. . Local Movement. Local movement describes activity of the fish within a localized area, with no significant change in position, up or downriver. This pattern often involved movement between two to four 'preferred sites' (where the fish spent most of its time) within a localized area or habitat such as an eddy or backwater. ~cal movement was mo~y ggnfined to an area of 9-400 s,gyare meters, and was observed during either 2-hour or 24-hour mpnitoring. Local movement patterns were most ~n w~th Colorado squawfish, and may be associated with feeding behavior. All movements were estimated in linear distance (meters) either up or downstream and in or out from shore, relative to the point of first contact during that monitoring period. The fish that were observed in this local movement pattern during moni to ring were located by triangulation as often as possible. It was noted that generally the fish spent most of their time in specific sites to which they often returned during the local movement. As described earlier, habitat measurements were recorded only if the fish was observed stationary for at least 15 minutes. . . . Long-Range Movement. Long-range movement was associated with a fish that changed position in the river significantly. This movement was considered transitory, between habitats located some distance apart. Although long-range movement was generally documented as occurring between radiotracking trips, this movement pattern was also observed during the 2-hour and 24-hour monitoring. On two occasions, once while monitoring a razorback and once while monitoring a squawfish, the fish were contacted during relatively long-range or transi tory movements. In both cases, the fish were located later in the day 0.1 to 0.2 miles downstream. When relocated, the razorback sucker had assumed a no-movement pattern in a slow run and the squawfish a localized movement pattern in a small backwater. During 24-hour monitoring, either species would often exhibit all three types of movement patterns. Movement by razorback suckers during the 24-hour period ranged from absolutely no movement to movements of up to 125 meters from the point where initially contacted. Movements made by Colorado squawfish ranged from short local movements within a discrete area to long range transitory movement of up to 0.5 miles. . . . The long range movement exhibi ted by adult Colorado squawfish and razorback suckers during this winter investigation were examined. The site of capture, release and relocation of each radiotagged fish are presented in Table 4. Net and total movement figures do not include the distance from the release site to the location of first radio contact. It appears that ~of the ~sh ~ substantial movemen~s ~ the ~oint of release beforE settling down into a localized area. For example, one razorback sucker (Carlin tag #3266) moved 31.6 miles downstream from the release site and remained in the same location for the remainder of the study. The mean distance moved by Colorado squawfish between the release site and the location of first radio contact was 6.2 miles with a range of 0.1 to 16.6 miles; for razorback suckers, 7.2 miles with a range of 0.1 to 31.6 miles. . . 17 .
