maximum displacement is defined as the maximum distance moved from release point following release either
upstrea m or downstream dur ing the entire moni toring period.
d final displacement is defined as the distance from the captu re point follow ing implantation of the radiotag
to the last contact point: (+) represents upstream movement, (-) represents down stream movement.
