Pace
1. Correction factor used to adjust total number of Colorado squawfish in samples
that were not preserved and percent increase in total fish collected used in
CPE calculations.. 6
2. Dates when YOY Colorado squawfish monitoring occurred and average of mean-
daily river flow (cfs) during the sampling period at USGS gaging stations nearest
to the four ISMP sampling reaches. 8
3. Correlation (Pearson Correlation Coefficient), by sampling reach, of geometric-
mean CPE for YOY Colorado squawfish during fall ISMP sampling with seasonal
flow events at the nearest USGS gaging station, 1986-1992. 12
4. Correlation (Pearson Correlation Coefficient) of mean total length of YOY
Colorado squawfish collected during fall monitoring with accumulated temperature
units (sum of the difference [positive values only] between average main channel
temperature and 12, 16, and 20 °C) for the four reaches sampled during ISMP. 13
5. Correlation (Pearson Correlation Coefficient), by sampling reach, of mean total
length of YOY Colorado squawfish during fall ISMP sampling with seasonal flow
events at the nearest USGS gaging station, 1986-1992. 14
6. Number of backwaters sampled and percent of backwaters containing at least one
Colorado squawfish, Interagency Standardized Monitoring Program, 1986-1992. 15
7. Dates when subadult-adult Colorado squawfish monitoring occurred and average of
mean-daily river flow (cfs) during the sampling period at USGS gaging stations
nearest to the ISMP sampling reaches. 32
Comparison of capture efficiency of the subadult-adult Colorado squawfish
monitoring program with sampling programs using 'block and shock' or 'scare and
snare' . 46
9. Average river flow (cfs) of the Colorado River during Humpback Chub
Monitoring, 1986, 1988, and 1991. Average of mean-daily flows measured at the
USGS gaging station located near the Colorado-Utah Stateline. . , 59
10. Total number of Gila spp. caught during ISMP sampling, and mean and total catch
per effort (CPE, fish per hour of trammel netting) in Westwater Canyon and Black
Rocks-1986, 1988, and 1991. 60
11. Total number of fish other than Gila spp. collected during ISMP sampling in Black
Rocks and Westwater Canyon-1986, 1988, and 1991. 62
