaters, side <br />channels, etc.), eddies, ar.d riffles not conducive to electrofishing or <br />where capture efficien~y (as compared to electrofishing) will not be <br />jeopardized~ At least one sampling method will be used during every <br />sampling trip to allow direct comparisons between trips (e.g. 50-100 m <br />of shcreline could be s~pled eve~y S km of river). All native fishes <br />\vill be measured (TL in rom), weighed (nearest g), PIT-cagged (if large <br />enoughj, and released; a subs~ple of nonnative fishes will be measured <br />and weighed and the remaining fish will only be counted. Nonnative <br />fishes need to be adequately monitored duri.ng this survey in the Price <br />River in order to determine if the Price River is a potential source <br />population for nonnative fishes in the Green River. <br /> <br />During the April sampling trip, stations will be established based on <br />geomorphology (e.g. an abundance of low-velocity areas for Objective 2), <br />fish distribution, accessibility, and logistics. We will chose the <br />stations to provide a representative overview of the river. Two or <br />three stations will be established between Gras9ytrail Creek and <br />Woodside, UT and 2 stations will be established between Woodside, UT and <br />the confluence with the Green River (one directly below Woodside and one <br />directly upstream from and including the confluence). After flows have <br />receded and the river is unnavigatable, only the established stations <br />will be monitored each month until September. <br />
