<br />stocked in 1999 continued through the spring of 2001. Their average size following the <br />~ second growing season (fall 2000) was 410 mm and 863 grams (Figure 13). Average <br />growth rates for the second growing season were 0.5 mm/day and 2.6 grams/day <br /> <br />(Figure 14). In spring 2001, average fish size was similar to fall 2000 average size at <br />412 mm and 932 grams (Figure 13). <br />At Baeser Bend it is important to distinguish between both groups of age-1 <br />razorback sucker that were stocked in 1999 (Table 1). The first group was stocked in <br />April and numbered 1,985 fish. A second group of 204 fish were stocked in July (Table <br />1). These were the fish returned and raised at the hatchery to monitor mortality from <br />~ stocking stress. Fish stocked in July had their right pelvic fin clipped to distinguish them <br />from fish stocked in April. Growth monitoring for both groups of fish continued until the <br /> <br />summer of 2000. <br />Average growth rates of razorback sucker stocked in April 1999 were slightly <br />higher in Baeser Bend than in The Stirrup and Above Brennan. In Baeser Bend, <br />~ razorback sucker grew from an average length of 111 mm at stocking to 341 mm in <br />September (Figure 15). Weight gains averaged 442 grams (15.5 g at stocking to 457 g) <br />or about 100 grams more than weight gains in The Stirrup and Above Brennan. Growth <br />~ rates for razorbacks stocked in April averaged 1.4 mm/day and 2.7 grams/day (Figure <br />16). <br />Razorback sucker that were stocked in July grew at the Ouray National Fish <br />1 <br />Hatchery from an average length of 115 mm in April to 180 mm in July (Ouray National <br />Fish Hatchery 1999). In September, their average length was 286 mm (Figure 15). <br />~ Fish stocked in July averaged 46 grams of weight gain (15.5 in April to 61 grams in <br />15 <br /> <br />
