<br />. <br /> <br />. <br /> <br />eight radiotelemetered squawfish were equal to or greater than 540 mm <br /> <br /> <br />long and were thought to be mature. <br /> <br />Radio contact with four fish was lost by 6 July. Failure to maintain <br /> <br />contact with these fish was thought to be due to radio transmitter <br /> <br />failure. Fish number 3075 was located the day after radio implantation, <br /> <br />then no further contact was made (Figure 3). Consequently, no movement <br /> <br />data were obtained for this fish. Six observations were recorded for <br /> <br />fish numbers 3024 and 3060 and five for fish number 3026 (Figures 4, 5 <br />and 6). All three fish exhibited downstream movement during this period. <br />Fish number 3036 traveled quickly from its original capture site at <br />RM 50 downstream and into the Green River (Figure 7). Once in the Green <br />River it maintained a relatively stationary position at the confluence of <br />the Green and White rivers through July. No further contact was made <br />with the fish until 28 September when it was located at RM 215.8 of the <br /> <br /> <br />Green River, 30.5 river miles (49.1 km) below the White River con- <br /> <br /> <br />fluence. By 24 November, fish number 3036 had traveled only three <br /> <br /> <br />additional miles (4.8 km) upstream from its 28 September location. <br /> <br /> <br />The most extensive movement data were obtained for the three largest <br /> <br /> <br />squawfish captured. Contact with all three fish was maintained into <br /> <br /> <br />September. Each fish displayed divergent movement. <br /> <br /> <br />Between 17 June and 13 July fish number 3051 moved from RM 64.3 of <br /> <br /> <br />the White River, downstream, out of the White River, to RM 155.8 of the <br /> <br /> <br />Green River (Figure 8). From 13 July through 19 August it remained in <br /> <br /> <br />this general area. Sampling conducted by FWS personnel showed that ripe <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />12 <br /> <br />. <br />
