Service, Ft. Collins, Colorado). The preferred habitat information, in
conjunction with river cross-section measurements, give an indication
of the amount of preferred habitat available in a given river reach. Cross-
sectional measurements were not included within the scope of the present
study, except for one set of measurements taken near a concentration of
young-of-the-year Colorado squawfish. It was anticipated that future
studies would involve the complete instream methodology, so data during
this study were taken to be of maximum use in those future efforts.
Rare fishes of sufficient size, usually over 100 rom TL, were tagged
with green plastic, numbered fingerling tags (3/8" x 1/8") that were sewn
to the fish just below the dorsal fin with two-pound test monofilament
line. Juvenile squawfish less than 100 mm were marked by clipping the
end of the anal fin. Postlarval squawfish were planned to be marked with
a 50,000-75,000:1 solution of Bismark brown Y stain.
