One bony tail chub adult and one juvenile were tagged but not

i

recaptured during the study. Fourteen adult and 9 juvenile chubs
from Desolation and Gray canyons were also tagged but none were
recaptured.

Fishes Associated with the Rare Species
Table 3 summarizes the fishes, by size class, found in seine
samples containing rare species. These data give a preliminary
view of potential competition between species. Young introduced
species were found more often than native fishes in samples con-
taining rare "species. Red shiners, more than any other species,
were found in the same samples as rare fishes.

The data in Table 3 indicate that young-of-the-year Colorado

squawfish were found most commonly with red shiners, fathead min-
nows, juvenile carp, and young-of-the-year channel catfish. Juve-
nile squawfish were found most often with red shiners, juvenile
roundtail chub, and young-of-the-year flannelmouth and bluehead

suckers.

Young-of-the-year and juvenile humpback chubs were found most
commonly with red shiners, fathead minnows, and young-of-the-year
channel catfish. Adult humpback chubs were found most commonly
with red shiners and juvenile humpback chubs.
