III. Project Summary:

This project monitors populations of endangered fishes in Utah. The following objectives
have been outlined for young-of-the-year (YOY) Colorado pikeminnow:

I. Develop annual indices of relative abundance ofYOY Colorado pikeminnow.

2. Determine trend(s) in these indices.

3. Determine relationships between these indices and stream flow, water temperature,
abundance of sympatric fishes, and physical characteristics of backwaters.

The annual Interagency Standardized Monitoring Program (lSMP) activities for the 2002
field season included fall seining for young-of-the-year Colorado pikeminnow. The late-
juvenile/adult Colorado pikeminnow monitoring portion ofISMP ended with sampling in
2000. Efforts are now being directed toward developing abundance estimates as a means of
monitoring populations and tracking progress toward recovery.

Middle Green River

Fall seining for young-of-year failed to produce any Colorado pikerninnow in 2002. This is
the first year that no YOY Colorado pikeminnow were collected in the middle Green River
since ISMP monitoring began in 1986. The previous year (2001) was also a poor year for
