<br />during connection or died later in the summer. <br />~ Razorback suckers from the cohort stocked into Above Brennan in the spring of <br />2000 were never captured. The exact cause of their disappearance is unknown. <br /> <br />However, dead razorback sucker from this age class were observed floating against the <br />leads of breach traps during connection. This suggests some if not all may have died <br />shortly after stocking. Although there is no evidence supporting it, another possibility is <br />~ they left the site during connection. <br />Larval razorback sucker were stocked into The Stirrup site in 1999 and into <br />Baeser Bend in 2001 (Table 1). Survival of larval razorback sucker was never detected <br />~ during the study. <br />Growth <br /> <br />Growth rates of age-1 razorback sucker stocked in 1999 were identical in The <br />Stirrup and Above Brennan sites for the first growing season. Growth rates of <br />razorback sucker averaged 1.3 mm/day and 2.1 to 2.2 grams/day, respectively (Figures <br />~ 9 and 10). In The Stirrup, razorback sucker grew from an average length of 110 mm at <br />stocking to 317 mm in September (Figure 11). Weight gains averaged 336 grams (12.8 <br />g at stocking to 348 g). Razorback sucker in Above Brennan grew from an average <br />~ length of 96 mm at stocking to 310 mm in October (Figure 12). Weight gains averaged <br />347 grams (12.8 g at stocking to 360 g). <br />Length frequencies and average fish size in The Stirrup and Above Brennan <br />sites for April 2000 sampling were similar to fall 1999 sampling (Figures 11 and 12). <br />Spring 2000 was last time razorback sucker were caught in The Stirrup site during the <br />~ study. In Above Brennan growth monitoring of razorback sucker from the age class <br />14 <br /> <br />
