LIST OF TABLES'

Table

Page

1. Rare fish collections from the San Juan River, Utah during
spring 1988 electrofishing efforts, RMI 135-87. Total
Effort = 30.29 hrs (standardized and target efforts
combined)

13

2. Species list of fishes collected by electrofishing, trammel
netting and yay seining in the San Juan River, San Juan Arm
of lake Powell and adjacent irrigation pond, Utah, 1988 . 14

3. Total number, % species composition and mean CPUE (fish/
mile) of fishes electrofished in the first mile of each
5-mile reach of San Juan River, Utah above RMI 87

17

4. Total number and percent species composition of fishes
collected in the San Juan Arm of lake Powell, Utah. Fish
collected in spring 1987, fall 1987 and spring 1988 by
means of trammel and gill nets

5. Total number, mean CPUE (fish/net-hr) and percent species
composition of fishes collected by trammel nets in the San
Juan River, Utah between river miles 80.3-23.1, 8 July to
20 August 1988. CC = channel catfish, CP = carp, BH =
bluehead sucker and FM = flannelmouth sucker

6. Total number, % species composition and mean catch-per-unit-
effort (CPUE, fish/100m2) for all fishes collected from
backwaters during standardized yay seining in the San Juan
River, Utah, 1988, by general river area. Percent values
were calculated using the total number of fish seined in each
river area. CC = channel catfish, CP = carp, FH = fathead
minnow, FM = flannelmouth sucker, GA = mosquitofish, PK =
plains killifish, RS = red shiner, SO = speckled dace and
= 1.0%. See Appendices E and F for a break down of fish
per 5-mi reach 24

7. Total number, % species composition and mean catch-per-unit-
effort (CPUE, fish/100m2) for all fishes collected during
spring and summer incidental seining in the San Juan River,
Utah, 1988. Areas seined include backwaters, isolated pools,
back eddies and other slow moving riverine habitats. CC =
channel catfish, CP =carp, FH = fathead minnow, FM =
rlannelmouth sucker, GA = mosquitofish, RS = red shiner,
SO = speckled dace and SU = combined suckers 25

8. Mean size and maximum depth of the backwaters sampled
in the San Juan River, Utah, 1988, by general river area.
See Appendix G for the location and habitat measurements
for each backwaters seined . 29
