. . I. Characterize present fish community, including endangered fish in in the Gunnison River, confluence with the North Fork of the Gunnison to confluence of the Colorado River with methodologies that will allow comparison to past survey data (USFWS, 1979-81, CDOW 1977-82). 2. Evaluate potential spawning of Colorado squawfish in the Gunnison River above Redlands Diversion Dam utilizing radiotelemetry studies. IV. Study Area (river miles and sampling dates, if appropriate) Gunnison River from confluence with the Colorado River to the confluence with the North Fork of the Gunnison (river mile 0-75). V. Study Methods/Approach Conduct extensive sampling using electrofishing, entanglement netting, trap netting, and seining, etc. to collect fish. This effort will be combined with the USFWS effort to locate and evaluate previously stocked fish in the Gunnison River. This will not only reduce costs but also minimize sampling effort to accomplish both objectives. Compare numbers, length-frequency distribution and location to survey data collected in the Gunnison River 10 years ago. PIT ta9 and collect tissue samples for genetic analysis from all juvenile and adult endangered fish collected. In addition adult Colorado squawfish will be radio-tagged to monitor movement and evaluate potential spawning activity. VI. Task Description (FY-1994) Task I. Monitor radio-tagged adult Colorado squawfish throughout the winter or until radio transmitter signals expire. Task 2. Input field data into d-BASE; analyze summarize findings; compare present study findings with past fishery survey and inventory data; prepare draft and final report. VII. Study Schedule (start/end by Task) Task I. 4/92~10/92; 4/93~10/93 Task 2. 4/92~10/92; 4/93~10/93 Task 3. 4/92~7/94 Task 4. 10/93~7/94 2
