large Colorado squawfish. The Large number of squawfish handled <br />at this time of the year, when little else is going on, makes <br />this effort worth while. Payoffs include basic Life history <br />information not only for Colorado squawfish, but for other species <br />as well and a population census reflecting population status <br />over -time. <br />5. Habitat alteration with discharge (Peaking Power) <br />High water in 1982 and 1983, and the loss of Colorado squawfish <br />recruitment in 1983 has set this program back. Every effort would <br />be made to complete the biological portion of this program in 1984 <br />' or 1985. Two years of biological data is desired, since marking, <br />handling and recapture of YOY Colorado squawfish is difficult work. <br />Sustained low and high flows from Flaming Gorge are also difficult to <br />obtain, depending on discharge priorities. <br />6. Data Analysis <br />Data analysis of 1979-1984 YOY monitoring program would begin in <br />winter 1984-1985. The analyses would be conducted so that easy <br />update is possible as new monitoring data are obtained. Emphasis <br />would be placed on determining sensitive components of the YOY life <br />history stage based on between year fluctuations of abundance as <br />related to the quality of nursery habitat (physical conditions, <br />biological interactions, etc.). An important part of this work <br />includes an evaluation of interactions between Colorado squawfish <br />and other fish species. <br />31 <br />
