Table 1. Data for 20 adult razorback sucker implanted with radio transmitters
and stocked in the Colorado River, 6 April 1994. Note: RM=river
mile(s); radio frequencies were in the 40 Mhz band. See Figure 2
for movements of specific fish and Figure 3 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 Tag eventually recovered. Dates tags were recovered:
.110--08/25/94; .300--08/09/94; .320--05/12/94; .360--07/26/94
