Table 2. Data for 25 adult razorback sucker implanted with radio transmitters
and stocked in the Gunnison River, 7 April 1994 and 13 September
1995. Note: RM=river mile(s); radio frequencies were in the 40 Mhz
band. See Figures 4 and 5 for movements of specific fish and Figure
6 for total maximum upstream and downstream displacement for each
radiotagged fish.

a Total longitudinal movement is defined as the most upstream contact to the
most downstream contact.
b Maximum displacement is defined as the maximum distance moved from release
point following surgery either upstream or downstream during the entire
monitoring period.
Final displacement is defined as the distance from point of release
following surgery to the last contact point: (+) represents upstream
movement, (-) represents downstream movement.
d Stocked 13 September 1995.
